Chlamydia is one of the most common sexually transmitted infections (STIs) in the UK. If you or a partner have tested positive but are not showing symptoms, we can prescribe treatment, providing it’s suitable for you. It’s important to get treated because if left untreated it can lead to long-term health problems. If you’ve got chlamydia symptoms, you should visit your GP or health clinic. It’s best to get tested for a range of STIs if you’ve been told you need chlamydia treatment.
