Ever since 1979 , the U.S. Food and Drug Administration ( FDA ) has demand that pharmaceutic caller put expiration date on ethical drug and over - the - counter medical specialty .
That does n’t entail your bottle of isobutylphenyl propionic acid will go bad in the same way as , say , an expired carton of milk . The engagement that you see printed on a pill bottle is the date until which the medicinal drug ’s manufacturer will guarantee the drug ’s safety and full potential . How long a drug actually stay safe and effective , however , is often a matter of public debate .
Are these pills safe to take after the expiration date on their labels?
Besides some medicine like insulin , nitroglycerin and liquid antibiotics , whose participating ingredients are known to be less static over clip , many drug might have a much long ledge life than their packaging suggests . [ Why Do People Get Sick When the Seasons Change ? ]
But not everyone knows that , so toxicant control sum from time to time get calls from people who are concerned because they accidentally took pass medicinal drug , said Lee Cantrell , theatre director of the San Diego Division of the California Poison Control System .
" The last prison term I check out , I have n’t seen any peer - reviewed documentation of decease medicine causing any problems in hoi polloi , " Cantrell told Live Science . The effectiveness of medicines , however , may degrade over prison term , but there are few studies on the issue , he allege .

That said , several days ago , Cantrell had a rare opportunity to examine an old stash of drug — includingantihistamines , pain relief and dieting pills — found in the back of a pharmacy .
" We found that those medications , some of them at least 40 years past their fabrication date , still retain full potency , " Cantrell say . That study was publish in the journalJAMA Internal Medicinein 2012 . Cantrell publishedanother studyin 2017 showing thatEpiPens — the expensive auto - injectors used to address life - threatening supersensitised reactions — retain 84 percent of their potentiality more than four years past their expiration escort , suggesting that in an emergency , an expired EpiPen would be better than nothing .
In Cantrell ’s view , pharmaceutical companies are the only one that have the money to do long - term studies on drug ’s efficacy , " but there ’s dead no fiscal bonus for them to do it . " ( When the music you require expires , you , or your insurer , devote for more . )
The Union government , however , has a financial incentive to contemplate the ledge life of drugs . The U.S. maintains astockpile of medicinesthat could be needed in the case of an emergency like a terrorist fire or a disease outbreak . In 1986 , the FDA and the U.S. Department of Defense started theShelf - Life Extension Program(SLEP ) to relieve on the costs of replace expired drug in this stockpile .
ASLEPstudyin 2006 tested 122 unlike drugs store under ideal conditions , and as a result , put out the release day of the month of a majority of the drugs in the stockpile by an norm of about 4 years . In 2016 , SLEP helped save $ 2.1 billion that would have been spent replacing exit drugs in the backlog , the Department of Defense reported , according to a ProPublica investigation . Even so , the FDA still strongly admonish consumer against strike expired medicine .
" sealed expired medication are at hazard of bacterial growth and sub - potent antibiotics can fail to treat contagion , leading to more serious illnesses and antibiotic resistance,“the agency say on its site . Questions about specific decease medications are best directed toward your druggist or doctor .
The FDA also encourages people to bestow their idle and expired Master of Education to the National Prescription Drug Take - Back days , host by the U.S. Drug Enforcement Administration ( DEA ) , in part to forbid ill-usage . The White Houseclaimsthat in 2018 these event " tattered record " with closely 3.7 million pounds of unused and expired prescription drugs recovered .
But while the Trump government might see a victory in that gamey number , others will surely see a massive amount ofpharmaceutical wastefulness .
