Understanding How Orlistat Supports Weight Management

How Orlistat Works in Your Body

Orlistat is a lipase inhibitor that works locally in your digestive system to support weight management. Unlike appetite suppressants that act on the brain, orlistat works by inhibiting enzymes called lipases that break down dietary fat. When these enzymes are blocked, approximately one third of the fat you eat cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your digestive system and is eliminated.

Clinical Mechanism of Fat Absorption Blocking

The orlistat mechanism targets pancreatic and gastric lipases in your gut. By inhibiting these enzymes, orlistat prevents the breakdown of dietary triglycerides into absorbable fatty acids and monoglycerides. This process reduces calorie intake from dietary fat when used alongside a reduced-calorie, lower-fat diet and increased physical activity.

Prescription Orlistat Options Available

EverydayMeds offers prescription-strength orlistat in two forms. Generic orlistat 120mg provides excellent value at £32.99 for 4 weeks (£29.69 with EDM10), whilst branded Xenical 120mg costs £42.99 for 4 weeks (£38.69 with EDM10). Both contain identical active ingredients and work through the same fat-blocking mechanism. For those preferring lower-strength treatment, Alli 60mg is available at £28.99 for 4 weeks (£26.09 with EDM10).

Who May Benefit from Prescription Orlistat

Orlistat may be suitable for adults with a BMI of 30 or above, or 28 and above with weight-related health conditions like type 2 diabetes or high blood pressure. Following an online clinical assessment, UK-licensed prescribers determine treatment suitability. The prescription weight loss tablets work best when fat intake is kept low - approximately 15g per meal - which also minimises gastrointestinal side effects.

Expected Treatment Timeline and Monitoring

Orlistat treatment typically starts with a 4-week supply to assess tolerance and response. Many patients continue with 8-week or 12-week supplies for ongoing weight management support. Our 12-week orlistat supply costs £95.99 (£86.39 with EDM10), whilst Xenical 12-week treatment costs £128.99 (£116.09 with EDM10). Regular monitoring with healthcare professionals ensures optimal results.
