Is it safe to stop taking 81 mg aspirin?

A new Dutch study suggests that people who take aspirin at bedtime might get more protection against heart attacks or strokes. The research involved nearly 300 heart attack survivors who were taking aspirin to ward off a second heart attack.
Does aspirin reduce plaque in arteries?
Aspirin’s Proven Benefit When arteries are already narrowed by the buildup of plaque, a clot can block a blood vessel and stop the flow of blood to the brain or heart. Taking a regular dose of aspirin diminishes the ability of your blood to clump together into clots by targeting the body’s smallest blood cells.
What should be avoided when taking aspirin?
What drugs and food should I avoid while taking Aspirin (Bayer Aspirin)? Avoid alcohol. Heavy drinking can increase your risk of stomach bleeding. If you are taking aspirin to prevent heart attack or stroke, avoid also taking ibuprofen (Advil, Motrin).
When Should aspirin be stopped?
People over 70 who don’t have heart disease — or are younger but at increased risk of bleeding — should avoid daily aspirin for prevention. Only certain 40- to 70-year-olds who don’t already have heart disease are at high enough risk to warrant 75 to 100 milligrams of aspirin daily, and that’s for a doctor to decide.
Do you need to taper off baby aspirin?
