What HUMULIN is used for
HUMULIN is used to reduce high blood sugar (glucose) levels in patients with diabetes mellitus.
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 mellitus:
Type 1 diabetes - also called juvenile onset diabetes.
Type 2 diabetes - also called maturity onset diabetes.
Patients with type 1 diabetes always require insulin to control their blood sugar levels.
Some patients with type 2 diabetes may also require insulin after initial treatment with diet, exercise and tablets.
HUMULIN is identical to the insulin produced by the pancreas.
There are 3 different types of HUMULIN cartridges:
- HUMULIN R
- HUMULIN NPH
- HUMULIN 30/70.
Your doctor will tell you the type of HUMULIN that is best suited to you.
The duration of action of the insulin you inject will vary according to the type being used, the dose, injection site, blood flow, temperature and level of physical activity.
Your doctor may tell you to use a short acting human insulin such as HUMULIN R in combination with a longer acting human insulin such as HUMULIN NPH.
The abbreviation "rbe" indicates the method of genetic engineering used to manufacture the insulin.
This medicine is not addictive.
This medicine is available only with a doctor's prescription.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Before you use HUMULIN
When you must not use it
Do not use HUMULIN if:
- you have an allergy to:
- any medicine containing insulin
- any of the ingredients listed at the end of this leaflet.
Some of the symptoms of an allergic reaction may include:
- redness, swelling, rash and itching at the injection site
- rash, itching or hives on the skin
- shortness of breath
- wheezing or difficulty breathing
- swelling of the face, lips, tongue or other parts of the body.
The only time you would take this medicine if you have an allergy to it, is if your doctor has you on a desensitisation program to minimise allergic reactions.
- you are experiencing low blood sugar levels (a "hypo").
If you have a lot of hypos discuss appropriate treatment with your doctor.
Do not use this medicine after the expiry date on the pack or if the packaging is torn or shows signs of tampering. If it has expired or is damaged, return it to your pharmacist for disposal.
If you are not sure whether you should start using this medicine, talk to your doctor.
Before you start to use it
Tell your doctor if you have any allergies to any other medicines, foods, preservatives or dyes.
Tell your doctor if you have or have had any of the following medical conditions:
- kidney problems
- liver problems
- overactive thyroid glands (hyperthyroidism)
- overactive adrenal glands (Cushing's Syndrome)
- enlargement of the face, hands and feet (acromegaly)
- a tumour of the adrenal gland (phaeochromocytoma)
- fluid retention especially in the hands, ankles or feet
- heart disease.
Tell your doctor if you are pregnant or plan to become pregnant. Pregnancy may make managing your diabetes more difficult. Insulin needs usually decrease during the first three months of pregnancy and increase during the last six months. Your doctor can discuss with you the risks and benefits involved.
Tell your doctor if you are breast-feeding or plan to breast-feed. Your doctor/pharmacist can discuss with you the risks and benefits involved.
If you have not told your doctor about any of the above, tell them before you start using HUMULIN.
Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.
Some medicines may affect the way HUMULIN works.
- oral hypoglycaemic medicines that are used to treat type 2 diabetes
- medicines that affect your metabolism (corticosteroids such as prednisone, cortisone)
- medicines used for oral contraception
- medicines used in thyroid replacement therapy
- certain medicines used to treat tuberculosis, such as isoniazid
- medicines such as aspirin or other salicylates
- certain medicines used to treat depression
- certain medicines used to treat asthma, such as salbutamol or terbutaline
- some antibiotics
- certain medicines used to treat high blood pressure or other heart conditions
- certain medicines used to treat people with growth disorders and tumours, such as octreotide
- thiazolidinediones (TZDs), also used to treat type 2 diabetes; when used with insulin there may be an increased risk of fluid retention and heart disease.
Tell your doctor about any other medicines that you are taking. This is very important. Your doctor will advise you if it is all right to keep taking them or if you should stop taking them.
Your doctor and pharmacist have more information on medicines to be careful with or avoid while using this medicine.
How to use HUMULIN
Your doctor, diabetes education nurse or pharmacist will have shown you how to use HUMULIN.
Carefully follow all the directions. They may differ from the information contained in this leaflet.
Do not inject HUMULIN into a vein or muscle.
Any change in dose or type of insulin should be made cautiously and only under medical supervision. If you change the type of insulin that you use, you may have to use more or less than before. This may happen with the first dose or over a period of time.
More frequent monitoring is recommended when changing insulin dose or type.
If you do not understand the instructions, ask your doctor or pharmacist for help.
How much to use
Your doctor will tell you how much HUMULIN you need to use each day.
It is very important that you manage your diabetes carefully. Too much or too little insulin can cause serious effects.
When to use it
Your doctor will tell you when to use HUMULIN.
How to use it
Checking your HUMULIN cartridge
Check the HUMULIN cartridge before each preparation and injection. Make sure you are using the correct cartridge.
