How long does semaglutide last in the fridge? Stability depends on the product and label, so follow the storage instructions from your pharmacy or label.
Key facts
- Semaglutide + B12 is $157/month (billed $157 every 4 weeks), charged only after a clinician approves it.

- Adults 18 or older. A licensed clinician reviews your health history and decides whether treatment is appropriate for you. Availability depends on the state you live in.
The most accurate answer to how long does semaglutide last in the fridge is: it depends on which semaglutide you have and what the official storage instructions say. Brand name semaglutide pens have FDA reviewed storage limits, while compounded semaglutide follows the dispensing pharmacy's beyond use date. This guide explains what to check on your label, what temperature issues matter most, and when to contact your pharmacy or clinician. If you are using a compounded semaglutide plan through Vitals Vault, your pharmacy instructions are the source to follow.

Direct answer: it depends on your product
Compounded semaglutide
Compounded semaglutide is not FDA approved, and storage time in the refrigerator is set by the dispensing pharmacy as a beyond use date. Check the prescription label and any insert provided with your shipment, and contact the pharmacy if anything is unclear.
Brand name semaglutide pens
FDA approved semaglutide pens have storage rules that can differ before first use and after first use. If you are using a brand product, follow the specific product labeling for that brand and strength.
If you are not sure which you have
Look for the dispensing label and packaging. If it came from a compounding pharmacy, do not assume brand pen timelines apply. If it is an FDA approved pen, the Medication Guide and Instructions for Use describe how to store it.
Details that change how long it stays usable
Refrigerated does not mean forever
Refrigeration slows chemical breakdown, but it does not stop it. For compounded semaglutide, the beyond use date on the pharmacy label reflects stability and sterility limits for that specific preparation, not a one size fits all rule.
Before first use versus after first use
For FDA approved semaglutide pens, storage limits can change once a pen is in use. The Prescribing Information and Instructions for Use explain how long it can be kept and whether it can be kept at room temperature after first use.
Temperature excursions matter
Freezing and overheating can damage peptide medications like semaglutide. FDA labeling for brand products warns against freezing, and compounded products should also be protected from freezing unless your pharmacy instructions say otherwise.
Light and handling
Many injectable medications are packaged to protect them from light. Keep semaglutide in its original carton or as directed, and avoid leaving it in a hot car or near a freezer vent where it can freeze.
What the solution looks like
If your semaglutide looks cloudy, has particles, or changes color, do not use it until you have checked with your pharmacist. Brand product labeling includes appearance checks, and pharmacies can advise what is expected for your compounded formulation.
When to contact a clinician or pharmacy
It was frozen or got hot
If semaglutide froze, sat against a freezer element, or was exposed to high heat, contact your pharmacist for guidance. FDA labeling for brand products instructs patients not to use product that has been frozen.
You missed the beyond use date
If you are past the beyond use date on a compounded semaglutide label, ask the dispensing pharmacy what to do next. Using medication past that date can raise concerns about potency and sterility.
It looks different than usual
Cloudiness, particles, or discoloration are reasons to pause and ask. A pharmacist can help you determine whether the appearance is expected for your product or a sign it should be replaced.
You have severe symptoms
If you develop severe abdominal pain, persistent vomiting, signs of dehydration, or symptoms of an allergic reaction, seek urgent medical care. These are not storage issues, but they are reasons to get evaluated promptly.
Practical storage tips
Use the middle shelf
Avoid the freezer compartment and cold air vents where freezing is more likely.
Keep the label visible
Store it so you can easily check the beyond use date and instructions.
Travel plan ahead
Ask your pharmacy how to keep it in range during travel or shipping delays.
Do not guess after an incident
If you suspect freezing or overheating, confirm next steps with a pharmacist.
Match advice to your product
Pen instructions do not automatically apply to compounded vials or syringes.
Frequently Asked Questions
How long does semaglutide last in the fridge?
There is not one universal time because it depends on the exact product. For compounded semaglutide, use the beyond use date and storage directions on your pharmacy label. For FDA approved pens, follow the Prescribing Information and Instructions for Use for that product.
Does compounded semaglutide have the same fridge life as brand pens?
Not necessarily. Compounded semaglutide is prepared by a pharmacy for an individual prescription and is not FDA approved, so storage timelines come from the dispensing pharmacy. Brand pen timelines should not be used for a compounded vial unless your pharmacy says they apply.
What if my semaglutide froze in the fridge?
Freezing can damage semaglutide. FDA labeling for brand products instructs patients not to use product that has been frozen. If you think it froze, contact your pharmacist or prescribing clinician for next steps.
Can I use semaglutide if it was left out overnight?
The answer depends on your specific product and the temperature it was exposed to. Brand products have defined room temperature limits in their labeling, while compounded products follow pharmacy provided instructions. When in doubt, ask the dispensing pharmacy before using it.
Where can I check the correct storage instructions for my semaglutide?
Check the prescription label and any insert that came with your shipment, especially for compounded semaglutide. If you use an FDA approved pen, the Medication Guide and Instructions for Use include storage directions. You can also ask your pharmacist to confirm what applies to your exact product.
