Patients Concern
Disease/Condition Glossary
HIV (human immunodeficiency virus): HIV (human immunodeficiency virus) is a virus that attacks the immune system, making the individual susceptible to other infections or illnesses. People with HIV experience flu-like symptoms such as fever, chills, rash, night sweats, muscle aches, tiredness and sore throat. These symptoms usually last for days to several weeks. It spreads through body fluids such as semen, vaginal fluid, and blood. If left untreated, this condition can lead to AIDS (Acquired Immunodeficiency Syndrome). It is a life-long condition, and there is no definite cure for it. However, it can be controlled by treating with antiretroviral agents.

Efavirenz+lamivudine+tenofovir Disoproxil Fumarate is a combination of three medicines: Efavirenz, Lamivudine, and Tenofovir disoproxil fumarate. These drugs belong to a group of medicines called nucleoside analogue reverse transcriptase inhibitors. They work by inhibiting the reverse transcriptase enzyme from working, which is required by the HIV-infected cells to make new viruses. This effect helps to inhibit viral replication. Efavirenz+lamivudine+tenofovir Disoproxil Fumarate also increases the CD4 cell (white blood cells that protect against infection) count in your blood.

No, it is best to take Efavirenz+lamivudine+tenofovir Disoproxil Fumarate on an empty stomach, preferably at bedtime. Food, especially high-fat meals, can cause your body to absorb too much of the medicine too quickly, which increases the likelihood of side effects like dizziness and vivid dreams.
