Many uninsured people who want to use pre-exposure prophylaxis (PrEP) may wonder how they’ll be able to pay for this daily pill that prevents HIV infection.

That said, the cost of necessary clinic visits and tests required prior to being approved to use PrEP may be covered by a number of available resources. For example, the pharmaceutical company Gilead Sciences, which manufactures PrEP, offers a patient medication assistance program (MAP) called Advancing Acccess to qualified adults in the United States who need help paying for Truvada as PrEP.

Eligibility requirements for the program stipulate that individuals must be 18 or older and uninsured—or have had payment declined by their insurance carrier—reside in the United States, and have a family income that qualifies them to get the drug at low or no cost.

Recently, Gilead’s MAP made it easier for those who are eligible to enroll and remain in the program for 12 months instead of six.
