Azithromycin is a generic antibiotic, recommended for many cases of bacterial infection, including chlamydia and cellulitis.

Azithromycin is an antibiotic medication containing an active ingredient of the same name and is prescribed to treat bacterial infections. It was first marketed in the 1990s by Pfizer under the name Zithromax.

Chlamydia is the most common STI in UK, and it is estimated that approximately 100,000 people are infected each year. This disease results from a bacterium called Chlamydia trachomatis and is transmitted during unprotected sex.

  • Simple treatment to use
  • For chlamydia, it is a single-dose treatment
  • For other infections: 3 tablets a day

Symptoms of chlamydia are reflected in women by the appearance of some pain, irregular vaginal discharge, and increased menstrual bleeding. In men, the disease is manifested by urethral discharge. However, three-quarters of female cases and half of men do not develop any visible symptoms. It is therefore particularly important to have a test if you have had unprotected sex with multiple partners, or if you think you have been in contact with the disease.

Cellulitis is a type of skin tissue infection and is characterised by the accumulation of a mass of fat cells in subcutaneous tissue. This infection can be painful and cause inflammation and burning sensations. It results from the patients’ contraction of a staphylococcus or streptococcus bacteria, following a cut or fracture.

As a macrolide antibiotic, Azithromycin fights the bacterial cells responsible for spreading the infection. This bacterium can multiply the number of these cells through the presence of a protein essential to its reproduction. When the bacteria cannot produce this protein, it becomes vulnerable and the immune system may return to work and kill the infection.

For treatment of STIs and urethral infections, a single dose of azithromycin is enough. Other infections require a longer prescription, at a minimum of three days. When you buy generics, it is crucial to ensure their legality, as some websites sell unlicensed or counterfeit drugs.

What is the active component?

The active agent of Azithromycin is an antibiotic substance of the same name. This drug belongs to the class of macrolide antibiotics and is used to treat many bacterial infections. The active agent stops the bacteria causing the infection. It interferes with the protein synthesis process, essential to the development and spread of the bacteria.


This type of bacteria requires the creation of certain proteins necessary for copying genetic material and multiplying the bacteria. When the antibiotic blocks this function, the growth of the bacteria begins to slow down, and the immune system can destroy what is left.
