Used to treat a wide range of bacterial infections, including respiratory tract infections, skin infections, ear infections, and sexually transmitted infections like chlamydia. It is effective against certain Gram-positive and Gram-negative bacteria, as well as some atypical pathogens such as Mycoplasma and Chlamydia species. Commonly prescribed for community-acquired pneumonia, bronchitis, and sinusitis. Also used in patients with penicillin allergies due to its favorable safety profile. Available in oral, intravenous, and single-dose suspension forms, it offers convenient dosing, often requiring shorter treatment courses compared to other antibiotics.
