Medical authorities state that expired medicine is safe to take, even those that expired years ago. It's true the effectiveness of a drug may decrease over time, but much of the original potency still remains even a decade after the expiration date.

What happens if you take outdated pills?

Expired medical products can be less effective or risky due to a change in chemical composition or a decrease in strength. Certain expired medications are at risk of bacterial growth and sub-potent antibiotics can fail to treat infections, leading to more serious illnesses and antibiotic resistance.

How long can you take medicine after the expiration date?

While it's best only to use non-expired medications, one study conducted by the U.S. military showed that some medications could retain their potency up to one year after the expiration date has passed.
