There are virtually no reports of toxicity from degradation products of outdated drugs.For example, if a company chooses a three year expiration date, it does not have to test beyond that for prolonged effectiveness.In fact, medication's potency gradually decreases starting from the moment of its manufacture.Even 10 years after the expiration date many pharmaceuticals retain a significant amount of their original potency Important note: 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date.Drugs that exist in solution or as a reconstituted suspension may not have the required potency if used when outdated.
