Ozempic (semaglutide) is a once-weekly injectable medication that is prescribed to patients with type 2 diabetes and is approved to improve glycemic control in adults with type 2 diabetes and to reduce certain cardiovascular risk and kidney outcomes in those with chronic kidney disease. Some patients also report losing weight while using it. This medication has specific requirements to help make sure the medication stays safe to use and maintains its full effectiveness. These storage instructions also help make sure the medication does not have a shortened shelf-life. Proper storage is extremely important and has led many patients to wonder whether or not this medication needs to be refrigerated.

Should Ozempic Be Kept in the Refrigerator?
This medication needs to be refrigerated until the patient uses it for the first time. That means keeping it refrigerated between 36°F and 46°F. This is the equivalent of 2°C to 8°C. Keeping the medication at this temperature helps to preserve the integrity of the medication and make sure it does not lose any of its potency. New Ozempic pens usually remain effective until their expiration date as long as they are stored properly. It is important to make sure that Ozempic is not accidentally frozen. It should be discarded if this is the case—as this can damage the integrity of the medication.
Is Refrigeration Needed for Ozempic After First Use?
Patients have a couple of different choices for how to store their Ozempic after it has been used for the first time. The first option is to return the pen to the refrigerator and continue storing it between 36°F and 46°F. Patients can also store this medication at room temperature—between 59ºF and 86ºF—after it has been used for the first time. This medication should be disposed of after 56 days (or 8 weeks) regardless of which option is chosen. This applies even if there is medication remaining in the pen. It is also important to make sure the medication is stored with the cap on and protected from light.
Importance of Refrigerating Ozempic Before Initial Use
Not refrigerating Ozempic before the first injection from the pen may reduce how well it works. This means it may not help patients manage their blood sugar levels properly and can be unsafe to use. The refrigeration is what makes the medication last until its intended expiration date. Even leaving the medication out just a few days before use can degrade its effects—including its effects on weight loss and blood sugar management.
Leaving this medication out before first use is unsafe in most cases. However, the medication may be left out before first use for about 30 minutes if the patient does not want to make the injection cold. Patients who are unsure of how long the medication has been left out before using it should contact their pharmacist before using it for additional guidance or possible replacements.
Room Temperature Storage Limits for Ozempic
Pens that have not been opened yet must be refrigerated and kept at a temperature between 36°F and 46°F until they are first used. The only exception is letting the medication warm up a little—for up to 30 minutes—right before it is used to avoid injecting cold medication.
Pens that have been used should not be used if they exceed 56 days at room temperature. Patients should still keep this medication under 86°F and avoid direct sunlight. Pens—whether opened or unopened—should never be stored in extreme hot or cold temperatures. Medication that gets too hot or freezes may be unsafe to use. Patients who are traveling and need to be more careful can use insulated bags to store their pens in. These bags may make it easier for them to regulate the temperature the medication is being stored in.
Signs Ozempic May Have Been Stored Improperly
There are some signs that could indicate that the medication within an Ozempic pen has gone bad. These pens may be unsafe to use if they are no longer clear and colorless. Floating particles in the medication could also indicate that it has gone bad. Ozempic should be completely clear and particle-free.
The medication may also have gone bad if it had become too warm—such as if it had been mistakenly left out in a hot car or feels warm to the touch—or if it had become frozen. Pens should be discarded and replaced if they have any of these visual changes or have been kept in extreme temperatures. Using this medication is unsafe and the effectiveness of the medication may be altered.
Storage Tips When Traveling With Ozempic
General Principles
Ozempic is a temperature-sensitive medication. Keeping it in temperatures that are too warm or too cold can damage it and make it unsafe for patients to use. Unopened pens have more temperature restrictions. These pens must be refrigerated until used for the first time. These pens may then be put back in the refrigerator or stored at room temperature after they have been used for the first time. Opened pens kept in either temperature can be used for up to 56 days after it has been first opened.
Pens should never be frozen or stored above 86°F. They should also never be out in direct sunlight. This may be more challenging to do for patients who are traveling or using their medications away from home. This is why it is extra important for these patients to make sure they have storage solutions planned first.
