Compare Prices: Orlistat vs Xenical vs Alli
Orlistat vs Xenical: The Key Differences
When choosing weight loss medication, understanding the difference between orlistat and Xenical helps you make the right decision. Both contain exactly the same active ingredient—orlistat 120mg—and work identically by blocking approximately one third of dietary fat absorption. The primary difference is cost, with generic orlistat offering substantial savings compared to branded Xenical.
Pricing Comparison: Which Offers Better Value?
Generic orlistat 120mg starts from just £15.20 for a 2-week supply (42 capsules) with code EDM10, compared to Xenical at £19.35 for the same supply. Over a 12-week treatment course, you could save over £29 by choosing generic orlistat (£86.39) instead of Xenical (£116.09). Both require the same prescription following clinical assessment by our UK-licensed prescribers.
Alli 60mg: The Lower-Strength Alternative
For those preferring a gentler approach, Alli 60mg offers half the strength of prescription orlistat. Priced from £26.09 for a 4-week supply with EDM10, Alli may cause fewer gastrointestinal side effects while still supporting weight management alongside a reduced-calorie, lower-fat diet.
How Do These Weight Loss Tablets Work?
All three products contain orlistat, which works by inhibiting lipase enzymes in your digestive system. This prevents approximately one third of dietary fat from being absorbed, with the unabsorbed fat passing naturally through your body. The medication works best when combined with meals containing no more than 15g of fat to minimise side effects.
Which Should You Choose?
Choose generic orlistat 120mg if you want maximum clinical effect at the lowest price. Opt for Xenical 120mg if you prefer the branded version from Roche. Consider Alli 60mg if you want to start with a lower dose. All options require commitment to a lower-fat diet and regular physical activity for optimal results.
