Peramivir (Intravenous)

Peramivir is an antiviral medicine (neuraminidase inhibitor) used to treat flu symptoms caused by influenza viruses occurring during late fall and early winter.

Overview

Peramivir is a neuraminidase inhibitor, administered intravenously (IV) to block the spread of influenza infection. The infection is contagious and transmitted through respiratory droplets when an infected person coughs or sneezes. If you are within proximity, you are susceptible. Coming in contact with contaminated surfaces is another source of transmission.

U.S. Food and Drug Administration (FDA) approved this medicine for adults and pediatric patients 2 years and older with symptomatic effects for less than three days. Peramivir IV offers immediate delivery of a single dose for patients requiring urgent treatment. This medicine is also the selected choice when patients do not respond to other antiviral oral or inhalant therapies.

  • Patients with hypersensitivity or life-threatening allergic reaction (anaphylaxis) to this medicine or its chemical components should not use this medicine.
