The name of your medicine is Chemmart Azithromycin. It contains the active ingredient azithromycin (as azithromycin dihydrate).

How it works

Azithromycin is an antibiotic, which belongs to a group of medicines called azalides.

The azalides are a sub-class of a group of antibiotics called macrolides.

Azithromycin works by killing or stopping the growth of bacteria causing your infection.

Azithromycin will not work against viral infections such as colds or flu.

There is no evidence that this medicine is addictive.

How to take this medicine

Follow carefully all directions given to you by your doctor or pharmacist. Their instructions may be different to the information in this leaflet.

How much to take

Your doctor will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines. The usual dose to treat chlamydia is two 500 mg tablets taken as a single dose.

For other infections azithromycin is usually taken once a day. Sometimes the dose is taken once a week. Your doctor will decide the right dose for you.

Do not stop taking your medicine or change your dosage without first checking with your doctor.

How to take it

Swallow the tablets whole with liquid. This medicine may be taken with or without food.

If you are taking an antacid (e.g., Gastrogel, Mylanta), take it at least one hour before or two hours after this medicine dose.

This will avoid any possible effect of the antacid on the absorption of azithromycin.

When to take it

Take this medicine at the same time each day. Taking it at the same time each day will have the best effect and will also help you remember when to take it.

This medicine may be taken with or without food.

How long to take it for

Continue taking your medicine until you finish the pack or until your doctor recommends. Do not stop taking it because you are feeling better.

Make sure you have enough to last over weekends and holidays.

If you forget to take it

If you are taking your medicine for three days or longer and you miss a dose, take it as soon as you remember (within a 24- hour period), then continue as normal.

Do not take a double dose to make up for missed doses. This may increase the chance of you experiencing side effects.

If you are not sure what to do, check with your doctor or pharmacist.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints to help you remember.

If you take too much (overdose)

If you think that you or anyone else may have taken too much of this medicine, immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 in Australia) for advice. Alternatively go to the Accident and Emergency Department at your nearest hospital.

Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

While you are taking this medicine

Things you must do

If the symptoms of your infection do not improve within a few days, or if they become worse, tell your doctor.

If you get severe diarrhoea, tell your doctor, pharmacist or nurse immediately. Do this even if it occurs several weeks after you have stopped taking your medicine.

Diarrhoea may mean that you have a serious condition affecting your bowel. You may need urgent medical care. Do not take any diarrhoea medicine without first checking with your doctor.

If you get a sore, white mouth or tongue while taking, or soon after stopping azithromycin, tell your doctor. Also tell your doctor if you get vaginal itching or discharge.

This may mean you have a yeast infection called thrush. Sometimes the use of azithromycin allows yeast to grow and the above symptoms to occur. Azithromycin does not work against yeast.

Tell your doctor that you are taking this medicine if:

  • you are about to be started on any new medicine
  • you are pregnant or are planning to become pregnant
  • you are breastfeeding or are planning to breast-feed
  • you are about to have any blood tests
  • you are going to have surgery or an anaesthetic or are going into hospital.

Go to your doctor regularly for a check-up.

Tell any other doctors, dentists and pharmacists who are treating you that you take this medicine.

Things you must not do

Do not stop taking azithromycin or lower the dosage without checking with your doctor.

If you do not complete the full course prescribed by your doctor, all the organisms causing your infection may not be killed. These organisms may continue to grow and multiply so that your infection may not clear completely or may return.

Do not:

  • Give this medicine to anyone else, even if their symptoms seem similar to yours.
  • Take your medicine to treat any other condition unless your doctor or pharmacist tells you to.

Things to be careful of

Be careful when driving or operating machinery until you know how this medicine affects you.

Protect your skin when you are in the sun, especially between 10am and 3pm.

Some macrolide antibiotics may cause your skin to be more sensitive to sunlight than it is normally. Exposure to sunlight may cause a skin rash, itching, redness or severe sunburn.

If outdoors, wear protective clothing and use a 30+ sunscreen. If your skin does appear to be burning tell your doctor immediately.

Possible side effects

Tell your doctor as soon as possible if you do not feel well while you are taking azithromycin or if you have any questions or concerns.

Do not be alarmed by the following lists of side effects. You may not experience any of them. All medicines can have side effects. Sometimes they are serious but most of the time they are not.

Tell your doctor if you notice any of the following:

  • oral thrush - white furry, sore tongue and mouth
  • vaginal thrush - sore and itchy vagina and/or white discharge
  • nausea (feeling sick), loss of appetite, vomiting, stomach pain, indigestion, wind, constipation, diarrhoea
  • dizziness, headache, spinning sensation
  • tiredness, drowsiness, fatigue muscle or joint aches
  • hearing loss or ringing in the ears
  • altered taste and smell.

Tell your doctor immediately and before you take your next dose of azithromycin if you notice any of the following.

These are serious side effects. You may need urgent medical attention:

  • severe persistent diarrhoea (loose bowel motions)
  • fast or irregular heart beat
  • symptoms of sunburn such as redness, itching, swelling or blistering which may occur more quickly than normal
  • decreased feeling or sensitivity, especially in the skin
  • aggressive reaction, nervousness, agitation or anxiety

  • signs of frequent or worrying infections such as fever, severe chills, sore throat or mouth ulcers
  • blood in the urine or bowel motions
  • severe upper stomach pain, often with nausea and vomiting.

If you experience any of the following, stop taking your medicine and contact your doctor immediately or go to the Accident and Emergency department at your nearest hospital.

These are very serious side effects and are usually very rare. You may need urgent medical attention or hospitalisation.

  • blisters or ulcers on the skin, in the mouth or airways that may occur after a period of fever
  • diarrhoea, usually with blood and mucus, stomach pain and fever
  • yellowing of the eyes or skin, also called jaundice
  • chest pain
  • convulsions (fits).

Tell your doctor immediately if you notice any of the following side effects, particularly if they occur several weeks after stopping treatment with azithromycin:

  • severe stomach cramps
  • watery and severe diarrhoea, which may be bloody
  • fever, in combination with one or both of the above.

Azithromycin can cause some bacteria, which are normally present in the bowel and normally harmless to multiply and therefore cause the above symptoms. You may need urgent medical attention. However this side effect is rare.

Do not take any medicine for this diarrhoea without first checking with your doctor.

Tell your doctor if you notice anything else that is making you feel unwell.

Other side effects not listed above may also occur in some patients.
