How Orlistat Differs from GLP-1 Weight Loss Treatments
Orlistat vs GLP-1: Understanding the Key Differences
Orlistat is not a GLP-1 receptor agonist—it's a lipase inhibitor that works through a completely different mechanism. While GLP-1 medications work on brain receptors to reduce appetite, orlistat acts locally in your digestive system to block approximately one third of dietary fat from being absorbed. This unabsorbed fat passes naturally through your body, potentially supporting weight management when combined with a reduced-calorie, lower-fat diet.
How Prescription Orlistat Works in Your Body
Unlike GLP-1 treatments that affect hormones and appetite signals, orlistat 120mg capsules work by inhibiting lipase enzymes in your gut. These enzymes normally break down dietary fat for absorption—when blocked, roughly one third of the fat you eat cannot be digested or absorbed into your bloodstream. This mechanism makes orlistat suitable for adults with a BMI of 30 or above, or 28 with weight-related health conditions, following clinical assessment by a UK-licensed prescriber.
Orlistat Prescription Options and Pricing
We stock both generic orlistat 120mg and branded Xenical 120mg—both contain identical active ingredients and deliver the same clinical effects. Generic orlistat offers excellent value: 2 weeks (42 capsules) costs £16.89, reduced to £15.20 with EDM10. For 12 weeks (252 capsules), pay £95.99 or £86.39 with discount code EDM10. Branded Xenical costs £21.50 for 2 weeks (£19.35 with EDM10) or £128.99 for 12 weeks (£116.09 with code). Both require the same online clinical assessment and prescription approval.
Clinical Assessment and Prescription Process
Unlike some weight loss products, orlistat 120mg is prescription-only and requires individual clinical assessment. Our UK-licensed prescribers review your medical history, current medications, and BMI to determine suitability. The online consultation replaces traditional GP appointments—complete your health questionnaire, receive prescriber review, and if appropriate, your prescription is dispensed by our GPhC-registered Leicester pharmacy for next day delivery across the UK.
Managing Orlistat Treatment Effectively
Success with orlistat depends on following a lower-fat diet alongside the medication. Take one 120mg capsule with each main meal containing fat—maximum three capsules daily. Keeping meals to approximately 15g fat each significantly reduces gastrointestinal side effects while maximising the treatment's potential benefits. Most patients experience fewer side effects after the initial weeks as their diet adapts. A daily multivitamin taken at bedtime is recommended, as orlistat may reduce absorption of fat-soluble vitamins.
