7. Product details

1. Why am I using HUMALOG insulin?

HUMALOG insulins contain the active ingredient insulin lispro (rbe).

There are 3 different types of HUMALOG insulins available in cartridges:

  • HUMALOG
  • HUMALOG MIX25
  • HUMALOG MIX50

They all contain the same active ingredient but HUMALOG is a solution whereas HUMALOG MIX25 and HUMALOG MIX 50 are pre-mixed suspensions. Each will vary with how long they work in your body.

HUMALOG insulins are used to reduce high blood sugar (glucose) levels in patients with diabetes.

Diabetes is a condition in which your pancreas does not produce enough insulin to control your blood sugar level. Extra insulin is therefore needed.

There are two types of diabetes:

Type 1 diabetes - patients with type 1 diabetes always need insulin to control their blood sugar levels.

Type 2 diabetes - some patients with type 2 diabetes may also need insulin after initial treatment with diet, exercise, and tablets.

2. What should I know before I use HUMALOG insulin?

Warnings

Do not use HUMALOG insulins:

  • if you are allergic to insulin lispro, or any of the ingredients listed at the end of this leaflet. Always check the ingredients to make sure you can use this medicine.
  • when you have hypoglycaemia (low blood sugar).
  • HUMALOG MIX25 and HUMALOG MIX50 should not be used intravenously.

Check with your doctor if you:

  • have had an allergic reaction to any medicine which you have used previously to treat diabetes.
  • are using, or have used, another type or brand of insulin. This may affect the dose of HUMALOG insulin that you are prescribed.
  • have or have had kidney or liver disease. This may affect the dose of HUMALOG insulin that you are prescribed.
  • have or have had heart disease and are also taking thiazolidinediones a type of medicine used to treat type 2 diabetes (such as pioglitazone, rosiglitazone). You may be more at risk to develop fluid retention (oedema) especially in the hands, ankles, or feet, or heart failure while using HUMALOG insulin.
  • are taking any other medications.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Check with your doctor if you are pregnant or intend to become pregnant. Pregnancy may make managing diabetes more difficult. Insulin needs usually decrease during the first three months of pregnancy and increase during the last six months.

Talk to your doctor if you are breastfeeding or intend to breastfeed. It is not known if HUMALOG insulins are excreted in significant amounts in breast milk.

Children (under 18 years)

The use of HUMALOG MIX25 and HUMALOG MIX50 have not been studied in children under the age of 18.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins, or supplements that you buy without a prescription from your pharmacy, supermarket, or health food shop.

You may need a lower dose of HUMALOG insulin if you are also taking any of the following medicines:

  • other medicines that treat diabetes
  • aspirin or other salicylates
  • a group of antibiotics, known as sulfonamides, used to treat infections
  • certain medicines used to treat depression, such as monoamine oxidase inhibitors
  • certain medicines used to treat high blood pressure or other heart conditions, such as captopril, enalapril, angiotensin II receptor blockers, and beta blockers
  • certain medicines used to treat people with growth disorders and tumours, such as octreotide.

You may need a higher dose of HUMALOG insulin if you are also taking any of the following medicines:

  • medicines used for oral contraception ('the pill')
  • medicines that affect your metabolism (corticosteroids such as prednisone and cortisone)
  • medicines used in thyroid replacement therapy
  • certain antibiotics used to treat tuberculosis, such as isoniazid
  • certain medicines used to treat asthma, such as salbutamol or terbutaline
  • certain medicines used to treat schizophrenia, bipolar disorder, or nausea and vomiting, such as phenothiazines
  • certain medicines used to treat hormone-related disorders, such as danazol.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins, or supplements you are taking and if these affect HUMALOG insulins.

4. How do I use HUMALOG insulin?

How much to use

Your doctor will tell you what dose of HUMALOG insulin you need to use each day.

When to use HUMALOG insulin

  • Your doctor will tell you when to use HUMALOG insulin.
  • You should normally use HUMALOG insulins immediately (or up to 15 minutes) before a meal.
  • When necessary, HUMALOG can be used within 20 minutes after the start of a meal. Do not use HUMALOG MIX 25 or HUMALOG MIX50 after the start of a meal.

How to use HUMALOG insulins

HUMALOG should be used by subcutaneous injection via a re-useable pen or insulin pump.

HUMALOG insulins in a re-useable pen

HUMALOG, HUMALOG MIX25 and HUMALOG MIX50 cartridges may be used with the HumaPen.

The manufacturer's instructions for the HumaPen delivery systems should be followed for loading the cartridge, attaching the needle, and administering the insulin injection.

Check your cartridge

  1. Check the cartridge before using. Make sure you are using the correct cartridge. The solution of HUMALOG should be clear and colourless. The suspension in HUMALOG MIX25 and HUMALOG MIX50 cartridges should be white and cloudy or milky.

Prepare dose

  1. Wash your hands.
  2. HUMALOG MIX25 and HUMALOG MIX50 cartridges must be rolled between your palms ten times and inverted ten times until the contents are uniformly mixed. Do not shake as this may cause frothing which may interfere with the correct measurement of the dose.
  3. Inspect the cartridge for uniform mixing and repeat the above steps if necessary.
  4. Put the cartridge into the pen.
  5. Attach a needle. Remove the outer needle shield. Do not throw it away.
  6. Pull off the inner needle shield and throw it away.

Checking for insulin flow (Priming)

Always prime your pen before injecting a dose.

Priming may highlight a malfunction with the pen or needle. It also removes any air bubbles and ensures that you receive the correct dose.

