Zetro (Azithromycin 250mg) is an antibiotic used to treat various bacterial infections, such as respiratory infections, skin infections, and sexually transmitted diseases. It works by inhibiting bacterial protein synthesis, which helps to prevent the growth of bacteria.

The typical dosage for Zetro is one 250mg tablet taken orally once daily. The duration of treatment usually depends on the specific infection and your healthcare provider's instructions, often ranging from 3 to 5 days.

Common side effects include nausea, diarrhea, and abdominal pain. If these symptoms are severe or persist, or if you experience any unusual reactions, consult your healthcare provider.
