I used to have severe environmental allergies to cats, dogs, and the outdoors. As I kid, I woke up crying most mornings because of my allergies, and I would occasionally wake up with croup and difficulty breathing. I even had to be taken the hospital once.
Anyways, I cried enough that my mother found and enrolled me in a study for an experimental treatment called sublingual immunotherapy (SLIT). For the next two years I took under-the-tongue drops, and I presume the drops were formulated with small amounts of the allergens I was reactive to.
My allergies have been nearly non-existent since then.
I’m sharing this post because I keep telling people about sublingual immunotherapy and they’re very surprised. No one seems to know about this treatment! I’m mad about this.
Maybe my improvement was unusual? I don’t know. A few random studies. Please share additional information in the comments.
To be clear, I still have a few mild symptoms:
- If I pet a dog and then rub my eyes, my eyes get slightly itchy.
- If a dog licks me, I get mild hives in that area.
But that’s all! (And I haven’t observed any side effects, either.)
FWIW, I might also go back on sublingual immunotherapy at some point so I can pet dogs without worry. (Because maybe my treatment was stopped too soon?)
Other details:
- My mother says the particular drops I took costed $25 a week. They weren’t FDA approved, but they were still available for purchase.
- From a quick brief search, I found a few that sell sublingual immunotherapy in the US: Wyndly, Curex, and Quello. I looked a few months ago and I couldn’t find any significant reason to prefer one brand over the others. Please comment you have a recommendation.
- Note: SLIT has been available for longer in Europe than in the US, so the European brands might be better if you have access to them.
I was allergic to acarids when I was a child, and this caused me a severe asthma crisis when I was around 10. I live in France, and I got prescribed SLIT by the first allergy specialist my mother found, so I guess it's quite a common treatment there. I took it for more than 5 years, and now 8 years later I don't ever have any symptoms of allergy.
