Understanding Alli Weight Loss Dosage and Prescription Options
Prescription weight loss treatment in the UK includes three orlistat-based options, each with specific dosage requirements. Orlistat 120mg and Xenical 120mg require one capsule three times daily with each main meal containing fat, whilst Alli 60mg follows the same schedule at half the prescription strength. Following clinical assessment by UK-licensed prescribers, these treatments may help support weight management alongside a reduced-calorie, lower-fat diet by blocking approximately one third of dietary fat absorption.
Orlistat 120mg - Most Cost-Effective Option
Generic orlistat 120mg offers prescription-strength weight loss treatment at the best value. Available from £15.20 for 2 weeks (42 capsules) with EDM10 discount, extending to £86.39 for 12 weeks (252 capsules). This clinically equivalent alternative to branded Xenical contains the same active ingredient at identical dosage, prescribed following individual assessment for adults with BMI 30+ or BMI 28+ with weight-related health conditions like type 2 diabetes or high blood pressure.
Xenical 120mg - Branded Prescription Treatment
Xenical represents the original branded orlistat treatment, available from £19.35 for 2 weeks with EDM10 code. Manufactured by Roche, Xenical 120mg delivers identical clinical effects to generic orlistat but at premium pricing. Many patients choose Xenical for brand familiarity, whilst others prefer generic orlistat for cost savings of approximately £9 monthly. Both require prescription following clinical assessment and work through the same lipase inhibition mechanism.
Alli 60mg - Lower Strength Alternative
Alli provides orlistat at 60mg strength - half the prescription dose but following the same three-times-daily schedule with main meals. Priced from £26.09 for 4 weeks (42 capsules) with EDM10 discount, Alli may suit those preferring lower-strength starting treatment. The reduced dose typically produces milder gastrointestinal effects whilst still supporting weight management through partial dietary fat blocking when combined with appropriate diet modification.
How Prescription Weight Loss Treatment Works
All orlistat-based treatments work by inhibiting lipase enzymes in the digestive system, preventing approximately one third of dietary fat from being absorbed. This unabsorbed fat passes naturally through the body, potentially reducing calorie intake from fat sources. The mechanism acts locally in the gut rather than systemically, making it different from appetite suppressants. Treatment effectiveness depends heavily on maintaining reduced-fat meals - typically 15g fat per meal - to maximise benefits and minimise side effects.

Treatment Suitability and Safety
Prescription weight loss treatment may be suitable for adults with BMI 30+ or BMI 28+ with weight-related conditions, subject to individual clinical assessment. Treatment works best alongside structured dietary changes, emphasising reduced-calorie, lower-fat eating patterns and increased physical activity. Common side effects are gastrointestinal and directly related to dietary fat intake - maintaining low-fat meals significantly reduces these effects. Always follow prescriber guidance and report persistent or severe side effects promptly.
