Pre-Exposure Prophylaxis (PrEP)
Pre-exposure prophylaxis (PrEP) involves the use of a daily (or on-demand) oral HIV medication (called antiretrovirals or HAART) by people who are HIV-negative to prevent HIV infection.
PrEP is different from PEP (post-exposure prophylaxis), as PrEP is taken before exposure to HIV and may be taken on a long-term basis.
How Does It Work?
PrEP usually comes as a combination tablet that contains two medications called tenofovir and emtricitabine (under the brand name Truvada®). It can be taken every day (called daily dosing) or around the time of sexual activity (called intermittent dosing). Daily dosing is recommended for PrEP, as it has been the most widely evaluated in research studies.
A number of studies have looked at the use of PrEP to see if it is effective in lowering the risk of HIV infection. Research has shown that when PrEP is used properly, it is more than 90% effective in preventing HIV.
As of January 1, 2018, PrEP is covered at no cost (free) by BC health insurance (also called BC MSP, BC Carecard, BC Services Card) for people who are at high risk of HIV infection. This includes cis- and transgender men who have sex with men and trans feminine individuals, people who inject drugs, and people who have sex with individuals living with HIV. PrEP is available through the HIV Drug Treatment program at the BC Centre for Excellence in HIV/AIDS.
For any First Nations people in BC who previously had PrEP covered through the First Nations Health Authority, coverage is now only available through the HIV Drug Treatment program.
PrEP is also available free-of-charge for all Inuit people in British Columbia who are receiving benefits through the Non-Insured Healthcare Benefits (NIHB) program. For more information, contact Health Canada at 1-800-232-7301. Inuit people can also access PrEP through the HIV Drug Treatment program.
For Inuit people, filling a prescription for PrEP is the same as for any other prescription. The prescription from the doctor can be filled at any pharmacy in BC. The pharmacy will fill the prescription at no cost and there is no pre-approval form or process needed.

Things To Consider
Any doctor that is licensed to practice in BC can prescribe PrEP for you. Nurse practitioners who have taken the Treatment for HIV Prevention program at the BC Centre for Excellence in HIV/AIDS (BC CfE) can also prescribe PrEP.
It’s important to take PrEP correctly and under the care of a health care provider. Though the medication is fairly safe, taking PrEP does require regular medical visits and blood and urine tests.
PrEP is not meant to replace other methods of HIV prevention. PrEP does not protect against other STIs. Condoms and other barrier methods are still recommended during penetrative sex to prevent HIV.
