How long can Semaglutide stay in the fridge? Unopened Semaglutide pens, like Ozempic and Wegovy, usually stay good in the fridge at the right temperature (36°F to 46°F or 2°C to 8°C) until the expiration date printed on the pen or box. Once you open a pen or take it out of the fridge for the first time, the rules change, and it has a limited time it can be kept either in the fridge or at room temperature. This guide explains all you need to know about keeping Semaglutide safe and effective by storing it the right way.

Why Proper Semaglutide Storage Matters
Storing your medicine correctly is super important. It helps make sure the medicine works the way it should. It also keeps the medicine safe for you to use. Semaglutide is a type of protein. Proteins in medicines can break down if they get too hot or too cold. When this happens, the medicine might not work as well. Or, it might not work at all. In some cases, it could even become unsafe. Following the Semaglutide storage temperature fridge rules is key. It protects your health and your medicine.
Key Semaglutide Storage Rules
Semaglutide comes mainly as an injection in a pen. The storage rules depend on if the pen is new and unopened, or if you have already used it.
- Unopened Pens: These pens need to be kept cold. The fridge is the best place for them.
- Opened or In-Use Pens: Once you start using a pen, or if you take a new pen out of the fridge, the storage rules change. You usually have a choice. You can keep it in the fridge or at room temperature. But, it will only be good for a certain amount of time after that first use or removal from the fridge.
Knowing these basic rules is the first step. Now let’s get into the details.
Refrigerator Storage for Semaglutide
Most Semaglutide products tell you to keep them in the fridge before you open them. This is the standard way to store them for a long time.
The Right Temperature for Semaglutide in the Fridge
The specific Semaglutide storage temperature fridge range is very important. It should be between 36°F and 46°F (2°C to 8°C). This temperature range is common for many medicines that need to be kept cold.
- Too Cold: Do not let Semaglutide freeze. Freezing can ruin the medicine. If Semaglutide freezes, you must throw it away, even if it thaws later.
- Too Warm (but still in fridge range): Keeping it slightly warmer within the fridge range (closer to 46°F) is okay. But staying within the 36°F to 46°F range is best.
- Fluctuating Temperatures: Try to keep the temperature steady. Avoid placing the pen in parts of the fridge where the temperature changes a lot. The door is often not the best spot. The back of the main shelf is usually more stable.
Checking your fridge temperature now and then is a good idea. You can use a simple fridge thermometer. This helps you make sure your Ozempic storage in fridge or Wegovy storage temperature fridge is correct.
Duration for Unopened Semaglutide in the Fridge
How long can an unopened Semaglutide pen stay good in the fridge? This is usually until the expiration date printed on the pen and the box. The manufacturer sets this date. It means the medicine is expected to be safe and work well until that date if it has been stored correctly the whole time. This includes keeping it continuously in the fridge within the right temperature range.
- Ozempic Storage in Fridge: Unopened Ozempic pens should be stored in the refrigerator (36°F to 46°F or 2°C to 8°C). They are good until the expiration date on the label.
- Wegovy Fridge Storage Duration: Unopened Wegovy pens also need to be stored in the refrigerator (36°F to 46°F or 2°C to 8°C). Like Ozempic, they are good until the expiration date if kept cold the entire time.
- Unopened Semaglutide Storage Fridge: For any Semaglutide product that needs refrigeration before use, the rule is generally to keep it in the fridge until its printed expiration date.
Always check the date on your medicine package. This is your main guide for how long to keep an unopened pen in the fridge.
Duration for Opened (In-Use) Semaglutide in the Fridge
What happens once you start using a Semaglutide pen? Or if you take an unopened pen out of the fridge for the first time? The clock starts ticking.
Once a pen is in use, the storage time changes. The good news is you often have a choice: keep it in the fridge or keep it at room temperature. If you choose to keep it in the fridge, the clock for its lifespan outside of its original cold storage window still starts.
