Used primarily as an antibiotic to treat bacterial infections, especially those caused by gram-positive organisms. Effective in treating respiratory tract infections, skin and soft tissue infections, and urinary tract infections. Commonly administered in hospital settings for surgical prophylaxis to prevent postoperative infections. Also used in cases where penicillin may not be suitable, offering an alternative for patients with mild penicillin sensitivity. Its broad-spectrum activity makes it useful in initial empiric therapy before pathogen identification.
