KENILWORTH, N.J., March 28, 2007 -- Schering-Plough Corporation (NYSE: SGP) today announced that prescription-strength MiraLAX® (polyethylene glycol 3350) is now available as an over-the-counter (OTC) treatment for occasional constipation. The innovative formula of MiraLAX works with the body to increase the frequency of bowel movements without causing the side effects of cramps and gas. MiraLAX allows a comfortable, easy and complete bowel movement. MiraLAX has a strong safety profile and is not known to be habit forming. "Laxatives that work gently with the body are preferred because people can live their lives normally. Some other laxatives may cause uncomfortable cramps. MiraLAX is a welcome alternative. It offers effective constipation relief, allowing the patient to regain control," said Jack A. DiPalma, M.D., immediate past president of the American College of Gastroenterology and director of the division of gastroenterology at University of South Alabama College of Medicine.

MiraLAX is the first Rx-to-OTC switch in the laxative category in 30 years. Nearly 70 percent of constipated consumers who tried MiraLAX preferred it versus their usual laxative.1 MiraLAX brings the body back to its natural rhythm by using the body’s own water to gently increase the frequency of bowel movements and to soften the stool so it is easier to pass. MiraLAX is taken once daily and comes in a powder form which dissolves completely in any common beverage (coffee, tea, juice, soda).

Constipation is a common gastrointestinal complaint, affecting more than 65 million Americans.2 Constipation can stem from lifestyle causes such as diet and inadequate fluid intake; physical inactivity; stress or anxiety; and medical conditions such as pregnancy, diabetes or hypothyroidism.3 Constipation can also be caused or exacerbated by narcotic analgesics, antacids, anti-cholinergics or iron supplements. On average, more than twice as many women as men suffer from constipation.2

"MiraLAX is the latest in a line of successful prescription-to-OTC switches by Schering-Plough," said Stan Barshay, chairman of Schering-Plough HealthCare Products. "We are pleased to bring the benefits of MiraLAX, a proven medication, to the millions of Americans suffering from constipation."
