Orlistat 120mg vs Alli 60mg: Making Your Choice
Understanding Your Prescription Weight Loss Options
When considering prescription weight loss treatment, you have three main options: generic orlistat 120mg, branded Xenical 120mg, and Alli 60mg. All contain the same active ingredient - orlistat - which works by blocking approximately one third of dietary fat absorption. The key differences lie in strength, prescription requirements, and cost.
Orlistat 120mg: Maximum Prescription Strength
Generic orlistat 120mg offers the strongest available dose, requiring a prescription following clinical assessment. At £32.99 for a 4-week supply (£29.69 with EDM10), it provides excellent value for prescription-strength treatment. This option may help reduce the amount of dietary fat absorbed when used alongside a reduced-calorie, lower-fat diet. Our UK-licensed prescribers assess your suitability through an online consultation, making treatment accessible without GP appointments.
Xenical 120mg: The Branded Alternative
Xenical contains identical orlistat 120mg to the generic version but costs £42.99 for 4 weeks (£38.69 with EDM10). Made by Roche, some patients prefer the branded option, though the clinical effect remains the same. Both prescription-strength options require the same online clinical assessment and can support weight management when combined with dietary and lifestyle changes.
Alli 60mg: Lower-Strength Option
Alli provides half the strength of prescription orlistat at 60mg per capsule. At £54.99 for 8 weeks (£49.49 with EDM10), it offers a lower-strength starting point. Whilst still clinically effective, the reduced dose blocks a smaller proportion of dietary fat compared to 120mg options. This may result in fewer gastrointestinal side effects for some patients.
Which Treatment May Suit You Best?
Your choice depends on individual circumstances assessed during consultation. Prescription orlistat 120mg offers maximum strength at the lowest cost, particularly with EDM10 discount. Patients requiring stronger intervention often benefit from 120mg options, whilst those preferring gentler treatment may consider Alli 60mg. All options work best when fat intake is kept low - approximately 15g per meal - to minimise side effects and maximise effectiveness.
