Q & As
PrEP lowers the chance of HIV infection from sex by about 99 percent and from injection drug use by at least 74 percent.
Call or text our PrEP Coordinator, Clarivet, or our PrEP Educators, and they will help answer your questions, assist with insurance navigation and connect you to a clinician who prescribes PrEP.
Most insurance companies must cover the required doctor’s visits, lab work, and at least one PrEP medicine at no cost to you. The PrEP team at Stony Brook will connect you to resources if you still have costs or if you don’t have health insurance.

There are two different medicines that can be used for PrEP. You and your doctor would decide which one is right for you. Both medicines are a combination of two antiretroviral medications (ARVs). One of the medicines, Truvada, is a combination of tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC), and was approved by the FDA for HIV prevention in 2012. The other medicine, Descovy, is a combination of tenofovir alafenamide (TAF) and emtricitabine (FTC) and was approved by the FDA for HIV prevention in 2019.
There are two different types of medicine, one is oral (Truvada or Descovy) which are taken every day, and one is a shot (Apretude) which is given every two months. You and your doctor would decide which one is right for you.
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.

At this time, oral PrEP is FDA-approved for daily use only. There is substantial evidence that for some people, PrEP on-demand or 2-1-1 PrEP is very effective. According to the CDC, taking 2 pills 2-24 hours before sex, 1 pill 24 hours after the first dose, and 1 pill 24 hours after the second dose is effective to prevent HIV.

In the first three months, you’ll have about three or four doctor’s appointments. After that, you'll need an appointment every three months. The appointments can be in person or virtual (telehealth).
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.
Doxycycline Post-Exposure Prophylaxis (DoxyPEP) means taking the antibiotic doxycycline after sex, to decrease your risk of getting a sexually transmitted infection (STI) like syphilis, chlamydia and gonorrhea. It is a morning-after pill for STIs.
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.
