Does Wegovy Need To Be Refrigerated? Everything You Should Know About Safety and Storage
If you have recently started Wegovy or are considering it as part of a medical weight loss programme, you likely have practical questions about how to handle and store it correctly. Getting this right matters, not just for the medication to work effectively, but for your safety.
Below, we answer the most important questions about Wegovy storage and administration, clearly and without jargon.
At Junction Pharmacy, our medical weight loss service in London includes full clinical guidance on how to use your medication safely. If you have questions or would like support, book a consultation with our team today.
Does Wegovy Need To Be Refrigerated?
Yes. Wegovy (semaglutide) must be stored in a refrigerator at a temperature between 2°C and 8°C. It should be kept in its original packaging to protect it from light and should never be stored near the freezer compartment or placed directly against the back wall of the fridge, where temperatures can drop below the safe threshold.
If Wegovy freezes, it must not be used, even if it appears normal after thawing. Freezing can alter the molecular structure of the medication in ways that are not visible to the naked eye, potentially making it ineffective or unsafe.
Can Wegovy Be Kept Out of the Fridge?
Yes, but only for a limited period. Once removed from the fridge, a Wegovy pen can be stored at room temperature, below 30°C, for up to 28 days. This allows for practical use when travelling or when refrigeration is temporarily unavailable.
After 28 days at room temperature, the pen must be discarded, even if doses remain unused. You should never return a pen to the fridge once it has been stored at room temperature.
What Happens If Wegovy Gets Too Warm?
Heat degrades semaglutide. If a Wegovy pen has been exposed to temperatures above 30°C for any period, it should not be used. Do not attempt to cool it down and continue using it.
Practical tips to avoid heat exposure include:
➤ Never leave your pen in a car, particularly in warm weather
➤ Avoid storing near radiators, windowsills, or in direct sunlight
➤ When travelling, use a medication cooling wallet or insulated pouch
➤ Do not place in hand luggage without appropriate protection in warm climates
Storing your medication correctly is essential to maintaining its effectiveness throughout your treatment.
How Should Wegovy Be Administered Safely?
Wegovy is a once-weekly subcutaneous injection, meaning it is injected just beneath the skin. Correct administration technique is important for both safety and effectiveness.
| Administration Point | Guidance |
|---|---|
| Injection sites | Abdomen, upper thigh, or upper arm. Rotate sites each week. |
| Injection day | Same day each week. Can be changed by up to 2 days if needed. |
| Missed dose | Take within 5 days of the missed dose. If more than 5 days have passed, skip and resume next scheduled dose. |
| Before injecting | Allow the pen to reach room temperature before injecting. Many patients find around 30 minutes sufficient, though no specific time is stated in the product instructions. Check solution is clear and colourless. |
| Needle disposal | Use a sharps bin. Never recap or reuse needles. Do not dispose of in household waste. |
| Pen disposal | Remove needle before disposing of the pen. Follow local council or pharmacy guidance for disposal. |
What Should Wegovy Look Like Before I Use It?
Before each injection, always check the solution in the pen window. Wegovy should appear clear and colourless to pale yellow. Do not use the pen if the solution looks cloudy, discoloured, or contains visible particles. If you are unsure, contact your prescribing clinician or pharmacist before proceeding.
Is It Safe To Travel With Wegovy?
Yes, with the right preparation. When flying, always carry Wegovy in your hand luggage rather than checked baggage, as hold temperatures can drop significantly and may cause freezing. Carry a letter from your prescribing clinician confirming the medication and the need for needles, as this may be required at airport security.
A medical cooling wallet or insulated travel case will keep the pen within the safe temperature range during transit.
