Xenical is one of the newer types of prescription weight control drugs on the market, having been approved for use by the America Food and Drug Administration in 1999. It is designed specifically for considerably overweight people to lose weight. Unlike other types of diet pills which suppress your appetite, it actually blocks absorption of some of the fat from food consumed by the patient. While most other diet pills work in the brain, this one works in the body, but stopping the lipase enzyme (which is found in the intestinal tract and breaks down fat for the body to absorb it) from working. This drug blocks absorption of up to 30% of fat, which is then removed from the body through bowel movements.
Dosage: Sold in 120mg capsules, this medication is only recommended for people with a BMI (Body Mass Index) of 30 or greater, or by those with a BMI of 27 or greater and also suffering from diabetes, high cholesterol or high blood pressure. Manufacturers recommend that one capsule should be taken three times a day with meals, or alternatively up to an hour after eating food that contains fat. For maximum benefit from this drug, each meal consumed should contain less than 30% of its calories as fat. If a meal is fat-free or you do not consume a particular, then you can skip the dose intended for that meal.
Xenical Side Effects: As this medication works by blocking fat from being absorbed into your body, most users experience a change in bowel movements and patterns, including gas with an oily discharge, an urgency to make bowel movements, an increased number of bowel movements, and oily bowel movements. These side effects are a result from the body blocking the absorption of fat, and are intensified if you consume a meal with a high fat or calorie count. While they subside in most users after a couple of weeks of taking this drug, some users may find that they will continue – sometimes up to six months into using these pills.
Precaution: This medication shouldn’t be taken by pregnant or nursing women. It also shouldn’t be taken by people who suffer from eating disorders. As this drug inhibits the absorption of certain vitamins (including vitamins A, D, E and K, as well as beta-carotene), a multi-vitamin should be taken daily. People taking cyclosporine should consult with their physician before taking these diet pills.
