It belongs to a class of medications called non-nucleoside reverse transcriptase inhibitors (NNRTIs).
Efavir is used to treat HIV infections. It works by inhibiting the reverse transcriptase enzyme, which is required for the replication of the virus. It can help to reduce viral load in the body and improve immune function.

Efavir should be stored at room temperature, away from direct sunlight and moisture. It should be stored out of the reach of children and pets. Do not use the medication beyond the expiration date.
Mechanism of Action:
