How Orlistat Works - Clinical Evidence & UK Availability
How Does Orlistat Really Work?
Orlistat works by inhibiting lipase enzymes in your digestive system, preventing approximately one third of dietary fat from being absorbed into your body. This unabsorbed fat passes naturally through your system, which can support weight management when combined with a reduced-calorie, lower-fat diet and increased physical activity. Unlike appetite suppressants, orlistat acts locally in the gut rather than affecting your brain chemistry.
Orlistat UK Prescription Options & Pricing
Three orlistat options are available through our online prescription service. Generic orlistat 120mg offers excellent value from £29.69 for 4 weeks (with EDM10), whilst branded Xenical 120mg costs £38.69 for the same supply. Both contain identical active ingredients at the same clinical dose. Alli 60mg provides a lower-strength option at £26.09 for 4 weeks. All prices include the prescription consultation and next day delivery.
Clinical Evidence - Does Orlistat Really Work?
Orlistat is MHRA-approved for weight management in adults with a BMI of 30kg/m² or above, or 28kg/m² with weight-related health conditions like type 2 diabetes or high blood pressure. Clinical studies demonstrate that orlistat can support weight loss when used alongside dietary and lifestyle changes, though individual results vary. The medication works best when meals contain no more than approximately 15g of fat to minimise gastrointestinal side effects.
UK Online Prescription Process
Getting orlistat prescription online is straightforward. Complete our medical questionnaire covering your health history, current medications and weight management goals.

Your medication is then dispensed by our GPhC-registered pharmacy and delivered discreetly to your address with next day delivery available.
Who Can Use Prescription Orlistat?
Orlistat may be suitable for adults over 18 with obesity (BMI 30+) or those who are overweight (BMI 28+) with related health conditions. Suitability is assessed individually during your online consultation. The medication isn't suitable for pregnant or breastfeeding women, under-18s, or those with certain medical conditions including malabsorption syndrome or cholestasis.
Maximising Results with Orlistat
Orlistat works most effectively when combined with a structured approach to weight management. Keep dietary fat intake low (around 30% of daily calories), spread evenly across three meals. Take one capsule with each main meal containing fat, up to three times daily. A daily multivitamin is recommended as orlistat may reduce absorption of fat-soluble vitamins. Regular physical activity and ongoing dietary changes support long-term success.
