13 reviews for Azithromycin (Zithromax)
Zithromax contains Azithromycin.
Azithromycin is an antibiotic from a group called macrolides. It stays in the body for a long time, so treatment is often just 3 to 5 days, or even a single dose for some infections.
It is used for chest, sinus, throat, ear and skin infections, and for some sexually transmitted infections such as chlamydia. It is a common choice for people who are allergic to penicillin.
What is it used for?
- Chest infections such as bronchitis and pneumonia
- Sinus, throat and ear infections
- Skin infections
- Chlamydia and some other sexually transmitted infections
How does it work?
Azithromycin stops bacteria from making the proteins they need to grow and multiply. This stops the infection spreading so your body can clear it.
This information is written in simple words to help you understand this product. It does not replace advice from your doctor or pharmacist.
Read these points before you start. If any of them apply to you, talk to your doctor or pharmacist first.
- Do not take it if you have ever had an allergic reaction to this antibiotic or to a similar one.
- Antibiotics only work on infections caused by bacteria. They do not help colds, flu or most sore throats, which are caused by viruses.
- Take the whole course your doctor gives you, even if you feel better after a few days. Stopping early can let the infection come back and make germs harder to treat in the future.
- Tell your doctor if you are pregnant, trying for a baby or breastfeeding.
- Never share your antibiotics or keep leftovers for another time.
- Tell your doctor if you have a heart rhythm problem (such as long QT syndrome), low potassium or magnesium, or take medicines that affect heart rhythm.
- Tell your doctor if you have liver problems or myasthenia gravis (a muscle weakness illness).
- Tell your doctor if you take a blood thinner such as warfarin, as your blood tests may need checking.
- Tell your doctor or pharmacist about every other medicine, vitamin or herbal product you use.
- Keep this product out of the reach and sight of children.
Like all medicines, Zithromax can cause side effects, but not everybody gets them.
Common side effects
- Feeling sick (nausea) or being sick
- Diarrhoea or loose stools
- Stomach ache or indigestion
These are usually mild and often get better as your body gets used to it. Tell your doctor if they bother you or do not go away.
Stop using it and get medical help straight away if you notice:
- Severe diarrhoea that is watery or has blood in it, even up to 2 months after you finish the medicine
- Signs of an allergic reaction, such as a rash, swelling of the face, lips or tongue, wheezing or trouble breathing
- A skin rash that blisters or peels, with fever and sore mouth or eyes
- A fast, pounding or uneven heartbeat, or fainting
- Yellowing of the skin or eyes, or dark urine
This is not a complete list. If you notice anything unusual, ask your doctor or pharmacist.
- Take it once a day, at the same time each day.
- Swallow the tablet with water. Tablets can be taken with or without food.
- A common course is 500 mg once a day for 3 days, or 500 mg on day 1 then 250 mg a day for 4 more days. For chlamydia, a single 1 g dose is often used.
- Keep taking it until the course is finished, even though it is short.
- If you use antacids with aluminium or magnesium, take them at least 2 hours apart from azithromycin.
If you miss a dose: Take it as soon as you remember. If it is nearly time for your next dose, skip the missed one and carry on as normal. Never take two doses at once to make up.
If you use too much: Contact your doctor, a poison control centre or your local emergency number straight away, even if you feel fine. Take the pack with you.
How to store it: Keep it in its original pack at room temperature (below 25°C / 77°F), away from heat, damp and direct sunlight. Do not use it after the expiry date.
- QWhy is the Zithromax course so short?
- A
Azithromycin stays in your body and keeps working for several days after your last tablet. That is why a 3 to 5 day course is usually enough.
- QCan I take Zithromax if I am allergic to penicillin?
- A
Yes, usually. Azithromycin is not related to penicillin and is often used for people with a penicillin allergy.
- QCan I drink alcohol with Zithromax?
- A
A small amount is unlikely to cause harm, but it is best to avoid alcohol while you are unwell.
- QWhen can I have sex after taking Zithromax for chlamydia?
- A
Wait 7 days after a single dose (or until the course is finished) and until your partner has also been treated, to avoid passing the infection back and forth.
