Tenofovir and Lamivudine tablets are a combination of two antiretroviral medicines primarily used to treat human immunodeficiency virus (HIV-1) infection in adults and children weighing at least 35 kg. They are also used for post-exposure prophylaxis (PEP) and can manage chronic Hepatitis B virus (HBV) in co-infected individuals. 

• Key Information

• Function: The tablets contain lamivudine (a nucleoside reverse transcriptase inhibitor or NRTI) and tenofovir disoproxil fumarate (a nucleotide reverse transcriptase inhibitor or NtRTI). They work by interfering with enzymes the virus needs to reproduce, which reduces the amount of virus in the body and helps the immune system work better.

• Usage: This medication is used as part of a combination regimen with other antiretroviral agents. It does not cure HIV or AIDS, and precautions must still be taken to prevent the spread of the virus to others.

• Dosage: The typical dosage for adults and pediatric patients weighing at least 35 kg is one tablet taken orally once daily, with or without food.
