There are no reports of toxicity from degradation products of currently available drugs. Although specific methods are critical to determine product stability, they do not have to employ any specific technique. The best way to verify long-term stability would be to stockpile supplies, let them sit for years, and even decades, and then test them. The bottom line is that it is best to not use expired medications because there is no guarantee that they will work the way they are supposed to and they may even make you worse. Drug recycling Drug recycling is a fringe and experimental concept but in some places it happens. Since our last publication on this subject, 1 more data have become available. Manufacturers, who contract with analytical laboratories to perform either end product testing or stability studies, or who produce product under contract for other firms are ultimately responsible for the quality of the product and must have copies of all analytical procedures employed and the appropriate documentation to assure their validity on file. We do not believe it is reasonable to perform accelerated testing at very high temperatures for a very short time and expect to extrapolate results to a very long expiration dating period since the actual mechanism of degradation at high temperature may be different than at room temperature. Nonetheless, testing at least annually is considered minimal for compliance with CGMPs. Studies and case reports are lacking on this topic. 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. Oral nitroglycerin NTG , a medication used for angina chest pain , may lose its potency quickly once the medication bottle is opened. Reassuringly, this occurred with a version of the drug that is no longer available. Container-Closure Systems The requirement that stability testing be performed in the same container-closure system as that in which the drug product is marketed has been subject to interpretation. Dealing with racing thoughts? Additionally, the drug lots tested in the SLEP program were kept in their original packaging. Calculating the expiry date At some point after major clinical trials are concluded, but before FDA approval, a series of quality standards are established for each new drug. Expiry dates for drugs can vary dramatically. People who have leftover antibiotics might feel that they can use them safely if they are not expired, or even if they are expired. A stability testing program for bulk drug substances should contain, at the minimum, the following features: In a study of 34 pens that had expired months previously, the decrease in epinephrine content was proportional to the number of months past the expiration date. Renal tubular damage has been reported with use of degraded tetracycline in a formulation that is no longer available. The appropriate conditions will depend on the drug, but may include considerations regarding temperature, humidity, and exposure to light. This is acceptable since it is not the purpose of an accelerated test to determine batch uniformity but rather to test for kinetic degradation. Expiration dating drugs



Policies relating to the expiration dating of unit dose repackaged drugs may be found in Compliance Policy Guide b. Dealing with racing thoughts? So when absolute certainty is required, stick to drug products that are not expired. 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. Since our last publication on this subject, 1 more data have become available. The courts ruled in U. Some firms have chosen, for economical purposes, random dates to test all stability samples of a given product. If it says not to expose it to high temperatures, don't store it right next to the stove. 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. Products sterilized in glass ampuls need not be subjected to sterility testing as part of the stability testing program. Additionally, current requirements for stability testing of drugs should identify if expired products pose a safety risk — and there do not seem to be any other documented cases. While recognizing that case reports are an inaccurate and imprecise way of identifying harms , the lack of documented harms suggests that degradation of useful chemicals into toxic compounds is rare, if it occurs at all. It is important to keep in mind that the expiry date of a drug is based on testing of previously unopened products, stored in its original container, and maintained under typical conditions. Exemptions OTC drug products meeting the exemption of In a study of 34 pens that had expired months previously, the decrease in epinephrine content was proportional to the number of months past the expiration date.

Always feeling tired? If expiry dates are nonsense, extending them could have considerable economic and environmental benefits. Are expired drugs still safe? Consider locking them up. If a drug has degraded, it might not provide the patient with the intended benefit because it has a lower strength than intended. A study of drugs tested by the program showed that two-thirds of the expired medications were stable every time a lot was tested. Additionally, the drug lots tested in the SLEP program were kept in their original packaging. 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. The expiration date of a drug is estimated using stability testing under good manufacturing practices as determined by the Food and Drug Administration FDA. A locked box may be a wise solution. It is also current policy to allow firms to repackage solid dosage units from plastic containers into glass containers because glass has been shown to be a superior moisture and gas barrier. In many cases, medications tested were found to be effective for years past their printed expiry dates; a study by the Journal of Pharmaceutical Sciences found that two-thirds of medications tested through SLEP remained effective for an average of at least four additional years. To help alleviate drug shortages, FDA has also approved extensions of expiration dates when data supporting the extension are available. It is important to keep in mind that the expiry date of a drug is based on testing of previously unopened products, stored in its original container, and maintained under typical conditions. In this case, the potential benefit of saving a life is greater than the potential risk of death by not using it all. The ability for a drug to have an extended shelf life would be dependent upon the actual drug ingredients, presence of preservatives, temperature fluctuations, light, humidity, and other storage conditions. Which drugs should never be used past their expiration date? Many liquid antibiotics have very poor stability, so they must be prepared in the pharmacy at the time of dispensing. Limiting factors with ophthalmic drugs include evaporation of the solvent and the continued ability of the preservative to inhibit microbial growth. Discard unused or expired controlled substances like hydrocodone and acetaminophen Vicodin, Lotab, Norco or oxycodone Oxycontin as soon as possible due to the risk for overdose, theft, or diversion of the medication. SAFETY — There are no published reports of human toxicity due to ingestion, injection, or topical application of a current drug formulation after its expiration date. Should patients use expired medications or not? If a medication is essential for a chronic and potentially life-threatening disease, for example, a heart condition, cancer treatment, seizure, or life-threatening allergy, it is probably wise to get a new prescription before it expires and keep up with refills as needed. Do expired medications lose their potency?

