Which Should You Choose: Orlistat or Xenical?
Identical Clinical Effect, Different Price Points
Both Orlistat 120mg and Xenical 120mg contain the same active ingredient at identical doses, providing equivalent weight management support when used alongside a reduced-calorie, lower-fat diet. Generic orlistat offers significant cost savings - a 4-week supply costs £29.69 with EDM10, compared to £38.69 for branded Xenical. Over 12 weeks, choosing generic orlistat saves £29.70 whilst delivering the same clinical benefit of blocking approximately one third of dietary fat absorption.
Understanding Why Orlistat Causes Digestive Side Effects
Both orlistat and Xenical work by inhibiting lipase enzymes in the gut, preventing absorption of approximately one third of dietary fat. This unabsorbed fat passes naturally through the digestive system, which may cause gastrointestinal side effects including oily stools, increased bowel movements, and abdominal discomfort. These effects occur with both generic orlistat and branded Xenical because they contain identical active ingredients. Keeping meals low in fat (approximately 15g per meal) significantly reduces the likelihood and severity of these side effects regardless of which version you choose.
