Which Strength Should You Choose?

Orlistat 120mg and Xenical 120mg are prescription-only medicines that block approximately one third of dietary fat absorption. Alli 60mg provides half the dose for those preferring a gentler starting approach. All three work by inhibiting lipase enzymes in your digestive system, preventing fat absorption rather than acting on your brain. The choice depends on your budget preferences and whether you prefer branded or generic medication.

How They Work Identically

Whether you choose orlistat, Xenical, or Alli, the mechanism remains the same — blocking lipase enzymes to prevent dietary fat absorption. Prescription-strength options (120mg) may help reduce approximately one third of fat from each meal, whilst Alli 60mg blocks a smaller proportion. All must be used alongside a reduced-calorie, lower-fat diet and increased physical activity for optimal results.

Which Offers Best Value?

Generic orlistat 120mg provides the most cost-effective option without compromising clinical effectiveness. Over 12 weeks, you save £29.70 choosing orlistat over Xenical. However, some patients prefer branded Xenical for peace of mind. Alli 60mg sits between both in terms of pricing but delivers lower potency, potentially requiring longer treatment duration.

Order Process & Delivery

All three options require clinical assessment by our UK-licensed prescribers through a confidential online consultation. Following prescriber approval, your chosen treatment is dispensed by our GPhC-registered pharmacy and delivered discreetly with next day delivery across the UK. Use code EDM10 for 10% off every order, whether choosing orlistat, Xenical, or Alli.
