About Rapivab

What is this medication?

Rapivab, known generically as peramivir, is an antiviral prescription medication used to treat acute, uncomplicated influenza in patients who have experienced flu symptoms for no more than two days. It belongs to a class of drugs called neuraminidase inhibitors, which function by blocking the enzyme that allows the flu virus to spread to healthy cells in the body. Unlike many other flu treatments that come in pill or liquid form, this medication is unique because it is administered as a single dose through an intravenous injection by a healthcare professional.

This medication is approved for use in both adults and pediatric patients who are at least six months of age. While it helps to shorten the time it takes for symptoms to improve, it is not considered a replacement for the yearly flu vaccine, which remains the primary method for preventing the illness. Rapivab specifically targets the flu virus and is not effective against the common cold or other types of infections caused by bacteria rather than viruses.
