by e Med Expert staff Medical references reviewed: August, 2018 Many medications are very expensive and people hate to waste them.To avoid a costly visit to the doctor for a new prescription, many people have to consume expired drugs.In general, drugs expiration date is 2-5 years from production date.FDA regulations do not require manufacturers to determine actual long-term drug potency and stability.At the time of the medication expiry date, the drug must be at least 90% of the original potency under proper storage conditions.The expiration date does not indicate a point when a medication loses potency and is no longer effective or becomes harmful.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.
The expiration date, required by law in the United States, beginning in 1979, indicated the date the manufacturer guarantees the full potency and safety of the drug.
This process is not in anyway spontaneous after the expiry date.
Expired drugs have not necessarily lost their potency and efficacy.
