Medically reviewed on August 21, 2017.
What is Zontivity?
Zontivity (vorapaxar) helps to prevent platelets in your blood from sticking together and forming a blood clot. An unwanted blood clot can occur with certain heart or blood vessel conditions.
Zontivity is sometimes used together with aspirin or clopidogrel (Plavix).
You should not use Zontivity if you have active bleeding, stomach or intestinal bleeding, a head injury, or if you have a history of stroke (including "mini-stroke"), bleeding in your brain, or increased pressure inside the skull.
Zontivity increases your risk of bleeding, which can be severe or life-threatening. Call your doctor or seek emergency medical attention if you have bloody or tarry stools, red or brown urine, any bleeding that will not stop, or if you cough up blood or vomit that looks like coffee grounds.
Before taking this medicine
You should not use Zontivity if you are allergic to vorapaxar, or if you have:
stomach or intestinal bleeding;
a head injury or bleeding in your head;
a history of stroke;
a history of transient ischemic attack (TIA) or "mini-stroke"; or
a history of bleeding in your brain or increased pressure inside the skull.
Zontivity increases your risk of bleeding, which can be severe or life-threatening, especially if:
you have a bleeding or blood clotting disorder such as hemophilia;
you are an older adult;
you are underweight;
you have liver or kidney disease;
you take a blood thinner (warfarin, Coumadin, Jantoven);
you take certain antidepressants (Celexa, Paxil, Prozac, Zoloft, Cymbalta, Effexor, and others); or
you take an NSAID (nonsteroidal anti-inflammatory drug) such as aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve), celecoxib, diclofenac, indomethacin, meloxicam, and others.
To make sure Zontivity is safe for you, tell your doctor if you have recently had any heart procedures, such as:
heart bypass surgery (coronary artery bypass graft, or CABG);
angioplasty (a catheter is inserted to place a "stent" in a blood vessel to open up a blocked or narrowed artery); or
coronary angiography (a special dye is injected into a blood vessel that allows your coronary arteries to be easily seen on an x-ray).
Zontivity is not expected to harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.
It is not known whether vorapaxar passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using this medicine.

If you need surgery or any dental work, tell the surgeon or dentist ahead of time that you are using Zontivity. You may need to stop using the medicine for a short time to prevent bleeding.
