1. Why am I taking AMILOXYN?

AMILOXYN contains the active ingredient amoxicillin (as trihydrate).

AMILOXYN belongs to the penicillin group of antibiotics.

AMILOXYN is used to treat a range of infections caused by bacteria. These infections may affect the chest (e.g. pneumonia), tonsils (e.g. tonsilitis), sinuses (e.g. sinusitis), urinary and genital tract, skin and fleshy tissues.

AMILOXYN works by killing the bacteria that causes infections. AMILOXYN can also be used to prevent infection.

Your doctor may prescribe AMILOXYN for another use. If you want more information, ask your doctor.

There is no evidence that AMILOXYN is addictive.

2. What should I know before I take AMILOXYN?

Warnings

Do not take AMILOXYN if:

• you are allergic to amoxicillin (as trihydrate), penicillin or similar types of antibiotics (such as cephalosporins), or any of the ingredients listed at the end of this leaflet.
  Some of the symptoms of an allergic reaction may include skin rash, itching, difficulty in breathing and swelling of the face or tongue.
• the expiry date (EXP) printed on the pack has passed.
• the packaging is torn or shows signs of tampering.

Always check the ingredients to make sure you can take AMILOXYN.

Do not give AMILOXYN to anyone else, your doctor has prescribed it specifically for you and your condition.

Check with your doctor if you:

• have ever had an allergic reaction (such as a rash) to antibiotics or other substances in the past.
• are allergic to foods, dyes, preservatives or any other medicines.
• have glandular fever (mononucleosis) or lymphatic leukaemia.
• have any kidney or liver problems.
  The dosage of AMILOXYN may need to be changed or you may need to be given an alternative medicine.
• have to test your urine for sugar.
  AMILOXYN may affect the results of these tests.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor 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.

Talk to your doctor if you are breastfeeding or intend to breastfeed.

Your doctor will discuss with you the possible risks and benefits of taking AMILOXYN during pregnancy or while you are breastfeeding. AMILOXYN passes to your baby from breast milk.

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.

In particular, tell your doctor or pharmacist if you are taking any of the following:

• acenocoumarol, warfarin or other medicines used to prevent blood clots.
• medicines used to treat gout (e.g. probenecid or allopurinol).
• other antibiotics (e.g. tetracyclines). These may interfere with the actions of AMILOXYN.
• methotrexate (a medicine used to treat cancer or rheumatic diseases).
• contraceptive pill. As with other antibiotics, you may need to use extra birth control methods (e.g. condoms) while taking AMILOXYN.

Some medicines may interfere with AMILOXYN and affect how it works. Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect AMILOXYN.

4. How do I take AMILOXYN?

Follow the directions given to you by your doctor and pharmacist. Their directions may differ from the information contained in this leaflet.

Please read the direction label carefully. If you have any concerns about how to take AMILOXYN, talk to your doctor or pharmacist.

How much to take

Your doctor will tell you the dose of AMILOXYN you will need to take each day. This depends on the condition being treated and whether other medicines are being taken.

When to take it

Space the doses as evenly as possible throughout the day. For example, if you are taking AMILOXYN three times a day, take a dose about every eight hours.

How to take it

AMILOXYN can be taken with or without food. The effects of AMILOYXN are not changed by food.

Swallow AMILOXYN capsule whole with a full glass of water.

How long to take it for

Keep taking AMILOXYN until the course is finished or for as long as your doctor tells you.

Do not stop taking AMILOXYN just because you feel better as the infection can return.

Do not stop taking AMILOXYN, or change the dose, without first checking with your doctor.

If you forget to take AMILOXYN

If it is almost time for your next dose, skip the dose you missed and take your next dose at the normal time. Otherwise, take the missed dose as soon as you remember and then go back to taking AMILOXYN as directed by your doctor.

Do not take a double dose to make up for the dose you missed. Taking more than the prescribed dose can increase the chance of unwanted side-effects.

If you take too much AMILOXYN

If you think that you have taken too much AMILOXYN, you may need urgent medical attention.

You should immediately:

• drink plenty of water
• phone the Poisons Information Centre
  (by calling 13 11 26), or
• contact your doctor, or
• go to the Emergency Department at your nearest hospital.

Symptoms of overdose include mild to severe nausea, vomiting, cramps and diarrhoea.

