Wegovy is a popular prescription medication for weight management. It’s administered as a weekly injection to help adults with obesity or weight-related health issues. Proper storage is key to ensuring the drug remains effective.
Many users wonder, “Does Wegovy need refrigerated?” The answer depends on whether the pen is in use or not. This article explains the storage requirements in clear, simple terms.
By following the right storage practices, you can maintain Wegovy’s potency. This guide covers refrigeration needs, handling tips, and what to do in specific situations.
What Is Wegovy and Why Storage Matters
Wegovy contains semaglutide, a hormone-like drug that helps control appetite. It’s FDA-approved for adults with obesity or conditions like type 2 diabetes. The medication comes in a pre-filled injection pen.
Proper storage keeps Wegovy safe and effective. Incorrect handling, like exposure to heat or freezing, can reduce its potency. This could affect your weight-loss results.
Always follow the storage instructions provided with your prescription. Your pharmacist or doctor can clarify any doubts. Safe storage ensures you get the full benefit of the drug.
Does Wegovy Need Refrigerated?
Yes, Wegovy needs to be refrigerated before use to maintain its stability. Store unused pens in a refrigerator at 36–46°F (2–8°C). This keeps the medication effective until its expiration date.
Once you start using a pen, it can be kept at room temperature, up to 86°F (30°C), for up to 28 days. After this period, discard the pen, even if some medication remains.
Avoid freezing Wegovy, as this can damage it. If a pen freezes, don’t use it—contact your pharmacist for a replacement.
How to Store Unused Wegovy Pens
Unused Wegovy pens must stay in the refrigerator. Keep them in their original carton to protect from light. The ideal temperature is 36–46°F (2–8°C), typically found in the main compartment of a fridge.
Don’t store pens in the freezer or near the freezer compartment. Freezing can ruin the medication. Check your fridge’s temperature to ensure it’s within the safe range.
If you’re unsure about your fridge’s settings, use a thermometer. Keep pens away from the fridge door, where temperatures may fluctuate.
Storing Wegovy After First Use
After your first injection, Wegovy pens can be stored at room temperature. The safe range is 46–86°F (8–30°C) for up to 28 days. This makes it convenient for daily use or travel.
Keep the pen in a cool, dry place away from direct sunlight or heat sources. For example, avoid leaving it in a hot car or near a stove. Always store it with the cap on to protect the needle.
If you prefer, you can continue refrigerating the in-use pen. Just let it reach room temperature before injecting to avoid discomfort.
Traveling with Wegovy
Traveling with Wegovy requires planning to maintain proper storage. For unused pens, use a cooler bag with ice packs to keep them at 36–46°F (2–8°C). Avoid direct contact with ice to prevent freezing.
For in-use pens, room temperature storage is fine for up to 28 days. Carry them in a protective case to shield from heat or sunlight. Check local regulations if traveling internationally.
Always carry your prescription label. This helps with airport security or customs checks. Contact your doctor for advice if traveling for over 28 days.
What to Do If Storage Conditions Are Not Met
If a Wegovy pen is exposed to temperatures outside the recommended range, it may lose effectiveness. For example, don’t use a pen that’s been frozen or heated above 86°F (30°C). Contact your pharmacist for guidance.
If you’re unsure about a pen’s storage history, inspect it. The liquid should be clear and colorless. If it looks cloudy or discolored, discard it and get a replacement.
Never use a pen past its expiration date or after 28 days at room temperature. Proper storage ensures the drug works as intended.
Tips for Safe Handling and Storage
Follow these tips to store Wegovy correctly:
- Check Expiration Dates: Always verify the date before using a pen.
- Use a Fridge Thermometer: Ensure your refrigerator stays at 36–46°F (2–8°C).
- Protect from Light: Keep unused pens in their carton.
- Avoid Heat Sources: Store pens away from ovens, radiators, or hot cars.
Label your pens with the date you first use them. This helps track the 28-day room temperature limit. Proper handling prevents waste and ensures safety.

Disposing of Wegovy Pens Safely
Once a pen is expired or used for 28 days, dispose of it properly. Place it in a sharps container to prevent injury. Many pharmacies offer free containers or disposal programs.
Don’t throw Wegovy pens in regular trash or recycling bins. Check with your local pharmacy or waste management for safe disposal options. Some areas have drop-off sites for medical waste.
If you’re unsure, ask your pharmacist for guidance. Safe disposal protects others and the environment.
Common Storage Mistakes to Avoid
Avoid storing unused Wegovy pens outside the refrigerator. Temperatures above 46°F (8°C) can degrade the medication before use. Always check your fridge’s settings.
Don’t leave in-use pens in extreme heat, like a car in summer. Heat can reduce the drug’s effectiveness. Keep them in a cool, shaded spot.
Never use a pen that’s been frozen or looks damaged. If the liquid appears cloudy or has particles, discard it. Contact your doctor or pharmacist for a replacement.
How Storage Affects Wegovy’s Effectiveness
Proper storage ensures Wegovy remains potent. The active ingredient, semaglutide, is sensitive to temperature and light. Incorrect storage can break it down, reducing its ability to control appetite.
Refrigeration keeps unused pens stable until their expiration date. Room temperature storage for in-use pens is safe but limited to 28 days. Following guidelines maintains the drug’s benefits.
If you suspect improper storage, don’t take chances. Consult your pharmacist to confirm the pen is still safe to use.
When to Consult Your Pharmacist or Doctor
Talk to your pharmacist before using Wegovy if you’re unsure about storage. They can confirm if a pen is still safe after temperature exposure. They’ll also explain proper handling.
Contact your doctor if you notice changes in the medication’s appearance or effectiveness. They can adjust your treatment plan if needed. Regular check-ins help ensure safe use.
If you’re traveling or moving, ask for storage tips. Your healthcare team can provide advice tailored to your situation.
