Start Your Weight Loss Journey with Orlistat Today
How Quickly Does Orlistat Begin Working?
Orlistat starts working immediately after taking your first capsule. The medication acts locally in your digestive system, inhibiting lipase enzymes that break down dietary fat. Within hours of your first dose, orlistat begins blocking approximately one third of the fat you eat from being absorbed into your body. This unabsorbed fat passes naturally through your digestive system.
What to Expect in Your First Week
During your first week taking orlistat 120mg, you may notice gastrointestinal effects that indicate the medication is working. These effects are more noticeable when eating higher-fat meals. To minimise side effects, keep your fat intake to approximately 15g per meal. Most patients find these effects reduce as they adapt to a lower-fat diet.
Choose Your Orlistat Treatment Option
We offer three clinically effective options: Generic orlistat 120mg from £15.20 (2-week supply with EDM10), branded Xenical 120mg from £19.35 (2-week supply with EDM10), or Alli 60mg from £26.09 (4-week supply with EDM10). All contain the same active ingredient and work through the same fat-blocking mechanism.

Clinical Assessment Process
Our UK-licensed prescribers assess your suitability through a comprehensive online consultation. Orlistat may be suitable for adults with a BMI of 30kg/m² or above, or 28kg/m² or above with weight-related health conditions. Following clinical approval, your prescription is dispensed by our GPhC-registered pharmacy and delivered discreetly to your address.
Supporting Your Weight Management Goals
Orlistat works best as part of a structured weight management programme. The medication may help reduce calorie intake from dietary fat while you maintain a reduced-calorie, lower-fat diet and increase physical activity. Take one 120mg capsule with each main meal containing fat, up to three times daily. Individual responses vary, but the fat-blocking action begins immediately.
