Q & As
When taken every day, PrEP lowers the chance of HIV infection by 92 to 99 percent.
Call our PrEP coordinator, Tara, or one of our PrEP educators, Tim or Sergio, and they will help answer your questions, make sure it will be affordable and connect you to a clinician who prescribes PrEP.
For most people, the medicine itself will be completely free. The PrEP team at Stony Brook will connect you to resources that will cover the cost. You might still have copays for the doctor’s visits and lab work, but there are programs to help make sure it’s affordable.
Yes. The PrEP team at Stony Brook Medicine will help you get enrolled in programs that will help pay for PrEP. In New York, PrEP is affordable to just about everyone.
The medicine used for PrEP is called Truvada. Truvada is a combination of two antiretroviral medications (ARVs), called tenofovir disoproxil fumarate (TDF), and emtricitabine (FTC). It was approved to be used for HIV prevention in adults in 2012 and in adolescents weighing over 77 pounds in May 2018.

Truvada was first approved by the FDA in 2004 as one part of an HIV treatment regimen, but Truvada alone is not enough to treat HIV.
Some people experience side effects, but many don’t. The most common side effects occur in the very beginning of taking PrEP, and usually clear up within a few days to a month. These include upset stomach, diarrhea, headache and weight loss.

Because Truvada is processed through the kidneys, kidney function is monitored while you’re on PrEP. This way, in the unlikely event that Truvada affects your kidney function, you find out early and can decide along with your provider how to proceed. When Truvada is stopped, kidney function is shown to return to normal.
In the first three months, you’ll have about three or four doctor’s appointments. After that, you’ll only need to come in once every three months.
PrEP only provides protection against HIV. This means you can still get other STIs, like chlamydia, gonorrhea and syphilis. Condoms would help protect you from these infections.
Any age! Since 2018, as long as you weigh 77 pounds or more, you may be eligible for PrEP.
This is a decision for you to make with your medical provider, but it’s definitely an option.
