Truvada is a medication used to prevent and treat HIV. It is a combination of two drugs: emtricitabine and tenofovir disoproxil fumarate. It works by blocking HIV from replicating, helping protect the immune system. Truvada is widely known as a PrEP (Pre-Exposure Prophylaxis) medication, which means it allows people who are at high risk to avoid contracting HIV. It can also be part of a treatment plan for those living with HIV.
How Does Truvada Work?
Truvada blocks enzymes that HIV needs to multiply in the body. If taken daily, it can reduce the risk of HIV transmission significantly. For people at risk, such as those with an HIV-positive partner, this medication is life-changing.
Truvada Uses
- HIV Prevention (PrEP): Truvada helps prevent HIV in people at high risk.
- HIV Treatment: It is also part of combination therapies for people who already have HIV.
- Post-Exposure Prophylaxis (PEP): In some cases, Truvada may be used after potential exposure to HIV.
