Xenical will help you lose weight only when you use it in conjunction with physician supervised reduced calorie diet and exercise.

According to medical experts, Xenical should only be administered by patients who are suffering with obesity. In relation, it is only advised as a last resort for those who have who have repeatedly tried, but failed to achieve significant weight loss through normal means. Xenical is a prescription drug, and like all other medicines, it is subject to a number of side effects.

Before we discuss further, please rest assured that Xenical is a safe and effective drug which has undergone several clinical trials and has been approved by the FDA as a prescription only weight loss drug. Most of the Xenical side effects are mild to moderate and are not likely to affect everybody.

The majority of Xenical side effects is thought to be minor in nature, and will ordinarily reside with treatment on their own. Minor side effects are usually related to the digestive system as this is where Xenical works.

Some of the commonly reported minor side effects of Xenical are -

• Increased frequency of bowel movements
• Fecal incontinence where you have uncontrolled, spontaneous bowel movements
