Small air bubbles in Ozempic pens are normal and safe
It is common for small air bubbles to be present in an Ozempic pen, and it is safe to proceed with your injection. Unlike with intravenous (IV) injections, where a large amount of air entering the bloodstream can cause a serious condition called an air embolism, Ozempic is administered as a subcutaneous injection. This means the medication is delivered into the fatty tissue just under the skin, where small air bubbles are harmlessly absorbed by the body.
Subcutaneous vs. Intravenous Injections: A Comparison
To understand why air bubbles are not a concern for Ozempic, it's helpful to compare the two injection methods.
| Feature | Subcutaneous Injection (e.g., Ozempic) | Intravenous Injection (IV) |
|---|---|---|
| Injection Site | Fatty tissue beneath the skin | Directly into a vein |
| Needle Length | Short | Longer |
| Absorption | Slow, steady absorption by surrounding capillaries | Immediate entry into the bloodstream |
| Air Bubble Risk | Small bubbles are harmless and absorbed by the body | High risk; large amounts of air can be fatal if not removed |
| Common Use | Medications like insulin, heparin, and semaglutide (Ozempic) | Hospital procedures, chemotherapy, hydration |
Why do air bubbles appear in the Ozempic pen?
Air bubbles can form in your Ozempic pen for several reasons, including temperature changes, changes in ambient pressure, normal handling, and leaving the needle attached after an injection. These occurrences are typically part of a normal process.
The importance of priming a new pen
Priming a new Ozempic pen before its first use is essential to remove air from the needle and cartridge, ensuring an accurate dose. Priming only needs to be done once per new pen.
To prime your pen:
- Attach a new needle.
- Turn the dose selector to the flow check symbol.
- Hold the pen with the needle pointing up and gently tap it.
- Press and hold the dose button until the counter shows 0 and a drop appears at the needle tip.
- If no drop appears, repeat or try a new needle.
When to be concerned about an Ozempic bubble
While small air bubbles are not a concern, contact your healthcare provider or pharmacy if you observe large or persistent air bubbles that seem to affect the medication quantity, if the medication is cloudy or discolored, or if the pen is damaged.
Ozempic injection technique and safety tips
Proper injection technique ensures safety and accuracy:
- Rotate injection sites (abdomen, thigh, upper arm) to avoid lumps.
- Insert the needle fully to prevent medication pooling.
- Hold the dose button until the counter reaches 0 and for an additional 6 seconds.
- Use a new needle for each injection and dispose of it in a sharps container.
- Store unused pens in the refrigerator; used pens can be at room temperature for up to 56 days.
Conclusion
Small air bubbles are a normal and harmless aspect of using an Ozempic pen for subcutaneous injections. Priming a new pen as directed by the manufacturer ensures accurate dosing. Proper injection technique and site rotation are also important for safe medication administration. If you have concerns about large bubbles, changes in medication appearance, or a damaged pen, always seek advice from your healthcare provider or pharmacist.

Frequently Asked Questions
Is it harmful to inject a small air bubble with Ozempic?
No, injecting a small air bubble with Ozempic is not harmful. The medication is injected subcutaneously, and the body safely absorbs tiny air pockets without any risk of an air embolism.
Can an air bubble affect my dose of Ozempic?
A very large air bubble could potentially displace a small amount of medication, which might result in a slightly lower dose. However, following the proper priming steps for a new pen helps prevent this by expelling excess air before your first injection.
What is pen priming, and do I need to do it every time?
Priming is the process of expelling air from a new pen and confirming it is working correctly. You only need to prime a new Ozempic pen once, before the very first dose from that specific pen.
My new Ozempic pen has an air bubble. Should I prime it?
Yes, you should always prime a new Ozempic pen before its first use. Priming ensures that any air is removed from the needle and cartridge, confirming the pen is ready to deliver a full dose.
Why did a bubble form under my skin after an injection?
A bump or "bubble" under the skin after an injection is different from an air bubble inside the pen. It can happen if the needle isn't inserted fully, causing medication to pool just under the skin. This is usually temporary and harmless.
When should I contact my doctor about an air bubble in my Ozempic pen?
You should contact your healthcare provider if you notice a very large air bubble that prevents you from injecting the medication, if the pen is damaged, or if the liquid is cloudy, discolored, or contains particles.
Can air bubbles in the pen be caused by cold temperatures?
Yes, moving the pen from a cold environment (like the refrigerator) to room temperature can cause the liquid to expand and may result in the formation of air bubbles.
What is an air embolism, and is it a risk with Ozempic?
An air embolism is a serious condition where a large amount of air enters the bloodstream, but this is a risk associated with intravenous (IV) injections, not subcutaneous ones like Ozempic. The amount of air involved in a subcutaneous injection is too small to cause harm.
