A beyond-use date is a date placed on a prescription by a pharmacy for compounded medications they prepare, noting when that prescription should no longer be used. This date is determined by the pharmacy when they prepare a compound prescription based on different factors, including:. The beyond-use date is different than an expiration date of a drug. This includes moving a medication to a different container, which is the normal practice for pharmacies dispensing prescriptions. Based on the type of drug, how fast it degrades, dosage, type of container, storage conditions, prescription length, the likelihood of contamination. Based on testing a drug in specific conditions related to storage containers, lighting, temperature, etc. The FDA says it’s dangerous to take medications after their expiration date because they may not be as effective, their chemical composition may have changed, or they may have deteriorated to a point where harmful bacteria could breed. 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. 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. Medications need to be stored safely to help keep their chemical compositions intact and stop them from becoming breeding grounds for bacteria.
USP 797 Guidelines & Standards
The system that most pharmacies use to assign a date beyond which it should no longer be used seems to be a point of confusion. We, myself included, historically have given day beyond use dating to our products without a second thought and no real scientific data to back up that claim. Seems the revised BUD guidance gives some credence to preservatives, sterilization methods, etc, but with a maximum BUD of 45 days.

The increasing cost of health care is a major concern for health systems, patients, and insurance providers nationwide. These devices are designed to contain HD drips, sprays, and vapors that occur during compounding and administration. A study conducted by The University of New Mexico Hospital found that both pharmacy departments and nursing staff preferred Equashield over 2 other products tested. The study was a 4-step process that included a survey of the health care personnel who would be using the CSTDs.
At the end of study, the consensus was that the Equashield components simplified the entire drug compounding and administration processes. Nelson Laboratories performed a test with extreme-use conditions to assess the ability of Equashield to prevent the transfer of microbial contaminants into drug vials. The double-membrane design of Equashield is thought to prevent the ingress of bacteria by protecting the coring-free needles from contamination by environmental microbes.
Nelson Laboratories used 4 groups of vials that contained growth media. These groups were accessed by Equashield syringes, for 5, 7, or 10 times—depending on the group—over a 7-day period. To replicate standard hospital compounding, ISO 5 environmental conditions were used throughout. As an additional extreme measure, one-third of the Equashield syringes and vial adapters were products that had expired.
There was no growth in any of the media-filled vials at the end of the study. Nelson concluded that the double-membrane needleless design of the device is essential for the prevention of the ingress of environmental contaminants into the vial and HD substances from egressing. The results of the Nelson Laboratories study were validated by a similar study done by the University of Toronto.

Beyond-Use Dating Requirements The new USP defines three different classifications of compounded sterile preparations (CSPs).
There has been some controversy over applying the United States Pharmacopeia USP shelf life rules for compounded pharmaceutical products to allergen extract mixes. These rules require that all compounded mixed materials be disposed of every 28 days due to sterility concerns. The allergy industry has successfully challenged this requirement and made the case that allergen extract mixes are an exception to this rule. Besides following routine sterile handling aseptic procedures, compounding mixing personnel are also required to pass a Media Fill Test at least annually.
This is a test of aseptic technique. A written test is also recommended. ALK does not sell nor specifically endorse any Media Fill Test product on the market but can make suggestions upon request. The written test, as well as the guidelines for handling allergenic extracts, are available from www. An abbreviated list of guidelines is also printed in the most recent update of the Allergen Immunotherapy Practice Parameters
USP 797 Guidelines & Standards
Gauge Pressure Sensors. Alternative Fuels. General Industrial OEM. Off-Highway Vehicles. USP is the standard in place governing the sterile preparation of compounded pharmaceuticals. USP covers the compounding of both hazardous and nonhazardous drugs with a focus on the protection of sterile compounds and environments from contamination.
List three proposed changes to USP: Separation of. Hazardous Drug standards, new product categories, new beyond use date. • Identify.
