Understanding How Orlistat Works - Order Today
How Does Orlistat Work in Your Body?
Orlistat works as a lipase inhibitor, acting locally in your digestive system to block approximately one third of the fat you eat from being absorbed. Unlike appetite suppressants that affect your brain, orlistat works directly in your gut by inhibiting enzymes called lipases that break down dietary fat. The unabsorbed fat passes naturally through your body, helping reduce calorie intake from fat when used alongside a reduced-calorie, lower-fat diet.
Private Prescription Route - Faster Than NHS
Our private prescription service offers faster access to orlistat without NHS waiting lists. Complete an online clinical assessment reviewed by UK-licensed prescribers, with prescription-only orlistat 120mg available from £29.69 for 4 weeks (generic) or Xenical from £38.69. Following clinical approval, your medication is dispensed by our GPhC-registered pharmacy and delivered discreetly to your address. Use EDM10 for 10% off every order.
Choose Your Orlistat Option
Generic orlistat 120mg offers the most cost-effective option at £32.99 for 4 weeks (£29.69 with EDM10). Branded Xenical 120mg contains the identical active ingredient at £42.99 for 4 weeks (£38.69 with EDM10). For those preferring lower strength, Alli 60mg is available at £28.99 for 4 weeks (£26.09 with EDM10). All options require clinical assessment, with 8-week and 12-week supplies offering better value.
Clinical Assessment Process
Our online consultation replaces traditional GP appointments, with qualified UK prescribers reviewing your medical history, current medications, and weight management goals. Orlistat may be suitable for adults with BMI 30+ or BMI 28+ with weight-related conditions like diabetes or high blood pressure. Following prescriber approval, your chosen treatment is dispatched within 24 hours with tracked delivery across the UK.
Maximising Orlistat Effectiveness
Orlistat works best when meals contain no more than 15g fat each, taken three times daily with main meals. This approach minimises gastrointestinal side effects whilst maximising fat-blocking benefits. Your prescriber will provide detailed guidance on optimising treatment alongside your reduced-calorie diet and exercise plan. Regular monitoring ensures continued suitability and effectiveness.
