PrEP is safe and well-tolerated by most people. It has been used since 2004 to help people who are already living with HIV. However, it can cause mild side effects, including stomach aches, headaches, and weight loss. In a small number of people, it may cause kidney or bone problems. If you think you have any of these side effects from PrEP, contact your doctor.
