How does Azithromycin work?

Azithromycin is an antibiotic that is used to treat a number of different bacterial infections. When these bacterial infections spread, the bacteria produce proteins that allow them to reproduce. The rate of reproduction is so fast that the body’s immune system is unable to keep up. Azithromycin prevents the bacteria from producing the protein they need to reproduce, which effectively stops the infection in its track. This gives the immune system time to kill the remaining bacterial cells.

What are the benefits of Azithromycin?

Azithromycin offers a fast and effective way to treat a wide range of bacterial infections. Unlike some other antibiotics that require lengthy treatment courses, this medication can clear STI’s like chlamydia in a single dose. Treating these infections in this way also significantly reduces the risk of side effects occurring.

How do you use Azithromycin?

For most genital infections, the treatment course of Azithromycin is 2 x 500mg tablets that are taken together in a single 1000mg dosage. This single dose treatment is sufficient to clear chlamydia, ureaplasma urealyticum, mycoplasma genitalium and non-specific urethritis.

The treatment for gonorrhoea is a little different as the 2 x 500mg Azithromycin tablets are taken in conjunction with 2 X 200mg Cefixime tablets. Again, these tablets are all taken together (or one after another if this is difficult). This single dose treatment option is sufficient to clear a gonorrhoea infection.
