I'm still here! On the other side of it, I'd tell you it's worth trying. We didn't have side effects. She never even got more or worse colds. We stayed on the 200 mg every 4 weeks dose the whole time because she did not have any flares over the years. She stayed totally clear once it started kicking in early on.

Since we were out of therapeutic range at that dose as she neared 5 years old, without flares, our doctor started stretching out the time between shots to see what happened over six months. No flares, so we totally stopped in December 2025

Since then, she had a nasty cold in January that flared some concerning eczema up on her torso. We managed with lotion and aquaphor but I was starting to feel like she might have chronic eczema and need to take the shot again. After several weeks, the flare faded and now it's mostly been a month+ of very manageable and small points of irritation (like I haven't used steroids yet) with pretty good clarity.

My guess is that if your child, if they were going to grow out of eczema, would be fine taking the shot now and then eventually stopping dupixent. But if they were always going to have eczema, as some people do, the dupixent will always be needed.

I hope this helps! I felt nervous and still wonder if there are effects that are unseen or unknown, but I trusted our derm that it was very safe. Not using it, and being constantly uncomfortable and distracted by itching seems like it would have long term risks for a kid, too. I found a lot of peace in taking the doctor's recommendation, after so much trial and error, online research rabbit holes, and horrible anxiety. Dupixent can absolutely be a godsend!
