But is it safe to take these medicines if they are past their expiry date? Expiry dates are put in place after rigorous trialling and controlled experiments to ensure the safety and effectiveness of the drugs people take. In short, they guarantee the potency of the drug. Medicinal drugs are all chemicals and the rate at which they go off will depend upon their chemical structure, the drug preparation, how they are packaged, environmental conditions, whether they are subject to microbial contamination and their exposure to heat, light, oxygen and water.

Expiry Dates on Prescription Labels
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.
The drug company then proposes an expiration date to the FDA, which that two-thirds of the expired medications were stable every time a lot.
Back to Medicines. Medicines have expiry dates so you know when to use them by. After the expiry date medicines may not be safe or as effective. You should not take medicines after their expiry date. If you’ve had a medicine for a while, check the expiry date before using it. You should also make sure that you’ve stored the medicine properly, as described on the packaging or leaflet. If your medicine looks, tastes or smells different to when you first got it, even if it’s within the expiry date, take it to your pharmacist for advice.
The expiry date usually means that you should not take the medicine after the end of the month given.
Erase expiry date of products: simple action, unpredictable consequences
The term “expired” indicates that has come to its end. People hate expired medicine to be waste. To save money and avoid a trip to the doctor for a new prescription, many people do take expired drugs. The expiration date indicated the date the manufacturer guarantees the full potency and safety of the drug. Drug’s potency begins to reduce from the moment it is manufactured; it is not in anyway spontaneous after the expiry date.
Once the expiration date has passed there is no guarantee that an expired medicine will be safe and effective.
Learn what a beyond-use date means on a prescription and how it differs from the expiration date, as well as tips on how to store medications safely.
You add another small prescription bottle to that too crowded medicine cabinet, the bottles nudge each other out of place, some tumbling out and down the sink. A quick date-inventory finds half of them in varying dates of expiry: a month, 6 months, a year. Tsk, tsk, tsk. What does the expiration date signify? Have the “expired” medications really lost potency? Do they really expire on the expiry dates? Are “expired” medicines harmful? The “expiry date” or “expiration date” does not indicate a point when a medication loses potency and is no longer effective or becomes harmful.
From the manufacturer, the expiration date is the final day it guarantees full potency and safety. It is an estimated date based on stability testing standards determined by the FDA—a date “required by law” generally set at 12 to 60 months after the ‘”manufacture date” of new medicines, usually embossed or printed on the original packaging. For prescriptions filled by the pharmacist, it is usually dated a year after being dispensed from the original container.

Learn about the risks of taking expired medications and over-the-counter drugs. The active ingredients in the medications may no longer work, or may be.
For this purpose, the applicant must carry out studies and determine the shelf life for the medicinal product as well as any special storage instructions. The shelf life of a product can range from a few months to many years. For each medicine, all relevant quality characteristics are summarised in a so-called “specification”. In this specification it is determined whether or to what extent the active ingredient content may be reduced so that the indicated efficacy is still fully guaranteed.
In addition, toxicologically justified limit values are set for any degradation products in order to ensure that no undesirable effects are caused by such impurities. A number of further quality-relevant tests are added depending on the dosage form. For example, in the case of tablets, the time during which the active substance is released must be defined, or in the case of parenteral administration – such as infusion or injection solutions – sterility must be guaranteed. This accumulation of requirements very clearly describes and defines the quality of each medicinal product and is therefore objectively verifiable.
International guidelines specify exactly how shelf life studies of drugs are to be designed.
Posted by Michelle Puglielli. Shelf life is the period of time, from the date of manufacture, that a drug product is expected to remain within its approved product specification while stored under defined conditions. Shelf life is typically expressed in units of months, i. The amount of time a product can stay stable under certain environmental conditions, equates to its shelf life.
Usual time points for testing are at 0, 3, 6, 9, 12, 18, 24, 36 months, etc. New products must also be placed on long-term stability to collect pertinent data that will help advise an expiry date.
It is legally and ethically not permissible to sale medicines after expiry date, the medicines do not really retain full potency as expected when our distribution.
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. But is it safe to use medicines past their expiration date? The expiration date is the final day that the manufacturer guarantees the full potency and safety of a medication. Drug expiration dates exist on most medication labels, including prescription, over-the-counter OTC and dietary herbal supplements.
For legal and liability reasons, manufacturers will not make recommendations about the stability of drugs past the original expiration date. Once the container of medication is opened after production, that expiration date is no longer guaranteed. The expiration date of a drug is estimated using stability testing under good manufacturing practices as determined by the Food and Drug Administration FDA. Drug products marketed in the US typically have an expiration date that extends from 12 to 60 months from the time of manufacturer.
Once the original container is opened, either by the patient or the health care provider who will dispense the drug, that original expiration date on the container can no longer be relied upon.
Drug expiry debate: the myth and the reality
Ever since , the U. Food and Drug Administration FDA has required that pharmaceutical companies put expiration dates on prescription and over-the-counter medicines. That doesn’t mean your bottle of ibuprofen will go bad in the same way as, say, an expired carton of milk. The date that you see printed on a pill bottle is the date until which the medicine’s manufacturer will guarantee the drug’s safety and full potency.
How long a drug actually remains safe and effective, however, is often a matter of debate. Besides some medicines like insulin, nitroglycerin and liquid antibiotics, whose active ingredients are known to be less stable over time, many drugs might have a much longer shelf life than their packaging suggests.
Medicines have expiry dates so you know when to use them by. After the expiry date, medicines may not be safe or lose some or all of their effectiveness.
The global generic pharmaceuticals market is likely to witness strong growth in the next few years owing to the patent expiration of key blockbuster drugs and the judicious cost containment efforts of governments and healthcare service providers worldwide. At the same time, the balance in terms of healthcare expenditure and sales revenue is poised to shift from developed to emerging markets such as India, China, Brazil, Russia, Turkey and South Korea, as huge potential still remains untapped in these countries.
Popular drugs scheduled to lose U. Some large pharmaceutical companies like Bristol Myers, Pfizer, Eli Lilly and Merck have prepared by buying smaller biotech companies that offer interesting alternatives to their drug pipelines, suggesting a refocus on recruitment in these developing areas. Many are looking to replace their blockbuster money-spinners with smaller, more targeted treatments. A strong skills requirement for these new inventions is a positive move for some sectors. A swift move in to emerging markets like Brazil, India and China and alternative business models means a more dynamic global recruitment drive and a greater effort to match skills, new locations and business management as quickly as possible.

Patent expiration opens the door for generic versions which make the healthcare available to the consumers at cheaper costs as compared to the patented drugs.
Expiry date and storage of medicines
VCN — Erasing expiry date of products which are close to expired date or already expired and replacing them with a new expired date is risky for consumers. This problem requires a solution from management agencies.

Most medications are potent and safe after the expiration date. The exceptions are insulin, liquid antibiotics and nitro-glycerine. In general, expiry dates are conservative, and consumers can have confidence that drug labeling claims will be accurate up to, and in some cases well beyond, the labelled expiry date. So when absolute certainty is required, stick to drug products that are not expired.
When absolutely necessary, expired drugs are probably safe, however, the potency may be compromised. And before you flush or toss those expired drugs, find ways to dispose of them in a way that minimizes the environmental impact and potential for harm. Read more Read less.
