What are the side effects of Xenical?


Xenical® (orlistat) is a prescription weight-loss medication that prevents fat in food from being absorbed into the body. Some gastrointestinal side effects have been linked to Xenical® usage, but it is generally tolerated well. Doctors prescribe the drug for people who meet certain criteria for obesity or who are at risk for health-related problems because of their weight.

Potential side effects

The most commonly reported side effects of Xenical® include stomach pain and discomfort, gas, an urgent need to move the bowels, fatty or oily stools, oily rectal discharge, diarrhea, and a loss of bowel control. You're more likely to have these side effects with higher doses of Xenical® and with a high-fat diet. These side effects go away in most people after 4 weeks of therapy, but it can continue for longer than 6 months in some individuals. If these side effects continue or get worse, you should talk to your health care provider. Do not use Xenical® if you have problems absorbing food, gallbladder disease, or eating disorders such as anorexia or bulimia.