  1. Set the dose to 2 units.
  2. Hold the pen with the needle pointing up and tap the side of the pen so that any bubbles float to the top.
  3. With the pen still pointing up, press the injection button. Priming is complete when a stream of insulin comes out of the needle. This is very important to ensure the correct dose is injected.
  4. If a drop of insulin still does not appear, hold the pen with the needle facing upwards and away from your face. Attach a new needle. Repeat steps 1 - 3 again. If you are still unable to get insulin flowing out of the needle, do not use the pen. Return the pen to your doctor, diabetes educator or pharmacist to obtain a replacement pen.
  5. Only after seeing a stream of insulin at the needle tip should you proceed to dial up your required dose. There may still be some small air bubbles left in the cartridge. These are harmless.
  6. If the air bubble is too big, you should prime the pen again.

Injecting dose

HUMALOG insulins should be injected under the skin (subcutaneously). Your doctor or diabetes educator will show you how to properly inject HUMALOG.

Under no circumstances should HUMALOG MIX25 or HUMALOG MIX50 be injected intravenously (directly into your veins).

  1. Dial your prescribed dose.
  2. Choose a site for injection (abdomen or thighs). Use of injection sites should be rotated so that the same spot is not used more than once a month.
  3. Stabilise the skin by spreading it or gently pinching up a large area of skin. Insert the needle as instructed by your doctor.
  4. Press the knob. Count to 5 slowly before pulling the needle out.

After injecting

  1. Release the skin and apply gentle pressure over the injection site for several seconds. Do not rub the area.
  2. Using the outer needle cap, unscrew the needle and dispose of it safely into a sharps container. Do not re-use the needle.
  3. Leave the cartridge in the pen until it needs to be replaced.

Further injections

  • Stop using the cartridge if the leading edge of the plunger has gone to, or beyond, the left side of the gauge on the side of the cartridge.
  • You can see how much insulin is left by looking at the gauge on the side of the cartridge. The scale on the cartridge shows how many units you have left. If there is not enough for your dose, change the cartridge.
  • Do not mix any other insulin in your cartridge. Once the cartridge is empty, do not use it again.

HUMALOG in a subcutaneous infusion pump

HUMALOG may be given under the skin by means of an insulin infusion pump. HUMALOG MIX25 and HUMALOG MIX50 should never be used in a pump.

HUMALOG should never be mixed with any other insulin when used in a pump.

  1. Use the type of pump system recommended by your doctor, read and follow the instructions that accompany your pump.
  2. Before inserting the needle, wash your hands and the skin where the needle is to be inserted. This will help prevent infection at the infusion site.
  3. Be sure to use the correct reservoir and catheter for your pump.
  4. When you are filling a new syringe, do not leave large air bubbles in either the syringe or the catheter.
  5. Change the syringe and catheter at least every 48 hours (2 days).
  6. Follow your doctor, nurse, diabetes educator, or pharmacist's advice about the basal infusion rate and the mealtime insulin boluses to be taken.
  7. Measure blood sugar levels regularly. This will help check that your insulin pump is working correctly for you, and to detect possible malfunction of the insulin pump.
  8. In case of infusion pump system failure, you should always carry a spare cartridge of HUMALOG and a pen, or an alternative insulin delivery system, for injection under the skin.

If you forget to use HUMALOG insulin

Test your blood sugar level as soon as possible.

If you use less HUMALOG insulin than you need, a high blood sugar level (hyperglycaemia) may occur.

Use it as soon as you remember, and then go back to using it as you would normally. Do not use a double dose of HUMALOG insulin.

If you are not sure what to do, talk to your doctor, diabetes educator, or pharmacist.

If you use too much HUMALOG insulin

Hypoglycaemia (low blood sugar) may occur if you have used more HUMALOG insulin than you need. Check your blood sugar.

If your blood sugar is low (mild hypoglycaemia) eat glucose tablets, sugar or drink a sugary drink. Then eat fruit, biscuits, or a sandwich. This will often resolve mild hypoglycaemia or a minor insulin overdose.

If you get worse and your breathing is shallow and your skin gets pale, you may need urgent medical attention.

You should immediately:

  • phone the Poisons Information Centre (by calling Australia: 13 11 26 / New Zealand: 0800 764 766), or
  • contact your doctor, or
  • go to the Emergency department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

5. What should I know while using HUMALOG insulin?

Things you should do

  • Remind any doctor, dentist, pharmacist, and diabetes educator you visit that you are using HUMALOG insulin.
  • Monitor your blood sugar levels regularly to ensure that your dose of HUMALOG insulin is appropriate. More frequent monitoring is recommended when changing insulin dose or type, or when you start taking a new medicine.
  • Always carry a supply of HUMALOG insulin cartridges and your pen.
  • Always carry something to show you have diabetes.
  • Always carry glucose or sugary foods in case you develop hypoglycaemia (low blood sugar).

Tell your doctor

  • if you become pregnant or start breastfeeding while using HUMALOG insulin.
  • if you notice changes to your eyesight. This may be a sign that your diabetes is not being controlled appropriately.
  • Tell your doctor, pharmacist, or diabetes educator if you plan to travel. You may need to carry a letter explaining why you are taking injecting devices with you. Your doctor, pharmacist, or diabetes educator can provide you with some helpful information.

