Indications

Favipiravir is used to treat infections caused by novel or re-emerging pandemic influenza viruses. It is meant only for cases where other influenza antiviral drugs don't work or don't work well enough.

⚠️ Always consult a registered physician before taking any medicine.

Pharmacology

Favipiravir is a new antiviral medicine used against influenza. An enzyme inside the cell converts it into favipiravir ribosyl triphosphate (favipiravir RTP). This form selectively blocks the RNA polymerase (RNA-dependent RNA polymerase) of the influenza virus, so the virus can't replicate.

Its mechanism of action is different from that of the influenza antiviral medicines already in use. In vitro, it works against all types and sub-types of human influenza A, B, and C viruses. It also shows wide anti-viral activity against various influenza virus strains, including avian and swine viruses.

Pregnancy & Breastfeeding

Favipiravir may slow the development of the embryo or cause its death in the early stage of pregnancy. So it should not be given during pregnancy.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.
