Lilly Warns Of Zyprexa, Zyrtec Confusion

Eli Lilly and Co. has changed the labeling on its antipsychotic Zyprexa to avoid confusion with Pfizer Inc.'s allergy medicine Zyrtec after some patients were given the wrong drug. Lilly said in a letter to psychiatrists and pharmacists that it has received 79 reports of such mix-ups since Zyprexa, which is used to treat schizophrenia and bipolar disorder, was introduced in 1996. The letter, dated Jan. 26, was posted Tuesday on the U.S. Food and Drug Administration's Medwatch Web site.