Things you should not do

  • Do not use HUMALOG insulin when you have hypoglycaemia (low blood sugar) as it will make it worse.
  • Do not stop using HUMALOG insulin without first checking with your doctor.
  • Do not change your insulin (dose or type) without first checking with your doctor.
  • Do not give your HUMALOG insulin to anyone else, even if they have the same condition as you. Your doctor has prescribed HUMALOG insulin specifically for you.
  • Do not mix HUMALOG insulin with any other animal or human insulin preparations.
  • Do not share needles, cartridges, or pens.
  • Do not re-use needles.
  • Do not store your insulin pen with the needle attached. This will ensure that your insulin will not become contaminated, and prevent leakage, the re-entry of air, and potential needle clogs.
  • Do not use HUMALOG insulin if the packaging is torn or shows signs of tampering.
  • Do not use HUMALOG if the solution is cloudy, thickened, coloured, or has solid pieces in it, as it may no longer be good to use.
  • Do not use HUMALOG MIX25 or HUMALOG MIX50 if the suspension is no longer cloudy white after gentle shaking or if it has solid pieces in it, as it may no longer be good to use.
  • Do not use HUMALOG insulin if the cartridge appears frosted, as it may no longer be good to use.
  • Do not use HUMALOG insulin if you think it has been frozen or exposed to excessive heat. It will not work as well.

Hypoglycaemia (low blood sugar)

Your blood sugar level may become too low if you:

  • use too much HUMALOG insulin
  • exercise too much or excessively
  • delay eating meals or snacks
  • eat too little food
  • are ill.

Symptoms of mild to moderate hypoglycaemia can come on suddenly, and may include:

  • weakness, trembling or shaking
  • sweating
  • light headedness/headache
  • lack of concentration
  • behaviour change
  • dizziness
  • tearfulness/crying
  • irritability
  • numbness around the lips/fingers
  • hunger

Tell your doctor if you have trouble recognising these symptoms, if you often have hypoglycaemia or if you have ever become unconscious after using insulin. More frequent monitoring of your blood sugar level may be recommended, or your dose of HUMALOG insulin may need to be changed.

Recognising these mild to moderate symptoms early may allow you to take the necessary steps to avoid more serious hypoglycaemia.

Always carry some sugary food or drink with you.

If you experience symptoms of mild to moderate hypoglycaemia, immediately eat some sugary food or drink, such as jelly beans, fruit juice or glucose tablets.

If you do not feel better after eating/drinking some sugary food or drink, contact your doctor or go to the Emergency department at your nearest hospital.

Tell your relatives, friends, close workmates, or carers that you have diabetes.

It is important that they also recognise the signs and symptoms of hypoglycaemia.

Make sure they know to give you some sugary food or drink for mild to moderate symptoms of hypoglycaemia.

Severe symptoms of hypoglycaemia may include:

  • disorientation
  • seizures, fits, or convulsions
  • loss of consciousness.

If you lose consciousness, make sure your relatives, friends, close workmates, or carers know:

  • to turn you on your side and get medical help immediately.
  • not to give you anything to eat or drink to avoid choking.

Severe hypoglycaemia can lead to unconsciousness and in extreme cases death if not treated.

An injection of the hormone glucagon may speed up recovery from unconsciousness. This can be given by a relative, friend, workmate, or carer who knows how to give it.

If glucagon is used, have some sugary food or drink as soon as you are conscious again.

Hyperglycaemia (high blood sugar)

Your blood sugar levels may become too high if:

  • you miss doses of HUMALOG insulin or use less than you need
  • you have uncontrolled diabetes
  • you exercise less than usual
  • you eat more carbohydrates than usual
  • you are ill or stressed
  • your insulin pump is not working correctly.

Contact your doctor if your blood sugar level is too high and you experience any of the following symptoms. High blood sugar levels over a long period of time can lead to too much acid in the blood (diabetic ketoacidosis).

  • drowsiness
  • flushed face
  • thirst, loss of appetite
  • fruity odour on the breath
  • blurred vision
  • passing larger amounts of urine than usual
  • getting up at night more often than usual to pass urine
  • nausea and vomiting.

Contact your doctor or the Emergency Department immediately if your blood sugar level is too high and you experience any of the following severe symptoms. Severe hyperglycaemia can lead to unconsciousness and in extreme cases death (if left untreated).

  • heavy breathing
  • fast pulse
  • nausea, vomiting
  • dehydration
  • loss of consciousness.

Illness

Tell your doctor if you are ill.

Illness, especially with nausea and vomiting, may cause your insulin needs to change. Even if you are not eating, you still require insulin. You and your doctor should design an insulin plan for those times when you are sick.

Emotional disturbances

Tell your doctor if you are feeling particularly excited, upset, or stressed.

Emotional disturbances may impact your dose of HUMALOG insulin.

Exercise

Exercise may lower your need for insulin. Exercise may also make insulin work more quickly, especially if the exercise involves the area around the injection site (e.g., the leg should not be used as an injection site prior to jogging or running).

Tell your doctor if you are exercising more than usual, as your dose of HUMALOG insulin may need to change.

Diet

Changes to your diet may cause your insulin needs to change.

Tell your doctor before making any significant changes to your diet (e.g., removing carbohydrates).

Injection site

If you inject HUMALOG insulin in the same place, the fatty tissue may shrink (lipoatrophy) or thicken (lipohypertrophy).

Lumps under the skin may also be caused by build-up of a protein called amyloid (cutaneous amyloidosis).

To help prevent these skin changes, do not use the same place for injection more often than once a month.

HUMALOG insulin may not work very well if you inject into a lumpy, shrunken, or thickened area. Avoid injecting into these areas.

Tell your doctor if you are currently injecting into these affected areas before you start injecting in a different area.

