Patient advice regarding Azithromycin for treatment of Chlamydia infection.
How it works
Azithromycin is an antibiotic used to treat various infections, including chlamydia. It kills the chlamydia bacteria.
Alternative treatments: Usually chlamydia is treated with another antibiotic, called doxycycline. Reasons you are being treated with azithromycin include that you are pregnant; at risk of pregnancy; breastfeeding; allergic to doxycycline; have a medical condition or take a medicine that is not safe with doxycycline.
Effectiveness
When taken correctly, Azithromycin will kill the bacteria causing the infection.
You should avoid sexual intercourse completely until treatment has been completed, and until any partner(s) has completed their treatment. This means avoiding all sex, even with condoms, even genital to genital skin contact or oral sex. This is because of the risk of being infected again.
It is important to inform any partners so that they can get tested and treated. This will stop you getting re-infected. Please let our health advisors know if you would prefer us to contact partners anonymously. Partners can order via GP or pharmacies, or online if under 25 years old.
It is not a vaccination. You can be re-infected with chlamydia. Using condoms every time you have sex (oral, vaginal, anal) is the best way to make sure you do not get STIs. Re-test every year or whenever you have a new partner
Please book an appointment at LSH if you have fever, lower abdominal pain (women only), or testicle pain. This is because you may need a different course of antibiotics.
If you have ongoing symptoms, then please make an appointment at LSH for review
If you are pregnant, then it is important to do a repeat test in 6 weeks to make sure the chlamydia is gone and that there is no risk to the baby.
