Oxacillin is an antibiotic from the class of semisynthetic penicillins, used to treat infections caused by gram-positive bacteria, particularly those resistant to regular penicillin, such as penicillinase-producing Staphylococcus aureus. It works by inhibiting bacterial cell wall synthesis, leading to bacterial destruction.

Oxacillin is indicated for the treatment of skin infections, bone infections (osteomyelitis), endocarditis, pneumonia, and other staphylococcal infections. It is usually administered intravenously or intramuscularly, but it may also be available in oral form, depending on the severity of the infection.

Side effects may include allergic reactions (rash, itching, anaphylactic shock), nausea, diarrhea, or changes in liver function. Prolonged use may lead to superinfections with resistant microorganisms. It is important to take oxacillin as prescribed by a healthcare provider, and patients with a penicillin allergy should avoid this medication.
