Publishing of 21 CFR Part – Current Good Manufacturing Practice for Finished Pharmaceuticals established requirements concerning the expiration date on a drug product and stability testing to assure the appropriateness of that date. Each drug product may be a unique article because of, for instance, differences in 1 chemical and physical properties of the active ingredients or the excipients, 2 manufacturing procedures, 3 formulations, 4 containers and closures, 5 proposed storage conditions, and 6 the stability of the article to maintain its quality or purity through the use of antioxidants or preservatives. Because of the uniqueness of each drug product, it is virtually impossible to provide one set of rules that can apply to all situations. The CGMPs were purposely written broadly to allow for such unique differences. The absence of an expiration date on any drug product packaged after September 29, , except for those drugs specifically exempt by OTC drug products meeting the exemption of Information obtained from old stock, not previously the subject of stability studies, may also be utilized. 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 There must be separate stability studies to support each expiration date. Initial stability testing by accelerated testing may be performed on a batch smaller than the normal production size as long as the batch is produced by similar equipment as would be used for regular production.
Shelf Life and Expiration Dates
Batches of materials that may no longer be used or sold after a certain time period are normally assigned a shelf life expiration date SLED. This function calculates the SLED from the total shelf life and the production date during the following procedures:. If a total shelf life is not specified, you must manually enter the SLED in the goods receipt document. The term shelf life expiration date SLED is predominantly used in the pharmaceutical industry and food industry.
In the chemical industry, the term expiration date is used as a synonym. The graphic below shows where the SLED, total shelf life and production date are entered and saved.
Expiration date is the date after which your cosmetic product will be expired and this date must be specified only for the cosmetics which shelf life period is
Beyond use dates are different from expiration dates. Expiration dates are required on commercially manufactured products and are determined after extensive study of the product’s stability. Most expiration dates are given in years for commercial products. Beyond use dates are used for compounded preparations and are generally in days or months. The major problem for pharmacists is that the stability of compounded formulations often is not known.
Also, Many instabilities cannot be detected without the use of analytic equipment. This is in contrast to incompatibilities that can be visually observed. It is not possible to use a manufacturer’s expiration date and extrapolate or estimate a beyond use date for a compounded formulation. The compounded formulation probably will not be identical to the manufactured product; it may have a different drug concentration, use different diluents, be a different fill volume, and be packaged in a different container type.

One of the most common issues found during a typical high-haz walkthrough of any lab is the presence of chemicals kept and used past their expiration date. While it may not seem like a big deal to many, especially if those chemicals are old and hardly used, keeping some chemicals too long past their expiration date can spell danger for those working in the lab. Many chemical manufacturers include only a Recommended Retest Date on their bottles, which can seem like a mixed bag at first.
While not necessarily a date by which you should throw out the chemical, this is a date by which the manufacturer should have retested the chemical batch to ensure its safety and quality. Requesting a new certificate of analysis for any chemical that is nearing its retest date is a good way to stay safe when storing and working with these types of chemicals, since this certificate will show whether the chemical has been retested and passed the test.
Expiration dates are more concrete than retest dates, since they indicate at what point a chemical may begin to decline in quality or stability. Expiration dates are most important in chemicals that can form salts or other precipitates over time, like diethyl ether. Diethyl ether and similar chemicals can form dangerous peroxides over the course of years that can explode on contact if disturbed.
Calculation of Approval and Expiration Dates
As a result of SB Concerning the Continuation Under the Sunset Law of the Division of Real Estate , all licensees will be migrated to a calendar year cycle for their license renewal, with licenses expiring on December 31st of every 3rd year. In order to accommodate this transition to a calendar year cycle, the Division of Real Estate has established a transition period for license renewals and reinstatements.
What does this mean for you? Effective January 1, , any license issued will expire on December 31 of the year of issue.
The expiration dating period used would then be the sum of that justified individually at each storage condition. We do not believe it is reasonable.
Dating is not required by US Federal law, with the exception of infant formula and baby foods which must be withdrawn by their expiration date. For all other foods, except dairy products in some states, freshness dating is strictly voluntary on the part of manufacturers.

Best by date: This date guarantees the period of time the product will be at its best flavor or quality — when bread will still taste soft or crackers.
Is the food definitely inedible? What will happen if you eat something after those dates pass? Date labels are, in some cases, not that strict. This excellent overview by Consumer Reports breaks it all down, and we highly recommend giving it a read. The short story is that, for a lot of foods, those dates are a rough suggestion. In fact, the only federally regulated food date label is the one required on infant formula. Other than that, food product dating is completely voluntary, and producers tend to be quite conservative, understanding that conditions in grocery stores and homes might not be ideal.
Nonetheless, most shoppers and home cooks use these dates to gauge freshness and quality. Best by date: This date guarantees the period of time the product will be at its best flavor or quality — when bread will still taste soft or crackers crisp.
Stability Testing Requirements For OTC & Drug Products in the USA
Event-Related Sterility Maintenance Policy defines procedures intended to maintain the sterility of packages until they are used. This document focuses on event-related sterility maintenance of hospital-prepared packages containing sterile supplies wrapped in single-use or reusable materials. Since some supplies have expiration dates and degrade over time, this document covers only those supplies for which the manufacturer or the distributor does not provide expiration dating in the form of labeling, instructions of use, or other statements.
For years, the subject of expiration dating has generated considerable debate. Many hospitals have considered 30 days to be the standard time period for dating hospital wrapped sterile supplies, principally because of 1 and 2 shelf-life studies conducted by the Center for Disease Control.
Chemical stability is only one of many factors involved in defining expiration date and shelf life. This article provides you, the consumer, with the best definitions.
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. Based on stability data provided by the manufacturers and reviewed by FDA, the following extended use dates are supported for specific lot numbers indicated in the searchable table below.
Providers and patients that have the lot numbers in stock will be able to use them through the corresponding new use dates to help with supply. As data become available, this list can continue to expand. FDA is not requiring or recommending that the identified lot numbers in the following table be relabeled with their new use dates. However, if replacement product becomes available during the extension period, then the agency expects the lots in these tables will be replaced and properly disposed of as soon as possible.