Your doctor may tell you to measure your blood sugar more frequently, and to adjust your dose of HUMALOG insulin or other antidiabetic medications.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how HUMALOG insulins affect you.

Do not drive if you feel like your blood sugar level is low.

Hypoglycaemia (low blood sugar) may impair your ability to concentrate or react while driving.

Drinking alcohol

Tell your doctor if you drink alcohol.

Alcohol may mask the symptoms of hypoglycaemia (low blood sugar) and make it more difficult to recognise them.

Alcohol may also affect the dose of HUMALOG insulin that you are prescribed.

Looking after your medicine

  • Keep your cartridges in a fridge between 2°C - 8°C. Do not freeze.
  • When the cartridge has been inserted into the pen, the cartridge pen combination should not be kept in the fridge. You may keep the cartridges unrefrigerated (below 30°C) for up to 28 days while you are using them.
  • Dispose of unrefrigerated cartridges after 28 days even if they still contain insulin.
  • Do not store the cartridges in the bathroom or near a sink.
  • Do not put the cartridges near heat or in the sun.
  • Keep it where young children cannot reach it.

When to discard your medicine

Discard cartridges after the expiry date (month, year) stamped on the label has passed.

Getting rid of any unwanted medicine

If you no longer need to use this medicine or it is out of date, take it to any pharmacy for safe disposal.

Empty cartridges and needles should be disposed of in a sharps container or similar puncture proof container composed of hard plastic or glass.

Ask your doctor, nurse, pharmacist or diabetes educator where you can dispose of the container once it is full.

6. Are there any side effects?

All medicines can have side effects. If you do experience any side effects, most of them are minor and temporary. However, some side effects may need medical attention.

See the information below and, if you need to, ask your doctor or pharmacist if you have any further questions about side effects.

BRAND INFORMATION

Brand name

Humalog, Humalog Mix25, Humalog Mix50

Active ingredient

Insulin lispro; Insulin lispro protamine

Schedule

S4

 

1 Name of Medicine

Insulin lispro (rbe).

2 Qualitative and Quantitative Composition

The Humalog range consists of three presentations:

Humalog.

Insulin lispro solution [recombinant DNA origin] is an aqueous solution of insulin lispro ([Lys (B28), Pro (B29)] human insulin analogue, adjusted to pH 7.0 to 7.8. It also contains metacresol, glycerol, dibasic sodium phosphate heptahydrate, zinc oxide and water for injection. Hydrochloric acid and sodium hydroxide may be used to adjust pH.
Humalog is available as a clear, colourless solution for parenteral administration in a concentration of 100 units/mL in 10 mL vials, 3 mL cartridges and 3 mL prefilled insulin delivery devices (Humalog KwikPen).

Humalog Mix25.

25% insulin lispro and 75% insulin lispro protamine suspension (NPL) [recombinant DNA origin] is a mixture of insulin lispro, a rapid-acting blood glucose lowering agent and insulin lispro protamine suspension, an intermediate-acting blood glucose lowering agent, adjusted to pH 7.0 to 7.8.
Humalog Mix25 is available as a white suspension for parenteral administration in a concentration of 100 units/mL in 3 mL cartridges and 3 mL prefilled insulin delivery devices (Humalog Mix25 KwikPen).

Humalog Mix50.

50% insulin lispro and 50% insulin lispro protamine suspension (NPL) [recombinant DNA origin] is a mixture of insulin lispro, a rapid-acting blood glucose lowering agent and insulin lispro protamine suspension, an intermediate-acting blood glucose lowering agent, adjusted to pH 7.0 to 7.8.
Humalog Mix50 is available as a white suspension for parenteral administration in a concentration of 100 units/mL in 3 mL cartridges and 3 mL prefilled insulin delivery devices (Humalog Mix50 KwikPen).
Humalog Mix25 and Humalog Mix50 also contain metacresol, phenol, glycerol, dibasic sodium phosphate heptahydrate, protamine sulfate, zinc oxide and water for injection. Hydrochloric acid and sodium hydroxide may be used to adjust pH.
Humalog is a Lilly human insulin analogue. It differs from other insulins because it has a unique structure, a very quick onset of action and a shorter duration of activity. Humalog Mix25 and Humalog Mix50 combine the quick onset of action of Humalog with an extended duration of activity attributable to the intermediate acting component of the mixture. Humalog, Humalog Mix25 and Humalog Mix50 should be given immediately (up to 15 minutes) before a meal. When necessary, Humalog can be given soon after meals (within 20 minutes of the start of a meal). The safety and efficacy of Humalog Mix25 and Humalog Mix50 given after a meal has not been established.

In adults, Humalog, Humalog Mix25 and Humalog Mix50 can be given immediately (up to 15 minutes before a meal). When necessary, Humalog can be given soon after meals (within 20 minutes of the start of the meal). The safety and efficacy of Humalog Mix25 and Humalog Mix50 given after a meal has not been established.
In patients with type 2 diabetes, Humalog may be administered in combination therapy with oral sulfonylurea agents.

Children.

In clinical studies involving children and adolescents (ages 3 to 19 years), Humalog has been shown to be safe, effective and well tolerated.
Humalog can be given immediately (up to 15 minutes before a meal). When necessary, Humalog can be given soon after meals (within 20 minutes of the start of the meal). The safety and efficacy of Humalog Mix25 and Humalog Mix50 in children has not been established.

General.

