Expiration Dating and Stability Testing for Human Drug Products

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. In manufacturing terms, shelf life can also mean the time that elapses between when the drug is made and the expiration date assigned by the manufacturer. The expiration date of a medication indicates the date the manufacturer or pharmacist guarantees the full potency and safety of a drug. Some medications might retain potency and might be safe briefly following the expiration date, but you must check with a pharmacist about specific medications. Generally, it is not advisable to use a drug beyond its expiration date, unless directed by a pharmacist. Some drugs, such as tetracycline antibiotics, can even be dangerous if used after their expiration date. If a bottle has both the shelf life and expiration date listed, then it is advisable to use the earlier date as the time to avoid consumption.

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.

Most drug products have a labeled shelf life of years, but once the original container is opened, the expiration date on that container no longer.

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.

Are drug expiration dates fit for purpose?

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.

Why are expiration dates important for consumers to pay attention to? Drug expiration dates reflect the time period during which the product is known to remain stable, which means it retains its strength, quality, and purity when it is stored according to its labeled storage conditions. FDA regulations require drug applicants to provide stability testing data with a proposed expiration date and storage conditions when they submit an application for FDA approval of their drug.

This testing is designed to provide confidence that the product will meet the applicable standards of strength, quality, and purity throughout its shelf-life. FDA recommends that applicants and manufacturers follow the recommendations in internationally harmonized guidance documents on stability testing such as the International Council on Harmonization guidance documents ICH Q1 A-F and Q5C. To help alleviate drug shortages, FDA has also approved extensions of expiration dates when data supporting the extension are available.

If a drug has degraded, it might not provide the patient with the intended benefit because it has a lower strength than intended. In addition, when a drug degrades it may yield toxic compounds that could cause consumers to experience unintended side effects. Patients with serious and life-threatening diseases may be particularly vulnerable to potential risks from drugs that have not been stored properly.

An expiration date is a date after which a consumable product such as food or medicine should not be used because it may be spoiled, damaged, or ineffective. The term expiration date also refers to the date that a drug patent expires. Expiration dates are especially important for medications because they offer the only indication about whether the product is still safe to use. Food items, on the other hand, often look or smell bad when they have passed their “best-buy” dates.

Certain medications can be fatal to children or pets if they ingest even the smallest amount; these should be flushed down the sink or toilet once they pass their expiration date. It is especially important to adhere to the expiration dates of pharmaceuticals. Because their chemical composition can change over time, expired medicines risk becoming less potent, less effective, and even harmful. For example, an expired medication might not be able to control the underlying condition as well as a medication that has not reached its expiration date, so using it could have serious consequences.

In some cases, the FDA may extend the expiration date of a drug if there is a shortage of it. The extended expiration date is based on stability data for the medication that has been reviewed by the FDA.

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.

The reason for this is that both expiration dates and beyond-use dates take into consideration the handling and storage factors of the medication. If your medication is moved to another container or mixed with something else, this may shorten the length of its potency and safety, which results in a beyond-use date that differs from the expiration date.

Conversely, if your pharmacist gives you the same bottle the manufacturer sent the medication in, there likely won’t be a beyond-use date, just the expiration date the manufacturer put on the label. This is true for over-the-counter medications as well. The importance of the expiration date differs a bit depending on the type of medication it is, as well as how it has been stored. One study of medications that had been stored for decades showed that most of them were still at 90 percent potency after all that time.

Another comprehensive study done by an independent group called The Medical Letter looked at the safety of expired medications and found that many medications are safe and still at around 90 percent potency for at least five years after their expiration date. However, this does not apply to liquids, which are not as stable.
