Vorapaxar - oral
Vorapaxar - oral
Vorapaxar increases the risk of bleeding, which may include bleeding in the brain and other serious (possibly fatal) bleeding problems.
Do not use vorapaxar if you have had a stroke, mini-stroke (transient ischemic attack - TIA), or bleeding in the brain in the past; or if you have any current bleeding problems. Discuss the benefits and risks of this medication with your doctor.
Vorapaxar is used to help prevent heart attacks and strokes in people who have had a heart attack or have poor blood flow (peripheral arterial disease).
It works by blocking certain blood cells called platelets from sticking together and forming harmful blood clots. Harmful blood clots can cause heart attacks, strokes, and other serious problems. This "anti-platelet" effect helps keep blood flowing smoothly in your body.
Read the Medication Guide provided by your pharmacist before you start taking vorapaxar and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth with or without food as directed by your doctor, usually once daily. Take it regularly to get the most benefit from it. To help you remember, take it at the same time each day.
Your doctor may direct you to take other anti-platelet drugs (such as aspirin, clopidogrel) with this medication. Follow your doctor's directions carefully.
Do not increase your dose or take this medication more often than prescribed. Your condition will not improve any faster, and your risk of side effects will increase.
It is important to continue taking vorapaxar even if you feel well. Do not stop taking it without consulting your doctor.
Easy bruising/bleeding, such as nosebleeds, may occur. If this effect persists or worsens, tell your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Before using this medication, tell your doctor or pharmacist your medical history, especially of:
While you are taking this medication, it may take longer than usual for bleeding to stop if you have a cut or injury. To lower the chance of getting cut, bruised, or injured, use caution with sharp objects like razors and nail cutters, and avoid activities such as contact sports.
Since vorapaxar stays in your body for a long time, you will still be at risk for bleeding for about 4 weeks after this medication is stopped.
Limit alcoholic beverages. Daily use of alcohol, especially when combined with this medicine, may increase your risk for stomach bleeding.
Before having surgery, tell your doctor or dentist that you are taking this medication and about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.
Some products that may interact with this drug include:
Other medications can affect the removal of vorapaxar from your body, which may affect how vorapaxar works. Examples include azole antifungals (such as itraconazole, ketoconazole), cobicistat, HIV protease inhibitors (such as nelfinavir, ritonavir), hepatitis C virus protease inhibitors (such as boceprevir, telaprevir), macrolide antibiotics (such as clarithromycin), rifamycins (such as rifampin), St. John's wort, drugs used to treat seizures (such as carbamazepine, phenytoin), among others.
Check all prescription and nonprescription medicine labels carefully since many contain pain relievers/fever reducers (aspirin, NSAIDs such as ibuprofen or naproxen). These drugs also have anti-platelet effects and may increase your risk of side effects if taken together. However, if your doctor has directed you to take low-dose aspirin to prevent heart attack or stroke (usually at dosages of 81-325 milligrams a day), you should continue taking the aspirin unless your doctor instructs you otherwise. Ask your doctor or pharmacist for more details.
