Frequently asked question: Can medication be used to prevent infection with HIV after contact with HIV?

If you have had unprotected sexual contact or a needlestick injury when the other person is infected with HIV, consult your specialist or general practitioner as soon as possible. If you do not have an HIV infection yourself, you can get a post-exposure prophylaxis (PEP) (a treatment with anti-HIV drugs). If you start these right away, you reduce the chance of getting an HIV infection. You must start the treatment within 72 hours of the sexual contact, but preferably earlier. Blood should also be taken at various points to follow up whether you are infected by HIV. You must continue to use PEP until the result is definitive. The treatment therefore takes a few weeks. Because the treatment also has negative side effects, the risk must be properly assessed. This means that you have to think carefully before you start taking PEP.