Short Trips (Day Travel)
Extra caution should be taken even during short day trips. It may be beneficial for patients to keep their medication stored in either an insulated bag or a travel cooler to stop it from being exposed to extreme temperature changes. Cooling packs can also be added to keep the medication cool until it can be safely stored at home or in the refrigerator. However, patients will need to make sure that the cooling packs or ice do not make direct contact with the pen. It is best to wrap these in a cloth first to avoid accidentally freezing the medication.
Patients traveling with their medication should also make sure the container they are carrying it in is with them and not left behind in their vehicle. This limits the possibilities for uncontrolled temperature changes. For example, leaving the medication in a hot car or in direct sunlight may cause the medication to become too warm.
Air Travel
Those who are taking Ozempic with them during air travel should make sure to pack their pens in their carry-on. This reduces the chances of the medication becoming lost or damaged. It is also possible for airline cargo to become too hot or too cold. Medical travel cases containing temperature control gel packs can help make regulating the temperature of this medication easier during travel. However, patients deciding to bring these gel packs with them will need to declare them as medically necessary too. These gel packs will still be allowed in reasonable quantities, but may need to be inspected.
Passengers should make sure to declare their Ozempic pens to the TSA when going through security. These medications are often required to be removed from carry-on luggage when the patient is going through checkpoints so that it is easier for agents to scan them separately. Patients will also need to make sure that their medication is either clearly labeled or still being stored in its original packaging so that it is easy to identify. The same goes for all other needles and supplies being used. Patients should also make sure they have a copy of their prescription on them—or a doctor’s note—in case any questions about the medication pop up during routine security checks.
Long Travel (Overnight or Multi-Day)
Patients who are traveling for more than one day will need to take extra steps to make sure their medication stays safe. Those carrying unopened pens should store them in a small travel refrigerator or portable cooler that can keep a steady temperature between 36°F and 46°F. Travel coolers with rechargeable batteries or USB-powered units may be especially useful for longer trips where refrigeration is not guaranteed.
Storage is a little less complicated for pens that have already been opened. These pens may be kept safely at room temperature for up to 56 days—as long as the temperature does not go above 86°F (30°C). However, patients still need to be careful not to leave them in hot environments—like hot cars, in direct sunlight, or areas with little ventilation. They should also not have the medication exposed to heat in certain hot and humid areas—like beaches or saunas. The exposure to heat may reduce its effectiveness
International Travel
International travel with Ozempic requires additional planning. Different countries often have their own requirements for bringing injectable drugs across borders. Patients should check these regulations in advance to avoid problems at customs. Bringing a doctor’s note or a printed copy of the prescription is strongly recommended. This note should clearly explain the patient’s condition, the name of the medication, and the prescribed dosage. Keeping pens in their original packaging also helps customs officials identify the medication quickly.
Patients should carry enough supplies for their entire trip. This includes extra needles and alcohol swabs. This also includes a safe way to dispose of used needles (if a standard sharps container is not available). A small travel-approved sharps container or a sturdy sealed container can be used temporarily. Carrying an extra pen or two as a backup is also wise in case of loss/damage, or unexpected delays in returning home. However, patients should make sure they will have access to proper refrigeration at their destination for unopened pens.
Tips for Safe Storage at Home
Patients storing their medication at home should always remember to:
- Keep the medication capped between uses.
- Store the medication away from any direct light or heating/cooling elements.
- Put the medication somewhere safe and out of reach for children or pets.
- Use a thermometer to monitor temperatures in storage areas—like refrigerators—that fluctuate.
- Avoid storing the medication within the door of the refrigerator. Temperatures may rise there more suddenly when the door is open.
- Medication stored in the refrigerator should be placed on lower or middle shelves where it is further from internal fans/cooling vents or drawers for frozen items. The back wall of the refrigerator should also be avoided.
- Medication kept out of the fridge should be placed in a cool and dry place.
Risks and Side Effects of Baby Aspirin
There are multiple risks patients should be aware of when taking baby aspirin.
- This medication causes an increased bleeding risk (including increased risk of bleeding in the stomach or bruising)
- May cause a hemorrhagic stroke if it causes bleeding in the brain
- Taking this medication (especially on an empty stomach) can cause stomach/GI irritation and ulcers over time
- Not recommended for those with conditions that increase bleeding risk or those with allergic reactions to the medication
Aspirin should never be taken without guidance from a medical professional.
