How Orlistat Supports Weight Management in the UK
How Does Orlistat Help with Weight Loss?
Orlistat works by blocking approximately one third of the fat you eat from being absorbed into your body. As a lipase inhibitor, it acts locally in your digestive system to prevent fat-digesting enzymes from breaking down dietary fat. The unabsorbed fat passes naturally through your body, potentially reducing your calorie intake from fat when used alongside a reduced-calorie, lower-fat diet.
Prescription Orlistat Options Available
We offer three prescription weight loss options following clinical assessment. Generic orlistat 120mg provides the most cost-effective treatment from £16.89 for 2 weeks (£15.20 with EDM10). Xenical 120mg offers the same clinical effect as the branded option from £21.50 for 2 weeks (£19.35 with EDM10). Alli 60mg is available as a lower-strength option from £28.99 for 4 weeks (£26.09 with EDM10). All contain orlistat as the active ingredient but at different strengths.
UK Online Prescription Process
Our regulated online consultation replaces the need for a face-to-face GP appointment. Complete your medical questionnaire including weight, health conditions, and current medications. A UK-licensed prescriber reviews your information and prescribes orlistat where clinically appropriate. Treatment is suitable for adults with a BMI of 30 or above, or 28 or above with weight-related health conditions like type 2 diabetes or high blood pressure.
What to Expect During Treatment
Orlistat may cause gastrointestinal side effects, particularly when eating high-fat meals. Keeping fat intake to approximately 15g per meal can significantly reduce side effects like oily stools or urgent bowel movements. Most patients find side effects improve as they adapt to a lower-fat diet. A daily multivitamin taken at bedtime is recommended as orlistat may reduce absorption of fat-soluble vitamins.
