Orlistat vs Xenical: Which Should You Choose?
Identical Active Ingredient, Different Price
Orlistat 120mg and Xenical 120mg contain exactly the same active ingredient at the same dose. Both work identically by blocking approximately one third of dietary fat absorption in your digestive system. Generic Orlistat costs £29.69 for 4 weeks (with EDM10) compared to £38.69 for branded Xenical - a saving of £9 monthly. Both require prescription following online clinical assessment by our UK-licensed prescribers.
How Soon Both Medications Start Working
Whether you choose generic Orlistat or branded Xenical, both start working immediately after your first dose. You may notice gastrointestinal effects within 24-48 hours when eating fat-containing meals - this indicates the medication is blocking dietary fat absorption. Maximum effect typically occurs within the first week of treatment when combined with a reduced-calorie, lower-fat diet.
Clinical Equivalence
Both products deliver identical clinical outcomes. Generic Orlistat and branded Xenical are bioequivalent, meaning they work in exactly the same way in your body. The choice often comes down to personal preference and budget. Some patients prefer the branded option, while others choose generic Orlistat for the significant cost savings without compromising effectiveness.

Same Side Effect Profile
Both Orlistat and Xenical may cause identical gastrointestinal side effects including oily stools, increased bowel frequency, and urgent bowel movements. These effects can be minimised by keeping dietary fat intake low (approximately 15g per meal). Side effects indicate the medication is working by preventing fat absorption.
