Azithromycin is an antibiotic used to treat various bacterial infections, including respiratory infections, skin infections, and sexually transmitted diseases. It belongs to a class of drugs called macrolides, which work by inhibiting bacterial protein synthesis, effectively stopping the growth of bacteria. Typically taken as a pill or liquid, Azithromycin is often prescribed for a short duration, usually ranging from a few days to a week. It is important to complete the full course of the medication, even if symptoms improve, to ensure that the infection is fully treated and to prevent antibiotic resistance.
