Yes, Dupixent is self-administered at home. It’s a subcutaneous injection (just under the skin) that comes in pre-filled syringes and pre-filled pens designed for patients or caregivers to use without medical staff present. Your first injection does need to happen at your doctor’s office so you can be trained on proper technique, but after that, you handle it on your own.
Training Before Your First Injection
You cannot simply fill the prescription and start injecting at home right away. Your first injection training must come from your doctor’s office, where a healthcare provider walks you through the full process: selecting an injection site, preparing the device, performing the injection, and disposing of the syringe or pen safely. Once your provider is satisfied you (or your caregiver) can do it correctly, every injection after that happens at home on your own schedule.
Pre-Filled Pen vs. Pre-Filled Syringe
Dupixent comes in two device types. The pre-filled pen is an auto-injector: you press it against your skin, click a button, and the device delivers the medication automatically. The pre-filled syringe is manual, meaning you push the plunger yourself to control the speed of the injection. Both devices come ready to use with no mixing or measuring required.
The choice between pen and syringe often comes down to personal comfort. Some people prefer the pen because it hides the needle and requires fewer steps. Others prefer the syringe because they can control how fast the medication goes in, which can reduce stinging. Your doctor can help you decide, and you can switch between devices if one isn’t working for you.
Where to Inject
The recommended injection sites are the front of your thighs and your abdomen (at least two inches away from your navel). The upper arm is also an option, but only if someone else is giving you the injection, since it’s difficult to reach and pinch the skin properly on your own. You should rotate your injection site each time and avoid areas where the skin is tender, bruised, damaged, or hardened.
How to Prepare the Injection
Dupixent is stored in the refrigerator between 36°F and 46°F. Before injecting, you need to take the device out and let it warm to room temperature on a flat surface. The wait time depends on the dose:
- 100 mg or 200 mg devices: at least 30 minutes
- 300 mg devices: at least 45 minutes
Don’t try to speed this up with a microwave, hot water, or direct sunlight. Injecting cold medication is more likely to sting and may affect the drug.
Before injecting, check the liquid through the viewing window. It should be clear and colorless to pale yellow. A small air bubble is normal and not a concern. If the liquid looks cloudy, discolored, or has visible particles or flakes floating in it, don’t use that device.
Age Requirements for Children
Dupixent is approved for patients as young as 6 months, but self-administration has age limits. Patients 12 and older can inject themselves using either the pen or syringe, though they should still do so under the supervision of an adult. Children under 12 must have a caregiver perform every injection.
Storage at Home
Keep your Dupixent in the refrigerator until you’re ready to use it. If needed, you can store it at room temperature (up to 77°F) for a maximum of 14 days. This is useful for travel or situations where you don’t have refrigerator access. Any device that has been at room temperature for more than 14 days needs to be thrown away, even if it looks fine. Don’t put it back in the refrigerator to “reset” the clock.
What to Do If You Miss a Dose
If you miss your scheduled injection, you have a 7-day window to take it. Inject as soon as you remember within those 7 days, then continue with your original dosing schedule from there. If more than 7 days have passed since your missed dose, skip it entirely and wait for your next regularly scheduled injection. Don’t double up to make up for a missed dose.
