For individuals using compounded semaglutide, understanding its shelf life, particularly when unopened, is crucial for ensuring both efficacy and safety. Unlike FDA-manufactured semaglutide products such as Ozempic® or Wegovy®, compounded semaglutide often does not come with a standardized "expiration date" in the same manner. This distinction necessitates a thorough understanding of storage guidelines and the factors that influence its stability.

The shelf life of compounded semaglutide is primarily dictated by the Beyond-Use Date (BUD) assigned by the compounding pharmacy. This BUD is determined based on the specific formulation, ingredients, and the anticipated stability of the medication under recommended storage conditions. Generally, unopened semaglutide products, when stored properly, can maintain their potency for varying periods.

Several sources indicate that unopened injectable semaglutide products should be refrigerated. Specifically, maintaining a temperature between 36°F and 46°F (2°C to 8°C) is recommended to ensure the stability and effectiveness of the medication. When stored correctly in the refrigerator, unopened compounded semaglutide can often last until the expiration date indicated on the vial. Some reports suggest that unopened compounded semaglutide can remain effective for up to 24 months before mixing with other components, while others state it can last up to 120 days when refrigerated with minimal potency loss.

However, the specific timeframe can vary significantly. For instance, some pharmacies may assign a BUD of between 30 to 90 days for unopened vials. Other formulations might have a shorter lifespan, with some liquid formulations typically lasting 4 to 6 weeks before reconstitution. In some cases, an unopened vial might be considered good for up to 30 days at room temperature, though refrigeration is generally advised for optimal preservation.

It's important to note that semaglutide must be kept refrigerated before use. Once the vial is opened or the first dose is drawn, the clock starts on a shorter usage period. While unopened vials have a more extended stability window, once accessed, the medication's integrity changes. After opening, semaglutide can often be stored at room temperature for a limited duration, sometimes up to 60 days at room temperature, provided it's kept below 86°F. However, for optimal preservation after opening, refrigeration is still the preferred method, and the BUD for opened vials can range from 14–35 days or 28 days, depending on the formulation and pharmacy's guidance.

The presence of an expiration date on a medication is a critical indicator of its potency and safety. Manufacturers conduct extensive testing to determine these dates, ensuring the drug remains effective and free from harmful degradation products. While compounded semaglutide may not always have a traditional expiration date, the BUD serves a similar purpose. It is imperative to adhere to the storage instructions provided by your pharmacist and healthcare provider. Using expired semaglutide or medication that has not been stored properly can lead to reduced effectiveness or potential adverse reactions.

In summary, the shelf life of unopened compounded semaglutide is a variable that depends heavily on the compounding pharmacy's BUD and proper storage. Refrigeration between 36°F and 46°F (2°C to 8°C) is the recommended method for maintaining its stability. While some formulations might be stable for extended periods, others have a shorter window. Always refer to the specific instructions provided with your medication and consult with your healthcare provider or pharmacist if you have any doubts about its usability. The semaglutide itself is the active compound, and its stability is paramount. When a vial has remained sealed and consistently refrigerated, its usability is maximized until the designated BUD.
