for how long does aspirin stay in your system?

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.
