<<Disclaimer: Verify this information before applying it to your situation.>> I called McNeil Consumer Products last week regarding the gf status of Tylenol. The representative said that the regular and extra strenthly caplets have been tested and they are gf. However, the gelcaps have not been tested and they cann't guarantee status. Three years ago they told me the gelcaps were not gf. Also, I recently bought a Benedryl substitute Wal-dryl 25 at Walgreens. I talked with a representative and she said they were gf. These are for allergies and so the type you would take if you break out in hives, etc. They are about one-half the price of Benedryl and they were also on sale.
