How did you start the cromolyn? Did you work you’re way up to the required dose? (1 vial 30 minutes before a meal for a week and so on?)
I started seeing a positive difference in my son at week/ vial 4 (100mg vials). I’m on week/ vial 3 (100 mg vials) and am starting to notice small improvements. Dr. Castells told us that it will take 3-6 months to see it’s full effects.
If you think the rash is from the cromolyn you should probably discontinue it and check with your doctor. There are other mast cell stabilizers like Ketotifen.
Sorry you’re going through all of this.
