According to a report published last week in the Oxford Journal, pre-exposure prophylaxis, or PrEP – commonly known as Truvada – is as safe as Aspirin.

Truvada reduces the risk of contracting HIV, the virus that causes AIDS, through sex when taken regularly.

Researchers from the David Geffen School of Medicine at the University of California compared five major studies on PrEP for HIV infection against two major studies on Aspirin safety.

They looked at reported side effects for each medication and concluded that the use of Truvada as PrEP was favorable to Aspirin in terms of safety. Researchers, however, cautioned that more studies on long-term use were needed.

“We conclude that FTC-TDF [emtricitabine-tenofovir disoproxil fumarate] for PrEP for HIV infection favorably compares to aspirin in terms of user safety. While long-term studies are needed, providers should feel reassured about the safety of short- and medium-term PrEP for HIV infection with FTC-TDF,” the researchers concluded.

The FDA approved Truvada for use as PrEP in 2012.
