Understanding Orlistat Dosage for Effective Weight Loss
How Long Should You Take Orlistat for Weight Loss?
The duration of orlistat treatment varies depending on individual response and weight management goals. Most prescribers recommend an initial 12-week treatment period to assess effectiveness. During this time, orlistat 120mg is taken three times daily with each main meal containing fat, working to block approximately one third of dietary fat absorption. Our 12-week supply of generic orlistat (252 capsules) costs £95.99, or just £86.39 with code EDM10 - representing excellent value for comprehensive weight loss support.
Orlistat 120mg vs Xenical: Same Dosage, Different Prices
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients at the same therapeutic dose. The standard dosage remains one 120mg capsule taken three times daily with fat-containing meals. However, costs differ significantly: a 4-week supply of generic orlistat costs £32.99 (£29.69 with EDM10), whilst branded Xenical costs £42.99 (£38.69 with EDM10). Both work identically alongside a reduced-calorie, lower-fat diet to support weight management goals.
Starting Your Orlistat Treatment Journey
Begin with our 2-week starter supply to assess tolerance before committing to longer durations. Generic orlistat 42 capsules cost £16.89 (£15.20 with EDM10), whilst Xenical 42 capsules cost £21.50 (£19.35 with EDM10). Most patients find gastrointestinal side effects reduce after the first few weeks as dietary habits adapt. Our online clinical assessment determines your suitability for prescription weight loss treatment, with UK-licensed prescribers reviewing your individual circumstances.
Maximising Results: Dosage Timing and Diet
Take one orlistat 120mg capsule immediately before, during, or up to one hour after each main meal containing fat. If you miss a meal or eat a fat-free meal, skip that dose. This flexible dosing approach helps minimise side effects whilst maintaining effectiveness. Combine treatment with no more than 30% daily calories from fat, spread evenly across three meals. A daily multivitamin taken at bedtime supports optimal nutrition during weight loss.
Long-term Treatment and Monitoring
Extended orlistat treatment beyond 12 weeks may be appropriate for sustained weight management, subject to prescriber review. Our 8-week supplies offer convenience for established users: generic orlistat 168 capsules for £63.99 (£57.59 with EDM10) or Xenical 168 capsules for £86.99 (£78.29 with EDM10). Regular monitoring ensures treatment remains suitable and effective as part of your ongoing weight management programme.
