Pre-Exposure Prophylaxis (PrEP) for HIV.

What is PrEP?

PrEP stands for “Pre-Exposure Prophylaxis”, meaning it is a tool to stop infection (“prophylaxis”) that is taken before you are exposed to HIV. Current clinical guidelines for PrEP recommend daily use of Truvada, Descovy or generic versions for maximum HIV prevention benefits. 

PrEP is endorsed by the World Health Organization for people who are HIV negative and at risk for becoming positive. It has been shown to be as high as 99% effective at reducing risk for HIV when taken every day (without missing a dose).[i]

PrEP works by disrupting HIV and preventing it from establishing a foothold in the body and causing a systemic infection.

PrEP does not protect against other sexually transmitted infections, and it is not a cure for HIV.

More on PrEP

PrEP is an acronym that describes the overall prevention method (Pre-Exposure Prophylaxis). It isn’t a new concept. Many other drugs are also taken prior to infection to prevent illness (e.g. Malaria medications before going travelling).

In Canada, the drug Truvada (and its generics) as well as the drug Descovy are approved for use as PrEP. All are considered safe and effective forms of PrEP. Speak with your healthcare provider or pharmacist to determine which may work best for you.

Research is currently ongoing, but in the future additional antiretroviral medications may be approved to be used as PrEP such as once monthly injectables.

Other Key Facts

PrEP should be seen not only as a daily pill that prevents HIV, but a comprehensive sexual health plan that links you to ongoing care. In addition to getting a prescription from your doctor, PrEP will require ongoing visits with your doctor every three months to screen for HIV, side effects from the medication, and sexually transmitted infections.
