Orlistat vs Xenical: Which Should You Buy?

When Does Orlistat Start Working?

Both generic orlistat 120mg and branded Xenical 120mg start working immediately with your first dose. The medication blocks approximately one third of dietary fat from being absorbed, with effects occurring during the same meal when taken correctly. Take one capsule with each main meal containing fat - up to three times daily. The unabsorbed fat passes naturally through your digestive system within 24-72 hours of each dose.

Orlistat vs Xenical: Identical Clinical Effect

Generic orlistat 120mg and Xenical 120mg contain exactly the same active ingredient at identical doses. Both work by inhibiting lipase enzymes in your gut to reduce fat absorption by approximately one third. Whether you choose generic orlistat or branded Xenical, the mechanism of action, dosing schedule, and clinical outcomes are identical. The only meaningful difference is cost.

Price Comparison: Generic Saves You Money

Generic orlistat offers significant savings versus branded Xenical. For a 4-week supply (84 capsules): Generic orlistat costs £32.99 (£29.69 with EDM10) while Xenical costs £42.99 (£38.69 with EDM10). Over 12 weeks, choose generic orlistat at £86.39 versus Xenical at £116.09 - saving £29.70 with identical clinical effect. Both options include prescription following clinical assessment by our UK-licensed prescribers.

Alli 60mg: Lower-Strength Alternative

Alli 60mg provides half the dose of prescription-strength orlistat, blocking a smaller proportion of dietary fat. While less potent than 120mg options, Alli may suit those preferring a gentler starting point. Available at £26.09 for 4 weeks with EDM10 discount. However, prescription-strength orlistat 120mg or Xenical 120mg typically provide more comprehensive weight management support when used alongside a reduced-calorie, lower-fat diet.

How to Choose: Orlistat or Xenical?

Choose generic orlistat 120mg if you prioritise value - identical clinical effect at lower cost. Choose branded Xenical 120mg if you prefer the original Roche formulation. Both require the same online clinical assessment, work identically when orlistat starts working with your meals, and are dispensed by our GPhC-registered pharmacy in Leicester.