Beyond-use dates for CSPs are rarely based on preparation-specific chemical assay results, which are used with the Arrhenius equation to determine expiration dates see General Notices and Requirements for manufactured products. The majority of CSPs are aqueous solutions in which hydrolysis of dissolved ingredients is the most common chemical degradation reaction. The extent of hydrolysis and other heat-catalyzed degradation reactions at any particular time point in the life of a CSP represents the thermodynamic sum of exposure temperatures and durations.
Such lifetime stability exposure is represented in the mean kinetic temperature calculation see Pharmaceutical Calculations in Prescription Compounding Drug hydrolysis rates increase exponentially with arithmetic temperature increase; thus, exposure of a beta-lactam antibiotic solution for one day at controlled room temperature see General Notices and Requirements will have an equivalent effect on the extent of hydrolysis of approximately 3 to 5 days in cold temperatures see General Notices and Requirements.
Personnel who prepare, dispense, and administer CSPs must store them strictly in accordance with the conditions stated on the label of ingredient products and finished CSPs. When CSPs are known to have been exposed to temperatures warmer than the warmest labeled limit, but not exceeding 40 see General Notices and Requirements for more than 4 hours, such CSPs should be discarded, unless appropriate documentation or direct assay data confirms their continued stability.
Determining Beyond-Use Dates. When CSPs deviate from conditions in the approved labeling of manufactured products contained in CSPs, compounding personnel may consult the manufacturer of particular products for advice on assigning beyond-use dates based on chemical and physical stability parameters. Beyond-use dates for CSPs that are prepared strictly in accordance with manufacturers’ product labeling must be those specified in that labeling, or from appropriate literature sources or direct testing.
In addition, the pharmacist may refer to applicable publications to obtain relevant stability, compatibility, and degradation information regarding the drug or its congeners. When assigning a beyond-use date, pharmacists should consult and apply drug-specific and general stability documentation and literature where available, and they should consider the nature of drug and its degradation mechanism, the container in which it is packaged, the expected storage conditions, and the intended duration of therapy see Expiration Date and Beyond-Use Date under Labeling in the General Notices and Requirements.
Stability information must be carefully interpreted in relation to the actual compounded formulation and conditions for storage and use.
Beyond-Use and Expiration Date Differences
Featured Issue Featured Supplements. Subscribe Jobs. The USP Chapter was introduced in to provide regulation to pharmacies on quality standards for compounding sterile products CSPs. USP was subsequently introduced in , with an implementation date of December The purpose of this chapter is to describe practice and quality standards for handling hazardous drugs.
Discuss the two factors that determine the beyond-use date. the evolution of pharmacy compounding guidelines up to present day USP Chapter.
Chapters and of the USP define the guidelines for stability testing and beyond-use dating of non-sterile and sterile products respectively. Information regarding beyond-use dating of sterile products is extensive and the reader is referred to USP Chapter www. If valid stability data is not available for a specific non-sterile preparation, the USP provides labeling guidelines based on the water content of the final product. The compounder must also consider other factors such as storage requirements, duration of use of the given product, the mechanism by which the drug is normally degraded, and the container in which the drug will be packaged.
The following USP recommendations apply to maximum beyond-use dates for preparations that are packaged in tight, light-resistant containers and stored at controlled room temperatures unless otherwise stated in the USP. Please refer to the complete USP statement on nonsterile beyond-use dates for additional information on this complex topic. If the solid preparation is formulated from USP products, a 6 month beyond-use date should be assigned.
Non-aqueous liquid preparations made from USP products should bear a beyond-use date of 6 months.
Infusion – July/August 2017
To support compounding of products that are sterile and chemically stable, beyond use dating of admixtures must include a thorough evaluation of appropriate resources. In most instances, resources provide documentation of a specific compounded admixture, at a specific concentration and storage parameters, that does not coincide with current operations or patient-specific requirements.
To meet the operational demands of a pharmacy, institutions employ a referenced guideline approach to guide decision making for safe sterile admixing.
Beyond Use Dating – 28 Day Shelf Life for Compounded Products? There has been some controversy over applying the United States Pharmacopeia (USP).
