We’ve all wondered about using medications past their expiration dates. Is it ever safe? How important are these dates? And how should we dispose of expired medications? Most medications have an expiration date between 12 to 60 months after they are manufactured. If a pharmacist puts your medication into another container, that date will be even shorter and is reflected in the beyond-use date.
U.S. Food and Drug Administration
In the normal course of business, firms typically have an expiration date on their product and, when the product reaches its labeled expiration date, the product is not supposed to be used beyond that date. We all know that the expiration date on a product is usually not always a bright line after which being crossed the product will crash and burn.
It is just a date after which the sponsor or the Agency has no data upon which to recommend continued usage of the product based on their own stability programs. The FDA actually has a program in place for expiration date extension for drugs held in the national stockpile of medications. This program is not open for run-of-the-mill product, but only for those products deemed necessary for storage in the national stockpile.
This is one way the Agency is addressing drug shortages and often the expiration dates are extended by a few months to up to a year.
The term expiration date also refers to the date that a drug patent expires. Understanding Expiration Dates. Expiration dates are especially.
In some parts of the world, doctors face the difficulty of getting medicine more than once a year. The study team tested the stability of five expired drugs that had been returned from the British Antarctic Survey, which operates five bases and two ships in the Antarctic region and has on-site medical and dental facilities. Drugs for the Antarctic operation are ordered annually in May and shipped from the UK in September, arriving at the bases in December after spending several months at sea, the researchers note.
They tested five types of drug, all one to four years past expiration, and compared these to fresh samples of the same medications to see if the expired versions were chemically stable and retained their active ingredient. The drugs included atropine, which is used to treat certain types of pesticide or nerve agent poisonings; nifedipine, a calcium channel blocker that relaxes the heart and blood vessels in cases of high blood pressure and chest pain; flucloxacillin, an antibiotic in the penicillin family; bendroflumethiazide, a diuretic used to treat hypertension; and naproxen, a nonsteroidal anti-inflammatory NSAID painkiller.
Researchers found that all of the tested drugs were stable, and would, theoretically, have still been effective. The researchers caution that their results are limited by the fact that they did not know the exact temperature exposures the returned drugs had experienced. Expiration dates and stability data would be useful to discuss in terms of national stockpiles of antidotes for bioterrorism and chemical warfare, noted Dr.
If left in a car in hot summers in Arizona, California or other hot spots, some drugs could degrade more quickly, she noted. Discover Thomson Reuters. Directory of sites.

Last updated on Jul 22, For many patients, these questions arise because medications can be expensive and it is costly to frequently replace expired — but unused — medications.

The degradation of medicines through exposure to oxygen, moisture, sunlight or other environmental conditions can impact the stability and potency of active compounds.
But how long does it take for different medicines to start breaking down and losing their efficacy? The FDA, in common with other developed pharmaceutical markets, requires drugmakers to guarantee the effectiveness of drugs up to an expiry date a certain period after their production. It hit me — if I could find a colleague to analyse these, it might provide some interesting answers.
The answers that Cantrell and Gerona received were certainly interesting. The programme, established in , is essentially a money-saving initiative relating to the massive US military stockpiles of certain drugs and vaccines. SLEP facilitates an annual testing of drug stockpiles to identify medicines that could be extended beyond their original expiry dates. Consequences and costs So what might the societal cost be of the unnecessary disposal of drugs that have passed their use-by date but may well still be suitable for use?
This is firstly because no one has even begun to understand the extent to which the problem exists; certainly not in any kind of comprehensive way. Secondly, there is extremely little incentive for anyone, least of all pharmaceutical companies, to spend the money required to gain a better understanding of true drug shelf-lives.

After Shoppers Drug Mart recalled. Some drugs are still effective for a long time after their printed drug expiry date. Expiration dates are scientifically based on when manufacturers can guarantee the full effectiveness, purity and safety of an OTC or prescription drug in a closed container, Tomaka explains.
Before ignoring expiration dates on medications, there are a few caveats to keep in mind: These tests of drug stability were in the mids and early s.
I’m one of those people who regularly goes through the medicine cabinet looking for expired medications to toss out. Researchers from the University of California-San Francisco analyzed eight prescription drugs that were between 28 and 40 years beyond the expiration date indicated on the bottle and found that most of the medications retained their potency. Overall, the eight drugs included 14 different active ingredients, including aspirin, codeine and hydrocodone.
It’s long been a quietly accepted fact that many drugs are safe and potent long after they pass their official expiration dates. Given the potential.
The timeline currently is about 2—3 years out, or roughly how long manufacturers believe a product will hold up over time and under stress. Passing this date does not necessarily mean the medicine is suddenly ineffective—it simply means that FDA and manufacturers no longer guarantee its efficacy. Both government and private testing, however, have demonstrated that many “expired” drugs are indeed stable, potent, and viable long beyond their indicated shelf life.
Despite this realization, pharmaceutical industry representatives say it is more important to protect patient safety. Pharmacists and researchers, however, point out that drug makers benefit financially when new orders are made to replace expired medications. With drug costs already high and still rising, the cry for a change is growing louder. The American Medical Association is among the organizations that have pressed for a new approach that can save waste as well as preserve inventories of precious medicines in short supply.

Can be eaten past its shelf life extension deciphers the federal stockpiles. Observing sell-by: expiration date for product on qualifying drugs and drug expiration.
Lee Cantrell, a toxicologist who helps run the California Poison Control System and Roy Gerona, a pharmacist and researcher at the University of California, San Francisco who specializes in analyzing chemicals, teamed up to answer the question: What is the actual shelf life of drugs? The dates on drug labels are simply the point up to which the Food and Drug Administration and pharmaceutical companies guarantee their effectiveness, typically at two or three years.
In his lab, Gerona ran tests on decades-old drugs: antihistamines, pain relievers, stimulants and some inactive diet pills Obocell and Bamadex. The drugs were tested from their original sealed packaging. The findings were astounding: 12 of the 14 compounds had maintained the same potency as when they were manufactured. They were accused of advising patients that it was ok to take expired drugs.
The researchers state that they were reviewing the ways the dates are determined and suggest re-examining the prescription drug dating process, which could save billions of dollars. The researchers found that two-thirds of the expired prescriptions were stable and offered an extended shelf life by more than four years. However, some medications failed to maintain their effectiveness.
According to the authors, the federal government is aware of the extended shelf life of some drugs, stockpiling medications, antidotes and vaccinations in secured locations around the country in case of emergency. The military, CDC and U. Department of Veterans Affairs are among the federal agencies that stockpile.