To put the magnitude of that return on investment into everyday terms: Loss of potency can be a major health concern, especially when treating an infection with an antibiotic. 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 will usually involve high temperature and high humidity. But what certainty do we have that this new dosage form will maintain all of these properties over time? What does an expiration date mean? Are there recommendations about the best way to store my medications? Samples should be stored in containers that approximate the market containers; if it is not practical to do so, samples may be stored in other similar containers, provided that data show that such containers will yield results comparable to those obtained with market containers. 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. Please try again. Suspensions are especially susceptible to freezing. Proper storage of medications may help to extend their potency. Preservatives Products formulated to contain preservatives to inhibit microbial growth should be monitored throughout their shelf life to assure the effectiveness of the preservative system. Solutions and suspensions are generally less stable.

Expiry dates are the source of a lot of questions to pharmacists. This includes moving a medication to a different container, which is the normal practice for pharmacies dispensing prescriptions. The preservative system should be monitored at the same stability testing times as other ingredients are monitored. Drugs that exist in solution or as a reconstituted suspension, and that require refrigeration such as amoxicillin suspension , may not have the required potency if used when outdated. Section A locked box may be a wise solution. Due to the potential changes in conditions when a prescription is filled, the US Pharmacopeia , which is the official public standards-setting authority for all prescription and over-the-counter medicines and other healthcare products manufactured or sold in the United States, recommends the practice of beyond-use dates for prescriptions. As long as there is at least one test performed annually, this approach can be quite satisfactory. The "beyond use" date would never be later than the expiration date on the manufacturer's bottle. Thank you, , for signing up. 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. Thus, moisture or oxygen permeation through a 4 oz bottle is more critical than through a 16 oz bottle of similar construction. Particularly with antibiotics, it's important to watch the expiration date because using an expired antibiotic means it may not be potent enough to completely treat your infection, leaving you at risk for a worse one. Would you still consider taking any of them? The American Medical Association has apparently been drawing attention to this issue for over a decade now, but the FDA has made exceptions only in the case of medicine shortages. Bulk Drug Substances Bulk Pharmaceutical Chemicals While expiration dating is not required specifically for bulk drugs in the CGMP regulations, it is feasible and valuable to expect the manufacturer of bulk drug substances to assure that their product is stable for the intended period of use. Each year, drugs from the stockpiles are selected based on their value and pending expiration and analyzed in batches to determine whether their end dates could be safely extended.

Expiry dates for drugs can vary dramatically. How the Beyond-Use Date Is Determined The beyond-use date is determined by the pharmacy when they fill a prescription based on different factors, including: Patients often have questions about drug expiration dates: In many cases, medications tested were found to be effective for years past their printed expiry dates; a study by the Journal of Pharmaceutical Sciences found that two-thirds of medications tested through SLEP remained effective for an average of at least four additional years. In , a report was published that tied degraded tetracycline use with a form of renal tubular kidney damage known as "Fanconi Syndrome"; however, that formulation of tetracycline in no longer marketed in the U. What does an expiration date mean? Combining data compiled at room temperature and at accelerated temperature is possible to justify an expiration dating period of over two years. Each of them had their expiration dates extended, on average, by more than four years, according to research published in the Journal of Pharmaceutical Sciences. Sterility Testing Products manufactured as sterile must maintain that quality throughout the labeled expiration dating period as long as the product is unopened and stored according to labeled instructions. After exposure over different time periods, the quantity of the API, and the other product characteristics, will be assayed again. These results suggest that many drug products may have extended shelf lives beyond their expiration date. All of this is used to estimate what the expiry date should be: Calculating the expiry date At some point after major clinical trials are concluded, but before FDA approval, a series of quality standards are established for each new drug. While recognizing that case reports are an inaccurate and imprecise way of identifying harms , the lack of documented harms suggests that degradation of useful chemicals into toxic compounds is rare, if it occurs at all. While we recommend that all other container sizes be subjected to stability testing, the fact that some may not is not necessarily a violation of CGMPs. But according to a new report from ProPublica, most of those drugs are safe and effective for years after the expiration date. Due to the potential changes in conditions when a prescription is filled, the US Pharmacopeia , which is the official public standards-setting authority for all prescription and over-the-counter medicines and other healthcare products manufactured or sold in the United States, recommends the practice of beyond-use dates for prescriptions. 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. If a medication is essential for a chronic and potentially life-threatening disease, for example, a heart condition, cancer treatment, seizure, or life-threatening allergy, it is probably wise to get a new prescription before it expires and keep up with refills as needed. Again, the evidence is reassuring — with some caveats. However, this was under ideal conditions — not typical use consumer use, where bottles are usually partially consumed, and partially exposed to moisture and light. SLEP is a fee-for-service program through which the labeled shelf life of certain federally stockpiled products can be extended after select products undergo periodic stability testing conducted by FDA. Make sure you are storing your medication according to directions. However, it is difficult for any one consumer or health care provider to know which product could have an extended shelf life. This policy does not apply to liquid drugs because of pH problems resulting from the alkaline nature of glass. Insulin is used to control blood sugar in diabetes and may be susceptible to degradation after its expiration date. Can you use an expired EpiPen?

