An item in “Tips from Other Journals,” entitled “Overview of Methods for Treating Allergic Rhinitis” (January 1, 2000, page 207), contained dosage errors in the accompanying table on second-generation antihistamines. The dosage approved by the U.S. Food and Drug Administration for cetirizine is 5 to 10 mg once daily; the approved dosage for loratadine is 10 mg once daily and the approved dosage for loratadine with pseudoephedrine is 10 mg/240 mg once daily. The half-life of claritin was misstated; it is 28 hours. The corrected table is reprinted below.
