Orlistat vs Xenical: The Key Facts

Orlistat 120mg and Xenical 120mg are clinically equivalent medications containing the same active ingredient at identical doses. Both work by blocking approximately one third of dietary fat absorption and require prescription following clinical assessment. The primary difference lies in cost—generic orlistat offers significant savings over branded Xenical without compromising effectiveness.

Price Comparison: Your Options

Generic orlistat 120mg starts from £15.20 for 2 weeks (42 capsules) with code EDM10, whilst branded Xenical costs £19.35 for the same supply. For a 4-week treatment, orlistat costs £29.69 compared to Xenical at £38.69—saving you £9 monthly. Both medications require the same dosing schedule: one capsule three times daily with each main meal containing fat.

Alli 60mg: The Lower-Strength Alternative

Alli contains half the dose of prescription-strength orlistat, making it suitable for those preferring a gentler starting point. At £26.09 for 4 weeks with EDM10, Alli blocks a smaller proportion of dietary fat but may cause milder gastrointestinal effects. All three options work best alongside a reduced-calorie, lower-fat diet.

Which Should You Choose?

If cost is your priority, generic orlistat 120mg delivers identical results to Xenical at a lower price. Some patients prefer branded Xenical for peace of mind, whilst others choose Alli 60mg as a lower-strength option. Your prescriber can help determine which strength and formulation suits your individual circumstances following clinical assessment.