During changes to a patient's insulin regimen, increase the frequency of glucose monitoring.
Humalog should be given by subcutaneous injection. It may also be administered intravenously.
Humalog Mix25 and Humalog Mix50 should only be given by subcutaneous injection. It should not be administered intravenously. The safety and efficacy of Humalog Mix25 and Humalog Mix50 given after a meal has not been established. The rapid onset and early peak activity of Humalog is observed following the subcutaneous administration of Humalog Mix25 and Humalog Mix50. The duration of action of the insulin lispro protamine suspension (NPL) component of Humalog Mix25 and Humalog Mix50 is similar to that of basal insulin NPH.
Subcutaneous administration should be in the abdomen or thighs. The injection sites should be rotated so that the same site is not used more than approximately once a month in order to reduce the risk of lipodystrophy and localised cutaneous amyloidosis. Do not inject into areas of lipodystrophy or localised cutaneous amyloidosis.
Care should be taken when injecting Humalog Mix25 and Humalog Mix50 to ensure that a blood vessel has not been entered. After injection, the site of injection should not be massaged.
The time course of action of any insulin may vary considerably in different individuals or at different times in the same individual. As with all insulin preparations, the duration of action of Humalog is dependent on dose, site of injection, blood supply, temperature and physical activity.
Humalog should not be considered as clinically equivalent to human insulin as the time to onset and time course of action are different compared with regular human insulin (see Section 5 Pharmacological Properties).
As Humalog has a time activity profile that is different from other insulins, patients previously stabilised on other insulin products should be titrated cautiously with Humalog, under medical supervision (see Section 4.4 Special Warnings and Precautions for Use).
Humalog may be administered in combination regimens with Humulin NPH.
Humalog has been mixed with Humulin NPH. In normal volunteers, mixing Humalog with Humulin NPH immediately prior to subcutaneous injection does not affect the rapid absorption of Humalog, compared to administration of the two insulins as separate injections. There is a lack of systematic experience, in diabetic patients, concerning the mixing of Humalog with other insulins. Humalog should not be mixed with any other animal or human insulin preparations. Humalog Mix25 or Humalog Mix50 should not be mixed with other insulins.

Instructions for use/ handling.

To prevent the possible transmission of disease, each Humalog KwikPen or cartridge must be used by one patient only, even if the needle is changed.
Humalog should be used as a multiuse vial in individual patients only.

Humalog - use in continuous subcutaneous infusion pumps.

The compatibility of Humalog has been studied in MiniMed and Accu-check (formerly Disetronic) insulin infusion pump systems (see Section 5.1 Pharmacodynamic Properties, Clinical trials). Humalog should be used in pumps according to the manufacturer's directions. The correct reservoir and catheter for the pump should be used and the entire infusion set (including the syringe and its contents) should be changed every 48 hours. When used with an insulin infusion pump, Humalog should not be mixed with any other insulin.
Patients should ensure they have access to an alternative device at all times in case of pump failure (see Section 4.4 Special Warnings and Precautions for Use).
Humalog Mix25 and Humalog Mix50 should not be used in pumps.

Humalog Mix25 and Humalog Mix50 cartridges.

Cartridges should be rolled between the palms 10 times. Holding the cartridge by one end, invert it 180° slowly 10 times to allow the glass bead to travel the full length of the cartridge with each inversion. Cartridges should not be shaken vigorously as this may cause frothing which may interfere with the correct measurement of the dose. The insulin should look uniformly cloudy after mixing. If it does not, the above steps should be repeated until the contents are mixed. Cartridges of insulin should be examined frequently and should not be used if the insulin substance (the white material) remains visibly separated from the liquid after mixing. Cartridges of insulin should not be used if there are clumps in the insulin after mixing or if solid white particles stick to the bottom or wall of the cartridge, giving a frosted appearance.

Humalog Mix25 and Mix50 KwikPens.

KwikPen prefilled insulin pen delivery devices should be rolled between the palms 10 times. Holding the device by one end, invert it 180° slowly 10 times to allow the glass bead to travel the full length of the cartridge with each inversion. The devices should not be shaken vigorously as this may cause frothing which may interfere with the correct measurement of the dose. The insulin should look uniformly cloudy after mixing. If it does not, the above steps should be repeated until the contents are mixed. KwikPen prefilled insulin pen delivery devices should be examined frequently and should not be used if the insulin substance (the white material) remains visibly separated from the liquid after mixing. KwikPen prefilled insulin pen delivery devices should not be used if there are clumps in the insulin after mixing or if solid white particles stick to the bottom or wall of the cartridge, giving a frosted appearance. For instructions on how to administer the insulin, refer to the manufacturer's instructions for the insulin pen delivery device.

4.3 Contraindications

Hypoglycaemia.
Hypersensitivity to insulin lispro or one of its excipients.
Humalog Mix25 and Humalog Mix50 should not be given intravenously.

4.4 Special Warnings and Precautions for Use

General.