Here’s a general idea for Semaglutide injectable pens (like Ozempic and Wegovy):
- How Long is Ozempic Pen Good in Fridge After First Use/Removal: After the first use, or if an unopened pen is removed from the fridge, it can be kept for a specific time period. For Ozempic, this period is usually 56 days. During these 56 days, it can be stored either in the fridge (36°F to 46°F) or at room temperature (up to 86°F or 30°C). You do not need to put it back in the fridge between uses if you prefer to keep it at room temp within its allowed time. However, if you do put it back in the fridge, it must stay within that 56-day window from the first time it left the cold or was first used.
- Opened Semaglutide Pen Fridge Storage: Once opened, a Semaglutide pen has a limited lifespan, typically counted from the first use or first removal from the fridge. If you choose to store it in the fridge during this period, it must stay within the 36°F to 46°F range. The total time it is good for is usually around 56 days, regardless of whether it’s in the fridge or at room temperature during that time.
- Wegovy Fridge Storage Duration (Opened): Similar to Ozempic, once you start using a Wegovy pen (or take a new pen out of the fridge), it is typically good for 28 days. During this 28-day period, you can store it either in the fridge (36°F to 46°F) or at room temperature (up to 86°F or 30°C). Again, if you keep it in the fridge during this time, the 28-day limit from the first use/removal still applies.
It is crucial to note the difference in duration between Ozempic (56 days) and Wegovy (28 days) once the pen is in use or removed from the fridge. Always check the specific instructions for your prescription, as these times can sometimes vary based on the specific product form or packaging.
Ozempic Storage Guidelines Fridge
Let’s look more closely at Ozempic. The official Ozempic storage guidelines fridge state that unopened pens should be stored in the refrigerator at 36°F to 46°F (2°C to 8°C). Keep them in the original carton to protect them from light. Do not freeze Ozempic.
Once you start using an Ozempic pen, or take a new pen out of the fridge for the first time, it is good for 56 days. During these 56 days, you can store the pen either in the refrigerator (36°F to 46°F) or at room temperature (up to 86°F or 30°C). Write the date you first used the pen on the label or box. This helps you remember when the 56 days are up. After 56 days, throw the pen away, even if there is medicine left.
Wegovy Storage Temperature Fridge
For Wegovy, the Wegovy storage temperature fridge rule for unopened pens is also 36°F to 46°F (2°C to 8°C). Keep unopened pens in the carton in the fridge until you are ready to use them. Freezing Wegovy will ruin it, so never freeze it.
Once you use a Wegovy pen for the first time, or take an unopened pen out of the fridge, it is good for 28 days. During this 28-day period, you can store it either in the fridge (36°F to 46°F) or at room temperature (up to 86°F or 30°C). Just like with Ozempic, mark the date you started using it. Throw away the pen after 28 days, even if it still has medicine.
Room Temperature Storage for Semaglutide
You now know that once a Semaglutide pen is in use (or taken out of the fridge), you usually have the option to store it at room temperature for a limited time.
Semaglutide Room Temperature Storage Limit
The Semaglutide room temperature storage limit is key for in-use pens.
- For Ozempic: Up to 86°F (30°C) for a total of 56 days from the first use or first removal from the fridge.
- For Wegovy: Up to 86°F (30°C) for a total of 28 days from the first use or first removal from the fridge.
These time limits (56 days for Ozempic, 28 days for Wegovy) apply whether the pen is kept at room temperature or put back in the fridge during that period. The total time it is good for outside of the original cold storage window is fixed.
It is important to stay below the maximum room temperature limit (86°F or 30°C). Do not leave your pen in a hot car. Do not leave it in direct sunlight. High heat can damage the medicine quickly.
Semaglutide Expiration Date and Storage
The Semaglutide expiration date fridge means the date the medicine is good until if stored continuously in the fridge within the right temperature range (36°F to 46°F) from when it was made until you use it.
- Unopened: The expiration date on the box and pen label applies when stored properly in the fridge the whole time.
