What AZITH is used for

AZITH is an antibiotic which contains azithromycin as the active ingredient. Azithromycin belongs to a group of medicines called azalides which are a sub-class of a group of antibiotics called macrolides.

AZITH is used to treat pneumonia, a lung infection caused by certain bacteria such as Legionella pneumophila.

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

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

Ask your doctor if you have any questions about why AZITH has been prescribed for you. Your doctor may have prescribed it for another purpose.

This medicine is available only with a doctor's prescription.

There is no evidence that it is addictive.

If you are not sure whether you should be given AZITH, talk to your doctor.

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.

Tell your doctor if you are pregnant or plan to become pregnant. Your doctor will discuss the possible risks and benefits of taking this medicine during pregnancy.

Tell your doctor if you have or have had any of the following medical conditions:

  • diabetes mellitus (sugar diabetes)
  • kidney problems
  • liver problems
  • heart problems.

If you have not told your doctor about any of the above, tell them before you start being given AZITH.

Taking other medicines

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

Some medicines may interfere with AZITH. These include:

  • antacids, a medicine used to treat
  • indigestion
  • coumarin-type oral anticoagulants, a medicine used to prevent blood clots
  • cyclosporine, a medicine used in transplant patients
  • digoxin, a medicine used to treat abnormal heart rhythm e.g. atrial fibrillation
  • ergot derivatives such as ergotamine, which is used to treat migraines
  • terfenadine or astemizole, medicines used to treat allergies and hayfever
  • zidovudine, a medicine used to treat patients with AIDS.

These medicines may be affected by AZITH or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines. Your doctor or pharmacist has more information on medicines to be careful with or avoid while having this medicine.

Talk to your doctor about the need for additional contraception while taking AZITH. Some antibiotics may decrease the effectiveness of some birth control pills, although this has not been shown with AZITH.

How it is given

AZITH is a sterile powder which is dissolved in sterile water for injections and then diluted before use. It is given as a slow injection into a vein, known as a continuous infusion or a 'drip'.

It will take at least 60 minutes for the solution containing your dose of AZITH to be infused into your vein.

Your doctor or nurse will prepare the infusion for you.

How much to be given

Your doctor will decide the dose of AZITH you will be given by infusion and for how long.

You may then be given oral azithromycin to take in order to complete a 7 to 10 day course of antibiotic therapy.

Things to be aware of

If you are taking an antacid (e.g. Gastrogel, Mylanta), take it at least one hour before or one hour after your azithromycin dose. This will avoid any possible effect of the antacid on the absorption of your medicine.

If you are given too much (overdose)

As AZITH is given under the close supervision of your doctor, it is unlikely that you will receive too much.

However, if you experience any side effects after being given AZITH, tell your doctor immediately.

While you are using it

Things you must do

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

Tell your doctor, pharmacist or nurse immediately if you get severe diarrhoea. Do this even if it occurs several weeks after AZITH has been stopped. 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.

Tell your doctor if you get a sore, white mouth or tongue while taking, or soon after stopping AZITH.

Tell your doctor if you get vaginal itching or discharge. This may mean you have a yeast infection called thrush. Sometimes the use of AZITH allows yeast to grow and the above symptoms to occur. AZITH does not work against yeast.

Tell your doctor if you become pregnant while taking AZITH.

Tell all other doctors, dentists and pharmacists who are treating you that you are taking AZITH, especially if you are being started on any new medicines.

Things to be careful of

Protect your skin when you are in the sun, especially between 10 am and 3 pm. If outdoors, wear protective clothing and use a 30+ sunscreen. If your skin does appear to be burning tell your doctor immediately. Some macrolide antibiotics like AZITH may cause skin to be more sensitive to sunlight than it is normally. Exposure to sunlight may cause a skin rash, itching, redness or severe sunburn.

Things you must not do

Do not stop taking your medicine 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 your medicine to anyone else even if they have the same condition as you.

Do not use your medicine to treat any other medical complaints unless your doctor tells you to.

Side effects

Tell your doctor, nurse or pharmacist as soon as possible if you do not feel well while you are having AZITH. Like other medicines, AZITH can cause some side effects. If they occur, most are likely to be minor and temporary. However, some may be serious and need medical attention.

Ask your doctor to answer any questions you may have.

Tell your doctor if you notice any of the following side effects and they worry you:

  • pain at the site of infusion and pain during infusion
  • 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, loose bowel motions
  • rash
  • dizziness, headache, spinning sensation
  • tiredness, drowsiness, fatigue
  • muscle or joint aches
  • hearing loss or ringing in the ears
  • altered taste and smell
  • inability to feel or touch as normal.

Tell your doctor immediately if you notice any of the following:

  • aggressive reaction, nervousness and anxiety
  • severe persistent diarrhoea
  • fast or irregular heartbeat, chest pain
  • jaundice, yellowing of the skin and eyes
  • fainting
  • difficulty breathing
  • swelling of the face, lips or tongue
  • hives, itching or skin rash
  • symptoms of sunburn such as redness, itching, swelling or blistering which may occur more quickly than normal

  • bleeding or bruising more easily than normal
  • blood in the urine or bowel motions
  • little or no urine

  • severe upper stomach pain, often with nausea and vomiting.

The above list includes serious side effects which may require medical attention. These side effects are rare.

After finishing it

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

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

AZITH 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 people.

Do not be alarmed by this list of side effects. You may not experience any of them.