How to Safely Use Ozempic (Step-by-Step)
- Step 1
Handwashing and collecting all required supplies should be done prior to injection. This includes the pen itself and a fresh needle. It also includes an alcohol swab and a sharps container. - Step 2
Check to make sure the pen is safe to use. This includes double-checking the label and making sure the medication inside is still clear and colorless. - Step 3
Attach a new needle. This includes teasing off the paper and pushing and turning the needle until it is securely in place. Patients will also need to prime the pen if this is the first time it is being used. This includes performing a flow check. This can be done by turning the dose counter until the flow check symbol appears. The patient will then have to hold the dose button until the counter displays “0” and a drop appears at the tip of the pen. - Step 4
Use the dose selector on the pen to choose the appropriate amount of medication. - Step 5
Choose an injection site—this may be the stomach, thigh, or upper arm—and clean the area thoroughly with alcohol. - Step 6
Gently pinch the skin and insert the needle at a 90° angle. Press and hold the button until the dose counter displays zero. Keep the needle in the skin and count to six at a slow pace before removing. - Step 7
Safely dispose of the needle by putting it into a sharps container and recap the pen. It should then be safely stored away until next use or disposed of properly if it is the last dose.
Safety Reminder
Patients should rotate injection sites each week to prevent skin irritation or the formation of lumps. The medication should never be injected into irritated skin and needles should never be reused.
The Bottom Line
Ozempic should be kept in the refrigerator until the patient begins using the pen. However, patients may store the medication at room temperature for up to 56 days after it has already been opened. Using proper storage techniques is how patients can make sure their medication maintains its effectiveness and is safe to use.

FAQs
Can a used Ozempic pen be kept cold again in the fridge?
Patients may choose to put their medication back in the refrigerator after it has been first used (as long as it is still within the 56-day window). The medication must still be kept under 86°F.
What happens if Ozempic freezes?
Frozen Ozempic should never be used. Freezing permanently damages the medication. This damage does not go away after the medication is thawed. Frozen pens should be discarded and replaced.
Can Ozempic be left out overnight?
Leaving it out overnight at normal room temperature (below 86°F) is fine if the pen has already been used and is within the 56-day window. However, any pens that have not yet been opened must always be kept refrigerated (36-46°F). If an unopened pen is left unrefrigerated, patients should not use it until they confirm the temperature/duration with their pharmacist or Novo Nordisk. If the product was frozen or kept above 86°F (30°C), it should no longer be used and must be discarded. If exposure is unknown, very warm, or the pen was frozen, discard.
How do I travel with Ozempic safely?
Patients should keep their pens in their carry-on bag (never checked luggage) if flying and use insulated medical cases or travel coolers with gel packs. Patients should carry their prescription or doctor’s note with them and make sure the medication stays out of direct heat or areas where it could freeze. The medication—and any additional tools used with it—should be kept in their original packaging or be carefully labeled.
Does refrigeration affect how Ozempic works?
Proper refrigeration before first use makes sure that the medication stays potent up until its expiration date. The medication can degrade early and may not control blood sugar as effectively if it is not refrigerated before the pen’s first use.
Is it safe to return an Ozempic pen to the refrigerator once it has been at room temperature?
Patients can switch between refrigerator and room temperature storage as needed after the pen has been used for the first time. They will still have to be careful not to exceed the 56-day usage window.
What signs indicate an Ozempic pen is safe to use?
The medication in an Ozempic pen should remain clear and colorless with no visible particles. If the liquid looks cloudy or discolored—or if the pen has been exposed to extreme heat or freezing—it should be thrown away and replaced.
How do I inject Ozempic correctly?
Patients should wash their hands and attach a new needle. The medication should be checked to make sure that it is clear before dialing the prescribed dose and the patient should sanitize the injection area using an alcohol swab. The needle is then inserted at a 90° angle and the button is pressed until the counter shows “0.” The button should then be held for 6 seconds before removing the needle. Needles should never be reused and must be discarded in a sharps container after use. The pen should then be recapped and stored properly for future use.
