Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Clopidogrel (Plavix) and prasugrel (Effient) are both P2Y12 inhibitors used to prevent heart attacks and strokes, but they have some key differences. Clopidogrel is used for people with a history of heart attack, stroke, or peripheral artery disease, while prasugrel is specifically for those who have had a stent placed after a heart attack. Clopidogrel is typically taken at a dose of 75 mg once daily, whereas prasugrel is taken at 10 mg once daily, with a lower dose for those under 132 lbs. Prasugrel has a higher risk of bleeding compared to clopidogrel and is not recommended for people aged 75 and older or those with a history of stroke or Transient Ischemic Attack (TIA). Both medications are available as lower-cost generics and are taken orally once a day. While clopidogrel can interact with certain medications like omeprazole and esomeprazole, prasugrel has fewer specific drug interactions but should be avoided with alcohol due to increased bleeding risk.
