Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions.

However, if your doctor has directed you to take low-dose aspirin to prevent heart attack or stroke (usually at dosages of 81-325 milligrams a day), you should continue taking the aspirin unless your doctor instructs you otherwise. Ask your doctor or pharmacist for more details.
