Emtricitabine — Uses, Dosage, Side Effects & Safety

Drug class: Nucleoside Reverse Transcriptase Inhibitor (NRTI)

Overview

Emtricitabine is an antiretroviral medication used to treat HIV-1 infection in adults and children. It is often prescribed as part of combination therapy with other antiretroviral drugs and is also used for HIV pre-exposure prophylaxis (PrEP) to help prevent HIV infection in high-risk individuals. Emtricitabine works by blocking reverse transcriptase, an enzyme HIV needs to multiply. This helps lower the amount of HIV in the body, supports immune function, and reduces the risk of developing AIDS-related complications. Key points for patients: Emtricitabine does not cure HIV, but it helps control the infection. It is important to take this medication exactly as prescribed and not to miss doses. Consistent use reduces the risk of HIV transmission to others.
