Can effient (anti platelet) be used to prevent another stroke in those who have had multiple from clotting disorder ? i am resistant to plavix and allergic to aspirin. brilinta caused cardiac side effects for me. is effient am option?

This is from Lexicomp: "prasugrel can cause significant, sometimes fatal, bleeding. Do not use prasugrel in patients with active pathological bleeding or a history of transient ischemic attack (TIA) or stroke."

Based upon your history, would not choose Effient as the next step, due to potential risks. Instead, seek a second opinion at a local medical school. Your complicated history indicates the need for a thorough multi-specialty evaluation culminating in a logical decision.
