i found this the other day. Cheap enough to try. Seems like no rx needed. Shipping was $2.50 USPS
I didn't mean for gut. I wake up every morning with my nose stuffed up. This is new so maybe it's some mast cell in the sinus thing.From what I've read, it's not nearly as effective as oral GastroCrom.
Obviously, it isn't going to do much for gut histamine.
