What is Azithromycin?
Azithromycin is a medicine that belongs to a group of antibiotics called macrolides. Azithromycin is used to treat bacterial infections caused by microorganisms, such as bacteria. These infections can include chest, throat or nasal infections, along with ear, skin and sexually transmitted infections.
Azithromycin is used for the treatment of chlamydia. This is usually contracted through unprotected sex with someone who has chlamydia.
Chlamydia doesn't always show symptoms immediately, and some people may have more symptoms than others. Symptoms in women can include bleeding between periods, pain in the lower abdomen and a burning pain when passing urine. In men, symptoms may include a discharge from the penis and a burning feeling while passing urine.
To reduce the risk of contracting a sexually transmitted infection, it is important to protect yourself by using barrier methods of contraception, like using a condom for all anal, oral and vaginal sex. Oral contraceptives do not protect you from sexually transmitted diseases.
Azithromycin is a prescription only medication. You cannot buy it without a prescription. However, we can prescribe it to you following an online consultation. Contact us to find out more.

How it works
Azithromycin works by stopping the bacteria causing the chlamydia infection from developing and spreading by interfering with the process of protein synthesis.
As bacteria require certain proteins in order to multiply and grow, interfering with their ability to do this slows their growth and damages the bacterial cells. The immune system is better able to attack the weakened bacteria to clear the infection.

Azithromycin is not the first line treatment for chlamydia as there is evidence that an increasing number of cases of chlamydia have shown resistance to this antibiotic. Azithromycin may still be used for patients who cannot tolerate the first line treatment, which is doxycycline.