- Opened/In Use: Once you start using a pen, or take it out of the fridge, the expiration date on the box no longer matters for that specific pen. Instead, the pen is good for the in-use period (56 days for Ozempic, 28 days for Wegovy), as long as it’s kept within the allowed temperature ranges (either fridge or room temp up to 86°F) during that time. You must throw the pen away after this period, even if the original expiration date on the box is later.
Think of it this way: The printed expiration date is for long-term cold storage of an unopened pen. The shorter time limit (56 or 28 days) starts the moment the pen leaves its initial cold storage or is first used, whichever comes first.
Grasping the Different Storage Phases
It helps to think of Semaglutide storage in phases:
Phase 1: Unopened Storage Before First Use
- Location: Refrigerator.
- Temperature: 36°F to 46°F (2°C to 8°C).
- Duration: Until the expiration date printed on the pen/box.
- Protection: Keep in original carton to protect from light. Do not freeze.
Phase 2: In-Use Storage (After First Use or First Removal from Fridge)
- Location: Can be stored either in the refrigerator or at room temperature.
- Temperature: Refrigerator (36°F to 46°F or 2°C to 8°C) OR Room Temperature (up to 86°F or 30°C). Do not expose to temperatures above 86°F.
- Duration:
- Ozempic: 56 days from the first use or first removal from the fridge.
- Wegovy: 28 days from the first use or first removal from the fridge.
- Protection: Protect from light and excessive heat. Do not put needles on the pen for storage. Do not freeze.
Once Phase 2 begins for a pen, the Phase 1 rules no longer apply to that specific pen.
What Happens If Storage Rules Are Not Followed?
Not storing Semaglutide correctly can make it less effective. The medicine might not lower your blood sugar or help with weight as much as it should. This is because the Semaglutide molecule can break down at the wrong temperatures.
- Freezing: Freezing is very bad. It can cause the protein structure to break down in a way that makes the medicine useless or potentially harmful. If your pen freezes, do not use it. Throw it away.
- Excessive Heat (Above 86°F/30°C): High heat can also quickly break down the medicine. Leaving a pen in a hot car means you should probably not use it.
- Staying Out Too Long (Beyond 56 or 28 days): Even if the temperature is okay, using a pen past its in-use time limit means the medicine may have lost some strength or stability over time.
Always follow the storage instructions carefully. It is the best way to make sure your medicine is safe and works as intended.
Deciphering Storage for Travel
Traveling with Semaglutide needs careful planning to maintain the correct temperature.
- Before First Use (Needs Fridge): If you are traveling with an unopened pen that needs to stay refrigerated, use an insulated bag or cooler with ice packs. Make sure the pen does not touch the ice packs directly, as this could freeze it. Wrap it in cloth or use a separate container inside the cooler. The goal is to keep it between 36°F and 46°F.
- In-Use Pen (Can Be Room Temp): If you are traveling with a pen you have already started using (or that has been out of the fridge for less than its 56 or 28-day limit), you can usually keep it at room temperature (below 86°F). Carry it in a small bag or case to protect it. Avoid leaving it in hot places like windowsills or cars.
- Airport Security: Semaglutide is a prescription medicine. Carry it in its original box with your prescription label if possible. You are allowed to carry necessary medical supplies, including syringes and pens, onto planes. Having a letter from your doctor explaining your need for injectable medicine can be helpful, but is often not necessary for domestic travel with standard supplies. Check TSA guidelines for specific details on traveling with medicine.
The key for travel is to protect the pen from extreme temperatures (freezing and high heat) and direct light.
Checking Your Semaglutide Before Use
Even if you think you stored your pen correctly, it is a good idea to check the medicine before you inject it.
Semaglutide solution should look clear and colorless. Do not use it if:
- It looks cloudy.
- It has color.
- It has small pieces floating in it (particles).
- It looks different from how it normally does.
These changes could mean the medicine is no longer good. If you see any of these things, do not use the pen. Get a new one.
