Unless you have been directed by your doctor to take low-dosage Aspirin to reduce your risk of heart attack, you should avoid taking a daily dose.

It’s long been a common recommendation for people over 40. Taking a daily baby Aspirin was supposed to reduce the risk of a heart attack and certain cancers. Instead, a new study by the New England Journal of Medicine says the risks outweigh the benefits for many.

Researchers say that “the risk of major hemorrhage was significantly higher with aspirin than with a placebo. Major hemorrhage events primarily involved upper gastrointestinal and intracranial bleeding.”
