7 days: One Aspirin may have some effect in the body for up to 7 days but at least for one day. In pts with higher risk for bleeding or gastritis or peptic ulcers may be prescribed less often than daily if clinically necessary.

Up to 24 hrs: For up to 24 hrs, but the effect on the platelets is permanent, so for the bleeding effect of it to go away it might take up to 10 days as it is an average lifespan of a platelet.

Depends on dosage-: Half-life = 2-3 hours for low dose, and about 30 hours for higher dosage. Because of the way it acts on your system, especially platelet, it exerts its effect for about 1 wk, hence you are often advised not to take aspirin/aspirin-related products for about 5-7 days before surgery. So, i would say a week is a safe bet here. Good luck.

Aspirin: Blood levels go down quickly but effects on platelets will last for ABOUT 10 -unitll DAYS UNTIL the platelets aspirin affected have died and been replaced. GOOD INFORMATION ON THIS AT WIKIPEDIA
