Oritavancin (oritavancin) — Uses, Dosage, Side Effects & Safety

Drug class: Antibiotic (Lipoglycopeptide)

Overview

Oritavancin is a powerful antibiotic used to treat serious skin and skin structure infections caused by certain bacteria, including methicillin-resistant Staphylococcus aureus (MRSA) and other Gram-positive organisms. It is typically given as a single intravenous (IV) dose in a hospital or clinical setting. Oritavancin works by disrupting the formation of bacterial cell walls, leading to the death of the bacteria. This makes it effective against bacteria that are resistant to other antibiotics. Key points for patients: Oritavancin is not used for viral infections (such as colds or flu). It is usually administered by a healthcare professional. Let your doctor know about all medications and supplements you are taking, as oritavancin can interact with other drugs.
