Stop taking Xenical and seek emergency medical attention if you experience a rare allergic reaction including shortness of breath; closing of your throat; swelling of your lips, tongue, or face; or hives. Other, less serious side effects are more likely to occur. Continue to take Xenical and talk to your doctor if you experience oily spotting, gas with discharge, an urgent need to go to the bathroom, oily or fatty stools, an oily discharge, an increased number of bowel movements, an inability to control bowel movements, or orange or brown colored oil in your stool. The bowel changes listed above are a natural effect of blocking fat and indicate that Xenical is working. They generally occur early in treatment, particularly after meals containing higher amounts of fat than are recommended. These symptoms are usually temporary and lessen or disappear as you continue treatment and keep to your recommended diet of meals containing 30% fat. Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.
