Pre-Exposure Prophylaxis or prEP is a medication that an HIV negative person can take to prevent  HIV infection. The medication is called Truvada (Tenofovir and Emtricitabine) and if taken once a  day, it can reduce the risk of HIV infection from sex by more than 90% and from injection drug use by more than 70%. Most health insurance companies cover Truvada including Medi-Cal and Medicare. Patients may need to pay a copay for the medication and may be eligible for co-pay assistance.