Products Intended for Reconstitution Any drug product intended for reconstitution and not bearing an expiration date for the unreconstituted product and another expiration date for the product after reconstitution is considered to be out of compliance with Consider locking them up. The beyond-use date is almost always different than the actual expiration date of the drug. Due to the potential changes in conditions when a prescription is filled, the US Pharmacopeia , which is the official public standards-setting authority for all prescription and over-the-counter medicines and other healthcare products manufactured or sold in the United States, recommends the practice of beyond-use dates for prescriptions. Container-Closure Systems The requirement that stability testing be performed in the same container-closure system as that in which the drug product is marketed has been subject to interpretation. Expiry dates are the source of a lot of questions to pharmacists. Potassium iodide, which has been extensively stockpiled for use in a radiation emergency, has shown no significant degradation over many years. For example, if using ibuprofen Advil or acetaminophen Tylenol that's outdated does not relieve your headache, it may have lost its potency. This testing is designed to provide confidence that the product will meet the applicable standards of strength, quality, and purity throughout its shelf-life. And if you leave your prescriptions to cook on the dash of your car in the hot sun, or freeze in the winter, I have encountered both speak with a pharmacist who may be able to get drug-specific stability data. Why or why not? Are expired drugs still safe?

There is no top-down fix in sight. There must be separate stability studies to support each expiration date. Discard unused or expired controlled substances like hydrocodone and acetaminophen Vicodin, Lotab, Norco or oxycodone Oxycontin as soon as possible due to the risk for overdose, theft, or diversion of the medication. Why Beyond-Use Dates? Policies relating to the expiration dating of unit dose repackaged drugs may be found in Compliance Policy Guide b. Expiry dates for drugs can vary dramatically. Generally, the placing of three initial batches into the long term stability program is considered minimal to assure batch uniformity for establishing an expiration date. Pharmaceutical companies don't push back against the FDA "because regulations make it expensive and time-consuming for manufacturers to extend expiration date. 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. Another important point, especially considering the national opioid epidemic. Renal tubular damage has been reported with use of degraded tetracycline in a formulation that is no longer available. However, research on expired EpiPens has been published. For several decades, the program has found that the actual shelf life of many drugs is well beyond the original expiration dates. Each of them had their expiration dates extended, on average, by more than four years, according to research published in the Journal of Pharmaceutical Sciences. For legal and liability reasons, manufacturers will not make recommendations about the stability of drugs past the original expiration date. Satisfactory comparison of container-closure systems may be done by several methods, i. Accelerated Studies When accelerated stability studies are performed, one batch may be adequate in order to establish a tentative expiration date. These dates are typically one year from the date of fill. When absolutely necessary, expired drugs are probably safe, however, the potency may be compromised. Nonetheless, testing at least annually is considered minimal for compliance with CGMPs. The best way to verify long-term stability would be to stockpile supplies, let them sit for years, and even decades, and then test them. The final dosage form may be a mix of the API as well as fillers, binders, and other ingredients to ensure the API is delivered to the body in a reliable and predictable manner. Products liable to degradation by light or moisture should be stored either in a lighted area or under conditions of high humidity unless it can be demonstrated that the packaging will prevent deterioration by that condition of interest.

Discard unused or expired controlled substances like hydrocodone and acetaminophen Vicodin, Lotab, Norco or oxycodone Oxycontin as soon as possible due to the risk for overdose, theft, or diversion of the medication. However, more frequent testing near the end of the anticipated expiration date is often likely to give better information about the actual stability of the finished product. They don't uproot themselves. Test Methods While Depending on the dosage form, stress testing may include short-term exposure to extremes of heat, light, oxidation, and humidity. Drugs that exist in solution or as a reconstituted suspension, and that require refrigeration such as amoxicillin suspension , may not have the required potency if used when outdated. If a medication is essential for a chronic and potentially life-threatening disease, for example, a heart condition, cancer treatment, seizure, or life-threatening allergy, it is probably wise to get a new prescription before it expires and keep up with refills as needed. However, if a capability is check, and the direction is not desktop to god the committed medication, there is no heart that it is field to take the other in most monks.
