Quick answer: Yes, semaglutide does expire. Your medication should have a printed expiration date on the pen or packaging. Using it past that date, or leaving it unrefrigerated for too long, can reduce its effectiveness. Proper storage and checking the expiration date help ensure every dose works as intended.

In this article, we'll break down how long semaglutide stays good, cover what can happen if you use it after it expires, and share practical tips to help you keep every dose potent and avoid wasting your medication.

Does Semaglutide Expire?
Yes, semaglutide does expire.
It is the key ingredient in two well-known medications: Wegovy for weight management and Ozempic, which is used to control blood sugar in type 2 diabetes and is also often prescribed for weight loss.
Like insulin and other injectable medications, semaglutide is a biological medication that is sensitive to time and temperature. Once it's past its expiration date, the medication can begin to break down.
When does semaglutide expire?
Whether it's Ozempic or Wegovy, each pen has a printed expiration date on the box and the pen itself, and that date matters. After it passes, the medication may lose potency or, in rare cases, be unsafe to use.
Proper storage is key. Semaglutide should be kept refrigerated at 36-46°F (2-8°C) before first use.
Does semaglutide expire after 28 days?
Once you start using a pen, how long it can stay at room temperature (below 77°F or 25°C) depends on the brand.
- Wegovy: Good at room temperature for up to 28 days.
- Ozempic: Good at room temperature for up to 56 days.
Compounded semaglutide vials can vary. Their room-temperature shelf life is often shorter and depends on the specific formulation and any preservatives used, so always follow the instructions provided by the pharmacy or manufacturer.
Keeping these timelines straight is key to getting the full benefit of your medication. If you travel or need to carry your doses with you, a mini medical fridge or insulated cooling pouch can help maintain the right temperature and prevent accidental spoilage.

What Happens If You Use Expired Semaglutide
Using expired semaglutide isn't ideal.
Over time, the chemical composition can break down, making the injection less effective. This could result in poor blood sugar control or reduced weight loss effects.
So, while using expired semaglutide usually isn't dangerous, it can lead to wasted doses, stalled progress, and the extra expense of replacing medication that no longer works well.
Because there's no guarantee an expired dose will perform as intended, it's important to check expiration dates and store your pens properly.
🚨 Important tip: If you notice anything unusual after using it, like swelling at the injection site or unexpected side effects, contact your healthcare provider immediately.
Expired semaglutide: signs to watch for
If you're not sure whether your semaglutide is still good, there are a few things you can check to help determine its quality:
- Appearance: The solution should be clear and colorless. If it looks cloudy, has particles, or has changed color, don't use it.
- Storage History: If it's been left out of the fridge too long or stored improperly, it may be less effective, even if the date hasn't passed.
- Smell: While semaglutide generally doesn't have a strong odor, any unusual smell could be a warning sign.
When in doubt, it's better to discard the pen than risk using something that might not be effective.

What to do if you accidentally took expired semaglutide
If you've accidentally used expired semaglutide, don't stress. It happens more often than you might think. In most cases, it isn't dangerous, but the medication may not work as effectively as it should.
If you're using semaglutide for diabetes management, keep a closer eye on your blood sugar over the next day or two, and reach out to your healthcare provider. They can advise if any follow-up steps are needed or whether your next dose should be adjusted.
Mix-ups are easy to make, especially when you're managing multiple medications or traveling. One way to make life a little easier and reduce the risk of using expired doses is to use a reliable storage solution.

Tips to Make Sure You Never Use Expired Semaglutide
Staying on top of expiration dates doesn't have to be stressful. A few simple habits can help you avoid using a dose that's past its prime:
✅ Set reminders: Add the expiration date and the "first-use" date to your phone calendar so you'll know exactly when each pen should be discarded.
✅ Label your pens: Use a small sticker or piece of tape to mark when you first took the pen out of the fridge.
✅ Store it properly: Consistent, cool temperatures help the medication stay potent until its printed expiration date. A mini medical fridge is great for home or travel, and insulated cooling pouches keep doses safe on the go.
✅ Avoid temperature swings: Repeatedly moving pens between the fridge and warm environments can shorten their shelf life, even before the official expiration date.
✅ Check before every use: Make it a habit to glance at the expiration date and inspect the medication for changes in color or particles.
