Orlistat vs Mounjaro: Key Differences
When comparing orlistat and Mounjaro for weight management, several important differences emerge. Orlistat works locally in your digestive system, blocking approximately one third of dietary fat absorption through lipase inhibition. It's available as convenient oral capsules taken three times daily with main meals. Mounjaro (tirzepatide), conversely, is a weekly injectable GLP-1 receptor agonist that affects blood sugar and appetite regulation. Both require prescription following clinical assessment, but orlistat offers established safety data spanning over two decades of clinical use.
Cost Comparison and Savings
Orlistat presents significant cost advantages over injectable alternatives. Generic orlistat 120mg starts from £16.89 for a 2-week supply, reduced to just £15.20 with code EDM10. Four-week supplies cost £32.99 (£29.69 with EDM10), whilst 12-week supplies offer excellent value at £95.99 (£86.39 with discount). Branded Xenical provides the same clinical effect at £21.50 per fortnight (£19.35 with EDM10). Code EDM10 applies to every order — new and returning customers save 10% without needing loyalty cards or minimum spend requirements.
Mechanism and Effectiveness
Orlistat's mechanism differs fundamentally from Mounjaro. Whilst Mounjaro acts systemically on hormone receptors, orlistat works exclusively in your gut without significant systemic absorption. This targeted approach means orlistat blocks dietary fat absorption whilst allowing normal carbohydrate and protein digestion. The unabsorbed fat passes naturally through your system, reducing caloric intake from high-fat meals. Clinical studies demonstrate orlistat's effectiveness when combined with reduced-calorie, lower-fat diets and increased physical activity.
Administration and Convenience
Orlistat capsules offer convenience advantages over weekly injections. Take one 120mg capsule with each main meal containing fat — typically three times daily. If you miss a meal or eat fat-free foods, simply skip that dose. No injection sites, refrigeration requirements, or injection technique training needed. Alli 60mg provides a lower-strength option for those preferring gentler introduction, available in 4-week supplies from £28.99 (£26.09 with EDM10).
Side Effect Profiles
Both treatments have distinct side effect profiles requiring consideration. Orlistat's side effects are primarily gastrointestinal, directly related to dietary fat content. Higher fat meals increase the likelihood of oily stools, urgent bowel movements, or anal leakage. These effects can be minimised by keeping meals low in fat (approximately 15g per meal). Mounjaro's side effects typically include nausea, vomiting, and gastrointestinal upset, particularly during dose escalation phases.
