To the Editor.—  Patients who have urticaria are frequently treated with hydroxyzine. A number of articles have implicated sensitivity to tartrazine (FD&C Yellow No. 5) as a causative factor in cases of chronic urticaria.1,2 It is important for the dermatologists to be aware of which hydroxyzine products are free of this dye.I have been informed in a letter from the manufacturer of these products that hydroxyzine hydrochloride (Atarax), 25 mg and 50 mg, and all hydroxyzine (Vistaril) pamoate capsules and suspension contain tartrazine. However, hydroxyzine hydrochloride, 10 mg, 100 mg, and syrup forms, does not contain tartrazine dye.
