The authors of the letter "Clozapine-Induced Priapism" (Joseph Ziegler, M.D., and David Behar, M.D., February 1992, pp. 272-273) thank Dr. Richard Balon for correcting the references. Reference 2 should read "Balon R, Berchou R, Han H: Priapism associated with thiothixene, chlorpromazine, and thioridazine (letter). J Clin Psychiatry 1987; 48:216." In reference 3 also, the journal is J Clin Psychiatry.
