How To Store Wegovy?

Wegovy (semaglutide) pens should be stored in the refrigerator at 36 to 46 degrees Fahrenheit (2 to 8 degrees Celsius). If refrigeration is unavailable, Wegovy can be kept at room temperature below 86 degrees Fahrenheit for up to 28 days. After 28 days outside the fridge, the pen must be discarded even if unused.

Refrigerator Storage Guidelines

Store Wegovy pens in their original carton to protect them from light. Position them in the main body of the refrigerator, not in the door (where temperature fluctuates each time you open it) and not against the back wall (where temperatures can drop low enough to freeze). Check that your refrigerator is consistently between 36 and 46 degrees Fahrenheit by placing a thermometer inside.

Wegovy pens stored properly in the refrigerator remain usable until the expiration date on the carton. If you have multiple pens from a fill, keep all unused pens refrigerated until the day you need them.

Room Temperature Storage

Wegovy pens are single-dose devices, so "after first use" storage isn't a concern for the pen you just injected with. But if you need to store an unused pen outside the refrigerator, you have a 28-day window at room temperature (up to 86 degrees Fahrenheit or 30 degrees Celsius). This 28-day count is cumulative. Any time the pen spends unrefrigerated counts toward that total, even if you move it back and forth between the fridge and room temperature.

Write the date you removed the pen from the refrigerator on the carton or set a calendar reminder. After 28 cumulative days at room temperature, throw the pen away regardless of the printed expiration date.

Freezing and Heat Exposure

Never freeze Wegovy. If a pen has been frozen, don't use it even if it has fully thawed. Freezing disrupts the protein structure of semaglutide and can make the medication less effective or unpredictable. Similarly, don't expose Wegovy to temperatures above 86 degrees Fahrenheit. Leaving a pen in a hot car, near a heater, or in direct sunlight can degrade the medication permanently.

Traveling With Wegovy

Use an insulated medication travel case with gel ice packs when taking Wegovy on the go. Place a barrier (cloth or paper towel) between the ice pack and the pen to prevent freezing on contact. When flying, always carry Wegovy in your carry-on luggage. Checked baggage compartments aren't temperature controlled and can reach freezing or extreme heat. Bring your prescription label to smooth the security screening process.

For longer trips, plan your injection schedule so you know exactly how many pens to bring. If your destination has a refrigerator, store the pens there upon arrival. If you're camping or staying somewhere without reliable refrigeration, the 28-day room temperature window gives you flexibility as long as ambient conditions stay under 86 degrees.

Visual Inspection Before Injection

Before each dose, check the solution through the pen window. Wegovy should look clear, colorless, and particle-free. If the solution appears cloudy, discolored, or contains visible specks or flakes, don't use the pen. These signs may indicate the medication was damaged by improper storage. Replace it with a properly stored pen and contact your pharmacy if you need a refill sooner than expected.

Related Questions

Is Wegovy storage different from Ozempic storage?

Yes, slightly. Both contain semaglutide, but Wegovy single-dose pens allow up to 28 days at room temperature, while Ozempic multi-dose pens allow up to 56 days at room temperature after first use. The refrigerator temperature range (36 to 46 degrees Fahrenheit) is the same for both. Always follow the storage instructions specific to your prescribed product.

What if my Wegovy arrived warm from the pharmacy?

Contact the pharmacy before using it. Mail-order shipments should arrive cool with intact cold packs. If the pen feels warm or the cold packs are fully melted, the medication may have exceeded safe temperature limits during transit. Most pharmacies will replace the shipment at no charge.

Can I put Wegovy back in the fridge after it has been at room temperature?

Yes, but the 28-day room temperature clock doesn't reset. Any time spent out of the refrigerator is cumulative. For example, if a pen was at room temperature for 10 days and then returned to the fridge, you still only have 18 more days of room temperature allowance for that pen.

How should I dispose of used Wegovy pens?

Place each used pen in an FDA-cleared sharps disposal container. Don't recap the pen or remove the needle before disposal. Once the container is full, seal it and follow your local guidelines for sharps waste. Many pharmacies and community programs accept used sharps containers at no cost.
