<<Disclaimer: Verify this information before applying it to your situation.>> I haven't yet received my Stokes Pharmacy Guide and am supposed to have a prescription filled. If someone out there could help I would appreciate it. I need to know if Zephrex (either CA or LA, can't read Dr's writing) is gluten free. It is a super duper antihistimine. Any help would be greatly appreciated. kris wichita,ks