The compounding of medications is a fundamental part of pharmacy practice. All compounding personnel, mainly pharmacists and pharmacy technicians, are responsible for compounding and dispensing sterile products and preparations of correct ingredient identity, purity freedom from physical contaminants, such as precipitates, 1 and chemical contaminants , strength including stability 2 and compatibility , and sterility and for dispensing them in appropriate containers that are labeled accurately and appropriately for the end user.
In contemporary health care organizations, patients receive compounded sterile preparations CSPs that are stored for extended periods before use. It has long been recognized that extended storage of CSPs may allow for the growth of a pathological bioburden of microorganisms 3 and that patient morbidity and mortality can result from contaminated or incorrectly compounded sterile preparations.

Compounding is an integral part of pharmacy practice and is essential to the provision of health care. Compounders must be familiar with statutes and regulations that govern compounding because these requirements vary from state to state. The compounder is responsible for compounding preparations of acceptable strength, quality, and purity with appropriate packaging and labeling in accordance with good compounding practices see Good Compounding Practices , official standards, and relevant scientific data and information.
Compounders engaging in compounding should have to continually expand their compounding knowledge by participating in seminars, studying appropriate literature, and consulting colleagues. The compounder is responsible for ensuring that the quality is built into the compounded preparations of products, with key factors including at least the following general principles.
See also Good Compounding Practices Personnel are capable and qualified to perform their assigned duties. Ingredients used in compounding have their expected identity, quality, and purity. Compounded preparations are of acceptable strength, quality, and purity, with appropriate packaging and labeling, and prepared in accordance with good compounding practices, official standards, and relevant scientific data and information. Critical processes are validated to ensure that procedures, when used, will consistently result in the expected qualities in the finished preparation.
The compounding environment is suitable for its intended purpose. Appropriate stability evaluation is performed or determined from the literature for establishing reliable beyond-use dating to ensure that the finished preparations have their expected potency, purity, quality, and characteristics, at least until the labeled beyond-use date.
USP Finalizes Revisions to Sterile Compounding Standards
These revisions differ from the existing chapter in some significant ways — both structure and content. These changes, at least some of them, will undoubtedly require the pharmacy system and processes to undergo some significant adjustments. Although, many of the variations will be easier to implement.
The changes are set to become official and take effect on December 1,

Chapter in Pharmaceutical Compounding — Sterile Preparations issued by the US Pharmacopeia describes the guidelines, procedures and compliance requirements for compounding sterile preparations and sets the standards that apply to all settings in which sterile preparations are compounded. The clean room must include an attached anteroom at the same air quality level ISO Class 8 for movement of personnel and materials in and out of the clean room.
Building and operating a clean room can be an expensive and time-consuming proposition. Fortunately, pharmacies can also comply with requirements using a barrier isolator, also known as a glovebox. A glovebox isolator or barrier isolator provides a physical barrier between pharmacy personnel and the compounding activity.
Traditional clean benches and biosafety cabinets have an open front access area, where there is the possibility that disruptions in the room airflow or poor aseptic technique by the operator will introduce contaminants to the work area. A glove box provides an additional level of protection, as the sterile product is never exposed to the room environment or to compounding personnel directly. When using a glovebox, materials are passed into the main working chamber through an enclosed pass-thru chamber, and accessed through glove ports to perform aseptic manipulations.
Clean air is supplied to the work area through a HEPA filter, providing better than ISO Class 5 conditions under positive pressure within the glovebox. Gloveboxes offer the same or better air quality as a clean bench or biosafety cabinet located within a clean room, plus their design offers some significant advantages in both initial investment and ongoing operating expenses. USP Chapter speaks to aseptic conditions for compounded sterile preparations; however the chapter does not cover in detail the risks to pharmacy personnel associated with handling cytotoxic or other hazardous drugs.
For these special cases of CSPs, a negative pressure glovebox should be used to provide ISO Class 5 conditions while also protecting personnel from exposure.
