What is Azithromycin?

Azithromycin (also branded as Zithromax) is an STI medication that functions as an antibiotic, specifically targeting the different types of bacteria responsible for infections, chlamydia, ureaplasma urealyticum, and gonorrhoea (when combined with Cefixime).

One of the main benefits of Azithromycin is this medication's ability to be able to cure most infections in a single high dose. Taking it in a single dose also means that it's less likely to cause lasting side effects. Azithromycin is also able to treat more than one non-gonococcal infection at a time, which is extremely beneficial, as some STIs tend to flourish alongside others.

Short facts about Azithromycin
How to take

You take Azithromycin tablets most often in a high single dose, which minimises side effects. Specific dosages vary depending on condition.

How it works

It targets the bacteria that causes the STI by attacking it directly, stopping the production of proteins that are essential for the bacteria's survival.


Azithromycin is one of the most widely prescribed antibiotics for various STIs, and provides a cure rate of 96% when observed with Chlamydia patients.


Azithromycin is available to buy in both 250mg dosage and 500mg dosage, however, you may take two doses to create a 1000mg quantity, which is often required.

Side effects

Due to the single dose, side effects are rare. However, some that are reported include diarrhoea, nausea and loss of appetite.

How does Azithromycin work?

Azithromycin (Zithromax) attacks the bacterial cells responsible for infections directly, influencing their ability to produce proteins that are integral to their survival. If the bacterial cells aren't able to keep themselves alive, they can't produce, which causes them to die off, stopping the infection.

How to take Azithromycin?

The way you use Azithromycin antibiotic tablets varies depending on your specific condition. You can find these different ways detailed below.

  • To treat penile/vaginal chlamydia - Azithromycin should be taken in a single 500mg x 2 dose. However, Doxycycline is a more effective treatment option for anorectal chlamydia. It's advised that you buy both treatments if you are experiencing symptoms of both.
  • To treat ureaplasma urealyticum - a single 1000mg dose is suitable.
  • To treat non-specific urethritis or mycoplasma genitalium - a single 500mg x 2 dose is required.
  • To treat a gonorrhoea - a single 1000mg dose (2 doses of 500mg tablets) of Azithromycin should be combined with a treatment of Cefixime for successful treatment.

Please bear in mind that you'll need to wait seven days after having treatment before having sex again. Also, consuming alcohol will not prevent Azithromycin from killing the bacteria causing your infection.


Varying dosages of 250mg and 500mg (which can be combined to create the 1000mg dosage when necessary) are available to buy online from OnlineClinic, depending on the condition you are suffering from. For further information about which dosage is most suitable, please see the How to use section above. All these dosages have been specifically designed by the manufacturer to be effective while minimising side effects.

Side effects and precautions

Side effects of Azithromycin tablets aren't usual, but if they do occur, they are normally mild and don't last long, because treatment is so short. Common side effects can potentially include diarrhoea, nausea, vomiting and abdominal pain, fatigue and loss of appetite.

Contact a doctor straight away if you experience any more serious side effects, if these effects persist, or if you start developing an allergic reaction.

Azithromycin is generally well tolerated, but as with all prescription medications, it may not be right for everybody to take. So it's important that you mention to your doctor if you have any existing medical conditions or if you are currently taking any other medications that may interact badly.

Some of the precautions you should be aware of before you buy Azithromycin tablets include:

  • People who have had jaundice or liver problems caused by taking azithromycin should consult a doctor.
  • People who are allergic to similar drugs such as clarithromycin, erythromycin, or telithromycin should consult a doctor.
  • Azithromycin may not be safe for you, if you have liver disease; kidney disease; myasthenia gravis; or a heart rhythm disorder.
  • It is advised to use caution when taking Azithromycin whilst also using blood thinners.
