<<Disclaimer: Verify this information before applying it to your situation.>> Hi All! Thanks to all who responded to my Claritin D question. I received several responses. Everyone said it was GF and had used it without problems. My pharmacist called the company and they said they only use corn starch of the finest pharmaceutical grade. Though they didn't exactly say it was GF, my pharmacist felt I could surmise that it was and she thought the company was saying that since it was finest US Pharmaceutical grade, that there was almost zero chance of contamination. One person advised drinking lots of water as it dries you out. Another person suggested using an over-the-counter med called Nasalcrom instead. I have used the Claritin D without any noticeable problems and it really helps take care of that fluttering I get in my left ear. Sorry I didn't get this out sooner. We've had problems with our modem. Lisa
