Let’s get started!

What Is Semaglutide and Why Does Storage Matter?

Semaglutide belongs to a class of medications called glucagon-like peptide-1 receptor agonists (GLP-1 RAs). Initially developed to help regulate blood sugar in type 2 diabetes patients, semaglutide has proven remarkably effective for weight management by reducing appetite and slowing gastric emptying. This dual effect makes it a valuable tool for millions seeking sustainable weight loss.

Proper storage ensures that semaglutide maintains its potency and remains safe to use throughout your treatment. Exposure to improper temperatures, light, or contamination can degrade the medication, reducing its efficacy and potentially leading to inconsistent treatment outcomes.

Understanding how long semaglutide is good for in various conditions is essential — whether you’re using the commercial brand pens, compounded formulations, or oral tablets. Below, we’ll unpack the latest guidance on storage timeframes and temperature stability for different semaglutide products.

Semaglutide Shelf Life: How Long Does It Last?

Brand-Name Semaglutide (Ozempic®, Wegovy®, Zepbound®)

Brand-name versions of semaglutide come in pre-filled injectable pens with manufacturer-specific storage instructions that prioritize stability and safety:

• Unopened Pens:
  Store unopened semaglutide pens in the refrigerator between 36°F and 46°F (2°C to 8°C). Keep pens in their original carton to protect from light.
  Unopened, semaglutide pens remain good until the expiration date printed on the packaging.

• Opened or In-Use Pens:
  After first use, semaglutide pens can be kept at room temperature (59°F to 86°F / 15°C to 30°C) for a limited time. For Ozempic®, pens must be discarded 56 days (8 weeks) after first use regardless of remaining medication.
  For Wegovy®, storage at room temperature is permitted only for up to 28 days after removal from the fridge, beyond which the pen should be discarded.

• Do Not Freeze:
  Freezing semaglutide pens permanently compromises their effectiveness. If pens freeze accidentally, do not use them.

Compounded Semaglutide

Compounded semaglutide, often prescribed through personalized telehealth platforms like TrimRx, offers a flexible alternative tailored to individual needs. However, compounded forms differ from brand-name products in regulation and stability:

• Unopened Vials:
  Typically, compounded semaglutide is stored in the refrigerator and remains good until the expiration date indicated by the compounding pharmacy.

• Opened Vials:
  Traditional recommendations have advised discarding opened compounded semaglutide vials after 28 days if refrigerated. However, recent third-party studies have demonstrated that some compounded semaglutide formulations remain stable at room temperature (up to 77°F / 25°C) for 60 days. This suggests refrigeration may be optional but still preferred, especially in warmer climates.

• Temperature Sensitivity:
  While some variation exists based on the compounding process and preservatives used, most compounded formulations are stable when stored away from extreme heat and direct sunlight. Freezing should be strictly avoided.

Oral Semaglutide (Rybelsus®)

The oral form of semaglutide has different storage guidelines:

• Store tablets at room temperature, protected from moisture and light, ideally in the original bottle with the special cap to prevent exposure to humidity.

• Avoid transferring pills to pill organizers or containers that do not provide moisture protection.

• Discard tablets after expiration and avoid use if the packaging is damaged or compromised.

How to Properly Store Semaglutide at Home

Proper home storage is a vital part of maintaining medication effectiveness. Here are key guidelines to help you keep your semaglutide in optimal condition:

Refrigeration

• Store unopened injectable semaglutide (brand or compounded) between 36°F and 46°F (2°C to 8°C).

• Avoid placing the medication close to the cooling element in your fridge to prevent freezing.

• Keep the medication in its original packaging to shield it from light and accidental contamination.

Room Temperature Storage

• After the initial use of the pen (for brand-name injectables), the medication can be safely kept at room temperature (59°F to 86°F / 15°C to 30°C) for the time frame allowed by the manufacturer.

• Compounded semaglutide may also be stored at room temperature, with stability reportedly lasting up to 60 days based on recent studies.

Handling Tips

• Always inspect your medication before use. It should be clear, colorless, and free of particles. Discard if cloudy, colored, or contains solid particles.

• Never freeze your semaglutide injection pens or vials.

• Keep the medication out of reach of children and pets.

Regularly follow any specific instructions provided by your healthcare provider or the pharmacy that supplied your medication.

Traveling With Semaglutide: Keeping Your Medication Effective On the Go

Traveling with medications like semaglutide can raise concerns about storage and maintaining efficacy. Knowing the current stability profile helps ease these worries:

• Refrigeration No Longer Strictly Required for Compounded Semaglutide:
  Recent evidence supports the stability of compounded semaglutide at room temperature for up to 60 days, allowing greater flexibility during travel.

• Use Insulated Coolers if Preferred:
  Although refrigeration might not be mandatory, keeping injectable semaglutide cool in an insulated bag with ice packs offers extra assurance during hot weather or flights.

• Carry-On Storage:
  Always pack semaglutide in your carry-on luggage to protect it from extreme temperatures in checked baggage or cargo holds.

• Plan Ahead:
  Bring extra medication in case of travel delays and carry a doctor’s note or prescription to avoid issues at security checkpoints.

• Avoid Direct Sunlight and Heat Exposure:
  Prolonged exposure to heat can degrade your medication; store it in shade and cooler places.

If uncertain about storage conditions during your trip, consult your healthcare provider or pharmacist for personalized advice.

How Long Is Semaglutide Good For Once Opened?

The answer varies depending on the product type:

• Ozempic® Pens: Good for up to 56 days after first use at room temperature.

• Wegovy® Pens: Should be discarded 28 days after removal from refrigeration.

• Compounded Semaglutide Vials:
  Traditionally recommended to be discarded 28 days after opening if refrigerated, but recent data suggest stability up to 60 days at room temperature for some formulations. Always verify with your pharmacy.

• Oral Semaglutide Tablets: Use by expiration date; store properly to maintain effectiveness.

At TrimRx, we emphasize the importance of following manufacturer or compounding pharmacy instructions closely and checking with your healthcare provider if you have questions, to ensure your treatment remains safe and effective throughout your journey.

Why Is Proper Storage and Stability Important?

Medication degradation can lead to diminished effectiveness, negatively impacting your health outcomes. This is especially crucial for medications like semaglutide that work in concert with lifestyle changes to manage chronic conditions like obesity and diabetes.

Improper storage can result in:

• Reduced potency, leading to suboptimal blood sugar control or weight loss.

• Increased risk of side effects due to breakdown products.

• Wasted medication and unnecessary additional costs.
