Teefavir Tablet belongs to the class of medicines called ‘antiretroviral agents’ used to treat HIV infection. HIV is a virus that attacks the immune cells of the body leading to decreased immunity. It spreads through body fluids such as semen, vaginal fluid, and blood. Symptoms include fever, chills, rash, night sweats, muscle aches, tiredness, and sore throat that usually last for days to several weeks.

Teefavir Tablet contains Emtricitabine, Tenofovir Disoproxil Fumarate and Efavirenz. Efavirenz is a non-nucleoside reverse transcriptase inhibitor, Emtricitabine is a nucleoside reverse transcriptase inhibitor, and Tenofovir Disoproxil Fumarate is a nucleotide reverse transcriptase inhibitor. They work by inhibiting the reverse transcriptase enzyme production, which is necessary for the multiplication of the viruses. This effect helps to inhibit viral replication.

You should take this medicine exactly as prescribed by the doctor.

Autoimmune diseases (immune cells attack healthy body tissue) may occur months after the start of the treatment. Inform your doctor if you notice any signs such as muscle weakness, weakness in the hands and feet, palpitations (pounding heart), and tremors. Teefavir Tablet may cause osteonecrosis (death of bone tissue due to a decrease in blood supply to the bone) in some patients. The risk of this disease depends on factors such as length of antiretroviral therapy, alcohol use, steroid use, body mass index (BMI), and immunity. Inform your doctor if you notice joint pain, stiffness, and difficulty in movement, as these symptoms may indicate osteonecrosis.

HIV infection: HIV (human immunodeficiency virus) is a virus that attacks the immune system, making the individual susceptible to other conditions 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. This condition can lead to AIDS (Acquired Immunodeficiency Syndrome).
