What is PrEP?
PrEP is a preventive treatment for people who are HIV-negative but at higher risk of exposure. It uses antiretroviral medications that block the virus from entering immune cells and replicating, helping prevent infection if exposure occurs.
This treatment helps to:
- Shorten the window of vulnerability before potential exposure
- Reduce the risk of acquiring HIV from sex by about 99% when taken as prescribed
- Lower the risk of HIV from injection drug use by at least 74%
- Provide an additional layer of protection alongside other preventive measures
- Support long-term HIV prevention strategies
What to expect during treatment?
Protection depends on consistent use and regular medical follow-up.
- Maximum protection is typically reached after about 7 days for receptive anal sex and about 21 days for receptive vaginal sex or injection drug use.
- Routine HIV testing and follow-up visits are usually required every 3 months.
- Some people experience mild side effects such as nausea, diarrhea, headache, fatigue, or stomach pain, which often improve over time.
- Options may include daily pills or long-acting injections administered by a healthcare provider.
