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. Physicians and pharmaceutical companies, because of legal restrictions and liability concerns, will not sanction such use and may not even comment on the safety or effectiveness of using their products beyond the date on the label. 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. 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. In general, drugs expiration date is 2-5 years from production date.

Though the main risks of using outdated medications lie elsewhere, a rare kidney ailment called renal tubular acidosis has been reported to result from taking the antibiotic tetracycline old enough to have become degraded into other chemicals. The initial case report, involving a form of the drug that is no longer used, was published in Annals of Internal Medicine in 1963. There were a handful of subsequent incidents, leading to a longstanding warning about taking that drug when it is outdated. A 2004 review of the literature on tetracycline and similar antimicrobials suggested that it might be difficult to determine when the kidney ailment is caused by such a drug. A notable problem with taking expired prescription drugs is that they may not deliver enough of their active ingredient to be effective. Some drugs are so unstable that they must be refrigerated or must be mixed by the pharmacist close to the time they are taken. On the other hand, a Defense Department program with the Food and Drug Administration has found that many drugs are effective long after their posted expiration date if they have been stored under ideal conditions.
