Zithromax (azithromycin)

What is Zithromax?

Azithromycin is sold under the brand name Zithromax. Azithromycin is an antibiotic used to treat a number of infections caused by bacteria, included the sexually transmitted infection Chlamydia. It can also be used to treat Gonorrhoea but this would not be the front line choice for this particular infection (as a mono-therapy). Azithromycin is a broad-spectrum antibiotic, meaning that it is prescribed as treatment for a wide range of infections.

It is sometimes sold under its generic name, azithromycin, and is also available in the brand names Clamelle and Zithromax.

How does Zithromax (azithromycin) work?

Azithromycin works by blocking the actions of certain proteins that bacteria need to thrive. Without the proteins, the bacteria are prevented from growing, replicating and multiplying. With the spread of the infection curbed, the remaining bacteria are killed off by the body's immune system or die of their own accord.

How is Azithromycin used to treat Chlamydia?

If you are prescribed Zithromax (azithromycin) to treat Chlamydia, then it is usually given in a single dose of four capsules. Although the medication will start working straight away, it will take 7 days to clear the Chlamydia infection so you must not have sex in this period.

What else is Zithromax used to treat?

Zithromax (azithromycin) is used as part of the treatment for Gonorrhoea but not as a mono-therapy. This medication can also be used to treat Ureaplasma and Mycoplasma Genitalium. For these infections, we recommend a 5 day course rather than a single 1000 mg dose. Azithromycin is also used to treat non-specific urethritis (NSU).

Can I get my partner treated with Zithromax?

If you have tested positive for an STD/STI and you have been prescribed Azithromycin then you need to make sure that your partner also gets treated, otherwise you risk passing the infection back and forth. Once you've both been treated, you should avoid sex for 7 days after treatment.

Azithromycin is very effective against Chlamydia so it is not necessary to get retested after treatment. Other infections sometimes require a retest. If you are getting retested, you should wait at least 3 weeks after you have completed the treatment. Some testing techniques will require you to wait longer for a retest as there is the possibility of a false positive result after treatment.

We recommend The STI Clinic for a fast and accurate sexual health check.

Are there any side effects of Zithromax (azithromycin)?

The most common side effects of this antibiotic are diarrhoea, nausea, vomiting or stomach pains.

Sometimes broad-spectrum antibiotics can cause the bowel to become inflamed. If you are taking this antibiotic and find that you are experiencing severe or persistent diarrhoea, then you need to see your doctor immediately.

Can everyone take Zithromax (azithromycin)?

This antibiotic should not be taken if you are allergic to the ingredients or similar antibiotics, if you have severe liver disease or if you are pregnant, unless your doctor considers it to be absolutely necessary. It is also not recommended for use during breast-feeding. You should not take Zithromax with certain antacids along with some other medications. You should make a full disclosure to our doctor to ensure that Zithromax is an appropriate medication for you.

If you or a sexual partner has tested positive for a sexually transmitted infection but you do not have access to treatment then we may be able to help. Please click on the free consultation icon to start completing your consultation form, which will be reviewed by one of our doctors.
