<<Disclaimer: Verify this information before applying it to your situation.>> I heard an ad on the radio the other day for Rite Aid pharmacy. They gave an 800 number (it might have been 800-rite-aid) and said you could call this number 24 hours a day and speak to a pharmacist even if you were not a Rite-Aid customer. Don't know if they could answer the gluten-free questions either. Jean Jasinski
