Azithromycin belongs to the family of medications known as macrolide antibiotics. It is used to treat certain types of infections that are caused by bacteria. It is most commonly used to treat ear infections (e.g., otitis media), throat infections, lung infections (e.g., pneumonia), and skin infections. It can also be used to prevent mycobacterium avium complex (MAC) infections in people with HIV infection.Azithromycin acts by binding to the 50S ribosomal subunit of susceptible microorganisms and, thus, interfering with microbial protein synthesis. Nucleic acid synthesis is not affected.
Gastrointestinal: dyspepsia, flatulence, mucositis, oral moniliasis, and gastritis.