Any change in an insulin or human insulin analogue regimen should be made cautiously and only under medical supervision with increased frequency of glucose monitoring. Changes in strength, brand (manufacturer), type (regular, NPH, lente, etc.), species (animal, human, human insulin analogue) and/or method of manufacture (recombinant DNA versus animal source insulin) may result in the need for a change in dosage.
The shorter acting Humalog should be drawn into the syringe first, to prevent contamination of the vial by the longer acting insulin. Mixing of the insulins ahead of time or just before the injection should be on advice of the doctor. However, a consistent routine must be followed.
Patients using any of the Humalog range of insulins may require a change in dosage from that used with their usual insulins. If dosage adjustment is needed, it may occur with the first dose or during the first several weeks or months.
Patients whose glycaemic control is greatly improved, e.g. by flexible insulin therapy, may lose some or all of the warning symptoms of hypoglycaemia and should be advised accordingly.
A few patients who have experienced hypoglycaemic reactions after transfer from animal source insulin to human insulin have reported that the early warning symptoms of hypoglycaemia were less pronounced or different from those experienced with their previous insulin.
Some studies with human insulin have shown increased levels of circulating insulin in patients with renal and/or hepatic dysfunction. Careful glucose monitoring and dose adjustments of insulins, including Humalog, may be necessary.
Thiazolidinediones (TZDs) in combination with insulin are associated with an increased risk of oedema and heart failure; especially in patients with underlying cardiac disease.
Insulin requirements may be increased during illness or emotional disturbances.
Adjustment of dosage may also be necessary if patients undertake increased physical activity or change their usual diet.
Humalog Mix25 or Humalog Mix50 should under no circumstances be administered intravenously. Mixing of Humalog Mix25 or Humalog Mix50 with other insulins has not been studied. Therefore, Humalog Mix25 or Humalog Mix50 should not be mixed with other insulins.

Injection technique.

Patients must be instructed to perform continuous rotation of the injection site to reduce the risk of developing lipodystrophy and cutaneous amyloidosis. There is a potential risk of delayed insulin absorption and worsened glycaemic control following insulin injections at sites with these reactions. A sudden change in the injection site to an unaffected area has been reported to result in hypoglycaemia. Blood glucose monitoring is recommended after the change in the injection site, and dose adjustment of antidiabetic medications may be considered.

Subcutaneous insulin infusion pumps.

Malfunction of the insulin pump or infusion set (including pump malfunction, infusion set occlusion, leakage, disconnection or kinking) or insulin degradation can rapidly lead to hyperglycaemia and ketosis. Prompt identification and correction of the cause of hyperglycaemia or ketosis is necessary and interim subcutaneous injections with Humalog may be required. Patients using continuous subcutaneous infusion pump therapy must be trained to administer insulin by injection and have alternate insulin therapy and device available in case of pump failure (see Section 4.2 Dose and Method of Administration).

Use in hepatic impairment.

Insulin requirements may be reduced in the presence of hepatic impairment.

Use in renal impairment.

Insulin requirements may be reduced in the presence of renal impairment.

Use in the elderly.

No data available.

Paediatric use.

The safety and efficacy of Humalog Mix25 and Humalog Mix50 in patients less than 18 years of age has not been established.

Effects on laboratory tests.

No data available.

4.5 Interactions with Other Medicines and Other Forms of Interactions

The physician should be consulted when using other medication in addition to insulin lispro (see Section 4.4 Special Warnings and Precautions for Use).
Insulin requirements may be increased by drugs with hyperglycaemic activity, such as oral contraceptives, corticosteroids, thyroid replacement therapy, isoniazid, phenothiazines, danazol or beta-2 stimulants (such as salbutamol, terbutaline).
Insulin requirements may be reduced in the presence of drugs with hypoglycaemic activity, such as oral hypoglycaemics, salicylates (for example, aspirin), sulphonamides, certain antidepressants (monoamine oxidase inhibitors), certain angiotensin converting enzyme inhibitors (captopril and enalapril), angiotensin II receptor blockers, beta-blockers, octreotide and alcohol.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

No effects on male or female fertility have been observed in rats dosed subcutaneously with insulin lispro at dose levels up to 20 U/kg/day.
(Category A)
Humalog can be used during pregnancy. There is a large body of data which suggests that the use of Humalog during pregnancy is beneficial, and as safe as other forms of insulin therapy.
In a retrospective cohort study, the medical records of 496 women with type 1 or type 2 diabetes treated with Humalog for at least 1 month before conception and during at least the first trimester of pregnancy were reviewed to determine the rate of major congenital anomalies in their offspring. Outcomes of 533 pregnancies (542 offspring) showed the incidence of major congenital anomalies in the offspring was 5.4% (95% CI: 3.45%, 7.44%), consistent with previously published results for the offspring of women with type 1 and type 2 pregestational diabetes.
The safety and efficacy of Humalog Mix25 and Humalog Mix50 has not been established during pregnancy.
It is essential to maintain good control of the insulin treated patient (insulin dependent or gestational diabetes) throughout pregnancy. Insulin requirements usually fall during the first trimester and increase during the second and third trimesters. Patients with diabetes should be advised to inform their doctor if they are pregnant or are contemplating pregnancy. Careful monitoring of the patient is required throughout pregnancy. During the perinatal period, careful monitoring of infants born to mothers with diabetes is warranted.
A reproductive study in rats showed no adverse effects on pregnancy or foetal development when insulin lispro was injected subcutaneously once daily at doses up to 20 U/kg. Teratogenic potential has not been adequately assessed in rabbits, although one study showed no embryotoxic or teratogenic activity at subcutaneous doses up to 0.75 U/kg/day. There are, however, no adequate and well controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
Patients with diabetes who are lactating may require adjustments in insulin dose, diet or both. It is not known if insulin lispro is excreted in significant amounts in human milk. Many drugs, including human insulin, are excreted in human breast milk.

4.7 Effects on Ability to Drive and Use Machines

The patient's ability to concentrate and to react may be impaired as a result of hypoglycaemia. This may constitute a risk in situations where these abilities are of special importance (e.g. driving a car or operating machinery). Patients should be advised to take precautions to avoid hypoglycaemia while driving, this is particularly important in those who have reduced or absent awareness of the warning signs of hypoglycaemia or have frequent episodes of hypoglycaemia. The advisability of driving should be considered in these circumstances.

