Compare Orlistat Doses: Which Should You Choose?

Orlistat 120mg vs Xenical 120mg: Identical Clinical Effect

Both orlistat 120mg and Xenical 120mg contain exactly the same active ingredient at the same dose. They work identically by blocking approximately one third of dietary fat absorption in your gut. The clinical effect is equivalent—Xenical is simply the branded version manufactured by Roche, while generic orlistat offers the same treatment at a lower cost.

Price Comparison: Significant Savings with Generic

Generic orlistat 120mg costs £32.99 for 4 weeks (£29.69 with EDM10), while Xenical 120mg costs £42.99 for 4 weeks (£38.69 with EDM10). That's a saving of approximately £9 per month choosing generic. For 12-week supplies, orlistat costs £95.99 (£86.39 with EDM10) compared to Xenical's £128.99 (£116.09 with EDM10)—saving nearly £30 over three months.

Alli 60mg: Lower-Strength Alternative

Alli 60mg contains half the dose of prescription-strength orlistat. At £28.99 for 4 weeks (£26.09 with EDM10), it offers a lower-strength starting point. While less potent than 120mg versions, Alli may suit those preferring a gentler approach to weight management alongside a reduced-calorie, lower-fat diet.

Which Orlistat Dose Is Right for You?

Your choice depends on clinical suitability and personal preference. All three options require assessment by a qualified UK prescriber. Orlistat 120mg and Xenical 120mg are prescription-only medicines suitable for adults with BMI 30+ or BMI 28+ with weight-related health conditions. Our online clinical assessment takes minutes—complete your consultation today.
