<<Disclaimer: Verify this information before applying it to your situation.>> I recently contacted Parke-Davis regarding a perscription medication I am taking. The representative that I spoke to (Matt) said that all their perscription drugs are gluten-free EXCEPT something called NARDIL (I don't know what it is used for). For more information, call their toll-free number at: 1-800-223-0432 or write to: PARKE-DAVID Warner-Lambert Company 201 Tabor Road Morris Plains, NJ 07950 USA Attn: Medical Affairs Department
