Treating chlamydia with azithromycin

Chlamydia is a sexually transmitted infection (STI) that is passed on through unprotected sex. It is one of the most common STIs in the UK, with young people aged between 15-24 most likely to be diagnosed with the infection. (, 2016)

The first line treatment for chlamydia is doxycycline 100mg. However, there are situations where you may be prescribed azithromycin to treat chlamydia. Your doctor or prescriber will be able to advise you further.

One of the biggest issues surrounding chlamydia is that many people do not notice any symptoms and quite simply don’t know they have it until complications, such as pelvic inflammatory disease (PID), are diagnosed.

If you are sexually active it is recommended that you get tested every year or when you change sexual partners. If you’re not sure whether you have chlamydia and want to get tested, you can either go to your GP or your local sexual health clinic, or, if you don’t want to visit them, you can use a chlamydia home testing kit.

If you find you have chlamydia, there’s no need to panic, as the infection has a 95% treatment success rate and can usually be treated with oral antibiotics, such as Azithromycin.

How does azithromycin chlamydia treatment work?

Azithromycin is an antibiotic used to treat chlamydia and other infections, such as chest infections, and Lyme disease. It works by stopping the offending bacteria from producing the proteins they need to survive; it is only effective against bacterial infections and does not work against viruses.

Azithromycin is one of the most common treatments for chlamydia in the UK; another treatment often used is Doxycycline.

Azithromycin dose for chlamydia

For most, chlamydia infection symptoms should start to disappear after a few days when taking Azithromycin. If your symptoms stop or, as is common with chlamydia, you don’t have any symptoms at all – it is important that you finish your course of Azithromycin. This will give the medication the best chance of dealing with the infection. If you do stop your treatment early the infection may return.

Can Everyone Use the Chlamydia Treatment Azithromycin?

Treating chlamydia with Azithromycin is usually effective, though there have been some rare cases where the infection has shown resistance to the medication.

Azithromycin can be taken by most healthy adults, but it is not recommended if you are pregnant, breastfeeding or:

  • Have had an allergic reaction to Azithromycin in the past
  • Have liver, kidney or heart problems
  • Have irregular heartbeat
  • Have had diarrhoea when you’ve previously taken antibiotics
  • Have the muscle-weakening illness myasthenia gravis
  • Have diabetes
  • Are taking certain medications, such as warfarin, antacids, ciclosporin, tacrolimus, ergotamine, dihydroergotamine, colchicine, digoxin, rifabutin and nelfinavir

When you place your order, you will need to fill out a short questionnaire, which will be reviewed by our GPhC registered prescribers.

Chlamydia tablets, such as Azithromycin, are safe for most people, however, like with most medication there may be some side effects which can include:

  • Feeling sick or being sick
  • Diarrhoea
  • Loss of appetite
  • Headaches, feeling dizzy or tiredness
  • Changes to your sense of taste

A full list of the side-effects of Azithromycin can be found on the product page.

Azithromycin chlamydia treatment: how long does it take to work?

The amount of Azithromycin needed to effectively treat chlamydia will depend on the severity of the infection; typically, you will need to take Azithromycin for three to 10 days. However, chlamydia remains infectious for up to a week after successful antibiotic treatment. It is recommended that you do not have any sexual contact with anyone for a week after finishing treatment.
