For GI-based mast cell issues, oral Sodium Cromoglycate (aka “Nalcrom”) in capsule or liquid form seems to be the best thing. The dose I take is 600mg per day (6 capsules) and I’ve seen other people on 8 per day. For me it helped a lot with nausea, diarrhoea, bloating, and reflux.
The main drawback in my case is that it’s fairly expensive for me but that will depend on your insurance situation! Everything I’ve read seems to indicate it’s a quite safe medication to take.
Thanks, Jeshyr! We used the capsules for a while, too (had them made from a formulating pharmacy). The only drawback is that the contents of the capsule are supposed to be mixed with water before drinking. Ugh. That stuff is hard to dissolve! Most of it ended up sticking to the sides of the glass, we noticed. Ketotifen is a small pill available out of Canada (and other countries) — it’s taken twice a day. Most doctors can order that for you, too. Another option… 🙂
