Have you tried compounding pharmacy for antihistamines if she can’t tolerate supplements?
Yep -- the Cromolyn was compounded and she's now very reactive to it.
But antihistamines aren't really a solution and they only cover up your issues and will prevent you from knowing food triggers and other triggers.
She isn't going to be able to tolerate any RX as long as her gut is leaky. I need to solve her leaky gut.
