Prescription Weight Loss Medications - Xenical / OrlistatPlease read Part One of this series of articles on Weight Loss Medications before continuing. It contains important advice applicable to all forms of weight loss medications. Orlistat is the generic name of the prescription weight loss drug more commonly known by the brand name of Xenical. Important Update: Research suggests that Xenical use in conjunction with an oxylate-rich diet increases the risk of kidney stone formation - Kidney International - Volume 66 Issue 2 Page 676 - August 2004 Type of Weight Loss Medication (Drug):Lipase Inhibitor. Orlistat / Xenical works in the intestines to block absorption of dietary fat into the bloodstream, thereby reducing the number of calories you get from a meal. This undigested fat is then discharged via your bowel movements. At the usual dosage level, it cuts fat absorption by almost one-third. Combined with a low-calorie diet, it is used to promote weight loss and discourage the return of unwanted pounds. The Orlistat / Xenical is prescribed for the frankly obese and for merely overweight people who have other health problems such as high blood pressure, diabetes, or high cholesterol levels. It works in a completely different way than the Phentermine prescription weight loss drugs such as Adipex and Ionamin, the Phendimetrazine weight loss medications such as Bontril, and the Benzphetamine drugs such as Didrex, and in a different way again than Meridia. Brief description of use:Take a capsule of Orlistat / Xenical during, or up to 1 hour after, each meal. You should follow a nutritionally balanced, low-calorie diet that provides no more than 30 percent of its calories from fat. If you miss a meal, or the meal contains no fat, you can skip the accompanying dose of Orlistat / Xenical. Orlistat / Xenical is also useful in patients with a certain weight who may also have high blood pressure, diabetes, high cholesterol, or heart disease and therefore for whom most other prescription weight loss medications are inappropriate. Orlistat / Xenical produces rather embarrassing and often uncontrollable bowel motions if your food intake is rich in fats which, due to this weight loss drug, are not absorbed. In this way, Orlistat / Xenical "trains" a person into eating low fat foods and meals. Developing this behavioral change in your diet for a year or two will hopefully instill permanent dietary change even after the treatment is no longer required. Weight loss begins within 2 weeks and continues for 6 to 12 months. The effect of using Orlistat / Xenical for more than 2 years is still unknown and therefore not recommended. Use only under the recommendation and supervision of a medical practioner, and use only as directed. Contraindictions, warnings & risks:Follow your doctor's directions at all times and keep all medical appointments while using this weight loss medication. Orlistat / Xenical blocks your body's absorption of some fat-soluble vitamins and beta carotene. Therefore, when you use Orlistat / Xenical you should take a daily multivitamin supplement that contains vitamins A, D, E, K, and beta-carotene. Take the vitamin once a day, 2 hours before or 2 hours after taking this weight loss medication. Not suitable for children except where recommended by a doctor. Safety and efficacy of this drug in children has not been established. Tell your doctor if you have ever had any unusual or allergic reaction to Orlistat / Xenical or any other drug (whether prescription, over-the-counter or illicit).

Tell your doctor if you have or have ever had anorexia nervosa, glaucoma, high blood pressure, arrhythmias, a stroke, gallstones, coronary artery disease, congestive heart failure, thyroid disease, seizures, or liver, kidney, or heart disease, or if you consistently have problems absorbing food (malabsorption syndrome).

Side effects are common in the early stages of use, though generally disappear as you adjust your diet to low fat content. If the side effects are severe or continue for a prolonged period, discuss them with your doctor. The most common side effects include oily, spotting bowel movements, gas with discharge, urgent need to have a bowel movement, oily or fatty stools, an oily discharge, increased number of bowel movements, inability to control bowel movements, orange or brown color of a bowel movement, stomach pain, irregular menstrual periods.

If you miss a dose, take the missed dose as soon as you remember unless it is more than 1 hour since you ate a main meal.