HUMULIN 3.0 mL cartridges are only for use with the HumaPen. The manufacturer's instructions for the HumaPen injection delivery systems should be followed for loading the cartridge, attaching the needle and administering the insulin injection.
Do not use HUMULIN NPH or HUMULIN 30/70 suspension if it is no longer a cloudy white suspension after shaking or has solid pieces in it.
Do not use HUMULIN if the cartridge appears frosted. This can occur when solid white particles stick to the bottom and walls, after mixing. If this occurs, please return to the place of purchase for exchange.
Do not use HUMULIN R if it is thickened, coloured or has solid pieces in it.
Always check your insulin injection device for insulin flow (priming) before use. The priming procedure may highlight a malfunction with your insulin injection device. Priming also removes any air bubbles and helps indicate whether or not a needle is broken.
Preparing a dose
- Wash your hands.
- If your cartridge is already inside your pen, check the amount of insulin remaining. 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 HUMULIN is left by looking at the gauge on the side of the cartridge. The distance between each mark on the gauge is about 20 units. If there is not enough for your dose, change the cartridge.
- If you are using a cloudy insulin, just before use, roll the cartridge/pen between the palms 10 times and invert 10 times until the suspension appears uniformly cloudy or milky. Do not shake. Inspect the cartridge for uniform mixing and repeat the above steps if necessary.
- Put the cartridge into the pen.
- Attach a needle.
Checking for insulin flow (Priming)
- Remove the needle cap.
- Set the dose to 1 or 2 units.
- Hold the pen with the needle pointing up and tap the side of the pen so that any bubbles float to the top.
- With the pen still pointing up, press the injection button. Do this until a drop or stream of HUMULIN comes out of the needle. This is very important to help make sure you inject the correct dose.
- Repeat steps 2-4 until you see a drop of insulin at the needle tip. 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 2-4 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 education nurse or pharmacist to obtain a replacement pen.
- Only dial up your required dose after you see a drop of insulin at the needle tip. There may still be some small air bubbles left in the cartridge. These are harmless.
- If the air bubble is too big, you should prime the cartridge again.
- If you need to put the pen down, make sure the needle does not touch anything.
Injecting a dose
Choose a site for injection.
Inject HUMULIN in the upper arms, thighs, buttocks or abdomen.
Change the injection site so that the same position is not used more often than once a month. This will reduce the chance of local skin reactions developing.
Pinch the skin between two fingers, push the needle into the raised skin and inject the full dose of insulin under the skin.
Slowly count to 5 or 6 before pulling the needle out.
Apply gentle pressure over the injection site for several seconds.
Do not rub the area.
Using the outer needle cap, unscrew the needle and dispose of it safely into a yellow plastic sharps container.
Do not share needles, cartridges or pens.
Leave the cartridge in the pen until it needs to be replaced.
How long to use it
Do not stop using your insulin unless your doctor tells you to.
If you take too much (overdose) - Hypoglycaemia
Your blood sugar level may become too low (you may experience hypoglycaemia or a "hypo") if you:
- accidentally use too much HUMULIN
- have too much or unexpected exercise
- delay eating meals or snacks
- eat too little food
- are ill.
The first symptoms of mild to moderate hypos can come on suddenly. They may include:
- cold sweat, cool pale skin
- fatigue, drowsiness, unusual tiredness and weakness
- nervousness, anxious feeling, tremor, rapid heart beat
- confusion, difficulty concentrating
- excessive hunger
- vision changes
- headache, nausea.
Always carry some sugary food or fruit juice with you.
If you experience any of these symptoms of a hypo, immediately eat some sugary food or have a drink, e.g. lollies, biscuits or fruit juice.
Tell your relatives, friends, close workmates or carers that you have diabetes. It is important that they recognise the signs and symptoms of a hypo.
Make sure they know to give you some sugary food or fruit juice for mild to moderate symptoms of a hypo.
If you lose consciousness, make sure they know:
- to turn you on your side and get medical help immediately
- not to give you anything to eat or drink.
This is because you could choke.
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, eat some sugary food or have a drink as soon as you are conscious again.
If you do not feel better after this, contact your doctor, diabetes education nurse, or go Accident and Emergency at the nearest hospital. If you do not respond to glucagon treatment, you will have to be treated in a hospital.
See your doctor if you keep having hypo reactions, or if you have ever become unconscious after using insulin. Your insulin dose may need to be changed.
If a severe hypo is not treated, it can cause brain damage and death.
If you miss a dose - Hyperglycaemia
If you forget your insulin dose, test your blood sugar level as soon as possible.
If you are not sure what to do, talk to your doctor, diabetes education nurse or pharmacist.
Do not use a double dose of your insulin.
If it is almost time for your next dose, skip the dose you missed and use your next dose when you are meant to.
Otherwise, use it as soon as you remember, and then go back to using it as you would normally.
Your blood sugar levels may become high (hyperglycaemia) if you:
- miss doses of insulin or use less insulin than you need
- have uncontrolled diabetes
- exercise less than usual
- eat more carbohydrates than usual
- are ill or stressed.
