Chlamydia is one of the most common sexually transmitted infections (STIs). It's passed on through unprotected sex (sex without a condom) and is particularly common in sexually active teenagers and young adults. 

Most people with chlamydia do not notice any symptoms and do not know they have it.

If You Do Develop Symptoms, You May Experience:

  • pain when peeing
  • unusual discharge from the vagina, penis or bottom
  • in women, pain in the tummy, bleeding after sex and bleeding between periods
  • in men, pain and swelling in the testicles

If you think you're at risk of having a sexually transmitted infection (STI) or have any symptoms of chlamydia, visit a GP, community contraceptive service or local genitourinary medicine (GUM) clinic to get tested.

A good self care guide and information for chlamydia is available on the NHS website.

When Will I Feel Better?

What If I Do Not Get Better?

Will It Stop My Contraception Working?

Azithromycin is generally thought to be OK to take during pregnancy if you have an infection that needs treatment. However, other antibiotics may be more suitable for you, depending on your type of infection. Talk to your doctor about taking azithromycin as it should only be taken if the benefits outweigh the possible risks.

Can I Drive While Taking Azithromycin?

Azithromycin Tablets may cause dizziness and seizures so make sure you are not affected before driving or operating machinery.
