Common Questions About Aspirin Safety

UNSAFE

Is it safe to use aspirin after the expiration date?

Expired aspirin may have reduced potency and effectiveness. The FDA does not recommend using medications past their expiration date, as the chemical composition may change over time. Some medications can become less effective or potentially harmful. Consult a pharmacist before using any expired medication.

CAUTION

What if aspirin looks different than when purchased?

Changes in color, consistency, or separation in aspirin typically indicate the product has degraded. While this may not pose a safety hazard for non-food items, it usually means reduced effectiveness. If the product has solidified, separated significantly, or changed color dramatically, it is best to replace it.