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

5. What should I know while taking AMILOXYN?

Things you should do

• Take AMILOXYN exactly as your doctor has prescribed.
• Tell your doctor if, for any reason, you have not taken AMILOXYN exactly as directed. Otherwise your doctor may think that it was not working as it should and change your treatment unnecessarily.
• Tell your doctor if the symptoms of your infection become worse, or do not improve within a few days of starting AMILOXYN.
• Tell your doctor if you develop itching, swelling or a skin rash when taking AMILOXYN, do not take any more AMILOYXN and tell your doctor immediately.
• Tell your doctor if you develop severe diarrhoea either when taking AMILOXYN or within several weeks after treatment, tell your doctor immediately. Diarrhoea may mean you have a serious condition affecting your bowel. You may need urgent medical care. Do not take any medication to stop the diarrhoea (e.g. Lomotil^® or Imodium^®).
• Tell your doctor if you get a sore white mouth or tongue while taking or soon after stopping AMILOXYN.
• Tell your doctor if you have vaginal itching or discharge. This may mean you have a fungal infection called vaginal thrush. Sometimes taking AMILOXYN allows fungi to grow and the above symptoms occur.
• If you have to test your urine for sugar while you are taking AMILOXYN, ensure your doctor knows which type of test you use. AMILOXYN may affect the results of some of these tests.
• Remind any doctor, dentist or pharmacist you visit that you are taking AMILOXYN before starting any other medicines. Some medicines may affect the way other medicines work.

Things you should not do

• Do not stop taking AMILOXYN because you are feeling better, unless advised by your doctor. If you do not complete the full course prescribed by your doctor, all of the bacteria causing your infection may not be killed. These bacteria may continue to grow and multiply so that your infection may not clear completely or it may return.
• Do not give AMILOXYN to anyone else, even if their symptoms seem similar to yours.
• Do not take AMILOXYN to treat any other complaints unless your doctor says to.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how AMILOXYN affects you.

Generally, this medicine does not cause any problems with your ability to drive a car or operate machinery. However, as with many other medicines, AMILOXYN may cause dizziness or tiredness in some people.

Looking after your medicine

Keep your capsules in the original pack until it is time to take them. If you take the capsules out of its original pack it may not keep well.

Store in a cool dry place, away from moisture where the temperature stays below 25°C. Do not store it:

• in the bathroom or near a sink, or
• in the car or on window sills.

Keep it where young children cannot reach it.

Getting rid of any unwanted medicine

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

Do not take AMILOXYN after the expiry date.

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.

Less serious side effects

Serious side effects

Remember, you should tell your doctor or pharmacist as soon as possible if any of these, or any other unusual events or problems occur during or after treatment with AMILOXYN.

4.3 Contraindications

Amoxicillin is a penicillin and should not be given to patients with a history of hypersensitivity to beta-lactam antibiotics (e.g. penicillins, cephalosporins).

4.4 Special Warnings and Precautions for Use

Serious, and occasionally fatal, hypersensitivity reactions (including anaphylaxis, anaphylactoid and severe cutaneous reaction) have been reported in patients receiving beta-lactam antibiotics. Hypersensitivity reactions can also progress to Kounis syndrome, a serious allergic reaction that can result in myocardial infarction (see Section 4.8 Adverse Effects (Undesirable Effects)). These reactions are more likely to occur in individuals with a history of penicillin hypersensitivity and in atopic individuals. Before commencing therapy with any penicillin careful enquiry should be made concerning previous hypersensitivity reactions to penicillins, cephalosporins or other allergens. If an allergic reaction occurs, appropriate therapy should be instituted and amoxicillin therapy discontinued.
Serious anaphylactic reactions require immediate emergency treatment with adrenaline. Oxygen, intravenous steroids and airway management, including intubation should also be administered as indicated.
Drug induced enterocolitis syndrome (DIES) has been reported mainly in children receiving amoxicillin (see Section 4.8 Adverse Effects (Undesirable Effects)). DIES is an allergic reaction with the leading symptom of protracted vomiting (1-4 hours after administration of amoxicillin) in the absence of allergic skin or respiratory symptoms. Further symptoms could comprise abdominal pain, diarrhoea, hypotension, or leucocytosis with neutrophilia. There have been severe cases including progression to shock.
Although anaphylaxis is more frequent following parenteral therapy, it has occurred in patients on oral therapy. Before commencing therapy with any penicillin careful enquiry should be made concerning previous hypersensitivity reactions to penicillins, cephalosporins or other allergens. If an allergic reaction occurs, appropriate therapy should be instituted and amoxicillin therapy discontinued.
Serious anaphylactic reactions require immediate emergency treatment with adrenaline. Oxygen, intravenous steroids and airway management, including intubation, should also be administered as indicated.
Antibiotic associated pseudomembranous colitis has been reported with many antibiotics including amoxicillin. A toxin produced with Clostridium difficile appears to be the primary cause. The severity of the colitis may range from mild to life threatening. Clostridium difficile associated diarrhoea (CDAD) has been reported with the use of nearly all antibacterial agents and may range in severity from mild diarrhoea to fatal colitis. It is important to consider this diagnosis in patients who develop diarrhoea or colitis in association with antibiotic use (this may occur up to several weeks after cessation of antibiotic therapy). If prolonged or significant diarrhea occurs or the patient experiences abdominal cramps, treatment should be discontinued immediately, and the patient investigated further. Mild cases usually respond to drug discontinuation alone. However, in moderate to severe cases, appropriate therapy with a suitable oral antibiotic agent effective against Clostridium difficile should be considered. Fluids, electrolytes and protein replacement should be provided when indicated. Drugs which delay peristalsis, e.g. opiates and diphenoxylate with atropine (Lomotil) may prolong and/or worsen the condition and should not be used.
Adequate fluid intake and urinary output must be maintained in patients receiving high doses of amoxicillin.
Abnormal prolongation of prothrombin time (increased INR) has been reported rarely in patients receiving amoxicillin and oral anticoagulants. Appropriate monitoring should be undertaken when anticoagulants are prescribed concurrently. Adjustments in the dose of oral anticoagulants may be necessary to maintain the desired level of anticoagulation.
Amoxicillin should be avoided if infectious mononucleosis is suspected since the occurrence of a morbilliform rash has been associated with this condition following the use of amoxicillin.
Prolonged use may occasionally result in overgrowth of non-susceptible organisms.
As with any potent drug, periodic assessment of renal, hepatic and haematopoietic function should be made during prolonged therapy. The possibility of superinfections with mycotic or bacterial pathogens should be kept in mind during therapy. If superinfections occur (usually involving Aerobacter, Pseudomonas or Candida), the drug should be discontinued and/or appropriate therapy instituted.
Amoxicillin, an aminopenicillin, is not the treatment of choice in patients presenting with sore throat or pharyngitis because of the possibility that the underlying cause is infectious mononucleosis, in the presence of which there is a high incidence of rash if amoxicillin is used.
Amoxicillin should be given with caution to patients with lymphatic leukaemia since they are especially susceptible to ampicillin-induced skin rashes.
Following single dose therapy of acute lower urinary tract infections, the urine should be cultured. A positive culture may be evidence of a complicated or upper urinary tract infection and call for longer or larger course of therapy.
Adequate fluid intake and urinary output must be maintained in patients receiving high doses of amoxicillin.

