Xenical.

Xenical (orlistat) is used for the treatment of obese people that are unable to lose their weight by simply dieting and exercising. This medicine can also be used after you have already lost some weight to maintain the result achieved. You are supposed to take Xenical three times a day before meals containing fat. Make sure your meal does not contain more fat than 30% f the total serving, as otherwise Xenical may not be as efficient. If there is no fat in your food, skip your dose of Xenical. If you are taking anticoagulants, medications for thyroid, other weight loss medications, medications to control blood pressure, or medications for diabetes, let your doctor know in advance as you may need to be taking a lower dose. Mild side effects of Xenical include the following symptoms: loose stools, headache, irregular menstrual periods, oily or fatty stools, stomach pain, anxiety, gas with oily spotting, increased number of bowel movements, urgent need to have a bowel movement, and oily spotting. More serious side effects that need to be reported include rash, difficulty breathing or swallowing, continuous abdominal pain, itching, and hives.
