Peramivir is an injectable antiviral medication used to treat influenza A and B infections in adults and children. It works by blocking the ability of flu viruses to make copies of themselves, thereby helping reduce or stop the spread of the virus throughout the body. It is available as a single-dose intravenous (IV) infusion, and it is usually given to those who have severe or complicated flu-like symptoms that are not responding to other treatments. It is not a substitute for getting a flu shot each year, but it may be considered as an emergency treatment for flu infections.
Peramivir, sold under the brand name Rapivab, is an antiviral medication used to treat influenza A and B infections [1]. It's specifically indicated for acute uncomplicated influenza in patients who have been experiencing symptoms for no more than two days [2].
Here's a breakdown of key points about Peramivir:
- Type of drug: Antiviral medication
- Class: Neuraminidase inhibitor [2]
- Treats: Influenza A and B infections (acute uncomplicated) [1, 2]
- Administration: Intravenous (IV) injection by a healthcare professional [4]
- Dosage: Typically a single 600mg dose [4]
How it works: Peramivir belongs to a class of drugs called neuraminidase inhibitors. These drugs work by interfering with the release of new influenza viruses from infected cells. Essentially, they block the enzyme neuraminidase, which the virus needs to escape the host cell and spread the infection [2].
Important things to know:
- Peramivir is not a substitute for getting an annual flu vaccination [6].
- It has not been shown to be effective in treating severe influenza requiring hospitalization [6].
- It's only approved for use in patients aged 2 years and older [6]
