What are the side effects of Xenical?

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 medicine 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.
