Most of us have reached for a painkiller, at one time or another, only to discover the date on the label shows it has expired. It turns out that date stamped on the label actually means a lot. But what does an "expiration" date on medicine really mean? It's based on scientific evidence gathered by the manufacturer showing how long the drug's potency lasts. Companies expose their medications to different environments, different temperatures and humidity levels to see just how long it takes for the medication to degrade to the point that its effectiveness is compromised. The general rule, says pharmacist Mike Fossler, with the American College of Clinical Pharmacology, is that once a drug is degraded by 10 percent it has reached "the end of its useful life." If you take it months or even years past the expiration date, it's unlikely to do you any harm, he says; it just might not do you much good. That may not be a big deal if you're treating a headache, but if you're fighting a bacterial infection with antibiotics like amoxicillin or ciprofloxacin, for example, using less than fully potent drugs could fail to treat the infection and lead to more serious illness. Pharmacist Mohamed Jalloh, a spokesman for the American Pharmacists Association, says there's an even bigger reason not to rely on old drugs: antibiotic resistance. die from infections that have become resistant to antibiotics, according to the Centers for Disease Control and Prevention. When you inadvertently "underdose" yourself by taking antibiotics that aren't full strength, he says, you run the risk that the bacteria you're battling will figure out not only how to defeat this weakened drug, but other antibiotics, too. "If your medicine has expired, don't use it," concurs Ilisa Bernstein, deputy director of the office of compliance in the Food and Drug Administration's Center for Drug Evaluation and Research. In general, it is not recommended to take expired drugs (past the manufacturer expiration date) since they may not have the same effectiveness they had when they were in date. You just don't know and there really isn't a good way to tell. Most drugs don't actually go "bad" but they may have lost potency and thus will not have the desired effect. Now, manufacturers typically use 2- to 3-year expiration dates because it is convenient. They don't need to perform longer stability tests..the short dating assures the purchase of new drugs. In fact, harm from taking expired drugs has only been linked to degraded tetracycline. There are rare reports of kidney damage in patients who took outdated tetracycline in the 1960s, but this is not a common occurrence. A major regulatory body for pharmacy in the United States, known as USP, recommends no more than a one-year expiration date for drugs that are not in their original, unopened package (e.g. This is because re-packaged drugs (not in original bottle) don't have the light protection and the moisture absorbing qualities as pharmacy prescription vials do.