Use in renal impairment.

Use in the elderly.

Paediatric use.

Effects on laboratory tests.

4.5 Interactions with Other Medicines and Other Forms of Interactions

Probenecid decreases the renal tubular secretion of amoxicillin. Concurrent use with amoxicillin may result in increased and prolonged blood levels of amoxicillin.
The concurrent administration of allopurinol and ampicillin increases substantially the incidence of rashes in patients receiving both drugs as compared to patients receiving ampicillin alone. It is not known whether this potentiation of ampicillin rashes is due to allopurinol or the hyperuricemia present in these patients. Similar reactions can be expected with amoxicillin.
In common with other antibiotics, amoxicillin may affect the gut flora, leading to lower oestrogen reabsorption and reduced efficacy of combined oral contraceptives.
In the literature there are rare cases of increased international normalised ratio in patients maintained on acenocoumarol or warfarin and prescribed a course of amoxicillin. If coadministration is necessary, the prothrombin time or international normalised ratio should be carefully monitored with the addition or withdrawal of amoxicillin.
Tetracyclines and other bacteriostatic drugs may interfere with the bactericidal effects of amoxicillin.

Methotrexate.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

4.7 Effects on Ability to Drive and Use Machines

The effects of this medicine on a person's ability to drive and use machines were not assessed as part of its registration.

4.8 Adverse Effects (Undesirable Effects)

As with other penicillins, it may be expected that untoward reactions will be essentially limited to sensitivity phenomena. They are more likely to occur in individuals who have previously demonstrated hypersensitivity to penicillins.
The following adverse reactions have been reported as associated with the use of amoxicillin.

Cardiac disorders.

Infections and infestations.

Gastrointestinal.

Skin and subcutaneous tissue disorders.

Hypersensitivity reactions.

Liver.

Haemic and lymphatic systems.

Renal and urinary tract disorders.

CNS effects.

Miscellaneous.

Reporting suspected adverse effects.

4.9 Overdose

Gastrointestinal effects such as nausea, vomiting and diarrhoea may be evident and symptoms of water/ electrolyte imbalance should be treated symptomatically. During the administration of high doses of amoxicillin, adequate fluid intake and urinary output must be maintained to minimize the possibility of amoxicillin crystalluria. Amoxicillin crystalluria, in some cases leading to renal failure, has been observed (see Section 4.4 Special Warnings and Precautions for Use).
Amoxicillin can be removed from the circulation by haemodialysis.
For information on the management of overdose, contact the Poisons Information Centre on 13 11 26 (Australia).
