Summary
Oxacillin is used to treat bacterial infections, particularly those caused by penicillinase-producing staphylococci, which are bacteria that produce an enzyme breaking down penicillin. It's effective for skin, bone, and respiratory infections, especially when other penicillins are not effective due to bacterial resistance.
Oxacillin works by inhibiting the synthesis of bacterial cell walls, which are essential for their survival. It targets penicillinase-producing staphylococci, effectively killing the bacteria and helping to clear the infection. This makes it useful for treating resistant bacterial infections.
The usual adult dose of oxacillin is 250 mg to 500 mg every 4 to 6 hours, depending on the infection's severity. It can be taken orally or by injection. For children, the dose is based on body weight and should be determined by a doctor.
Common adverse effects of oxacillin include nausea, vomiting, and diarrhea, which are usually mild. Serious adverse effects, like severe allergic reactions, are rare but require immediate medical attention. If you notice any new or worsening symptoms, contact your doctor.
Oxacillin can cause allergic reactions, especially in people allergic to penicillin, which is a type of antibiotic. Symptoms include rash, itching, or difficulty breathing, requiring immediate medical attention. Always inform your doctor of any allergies and follow their guidance closely.