4.8 Adverse Effects (Undesirable Effects)

The preclinical safety profile indicates that Humalog is safe in the chronic treatment of diabetes in humans. The safety profile of Humalog has been assessed in a series of preclinical studies. In in vitro tests, including binding to insulin receptor sites and effects on growing cells, Humalog behaved in a manner that closely resembled human insulin. Toxicology studies produced no significant toxicity findings. Most importantly, and like human insulin, Humalog did not produce proliferative effects or tumours in organs and tissues when given at very high subcutaneous doses in chronic toxicity tests.

Hypoglycaemia.

Hypoglycaemia is the most frequent undesirable effect of insulin therapy. Severe hypoglycaemia may lead to loss of consciousness and, in extreme cases, death. The clinical studies on Humalog showed no difference between the frequency of symptomatic hypoglycaemia or the frequency of hypoglycaemic coma when compared to Humulin R; however, the studies did show a consistent, but not always significant, reduction of postprandial glycaemic excursion in patients using Humalog.

Allergic reactions.

Local allergy in patients occasionally occurs as redness, swelling and itching at the site of insulin injection. This condition usually resolves in a few days to a few weeks. In some instances, this condition may be related to factors other than insulin, such as irritants in the skin cleansing agent or poor injection technique. Systemic allergy, less common but potentially more serious, is a generalised allergy to insulin. It may cause rash over the whole body, shortness of breath, wheezing, reduction in blood pressure, fast pulse or sweating. Severe cases of generalised allergy may be life threatening.

Lipodystrophy.

Rarely, administration of insulin subcutaneously can result in lipoatrophy or lipohypertrophy. A change in injection technique may help alleviate the problem.

Spontaneous data.

Cases of oedema have been reported with insulin therapy, particularly if previous poor metabolic control is improved by intensified insulin therapy (see Section 4.4 Special Warnings and Precautions for Use).
Lipodystrophy and localised cutaneous amyloidosis at the injection site have occurred. Hyperglycaemia has been reported with repeated insulin injections into areas of lipodystrophy or localised cutaneous amyloidosis; hypoglycaemia has been reported with a sudden change to an unaffected injection site (see Section 4.4 Special Warnings and Precautions for Use).

Reporting suspected adverse effects.

Reporting suspected adverse reactions after registration of the medicinal product is important. It allows continued monitoring of the benefit-risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions at http://www.tga.gov.au/reporting-problems.

4.9 Overdose

Insulins have no specific overdose definitions because serum glucose concentrations are a result of complex interactions between insulin levels, glucose availability and other metabolic processes. Hypoglycaemia may occur as a result of an excess of insulin or insulin analogue relative to food intake and energy expenditure.
Hypoglycaemia may be associated with listlessness, confusion, palpitations, headache, sweating and vomiting.
Mild hypoglycaemic episodes will respond to oral administration of glucose or other sugar or saccharated products.
Correction of moderately severe hypoglycaemia can be accomplished by intramuscular or subcutaneous administration of glucagon, followed by oral carbohydrate when the patient recovers sufficiently. Patients who fail to respond to glucagon must be given glucose solution intravenously.
If the patient is comatose, glucagon should be administered intramuscularly or subcutaneously. However, glucose solution must be given intravenously if glucagon is not available or if the patient fails to respond to glucagon. The patient should be given a meal as soon as consciousness is recovered.
For information on the management of overdose, contact the Poisons Information Centre on 131126 (Australia).

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Mechanism of action.

The unique structure of Humalog, compared to regular human insulin, results in a faster rate of absorption from subcutaneous sites of injection, a more rapid effect and a shorter duration of action, more closely mimicking the normal physiological response.
Humalog has a very rapid onset of action, allowing it to be given immediately before a meal, compared to regular insulin, which should be given 30 minutes before a meal. In initial clinical pharmacology studies, the onset of action of Humalog was seen within 15 minutes of administration, while onset of action for regular insulin was 30 to 45 minutes following administration. Serum insulin levels peaked earlier with Humalog, corresponding to an earlier peak action of Humalog (approximately 1 hour) as compared to regular insulin (2 to 3 hours). The pharmacokinetics of Humalog translated into a shorter duration of activity when compared to regular insulin, approximately 3.5 to 4.5 hours for Humalog as compared with 5.5 to 7.5 hours for regular insulin.
Results of a glucose clamp study in healthy volunteers showed that the absorption and activity profiles of insulin lispro protamine suspension (NPL) are similar to those of human insulin isophane suspension (NPH). The pharmacokinetic and pharmacodynamic profiles of insulin lispro/ insulin lispro protamine suspension (NPL) mixtures were investigated in a separate glucose clamp study. The rapid activity of insulin lispro was maintained within each mixture. In addition, each mixture demonstrated a distinct pharmacokinetic and glucodynamic profile.
As with all insulin preparations, the time course of Humalog action may vary in different individuals, or at different times in the same individual, and is dependent on site of injection, blood supply, body temperature and physical activity. The primary activity of Humalog is the regulation of glucose metabolism.
In addition, insulins have several anabolic and anticatabolic actions on a variety of different tissues. In muscle and other tissues (except the brain), insulin causes rapid transport of glucose and amino acids intracellularly, promotes anabolism, and inhibits protein catabolism. In the liver, insulin promotes the uptake and storage of glucose in the form of glycogen, inhibits gluconeogenesis, and promotes the conversion of excess glucose into fat.

Clinical trials.

