How Fat Blocker Orlistat Works for Weight Loss
Orlistat is a prescription weight loss medication that works by blocking approximately one third of the fat you eat from being absorbed by your body. This lipase inhibitor acts locally in your digestive system, preventing enzymes from breaking down dietary fat. The unabsorbed fat passes naturally through your body, which may help reduce your calorie intake when combined with a reduced-calorie, lower-fat diet and regular physical activity.
Prescription Orlistat Options Available
EverydayMeds offers three fat blocker options following clinical assessment. Generic orlistat 120mg provides the most cost-effective prescription strength treatment from £15.20 for 2 weeks (£29.69 for 4 weeks with EDM10). Branded Xenical 120mg contains the identical active ingredient at £19.35 for 2 weeks (£38.69 for 4 weeks with EDM10). For those preferring lower-strength treatment, Alli 60mg is available from £26.09 for 4 weeks with code EDM10. All options require assessment by our UK-licensed prescribers.
Who May Be Suitable for Fat Blocker Treatment
Prescription orlistat may be suitable for adults with a BMI of 30 or above, or BMI of 28 or above with weight-related health conditions such as type 2 diabetes or high blood pressure. Our prescribers will assess your individual circumstances, medical history, and weight management goals during the online consultation. Treatment must always be used alongside dietary changes and increased physical activity for optimal support.
Managing Your Fat Blocker Treatment
Take one capsule with each main meal containing fat, up to three times daily. Keep meals low in fat (approximately 15g per meal) to minimise gastrointestinal side effects while maximising the treatment's effectiveness. Most patients find side effects reduce as they adapt to a lower-fat diet. A daily multivitamin taken at bedtime is recommended to ensure adequate fat-soluble vitamin intake.
