What is in this leaflet
This leaflet answers some common questions about azithromycin. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you using this medicine against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.

What this medicine is used for
Azithromycin is used to treat infections in different parts of the body caused by bacteria, such as chlamydia. Azithromycin belongs to a group of medicines called macrolide antibiotics.
How it works
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.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.
This medicine is not addictive.
There is not enough information to recommend the use of azithromycin tablets in children.

How to take this medicine
Follow all directions given to you by your doctor and pharmacist carefully. They may differ to the information contained in this leaflet.
If you do not understand the instructions on the pack, ask your doctor or pharmacist for help.
How much to take
Your doctor will tell you how much of this medicine you should take, depending 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.
How to take it
Swallow the tablets whole with liquid.
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 about the same time each day. Taking it at the same time each day will have the best effect. It 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 says to. 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.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at your nearest hospital if you think that you or anyone else may have taken too much of this medicine. 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 you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking this medicine.
Tell any other doctors, dentists and pharmacists who are treating you that you take this medicine.
If you become pregnant while taking this medicine, tell your doctor immediately.
Tell your doctor if the symptoms of your infection do not improve within a few days, or if they become worse.
If you get severe diarrhoea, tell your doctor 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.
Keep all of your doctor's appointments so that your progress can be checked. Your doctor may want to check your progress to make sure the medicine is working and to prevent unwanted side effects.
Things you must not do
Do not give this medicine to anyone else, even if they have the same condition as you.
Do not take your medicine to treat any other complaint unless your doctor tells you to. Do not stop taking your medicine, or change the dosage, without first checking with your doctor. If you do not complete the full course, 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.
Things to be careful of
Be careful 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.
Tell your doctor and pharmacist as soon as possible if you do not feel well while you are taking azithromycin.
This medicine helps most people with infections, 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 or pharmacist to answer any questions you may have.
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

The above list includes the more common side effects of your medicine.
Tell your doctor as soon as possible and before you take your next dose of azithromycin if you notice any of the following:
- 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
- bleeding or bruising more easily than normal, reddish or purplish blotches under the skin
- signs of frequent or worrying infections such as fever, severe chills, sore throat or mouth ulcers
- blood in the urine or bowel motions

The above list includes serious side effects and you may need urgent medical attention.
If any of the following happen, stop taking your medicine and contact your doctor immediately or go to Accident and Emergency at your nearest hospital:
- shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue, throat or other parts of the body; rash, itching or hives on the skin (signs of an allergic reaction)
- 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)
The above list includes very serious side effects and are usually very rare. You may need urgent medical attention or hospitalisation.
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. 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.
