Get emergency treatment (PEP) after recent exposure to HIV

PEP (post-exposure prophylaxis) is a medicine available to prevent HIV infections if you believe you may have recently been exposed to HIV (for example, from an unprotected sexual encounter or a needle stick).


PEP involves taking a combination of two medications for 28 days. It is important to start PEP as soon as possible, but no more than 72 hours (three days) after a possible exposure to HIV.

Where and when

You can get PEP from your doctor or local emergency department. If you do not have a doctor or your doctor doesn’t know about PEP, you can come to Health Center 1 (1930 S. Broad St., 2nd floor) and say that you may have been exposed to HIV. A healthcare provider will conduct a full evaluation to determine your exposure. Treatment and follow-up is available onsite for those with a possible exposure occurring within the recommended 72-hour time frame.


The cost of PEP varies depending on where you get it and may be free depending on your insurance. Call the Health Information Helpline at (215) 985-2437 to find out where you can get an affordable dose of PEP.
