Doctors may recommend that patients who have suffered strokes or heart attacks take anywhere from 75 milligrams to 325 milligrams of aspirin daily, according to Mayo Clinic. The 75-milligram dose is less than a baby aspirin, and 325 milligrams is one regular-strength aspirin tablet.
The U.S. Food and Drug Administration warns patients that daily aspirin usage can have serious side effects, including stomach bleeding, kidney failure and bleeding on the brain. Patients and their doctors should carefully evaluate the benefits and risks of daily aspirin usage before beginning treatments. Suddenly stopping daily aspirin usage can result in a rebound effect that can cause blood clots, leading to heart attacks or strokes, according to Mayo Clinic.
