If you're considering PrEP, you may have questions about how it works, what to expect, or which option is right for you. Mount Sinai offers three ways to get started: message-only, in-person, or by virtual visit (TelePrEP).
About PrEP
How effective is PrEP?
PrEP lowers your risk of getting HIV from sex by about 99 percent, according to the CDC.
What forms of PrEP are available?
PrEP comes in several forms. Your provider will help you determine which option is right for you.
Daily oral PrEP is a pill you take every day. It's more than 99 percent effective at preventing HIV when taken as prescribed.
Long-acting injectable PrEP is given by a health care provider. Depending on the medication, injections may be scheduled every two months or every six months. Your provider will recommend the right option for you.
On-demand PrEP, sometimes called event-driven PrEP or PrEP 2-1-1, involves taking pills before and after a potential exposure rather than every day. Not everyone is eligible for this option, so talk to your provider to find out if it's right for you.
Is PrEP safe?
Health care providers have used PrEP for more than a decade and a half. It's considered very safe. PrEP is only available through a health care provider, so you'll be carefully screened to make sure it's right for you.
What are the side effects of PrEP?
Some people feel nausea, diarrhea, or headache when they start PrEP. These side effects usually go away within a few weeks.
Do I have to take PrEP with food?
No, you can take PrEP with or without food.
Can I drink while I'm on PrEP?
Research suggests alcohol doesn't affect PrEP's effectiveness. If you have questions, speak with your health care provider.
Does PrEP interfere with other prescription medicines?
Research suggests most other prescription medications don't affect PrEP's effectiveness. Tell your provider about any medications you're taking before starting PrEP.
Does PrEP protect me from other sexually transmitted infections?
No. PrEP only prevents HIV, but another medication called DoxyPEP can prevent gonorrhea, chlamydia and syphilis. We often prescribe the two medications together. We still encourage condom use to reduce your risk of other STIs.
What happens if I test positive for HIV?
We'll help you with HIV care and treatment. PrEP isn't a treatment for HIV, and people living with HIV can't take it.
Can I take PrEP if I was just exposed to HIV?
No. PrEP is preventative, not a treatment. If you've been exposed to HIV in the last 72 hours, you may be able to take PEP (post-exposure prophylaxis) instead. Call the 24/7 NYC PEP Hotline at 844-3-PEPNYC (844-373-7692).
Getting Started
Do I need a prescription for PrEP?
Yes. After we review your health information and lab work, our provider will determine if PrEP is appropriate and if so, send a prescription.
Can I get a generic version of PrEP?
One oral generic PrEP medication is approved: tenofovir disoproxil fumarate/emtricitabine. Most private insurers must cover PrEP without cost-sharing. Check with your insurance company to see if you have a grandfathered plan, which may have associated costs.
Is it legal to prescribe PrEP medication online?
Yes. Telehealth providers are legally allowed to prescribe medication online. Our providers are board-certified, licensed, and only see patients within New York state.
Can I get PrEP without going to a doctor's office?
Yes. You can choose Message-Only PrEP, or meet with a provider virtually through TelePrEP. You'll still need lab work for HIV, hepatitis B, hepatitis C, and kidney function before starting PrEP, and repeat labs every three months. With Message-Only PrEP, you’ll be sent a kit to do your own testing at home and send it to our lab. In-person and TelePrEP lab work is done in our clinics.
Message-Only PrEP
How does Message-Only PrEP work?
Message-Only PrEP lets you get started without a video visit. You'll complete a short online form, get tested at home, and receive a prescription within 24 to 48 hours of your results. This option is available for New York residents with commercial insurance only.
Virtual Visit PrEP (TelePrep)
Who is eligible for TelePrEP?
Adults 18 and older living in New York City who are seeking PrEP. Take the eligibility questionnaire here.
What does the TelePrEP process look like?
First, complete the eligibility questionnaire. If eligible, book your appointment online and create a MyMountSinai account if you don't have one. You'll have a video visit with a TelePrEP provider, then schedule a lab draw, ideally within a week of your visit. Once labs are processed, your provider will prescribe three months of PrEP. After 70 days, you'll get a message to schedule your next labs and follow-up visit.
What will my TelePrEP provider ask me?
You'll discuss how PrEP works and its benefits, your sexual health practices, and your individual needs. You may also be tested for HIV, hepatitis B, hepatitis C, kidney function, and other STIs. TelePrEP appointments are limited to PrEP; other health concerns should go to your primary care provider.
What should I know about insurance and costs before starting?
Before scheduling, check with your insurance company to confirm you're in network, that PrEP is covered without cost-sharing, and whether your insurer has specific billing requirements.
Will I see the same provider every time?
Multiple providers handle TelePrEP visits, so you may see different people at follow-ups.
Where do I get my TelePrEP lab work done?
At one of two Mount Sinai TelePrEP sites: the Samuels Practice at Mount Sinai West, or the Jack Martin Fund Center at Mount Sinai Morningside–Harlem Health Center.
How will I get my PrEP medicine?
We recommend Mount Sinai Specialty Pharmacies, which are linked with TelePrEP and can help with copay cards, prior authorizations, and delivery. You can also use your preferred pharmacy through the MyMountSinai portal.
How can I communicate with my provider?
Through the MyMountSinai portal for medical questions, with replies typically within 24 to 48 hours. For nonmedical questions about appointments or refills, email teleprep@mountsinai.org.
Privacy and Cost
Is my personal and medical information secure?
Yes. We use high-level encryption and follow all federal and state privacy standards, including HIPAA.
If I'm on someone else's insurance, will they know I'm taking PrEP?
Details like HIV testing shouldn't appear on insurance statements, though a copay may show. If you're concerned about privacy from a parent, partner, or spouse, call 929-400-7739 to review your options.
What if I have other medical questions?
You can always reach out for an appointment with a provider who can answer your questions and concerns.
