How Orlistat 120mg Works in Your Body
Orlistat 120mg works by inhibiting lipase enzymes in your digestive system. These enzymes normally break down dietary fat so it can be absorbed into your bloodstream. When orlistat blocks these enzymes, approximately one third of the fat you eat passes through your body undigested and is naturally excreted. This mechanism reduces your calorie intake from fat, supporting weight loss when combined with a reduced-calorie, lower-fat diet.
Unlike appetite suppressants that act on the brain, orlistat works locally in your gut and is not significantly absorbed into your bloodstream. This targeted approach means the medication focuses specifically on fat absorption rather than affecting your central nervous system.
Standard Orlistat 120mg Dosage Guidelines
The recommended dosage is one 120mg capsule taken three times daily with each main meal containing fat. Take each capsule immediately before, during, or up to one hour after eating. If you skip a meal or eat a meal with no fat content, you can skip that dose. Never exceed three capsules per day.
At EverydayMeds, our pack sizes align with this dosing schedule. A 4-week supply contains 84 capsules (£32.99, or £29.69 with EDM10), while our 12-week supply contains 252 capsules (£95.99, or £86.39 with EDM10). Both generic orlistat and branded Xenical follow identical dosing guidelines.
Why the Mechanism Matters for Your Weight Loss Journey
Understanding how orlistat works helps you maximise its effectiveness. Since it blocks approximately one third of dietary fat absorption, keeping your fat intake low per meal minimises side effects while maintaining the medication's weight management benefits. Most prescribers recommend limiting fat to around 15g per meal, spread evenly across three main meals.
The unabsorbed fat that passes through your system serves as a direct indicator that the medication is working. While gastrointestinal side effects may occur initially, they typically reduce as you adapt to a lower-fat diet pattern.
Generic Orlistat vs Branded Xenical: Same Mechanism, Different Prices
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients and work through the same fat-blocking mechanism. The clinical effect is equivalent, but generic orlistat offers significant cost savings. A 4-week Xenical supply costs £42.99 (£38.69 with EDM10) compared to £32.99 (£29.69 with EDM10) for generic orlistat—saving you approximately £9 per month.
Some patients prefer the branded option, while others choose generic orlistat for better value. Your prescriber can discuss which option suits your preferences during your online clinical assessment.
