Designed for patients who have tried and failed to lose weight on various diets, the following prescription drugs are used for patients who are medically classified as overweight or obese and where losing weight will yield a positive benefit to their health. The old amphetamine class of weight loss drugs had serious side effects and were highly addictive, this prevented patients being prescribed more than a one-month course – not long enough to lose significant amounts of weight. Fortunately with recent medical developments weight loss drugs now are extremely safe, effective and completely non-addictive enabling patients to use them continuously until their target weight loss has been attained. Xenical works very effectively by literally preventing most of the fat you eat being absorbed by the stomachs enzymes and therefore the fat and the high amount of calories it contains, passes right through your body and is excreted in your bowel movements. Reductamin on the other hand is a non-addictive appetite suppressant and you actually feel satisfied and full after eating less food. Manufactured by Roche, the prescription drug Xenical represents the same breakthrough for weight loss as Viagra did for potency. Xenical acts in a totally new way and actually prevents fat, which is high in calories being absorbed by your body – the fat and the calories literally go right through your body and are excreted. Because you do not have to starve yourself on an unrealistic diet plan this drug is used for patients who have tried and failed to lose weight on normal weight loss programmes. Providing you are not pregnant or breast feeding and do not have a serious liver disease and are overweight, then Xenical containing 120mg of the active drug Orlistat is safe to self administer. Take one capsule with water just before you eat any meal with a fat content. Side effects are minor and usually only occur in the early stages of treatment – they include flatulence and oily stools.
