Oxacillin Injection

Oxacillin injection is used to treat infections caused by certain bacteria. Oxacillin injection is in a class of medications called penicillins. It works by killing bacteria.

Antibiotics such as oxacillin injection will not work for colds, flu, or other viral infections. Taking antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

🔔 How should this medicine be used?

Oxacillin injection comes as a powder to be mixed with fluid or as a premixed product, to be injected intravenously (into a vein). Oxacillin injection can also be given intramuscularly (into a muscle). It is usually given every 4 to 6 hours. The length of your treatment depends on the type of infection you have.

You may receive oxacillin injection in a hospital or you may administer the medication at home. If you will be receiving oxacillin injection at home, your healthcare provider will show you how to use the medication. Be sure that you understand these directions, and ask your healthcare provider if you have any questions.

You should begin to feel better during the first few days of treatment with oxacillin injection. If your symptoms do not improve or get worse, call your doctor.

Use oxacillin injection until you finish the prescription, even if you feel better. If you stop using oxacillin injection too soon or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.

Interestingly, Americans show more favor toward Medicare for All healthcare initiatives than they do toward these efforts when they are labeled as “single payer,” most likely due to the popularity of the Medicare program, STAT
