<<Disclaimer: Verify this information before applying it to your situation.>> Help....... need recommendations for Antihistamines safe for Celiacs. I'm apparently having some sort of an allergic reaction to something and I don't know what to do to relieve the itching. The skin on my entire body itches, from my head to my toes, and everything in between. I have no idea what has caused this. Any suggestions are welcome and appreciated; thank you. Ronnie Herig
