From everything I’ve read and heard recently, it would be cromolyn sodium that would do the trick.
I found out it’s a mast cell stabilizer.
Okay I bought the generic Zantac...wish I knew how much the mice were given so I could take equivalent dose. Cromolyn sodium I find as Nasalcrom—is that the only method of dosage? I worry about a nasal spray (thinking of Dristan) and being addicted.
