Manufacturer Voluntarily Withdraws Lotronex

Published: September, 2005

Lotronex (alosetron) is a prescription medication used to treat diarrhea-predominant irritable bowel syndrome in women. Last month, the Food and Drug Administration issued important safety warnings for the use of this drug based upon reports of intestinal damage due to impaired blood flow to the intestine (ischemic colitis) and complications of severe constipation (bowel obstruction and rupture) in patients on Lotronex. (See the Family Health Guide Online update on Lotronex).

On November 30, the manufacturer (Galaxo Wellcome) informed the FDA that it will voluntarily remove this drug from the market. Any patient currently taking Lotronex should contact her physician to discuss other treatment options. For more information, please visit the Center for Drug Evaluation and Research Web page on Lotronex or call 888-INFO-FDA (888-463-6332).
