O’Reardon, M.D., et al. titled “Desipramine Toxicity With Terbinafine” (Am J Psychiatry 2002; 159:492), the first sentence in the next-to-last paragraph should read, “After a single 250-mg dose of terbinafine, the elimination half-life is 16–100 hours; after 4 weeks of terbinafine, 250 mg/day, the mean plasma half-life is 22 days (3).”
