What Zithromax is used for

Zithromax is used to treat infections in different parts of the body caused by bacteria.
It is commonly used to treat Chlamydia. Zithromax is also used to prevent infections by a bacterium called Mycobacterium Avium-intracellulare Complex (MAC) in some people.
Zithromax 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.
Zithromax works by killing or stopping the growth of bacteria causing your infection.
Zithromax will not work against viral infections such as colds or flu.
Ask your doctor if you have any questions about why Zithromax has been prescribed for you.
Your doctor may have prescribed it for another reason.

Your doctor or pharmacist has more information on medicines to be careful with or to avoid while taking Zithromax.
Talk to your doctor about the need for additional contraception while taking Zithromax.
Some antibiotics may decrease the effectiveness of some birth control pills, although this has not been shown with Zithromax.

How to take Zithromax

Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from 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

The dose will depend on your infection.
The usual dose to treat Chlamydia is two 500 mg tablets taken as a single dose.
For other infections Zithromax is usually taken once a day. Sometimes the dose is taken once a week. Your doctor will decide the right dose for you.
The dose for your child will depend on his or her body weight. Zithromax oral suspension is for use by children.
Your pharmacist will explain how to use it if you are not sure.

How to take it

Tablets:
Swallow the tablets whole with liquid.
Oral Suspension:
Shake the bottle well before use and use the measuring syringe supplied.
Zithromax 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 your Zithromax dose.
This will avoid any possible effect of the antacid on the absorption of Zithromax.

How long to take it

Continue taking Zithromax until you finish the pack or bottle or until your doctor recommends.
Do not stop taking it because you are feeling better.
If you do not complete the full course prescribed by your doctor, the infection may not clear completely or your symptoms may return.
If you are not sure how long you should be taking Zithromax, check with your doctor.

If you forget to take it

If you are taking Zithromax 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 try to make up for missed doses by taking more than one dose at a time.
If you are not sure what to do, check with your doctor or pharmacist.
If you have trouble remembering to take your Zithromax, ask your pharmacist for some hints.

If you take too much (Overdose)

Immediately telephone your doctor if you think that you or anyone else may have taken too much Zithromax.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you take too many tablets or too much oral suspension, you may get an upset stomach, diarrhoea or skin rashes.

While you are using Zithromax

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 Zithromax 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.
If you get a sore, white mouth or tongue while taking, or soon after stopping Zithromax, 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 Zithromax allows yeast to grow and the above symptoms to occur. Zithromax does not work against yeast.
If you become pregnant while taking Zithromax, tell your doctor.
Tell your doctor immediately if during treatment with Zithromax your baby develops irritability with feeding or starts vomiting.
This may be a sign of a stomach disorder in the infant.
If you are about to start any new medicines, tell your doctor and pharmacist that you are taking Zithromax.
Tell any other doctors, dentists and pharmacists who are treating you that you are taking Zithromax.

Things you must not do

Do not stop taking Zithromax 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 Zithromax to anyone else, even if they have the same condition as you.
Do not use Zithromax to treat any other medical complaints unless your doctor tells you to.

Things to be careful of

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.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Zithromax.
Like other medicines, Zithromax 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 or pharmacist to answer any questions you may have.
Do not be alarmed by the following list of side effects. You may not experience any of them.

While taking it

Tell your doctor or pharmacist if you notice any of the following and they worry you:
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
rash
hearing loss or ringing in the ears
altered taste and smell.
These side effects are usually mild.
See your doctor immediately and before you take your next dose of Zithromax 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
hives, itching or skin rash
widespread body rash, fever and swollen lymph nodes
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
dark urine or blood in the urine or bowel motions
severe upper stomach pain, often with nausea and vomiting.
These are serious side effects. You may need urgent medical attention. Serious side effects are rare.
If any of the following happen, stop taking Zithromax and tell your doctor immediately or go to casualty at your nearest hospital:
sudden signs of allergy such as rash, itching or hives on the skin, swelling of the face, lips, tongue or other parts of the body, shortness of breath, wheezing or trouble breathing
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
fainting
convulsions (fits)
These are very serious side effects. You may need urgent medical attention or hospitalisation. 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 Zithromax:
severe stomach cramps
watery and severe diarrhoea, which may be bloody
fever, in combination with one or both of the above.
Zithromax 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. Some of these side effects (for example certain liver conditions, and blood abnormalities) can only be found when your doctor does tests from time to time to check your progress.
Do not be alarmed at this list of possible side effects.
You may not experience any of them

After using Zithromax

Storage

Keep Zithromax in its original packaging until it is time to use it.
