Usual Adult Dose for Irritable Bowel Syndrome

Tegaserod was voluntary withdrawn from the US market by the manufacturer in March, 2007 due to increased reports of serious cardiovascular adverse events, including angina, heart attacks, and stroke. However, the FDA announced on July 27, 2007 that it is allowing the restricted use of tegaserod under a treatment investigational new drug (IND) protocol to treat IBS-C and CIC in women younger than 55 who meet specific guidelines. These patients must meet strict criteria and have no known or preexisting heart complications and be in critical need of this therapy. Tegaserod will stay off the market for general use. Prescribers with IBS-C or CIC patients who meet the IND criteria should contact Novartis at 888-669-6682 or 800-QUI-NTILE. Those patients who do not qualify for the tegaserod treatment protocol may contact FDA's Division for Drug Information regarding other options at 888-463-6332.

Women:
Initial dose: 6 mg orally twice a day before meals for 4 to 6 weeks.
Maintenance dose: If patients respond to therapy after 4 to 6 weeks, an additional 4 to 6 week course may be prescribed. Efficacy beyond 12 weeks has not been established.

Men: Safety and efficacy have not been established.

Other Comments

Tegaserod should be taken before meals.

If the patient is unable to swallow whole tablets, tegaserod tablets may be crushed and mixed with water or apple juice to make a suspension. Apple juice may be preferable because it masks the taste of tegaserod, forms a homogenous suspension, and the drug's dissolution profile is like that of whole tablets. Tegaserod is stable in apple juice for 1 hour at room temperature and for 3 days at 5 degrees C. Milk, applesauce, yogurt, orange juice, and chocolate-hazelnut spread are not recommended because they do not form homogenous suspensions and/or dissolution is not comparable to the tablets which could adversely affect bioavailability.
