How accurate are expiry dates on EpiPens and other drugs? August 8, Written by Paul Taylor Question: I always carry an EpiPen auto-injector just in case I need emergency medicine. Now I see in the news that these life-saving products are in short supply. But how long it remains effective is a matter of some debate and conjecture. That uncertainty also applies to other prescription and over-the-counter drugs. More accurate dating might reduce the waste that results from the disposal of unused, expired drugs and could potentially save patients and health-care systems a lot of money. Before reviewing the evidence, though, a bit of background is in order. Pfizer is the sole Canadian supplier of an auto-injector known by the brand name EpiPen that enables patients to quickly give themselves a shot of epinephrine which acts as an antidote to anaphylaxis — a potentially deadly allergic reaction.
These methods include both classical and state-of-the-art technologies as well as new technologies as they emerge over time. During the life cycle of a product, several reasons can arise for making changes in existing analytical methods: Note that replacing an existing method is not the same as adding a new method to a release or stability test panel. Thus, significant changes in the method can create a substantial discontinuity between past and future data sets.
Also, specification acceptance criteria that were based on historical data from the existing method could be affected by the measurement capabilities of the new method.
Pinpointing the expiration date of drug patents can make filing taxes look like child’s play. Each drug has wide ranging intellectual property, with timelines that are ever-changing.
Because drugs can become unsafe or lose potency over time, and the expiration date is as long as the drug company wants to claim its drug will be safe and have the correct potency. I was at the FDA when the rule was issued requiring drug companies to test their products to see how long they remained potent and safe, and then to include an expiration date on the product.
Until the rule was issued, consumers had no idea when how long they could keep their drugs safely. At the FDA, we recognized that there clearly was a need for consumers to have some time frames for discarding drugs. All of us — me included — have drugs in our medicine chests that have gone beyond the expiration date.
Under the FDA rule, drug companies must test their drugs to be sure they are stable for as long a period as the company wants to claim the expiration date is.
Do Antibiotic Expiration Dates Matter? Previous Next Investigative Report: This is part 2 in our special series about antibiotics controversies.
The absence of an expiration date on any drug product packaged after September 29, , except for those drugs specifically exempt by (e), (f), and (g), is cause to initiate regulatory action against the product and/or the responsible firm.
Are expired pharmaceuticals OK to use? A medication’s best-before date. Typically, manufacturers give their best estimate of how long they believe a medication will retain per cent of its potency, he said. After assessing more than drugs, the FDA found that more than 90 per cent were still effective well after their expiration dates, some as long as 15 years later.
In the case of Alesse 21, the pills were sold in western Canada in March and April, but carried an expiry date of last September. Other prescription drugs could also lack effectiveness if the expiration date has gone by, and some could be potentially harmful. For example, taking out-of-date nitroglycerin, used to treat angina, could have severe repercussions if potency has waned, Emberley said.
David Juurlink, head of clinical pharmacology and toxicology at Sunnybrook Health Sciences Centre in Toronto, said concerns about diminished potency depends on the drug and how much time has elapsed since the best-before date. For instance, researchers found ASA pills dropped in strength from milligrams to two milligrams, while codeine barely lost any of its chemical constituents.
Received Jun 15; Accepted Jun 8. Such comprehensive and common language is currently lacking from various guidelines, which confuses implementation and impedes comparisons of different methodologies. The five new terms that are necessary for a coherent discussion of shelf life are: These concepts are already in use, but not named as such.
The article also highlights a key missing element in the discussion of shelf life—a Quality Statement, which defines the quality standard for all key stakeholders. Arguments are presented that for regulatory and statistical reasons the true product shelf life should be defined in terms of a suitably small quantile e.
pharmaceutical products repackaged into unit-dose or single-unit containers, pharmacists must affix a “beyond-use date” that is “one year or less, unless If the expiration date on the prescription label exceeds the manu-facturer’s date, this is a violation. 2 BOARD OF PHARMACY JULY

Pharmacy and Medications Difference Between Shelf Life and Expiration Date of a Medication The term “shelf life” of a drug slightly differs from a drug’s “expiration date”. The shelf life generally relates to a drug’s quality over a specified period of time, whereas the expiration date relates to both quality and safety of a medication at a specific point in time. Shelf Life A drug that has passed its shelf life might still be safe for consumption, but its quality is no longer guaranteed.
Shelf life is variably influenced by storage conditions, such as exposure to heat, light and moisture. A drug’s shelf life is usually shortened if it is not stored in its original container.
But I think it is pretty common to watch the expiry date of the raw materials, and to make the product prior to raw material expiration. And that the finished product expiry date will be based on the stability testing of the finished product.
Background[ edit ] Shelf life is the recommended maximum time for which products or fresh harvested produce can be stored, during which the defined quality of a specified proportion of the goods remains acceptable under expected or specified conditions of distribution, storage and display. If the cans look okay, they are safe to use. Discard cans that are dented, rusted, or swollen.
High-acid canned foods tomatoes, fruits will keep their best quality for 12 to 18 months; low-acid canned foods meats, vegetables for 2 to 5 years. Most food is still edible after the expiration date. In most food stores, waste is minimized by using stock rotation , which involves moving products with the earliest sell by date from the warehouse to the sales area, and then to the front of the shelf, so that most shoppers will pick them up first and thus they are likely to be sold before the end of their shelf life.
This is important, as consumers enjoy fresher goods, and furthermore some stores can be fined for selling out of date products; most if not all would have to mark such products down as wasted , resulting in a financial loss.

Expiry Date Of Medicines: As according to the law, drug manufacturers are required to mark the expiry date of medicine. This date is the guarantee of full potency and safety given by the manufacturer.
The Canadian generic sector posted strong growth throughout much of the last decade however, by the sector began to face strong headwinds, namely from lower generic pricing policies introduced in public and private drug plans. Some generic companies also encountered manufacturing issues because they were unable to access active ingredients, leading to difficulties supplying to their customers. The supply issue amongst generic manufacturers occurred in Canada, US and other parts of the world.
Sales in the Canadian generic market fell to negative territory for the first time in down 5. Canadian market performance of the generic segment is anticipated to remain weak during the short term despite another wave of patent expiries in , as further reforms by public and private drug plans are phased in. Footnote 19 The recent slowdown in the Canadian generic market is reflected in the performance of leading generic companies. Several examples of such rationalizing include: Pfizer reduced its global workforce by 10, between and Footnote 20 Those brand MNEs that are maintaining their manufacturing facilities are reinventing their production models to focus on high-end manufacturing and foraying into other areas such as medical devices, OTC and consumer healthcare products.
With increasing competition and lower generic pricing policies from payers, companies in the generic sector will likely follow the trajectory of brand companies towards cost reduction and rationalizing assets. Canada’s leading generic company Teva consolidated its operations after acquiring Ratiopharm in and sold the Montreal manufacturing facility formerly operated by Ratiopharm. This facility previously employed over people will now be operated by Halo Pharmaceutical, a contract manufacturing organization CMO with a smaller workforce.
MNEs in the generic segment will be challenged in their ability to sustain activity and investment in Canada since the value proposition for attracting investment in the generic sector is a combination of a fast growing domestic market and a low-cost operating environment, as in the case of India.
