What is Azithromycin?

Azithromycin is an antibiotic used to treat lots of different types of bacterial infections. It’s sometimes prescribed for chlamydia when someone can’t take Doxycycline, which is the ‘first choice’ antibiotic treatment for chlamydia.

Azithromycin is usually taken for three days, and our clinician will tell you to take two tablets on the first day of treatment and one tablet on the second and third days.

Chlamydia is a very common infection. A recent WHO estimate put global chlamydia infections at 127 million . In Europe, it’s more prevalent among 18-24 year olds than any other age group.

Chlamydia is spread through unprotected sex, including oral sex.

Symptoms of chlamydia include:

  • pain when peeing;
  • in women, bleeding after sex;
  • in men, pain and discomfort in the testicles;
  • unusual discharge from the genitals or rectum.

It’s possible to have chlamydia without knowing because most people with it don’t get any symptoms. Estimates vary, but it’s thought that 61% of cases in women and 68% of cases in men are asymptomatic . This is one reason why men and women under 25 are advised to get tested each year if they regularly engage in unprotected sex.

You need to get tested before you can order treatment for chlamydia. You can get a test at a sexual health clinic and send the results to us, or you can order a test from us, collect your sample at home, and post this to our lab for analysis. If your test returns from our pathology lab with a positive result, we’ll advise you about the best course of treatment for you. If you’re not able to take Doxycycline, our clinicians might prescribe Azithromycin.

If your partner has a positive test result, you can order a test + treat kit and start taking the medication before your test result comes back from the lab.

Three weeks after finishing your treatment, it’s recommended to check that treatment has been successful by taking a test. If you’ve already got a positive result, you’ve got the option to order treatment and a test kit together as a ‘test of cure’ from us.

How does Azithromycin work?

Azithromycin belongs to a group of medicines called macrolide antibiotics. Chlamydia is caused by a type of bacteria called C. Trachomatis. The antibiotic attacks the bacteria that causes infection and weakens it before eventually killing it. It does this by stopping the bacterial cell from making a protein which helps it to grow. Without the protein, the bacteria can’t multiply and the infection clears up.

What doses of Azithromycin are there?

Azithromycin is made in two different dose sizes: 500mg and 250mg. When it’s used to treat chlamydia, the 500mg dose is used.

You usually take Azithromycin for three days when taking it for chlamydia. You’ll take two 500mg tablets on day one and one 500mg tablets on days two and three.

There’s a branded version of the drug called Zithromax, from Pfizer. Azithromycin is the generic version of it.

How to take Azithromycin for chlamydia

It’s important to take your medicine as directed so that it works properly. You should always complete the full course of treatment.

You’ll take Azithromycin tablets for three days:

  • Two tablets on day one.
  • One tablet on days two and three.

You should:

  • Take your tablet(s) at the same time each day
  • Take your tablets with water
  • Not have sex for at least seven days after your course of treatment has ended to ensure you don’t put someone else at risk of becoming infected.

How long does it take Azithromycin to work?

It takes around seven days for Azithromycin to kill chlamydia. Even though the tablets are only taken for three days, it’s important to remember that you could still be infectious after your treatment has finished. You shouldn’t have sex for at least seven days after finishing treatment so that you don’t risk passing the infection on to someone else .

What should I do if I make a mistake when taking Azithromycin?

If you make a mistake when taking Azithromycin you should let us know, so we can advise you on what to do next. You may need to restart your course of treatment. It’s important you don’t have sex until you’ve completed a full course of treatment because you could risk passing the infection on to your partner.

FAQ: Azithromycin Tablets

Have something specific you want to know? Search our info below, or ask our experts a question if you can’t find what you’re looking for.

How is Azithromycin different to other treatments for chlamydia?

Answer:
Azithromycin is an effective antibiotic used to treat chlamydia, but Doxycycline is the most common treatment because it’s slightly more effective. If you can’t take Doxycycline (for example, if you’re allergic to anything in it) you’ll be prescribed Azithomycin.

Both tablets are antibiotics that attack and kill chlamydia. Doxycycline is taken over a longer period of time than Azithomycin and comes in a different dosage size.

Do I need to have a positive test result to order Azithromycin?

Answer:
If your sexual partner has tested positive for chlamydia, you don’t need a positive test result for yourself before you can start taking Azithromycin. It’s recommended you collect a sample for testing, but don’t wait for the result to come back before starting the treatment.

Otherwise, to be prescribed Azithromycin you’ll need a positive chlamydia test result. You can provide this test result before ordering, or you can order a test first and then we’ll advise you on treatment if your test is positive.

How effective is Azithromycin at treating chlamydia?

Answer:
Azithromycin is an effective treatment for chlamydia and has a success rate of over 90%, according to a study published in the New England Journal . However, the more we use antibiotics, the less effective they become at killing infections because the bacteria in them adapt and become resistant to the antibiotic. It’s important to take your course of treatment exactly as your clinician tells you to so that you reduce the risk of antibiotic resistance.

Do I need a prescription for Azithromycin?

Answer:
You’ll need a prescription for Azithromycin because our clinician will need to check that the infection you’ve got is chlamydia. If you’ve got a different type of infection, a different antibiotic might be more effective.

If your partner hasn’t tested positive, you'll need a positive chlamydia test result to order Azithromycin. You can provide a test result from somewhere else, or you can use our testing service to get your result before starting your course of treatment.

If your partner has a positive test result, you can order our test + treat kit and start your treatment whilst you wait for your test result.
