What is Zontivity (vorapaxar)?
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.
Vorapaxar is used to lower the risk of stroke or serious heart problems in people who have had a heart attack or a blood vessel disorder affecting circulation in the arms and legs.
Vorapaxar is sometimes used together with aspirin or clopidogrel (Plavix).
Vorapaxar may also be used for purposes not listed in this medication guide.

You should not use vorapaxar 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.
Vorapaxar 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.
