Efavir

Uses
Efavir (Efavirenz) is used as part of a combination antiretroviral treatment plan to reduce the amount of HIV in the blood of patients infected with this virus. The active ingredient in this medicine belongs to a class of drugs known as non-nucleoside reverse transcriptase inhibitors. When used together with other antiretroviral medicines, this drug attacks the virus and reduces its ability to spread, while also helping to prevent it developing a resistance. While treatment with this medicine will not cure the virus, it can help to reduce the patient's chances of developing AIDS and other serious illnesses that may occur in HIV infected patients.

Dosage and Administration

When prescribing a treatment plan for you, your doctor will tell you all of the antiretroviral medicines required to take, and you must follow all instructions given to you. Generally speaking, adult patients are told to take 600mg once per day, alongside any other medicines which have been prescribed. It is very important that this drug is taken every day as prescribed and that no doses are missed.
