How Xenical Works and Treatment Options Available
How Does Xenical Work for Weight Loss?
Xenical contains orlistat 120mg, which works by blocking approximately one third of dietary fat from being absorbed in the digestive system. The medication inhibits lipase enzymes in the gut, causing unabsorbed fat to pass naturally through the body. Xenical acts locally in the digestive system rather than affecting the brain, making it different from appetite suppressants. Clinical studies show orlistat may help support weight management when used alongside a reduced-calorie, lower-fat diet and regular physical activity.
Xenical vs Generic Orlistat - Same Effect, Different Price
Both Xenical and generic orlistat contain identical 120mg doses of the same active ingredient. The clinical effect is equivalent - the key difference is cost. Generic orlistat 120mg costs £29.69 for 4 weeks with code EDM10, whilst branded Xenical costs £38.69 for the same period. Some patients prefer the reassurance of the original branded version, whilst others choose generic orlistat for better value. Your prescriber can help determine which option suits your needs and budget.
Treatment Options and Pricing
We offer three orlistat-based weight loss options following clinical assessment. Orlistat 120mg (generic) provides the most cost-effective choice from £15.20 for 2 weeks. Xenical 120mg offers the branded option from £19.35 for 2 weeks. Alli 60mg provides a lower-strength alternative from £26.09 for 4 weeks. All prices include 10% discount with code EDM10. Prescription consultations are included - no separate GP fees apply.
Who May Be Suitable for Xenical Treatment
Xenical may be suitable for 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. Treatment suitability is assessed individually through our online clinical questionnaire, reviewed by UK-licensed prescribers. Not everyone will be eligible - factors like pregnancy, breastfeeding, or certain medical conditions may affect suitability. The prescriber will determine whether Xenical is appropriate for your specific circumstances.
Online Prescription Process
Our streamlined process makes accessing Xenical convenient and discreet. Complete the online health questionnaire covering medical history and current medications. A qualified UK prescriber reviews your information and issues a prescription where clinically appropriate. Our GPhC-registered Leicester pharmacy dispenses your medication with next day delivery available. The entire process typically takes 24-48 hours from assessment to delivery, with prescription costs included in the price.
Important Safety Information
Like all prescription medicines, Xenical may cause side effects, most commonly gastrointestinal effects related to dietary fat intake. These include oily stools, increased bowel movements, and urgent need for the toilet. Side effects can be minimised by keeping fat intake low (approximately 15g per meal). A daily multivitamin is recommended as orlistat may reduce absorption of fat-soluble vitamins. Always follow your prescriber's guidance and report any persistent or severe side effects.
