Expired drugs have not necessarily lost their potency and efficacy. The expiration date is only an assurance that the labeled potency will last at least until that date. Ongoing research shows that stored under optimal conditions, many drugs retain 90% of their potency for at least five years after the labeled expiration date, and sometimes longer. Even 10 years after the expiration date many pharmaceuticals retain a significant amount of their original potency.2 Solid dosage forms, such as tablets and capsules, are most stable past their expiration date. Drugs that exist in solution or as a reconstituted suspension may not have the required potency if used when outdated. PMC pubMed 2019
