Compare Prescription Fat Blocking Options & Prices
How Xenical and Orlistat Block Dietary Fat
Xenical and generic orlistat both contain orlistat 120mg, which works by blocking approximately one third of the fat you eat from being absorbed. The medication inhibits lipase enzymes in your digestive system, preventing around 30% of dietary fat from entering your bloodstream. This unabsorbed fat passes naturally through your body, potentially supporting weight management when used alongside a reduced-calorie, lower-fat diet and increased physical activity.
UK Prescription Weight Loss Treatment Prices
Generic orlistat 120mg offers the most cost-effective option, starting at £16.89 for 2 weeks (£15.20 with EDM10). Our 4-week supply costs £32.99 (£29.69 with code EDM10), whilst 12-week treatment is £95.99 (£86.39 with discount). Branded Xenical contains identical orlistat 120mg but costs £21.50 for 2 weeks (£19.35 with EDM10), rising to £128.99 for 12 weeks (£116.09 discounted). Both products block the same amount of fat and require the same clinical assessment process.
Clinical Assessment for UK Prescriptions
Our UK-licensed prescribers review each application individually to determine suitability for orlistat treatment. The assessment considers your BMI, medical history, current medications, and weight management goals. Orlistat may be prescribed for adults with a BMI of 30 or above, or BMI 28+ with weight-related health conditions like type 2 diabetes or high blood pressure. Complete your online consultation to discover if prescription fat blocking treatment could support your weight management journey.
Managing Treatment Effectively
Orlistat works best when each meal contains no more than approximately 15g of fat, helping minimise gastrointestinal side effects whilst maximising the medication's effectiveness. Take one 120mg capsule with each main meal containing fat, up to three times daily. If you skip a meal or eat fat-free food, you can omit that dose. Most patients find side effects reduce significantly when following a structured lower-fat eating plan alongside their prescription treatment.
