Why Understanding Orlistat's Mechanism Matters for Your Purchase

How Orlistat Works in Your Body

Orlistat works by blocking lipase enzymes in your digestive system, preventing approximately one third of dietary fat from being absorbed. This fat passes naturally through your body rather than contributing to weight gain. Unlike appetite suppressants that affect your brain, orlistat acts locally in your gut, making it a targeted approach to weight management. This mechanism explains why following a lower-fat diet is essential — it maximises effectiveness whilst minimising gastrointestinal side effects.

Orlistat Safety and Overdose Considerations

Understanding orlistat's mechanism helps prevent misuse. Taking more than the recommended dose (one 120mg capsule with each main meal, maximum three daily) won't increase fat blocking beyond approximately one third. An orlistat overdose could increase side effects without additional benefit. Our UK-licensed prescribers assess your suitability and provide clear dosing guidance. Generic orlistat 120mg costs £32.99 for 4 weeks (£29.69 with EDM10), whilst branded Xenical costs £42.99 for the same period.
