Efavirenz is used together with other medications for the treatment of the infection caused by the human immunodeficiency virus (HIV). Acquired immune deficiency syndrome (AIDS) is caused by the virus known as HIV.

Efavirenz belongs to the class of non-nucleoside reverse transcriptase inhibitors (NNRTIs). It works by decreasing the amount of HIV in the blood. Efavirenz will not cure or prevent HIV infection or AIDS, however, it helps prevent HIV from reproducing and seems to slow down the destruction of the immune system.

This might help delay the development of problems that generally result from AIDS or HIV disease. Efavirenz will not prevent you from spreading HIV to other people. People who receive this medicine might continue to have some of the problems generally associated with AIDS or HIV disease.

The medication is available only with the doctor’s prescription.


The product is available in the following dosing forms:

  1. Tablet
  2. Capsule