Table Summarizing Semaglutide Storage
Here is a quick table to help you remember the main rules for injectable Semaglutide (like Ozempic and Wegovy). Always check the specific instructions that come with your medicine, as there can be small differences.
| Storage Phase | Condition | Temperature Range | Duration | Notes |
|---|---|---|---|---|
| Unopened Pens | Before First Use | Fridge: 36°F to 46°F (2°C to 8°C) | Until printed expiration date | MUST be kept cold. Protect from light. DO NOT FREEZE. |
| In-Use Pens | After First Use | Fridge: 36°F to 46°F (2°C to 8°C) | See Below (time starts on first use/removal) | Keep away from light & heat. Remove needle cap for storage. |
| OR | Room Temp: Up to 86°F (30°C) | See Below (time starts on first use/removal) | Keep away from light & heat. Remove needle cap for storage. | |
| In-Use Duration | Ozempic (Opened) | Fridge (36-46°F) OR Room Temp (up to 86°F) | 56 days from FIRST use/removal from fridge | Throw away after 56 days, even if medicine is left. |
| In-Use Duration | Wegovy (Opened) | Fridge (36-46°F) OR Room Temp (up to 86°F) | 28 days from FIRST use/removal from fridge | Throw away after 28 days, even if medicine is left. |
Note: ‘First use/removal from fridge’ means the clock starts the moment you either inject from the pen for the first time OR take a new, unopened pen out of the fridge to prepare for use, whichever happens first.
Frequently Asked Questions About Semaglutide Storage
h4 What should I do if my Semaglutide froze?
If your Semaglutide pen freezes, do not use it. Freezing damages the medicine. Throw it away and get a new pen. Even if it thaws, it is not safe or effective to use.
h4 Can I put my Semaglutide pen back in the fridge after keeping it at room temperature?
Yes, for in-use pens (after the first use or first removal from the fridge), you can store them either in the fridge (36°F to 46°F) or at room temperature (up to 86°F) within their allowed time period (56 days for Ozempic, 28 days for Wegovy). Putting it back in the fridge during this time is fine, but it does not reset the clock on the 56 or 28-day limit.
h4 How can I remember when my opened Semaglutide pen expires?
Write the date you first used the pen on the pen label or the box. Then count 56 days (for Ozempic) or 28 days (for Wegovy) forward. That is the date you need to throw it away. Setting a reminder on your phone can also be helpful.
h4 Can I store opened pens without the needle cap?
Yes, the needle should be removed after each injection and properly disposed of. The pen cap should be put back on the pen. Do not store the pen with the needle attached. This helps prevent leaks, blocks the needle from getting clogged, and keeps the medicine sterile.
h4 Is it okay if my Semaglutide was left out of the fridge for a few hours?
An unopened pen that needs refrigeration should ideally stay cold all the time. However, some brief time out of the fridge might be acceptable depending on the temperature it was exposed to and for how long. The manufacturer’s instructions for in-use pens give a limit of up to 86°F (30°C). If your unopened pen was exposed to temperatures above 46°F but below 86°F for a short time (like a few hours during transport home from the pharmacy), it might still be okay. But if it was exposed to high heat or left out for many hours or days, its quality is likely affected. If you are unsure, it is safest to ask your pharmacist or the manufacturer for advice.
h4 Does Semaglutide need to be protected from light?
Yes, both unopened and in-use pens should be protected from light. Keep them in their original carton until needed. Store them away from direct sunlight.
h4 What is the difference between Ozempic storage in fridge and Wegovy fridge storage?
The main rules are similar for unopened pens: store in the fridge (36°F to 46°F) until the expiration date. The key difference is the length of time they are good for after the first use or first removal from the fridge. Ozempic is typically good for 56 days, while Wegovy is typically good for 28 days. Both can be stored either in the fridge or at room temperature (up to 86°F) during this in-use period.
h4 Where can I find the official Semaglutide storage guidelines?
The official storage guidelines are printed on the medicine box, the pen label, and the patient information leaflet that comes with your prescription. Your pharmacist is also a great resource for storage questions.