High blood sugar levels over a long period of time can lead to too much acid in the blood (diabetic ketoacidosis).
Contact your doctor immediately if your blood sugar level is high or you recognise any of the following symptoms.
Symptoms of mild to moderate hyperglycaemia include:
- drowsy feeling
- 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
- high levels of glucose and acetone in the urine.
Symptoms of severe hyperglycaemia include:
- heavy breathing
- fast pulse
- nausea, vomiting
- loss of consciousness.
Severe hyperglycaemia can lead to unconsciousness and in extreme cases death if untreated.
Discuss any worries you may have about this with your doctor or pharmacist.
While you are using HUMULIN
Things you must do
Measure your blood sugar levels regularly.
Make sure all friends, relatives, workmates or carers know that you have diabetes.
It is important to keep using your medicine even if you feel well. This medicine helps to control your condition, but does not cure it.
Tell your doctor if you often have hypos (low blood sugar levels). Your doctor may need to adjust your insulin dose.
Always carry some sugary food or fruit juice with you. If you experience any of the symptoms of a hypo, immediately eat some sugary food or have a drink, e.g. lollies, biscuits or fruit juice.
Tell your doctor if you have trouble recognising the symptoms of hypos. Under certain conditions, the early warning signs of hypos can be different or less obvious. Your doctor may need to adjust your insulin dose.
Make sure that you tell every doctor, dentist, pharmacist or other health care professional who is treating you that you have diabetes and are using insulin.
Tell your doctor, diabetes education nurse or pharmacist if you are travelling. Ask your doctor for a letter explaining why you are taking injecting devices with you. Each country you visit will need to see this letter, so you should take several copies.
You may need to inject your insulin and eat your meals at different times because of time differences in and between countries.
You may not be able to get the same type of insulin in the country you are visiting.
Your doctor, diabetes education nurse or pharmacist can provide you with some helpful information.
Tell your doctor if you are having trouble/difficulty with your eyesight. Visual disturbances in uncontrolled diabetes are reversed during the early stages of treatment.
Once established on insulin, if your vision changes, see your doctor as soon as possible.
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are using HUMULIN.
If you become pregnant while using this medicine, tell your doctor immediately.
If you are about to have any blood tests, tell your doctor that you are using this medicine.
Keep all of your doctor's appointments so that your progress can be checked. Your doctor may do some tests from time to time to make sure the medicine is working and to prevent unwanted side effects.
Always carry a supply of HUMULIN cartridges and your pen with you.
Always carry something to show you have diabetes.
Things you must not do
Do not stop using your medicine unless your doctor tells you to.
Do not use this medicine if you think it has been frozen or exposed to excessive heat. It will not work as well.
Do not use empty cartridges again.
Do not use HUMULIN to treat any other complaints unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not adjust the dosage of your medicine without checking with your doctor.
Things to be careful of
Be careful driving or operating machinery until you know how the insulin affects you.
Tell your doctor if you drink alcohol. Alcohol may mask the symptoms of hypos.
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.
Tell your doctor if you are feeling particularly excited or upset. Emotional disturbances may change your insulin needs.
Tell your doctor if you are exercising more than usual. Exercise may lower your need for HUMULIN. Exercise may also speed up the effect of a dose of HUMULIN, especially if the exercise involves the area of injection site (e.g. the leg should not be used for injection prior to jogging or running).
Tell your doctor if your diet changes. Changes in diet may cause your insulin needs to change.
Tell your doctor, diabetes education nurse or pharmacist as soon as possible if you do not feel well while you are using HUMULIN. This medicine helps most people with type 1 or type 2 diabetes, but it may have unwanted side effects in a few people.
All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.
Do not be alarmed by the following lists of side effects. You may not experience any of them.
Ask your doctor, diabetes nurse educator or pharmacist to answer any questions you may have.
The most common side effect when using insulin is low blood sugar levels (a hypo).
Tell your doctor or pharmacist if you notice any of the following:
- hypos (mild to moderate)
- redness, swelling or itching at the injection site (local allergy) Usually these symptoms disappear within a few weeks during continued use.
- a depression or thickening of the skin around the injection site (lipodystrophy)
- fluid retention, particularly in the ankles, feet and hands (oedema).
This list includes the more common side effects of your medicine.
If any of the following happen, tell your doctor immediately or go to Accident and Emergency at your nearest hospital:
More severe symptoms of low blood sugar levels, including:
- seizures, fits or convulsions
- loss of consciousness.
Tell your relatives, friends, close workmates or carers that you have diabetes.
If a severe hypo is not treated, it can cause brain damage and death.
Tell your doctor immediately or go to Accident and Emergency at your nearest hospital if you notice any of the following:
- skin rashes over a large part of the body
- shortness of breath, wheezing
- swelling of the face, lips or tongue
- fast pulse
This list includes very serious side effects. You may need urgent medical attention or hospitalisation.
Tell your doctor if you notice anything that is making you feel unwell.
Other side effects not listed above may also occur in some people.
