This can lead to the medicine not helping the person as much as it should. Also, it may even cause side effects or reactions because the quality of the medicine can change.
Does Wegovy Need to Be Refrigerated?
Yes, Wegovy needs to be kept in the refrigerator before it is used. The proper temperature for storing Wegovy is between 36°F to 46°F (2°C to 8°C). This helps make sure the medicine stays stable and works as it should.
Wegovy comes in a single-dose pen that contains a specific amount of semaglutide. Each pen is meant to be used one time only, and then it should be thrown away. Keeping the pen in the refrigerator helps protect the medicine inside.
If the pen is taken out of the fridge, it can still be used, but only for a short time. According to storage instructions, the pen can stay at room temperature, below 86°F (30°C), for up to 28 days. After that time, it should be thrown away, even if it has not been used.
What Happens If Wegovy Isn’t Refrigerated?
If Wegovy is not stored in the refrigerator and it is kept at a high temperature for a long time, it may not work properly. The ingredients in the medicine may break down or change. This means that when someone uses the injection, it may not help them in the way it is supposed to.
Sometimes people might forget to put the pen back in the fridge. If it has only been out for a short time and the room is not too hot, it may still be okay to use. But if the pen is left out in a very warm place or for more than 28 days, it should not be used. This is because the medicine may no longer be safe or effective.
It is very important to always check the pen before using it. If the medicine looks cloudy or has particles in it, do not use it. Wegovy should always be clear and colorless.
Can Wegovy Be Used at Room Temperature?
Yes, Wegovy can be used at room temperature, but only under certain conditions. Once it has been taken out of the refrigerator, it can be kept at room temperature below 86°F (30°C) for up to 28 days. After that, it should be thrown away even if there is still medicine inside.
Before injecting Wegovy, some people prefer to let the pen sit at room temperature for a few minutes. This can make the injection feel more comfortable. Injecting cold medicine can sometimes cause a slight sting or discomfort.
It is very important to keep the pen in a safe and cool place, away from heat and sunlight. Do not store it near a stove, window, or in a hot car. Always keep the pen in its original box to protect it from light.
What Happens If You Don’t Refrigerate Semaglutide?
Semaglutide is the main ingredient in Wegovy. If semaglutide is not kept cold when it should be, it may stop working the way it is supposed to. The drug is sensitive to heat, and high temperatures can break it down.
If a person takes semaglutide that has not been stored correctly, they might notice that it does not help control their appetite or blood sugar as well as it used to. They might even feel like the medicine is not working at all. This is because the active part of the drug may no longer be strong enough to do its job.
Using medicine that has gone bad is not only unhelpful but can also be risky. Always follow the storage instructions closely and check the expiration date. If you are not sure if your pen is still good, ask a pharmacist or a healthcare provider.
How Does Wegovy Have to Be Stored?

Wegovy should always be stored in the refrigerator at a temperature between 36°F and 46°F (2°C to 8°C) until you are ready to use it. Once a pen has been taken out of the fridge, it can stay at room temperature, but not above 86°F (30°C), and for no longer than 28 days.
Do not freeze Wegovy. If it gets frozen, do not use it. Throw it away and get a new pen. Freezing can damage the medicine and make it unusable.
Keep Wegovy in its original box until you are ready to use it. This helps protect the medicine from light, which can also harm it. Do not shake the pen. If it has been dropped or handled roughly, check it before using it.
Can You Inject Wegovy Cold?
Yes, you can inject Wegovy while it is still cold from the refrigerator. It is safe to do so, but some people find that it may cause a little discomfort or stinging when injected cold. This is normal and not harmful.
If you want to make the injection feel better, you can let the pen sit out at room temperature for about 30 minutes before using it. Just make sure it does not get too warm and that it is used within the 28-day time limit if kept out of the fridge.
Always follow the instructions that come with the pen. If you feel unsure, ask your doctor or pharmacist for help.
How Long Does Wegovy Last Once Opened?
Each Wegovy pen is made for just one use. After you inject the medicine, the pen should be thrown away. It is not meant to be saved or used more than one time.
However, if you take a pen out of the refrigerator and do not use it right away, it can last up to 28 days at room temperature. Just make sure the temperature does not go above 86°F (30°C). After 28 days, even if the pen has not been used, it must be thrown away.
Always write the date you took the pen out of the fridge. This will help you remember how long it has been at room temperature. Do not use the pen after that time.
If you have more than one pen, keep the rest in the refrigerator until it is time to use them.
