Azithromycin is an antibiotic used in the treatment of various infections, including chlamydia. Azithromycin is a type of antibiotic known as a macrolide. It works by inhibiting the growth and reproduction of bacteria and causing them to die off.
Azithromycin cures chlamydia in 97% of cases. If your symptoms are still present after you have completed your treatment, you should see your doctor and you may need to be re-tested. As with all antibiotics, bacteria can become resistant, which may mean the treatment might not work as well. You may need a different antibiotic if the first treatment has not cleared the infection.
