Oritavancin Injection

Oritavancin injection is used to treat skin infections caused by certain types of bacteria. Oritavancin is in a class of medications called lipoglycopeptide antibiotics. It works by killing bacteria.

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

Oritavancin injection comes as a powder to be mixed with liquid and given through a needle or catheter placed in your vein. It is usually injected slowly over 3 hours as a one-time dose by a doctor or nurse.

You may experience a reaction while you receive a dose of oritavancin. Tell your doctor immediately if you experience any of these symptoms while you receive oritavancin: sudden reddening of the face, neck, upper chest, or other body part; itching; rash; and hives. Your doctor may slow or stop the infusion until your symptoms improve.

You should begin to feel better after receiving treatment with oritavancin injection. If your symptoms do not improve or get worse, call your doctor.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
