Descovy vs Truvada: Pre-Exposure Prophylaxis for HIV

Descovy and Truvada are medications prescribed to reduce the risk of HIV infections for those who are more likely to contract the illness.

According to the Centers for Disease Control and Prevention, more than 1.2 million people in the United States live with HIV and 35,000 people will contract HIV in the United States each year. This information fueled the need for medications that could be used as HIV preventatives, thereby reducing the number of people infected each year.

Truvada was developed by Gilead Sciences and approved by the US Food and Drug Administration in July 2012 for use for pre-exposure prophylaxis (PrEP therapy). The World Health Organization recommends Truvada as the drug of choice for HIV PrEP therapy indicated for nonoccupational exposure. 

Another PrEP therapy drug has been created after Truvada hit the market. Descovy was also made by Gilead Sciences and was approved by the US Food and Drug Administration in 2016. Both are commonly used to prevent the contraction and spread of HIV disease among vulnerable populations.

Descovy vs Truvada

Descovy and Truvada are antiretroviral, reverse transcriptase inhibitor (Anti-HIV) medications used as pre-exposure prophylaxis, also known as PrEP.

Pre-exposure prophylaxis (PrEP) is a term used to describe therapy taken to prevent the spread of disease in people who have not yet contracted the disease-causing agent. PrEP therapy is usually prescribed to prevent a viral infection. In this case, Descovy and Truvada are used to prevent HIV infection.

Descovy contains two ingredients (drugs) called emtricitabine and tenofovir alafenamide which prevent the HIV virus from multiplying (making copies of itself and thereby causing infection). Specifically, Descovy blocks a certain enzyme that HIV uses to multiply.

Truvada works similarly to Descovy by blocking an enzyme used to replicate the HIV virus. Truvada contains two ingredients (drugs) called tenofovir disoproxil fumarate and emtricitabine which prevent the HIV virus from multiplying. Descovy is a newer medication (approved in 2016) while Truvada has been on the market since 2012. Both are used as preventative medications to reduce the risk of HIV infection. 

The main differences between Descovy and Truvada are indication for use, contraindications, and side effects. Here is a chart that compares the similarities and differences between Descovy and Truvada:
