Key Takeaway
Semaglutide should be stored in the refrigerator at 36 to 46 degrees Fahrenheit before first use. Learn complete storage guidelines for pens, vials, and travel.
Semaglutide should be stored in the refrigerator at 36 to 46 degrees Fahrenheit (2 to 8 degrees Celsius) before first use. After first use, it can be kept refrigerated or at room temperature (up to 86 degrees Fahrenheit) for a limited time depending on the formulation. Never freeze semaglutide.
Storage Before First Use
Unopened semaglutide pens and vials should be stored in the refrigerator between 36 and 46 degrees Fahrenheit. Keep the medication in its original carton to protect it from light. Don't store semaglutide in the freezer. If the medication has been accidentally frozen, don't use it, even if it has thawed. Freezing can damage the protein structure of the drug and reduce its effectiveness. Store pens and vials away from the cooling element in the refrigerator to avoid accidental freezing, as the back wall of many refrigerators can drop below 36 degrees.
Storage After First Use
Once an Ozempic pen is first used, it can be stored in the refrigerator or at room temperature (up to 86 degrees Fahrenheit or 30 degrees Celsius) for up to 56 days. After 56 days, discard the pen even if medication remains. Wegovy single-dose pens should be kept refrigerated until the day of use, though they may be kept at room temperature for up to 28 days if needed.

For compounded semaglutide vials, storage after first use depends on the compounding pharmacy's instructions. Most compounded semaglutide should remain refrigerated once opened and used within 28 to 30 days or by the beyond-use date (BUD) printed on the label. Always follow the specific guidance provided by your compounding pharmacy, as formulations vary.
Travel and Transport
When traveling, keep semaglutide in an insulated medication travel case with gel ice packs to maintain refrigeration. Don't place the pen or vial directly against ice, as direct contact can freeze the medication. If you're flying, carry semaglutide in your carry-on bag rather than checked luggage, since cargo holds can reach extreme temperatures. Bring a copy of your prescription or pharmacy label in case security questions arise about the injectable medication.

Avoid leaving semaglutide in a hot car, near a window with direct sunlight, or in any location where temperatures could exceed the safe range. Once the medication has been exposed to temperatures above 86 degrees, it shouldn't be used.
Signs of Improperly Stored Semaglutide
Before each injection, inspect the medication visually. Properly stored semaglutide should be clear and colorless. Don't use the medication if it appears cloudy, has changed color, contains floating particles or flakes, or has been frozen at any point. If the pen or vial has been left out at improved temperatures for an extended period, err on the side of caution and replace it. Using degraded medication can result in reduced therapeutic effect and unpredictable dosing.
What to Consider
Keep semaglutide out of reach of children and pets. Don't store it in a bathroom medicine cabinet, as humidity and temperature fluctuations can degrade the medication. If you receive semaglutide by mail order, check the package immediately upon delivery to ensure the cold chain was maintained. The medication should arrive cool to the touch with intact ice packs. If it arrives warm or without cold packing, contact your pharmacy before using it.
Frequently Asked Questions
Do I need a prescription for Store Semaglutide?
Yes, GLP-1 receptor agonists require a prescription from a licensed healthcare provider. You can obtain a prescription through an in-person visit or a telehealth consultation with a qualified provider.
What are the most common side effects of Store Semaglutide?
The most frequently reported side effects include nausea (especially during dose escalation), decreased appetite, and mild gastrointestinal discomfort. These typically improve as your body adjusts to the medication over 2-4 weeks.
How long does it take for Store Semaglutide to show results?
Most patients begin noticing effects within 4-8 weeks of starting treatment. Full results for weight management typically appear over 12-16 weeks with consistent use and lifestyle modifications.
Related Questions
Can I use semaglutide that was left out overnight?
If the room temperature stayed below 86 degrees Fahrenheit, the medication is likely still usable. Semaglutide is stable at room temperature for the durations listed above (28 to 56 days depending on formulation). A single night at room temperature won't damage the medication as long as it was not exposed to heat or direct sunlight.
How can I tell if my semaglutide has been frozen?
Frozen semaglutide may appear cloudy or contain ice crystals, though it can look normal after thawing. If you suspect your medication was frozen (for example, it was stored too close to the freezer compartment), don't use it. Replace it with a new pen or vial to ensure full potency.
Does semaglutide need to be refrigerated during a power outage?
If your refrigerator loses power, keep the door closed to maintain cold temperatures as long as possible. A full refrigerator can hold safe temperatures for about four hours. If the outage extends beyond that, transfer the medication to a cooler with ice packs. Monitor the temperature to ensure it stays within the 36 to 86 degree Fahrenheit range.
Can I store semaglutide in a mini fridge?
Yes, as long as the mini fridge maintains a consistent temperature between 36 and 46 degrees Fahrenheit. Some mini fridges have inconsistent cooling or can freeze items near the cooling element. Use a refrigerator thermometer to verify the temperature, and avoid placing the medication directly against the cold plate.
