No clinician has signed off this rule yet. It reflects our reading of the guidelines cited below, which has not been independently checked.
Word for word, as generated for the example person below. Figures in the text are theirs.
If you're taking a daily aspirin "just in case" and you've never had a heart attack or stroke, ask your doctor whether you still should be.
Guidance changed here and many people are still on aspirin from an older era. Three large trials (ASPREE, ARRIVE, ASCEND) found that for people who have never had a cardiovascular event, the bleeding it causes roughly cancels the events it prevents. It's no longer routine — it's a case-by-case decision, and it's specifically discouraged over age 70. Don't start or stop it without asking.
