Azithromycin is a wide spectrum antibiotic that can be used in the treatment of a number of sexually transmitted infections, which could include non-specific urethritis (NSU), chlamydia, gonorrhoea, mycoplasma and ureaplasma. Azithromycin 500mg is highly effective, and because it has the ability to stay in a person’s system for longer, it’s often recommended that it’s taken in a single dose, instead of over the course of a week.

This treatment is available to order from Please be aware that this is a prescription medication, which is why we ask all patients to complete a confidential consultation form when they buy Azithromycin 500mg. This form is only intended for our doctor to make sure that you qualify for a prescription and will be treated with the strictest confidence.

What conditions can it treat?

Azithromycin 500mg can be used to treat and cure gonorrhoea, chlamydia, mycoplasma genitalium, ureaplasma urealyticum and non-specific urethritis. However, it is also used to treat other bacterial infections that affect other parts of the body, including Lyme disease, typhoid, middle ear infections, pneumonia, bronchitis, sinusitis and tonsillitis.

How do Azithromycin tablets work?

Azithromycin tablets are effective because they attack the bacteria directly, affecting its ability to produce proteins that are important for it to increase in numbers. If bacteria are unable to reproduce, it’s more vulnerable to attacks by the immune system, but they are also simply more likely to die off naturally.

How do you use it?

In order to effectively treat a mycoplasma, gonorrhoea, ureaplasma, NSU or chlamydia infection a single high dose of Azithromycin tablets is usually sufficient. Doses are as follows:

  • Chlamydia and ureaplasma requires a single 1500mg dose (Azithromycin 250mg x 6)
  • Gonorrhoea requires a single 1000mg dose in conjunction with a high dose of Cefixime (Gonorrhoea Treatment Pack)
  • Non-specific urethritis and mycoplasma genitalium can both normally be cured with a high, 2000mg dose

Can it cause side effects?

Just like any prescription medication, there is a risk of side effects if you take Azithromycin 500mg, but this risk isn’t high. Some of the most common side effects include mild nausea, diarrhoea, vomiting, constipation, stomach upsets or pain, dizziness, headaches,tiredness, vaginal itching, vaginal discharge, itchy skin or rashes.

You should mention during your doctors consultation if you have any existing health conditions, as this may mean that you need to take an adjusted dose to minimise the risk of side effects.