Eight pivotal studies were designed to evaluate the use of Humalog as a mealtime insulin using postprandial glucose control as the primary efficacy objective. These studies were designed to incorporate men and women of many racial/ ethnic heritages and cultural dietary patterns, aged 12 to 85 with new or previously treated type 1 or type 2 diabetes mellitus. In these trials, 2,247 patients received Humalog.
Four global, multicentre, clinical studies of Humalog (studies IOAA-IOAD) were designed to incorporate type 1 and type 2 patients who were already receiving insulin therapy and who had been treated with human insulin for at least 2 months prior to study entry. All four were 1 year, open label, randomised, parallel studies using Humulin R in a multiple daily injection, basal bolus therapeutic regimen as the active comparator (see Table 1).
Four global, multicentre, clinical studies of Humalog (studies IOAE-IOAH) were conducted to incorporate type 1 and type 2 patients who had never received insulin, to evaluate antibody formation in patients not previously treated with insulin, and to have larger studies of both type 1 and 2 patients previously treated with insulin (see Table 1).
The studies in new type 1 and type 2 patients, IOAE and IOAF, were 1 year, open label, randomised, parallel, studies using Humulin R as the active comparator. The choice of basal insulin was at the discretion of the investigator, either Humulin NPH or Humulin UL, and once chosen was the basal insulin for the entire study. The study design was identical to the earlier studies, IOAA-IOAD.
Studies IOAG and IOAH were 6 month, open label, randomised, crossover studies in type 1 and type 2 patients who were currently being treated with insulin and had been using human insulin for at least the previous 2 months. Humulin R was the active comparator. The choice of basal insulin was at the discretion of the investigator, either Humulin NPH or Humulin UL, and once chosen was the basal insulin for the entire study. The power of the crossover design, with each patient serving as his or her own control, and the large patient numbers allowed these two studies to provide the major conclusions (consistent with the conclusions of the first six studies) regarding the efficacy of Humalog on reduction of the postprandial glucose excursion in patients with diabetes. In addition, study IOAG demonstrated a significant reduction in the rate of hypoglycaemia, overall, as well as demonstrating significant reduction in nocturnal hypoglycaemia in patients receiving Humalog.
In all of the studies there were no clinically significant safety issues with Humalog. There was no evidence of increased immunogenicity of Humalog compared to Humulin R. Further studies are continuing on the immunogenicity of Humalog.
In the clinical trials of Humalog, approximately one-half to two-thirds of type 1 patients and approximately one-third of type 2 patients had their basal insulin in the morning. More than 90% of the patients having a morning dose of basal insulin had it mixed with their breakfast dose of Humalog.
Clinical studies have demonstrated significant improvement in postprandial glucose excursions without producing delayed postprandial hyperglycaemia and without an adverse effect on overall control as measured by haemoglobin A1c. Therapy with Humalog was also associated with no adverse impact on hypoglycaemia and, in fact, in the large studies with type 1 patients (those most at risk of hypoglycaemia) there was a reduction in the rate of hypoglycaemia overall and a reduction in nocturnal hypoglycaemia. Across all of the studies there were no significant safety issues.
Humalog is superior to regular human insulin in those measures that reflect rapid onset and shorter duration of action. Early studies showed no significant difference in overall glycaemic control, as measured by haemoglobin A1c, between Humalog and regular human insulin, either in patients established on insulin or in newly diagnosed patients. Haemoglobin A1c is improved with Humalog by varying the basal regimen, to compensate for preprandial hyperglycaemia and to make use of the reduced postprandial blood glucose levels provided by Humalog.
When used in MiniMed 507 or 507c subcutaneous infusion pumps, treatment with Humalog has been shown to result in statistically significant lower haemoglobin A1c levels compared to soluble insulin. It is not known if this is a clinically significant difference. Study IOEB was a 6 month, open label, crossover study of type 1 patients who were randomised to receive Humalog or regular human insulin for 12 weeks using the MiniMed 506 insulin infusion pump. After 12 weeks the patients were crossed over to the alternative treatment. All patients had used insulin infusion devices for at least 12 months prior to randomisation. Bolus doses of regular human insulin were given 15 to 30 minutes before meals and Humalog was given 0 to 5 minutes before meals. The primary efficacy variable for this study was the standard deviation in blood glucose values, which was shown to be smaller on Humalog. Haemoglobin A1c levels were determined at the end of the run-in phase, at 12 weeks and at the end of the study.
Study IOCR had a similar study design as study IOEB, except it was an 8 month study. The primary efficacy variable for this study was postprandial blood glucose values. Haemoglobin A1c levels were determined at baseline, at 16 weeks and at the end of the study.
Study IOEQ had a similar study design as study IOEB, however bolus doses of regular human insulin or Humalog were given immediately before meal onset. The primary efficacy variable for this study was postprandial blood glucose values. Haemoglobin A1c levels were determined at baseline, at 12 weeks and at the end of the study.
Studies IOEB and IOCR used pumps that were not registered in Australia. Study IOEQ used various pump models. Of these, the MiniMed 507 pump is registered in Australia. See Table 2.
In patients with type 2 diabetes on maximum doses of sulfonylurea agents, the addition of Humalog resulted in an improvement in haemoglobin A1c compared to patients continuing on sulfonylurea therapy alone. Study IOCE was a 2 month randomised, open label comparative study of Humalog, sulfonylurea and insulin NPH combinations. In this study, haemoglobin A1c levels were reduced by 1.6% with the combination of Humalog and sulfonylurea, when compared to baseline, in patients with fasting hyperglycaemia despite maximal doses of sulfonylurea.
