Orlistat vs Xenical: How Long Do They Take to Work?

pricing for mounjaro and wegovy weight loss

Orlistat 120mg and Xenical 120mg contain identical active ingredients and work in exactly the same way - the key difference is price. Both begin blocking approximately one third of dietary fat from your first dose, with effects typically noticed within 1-2 days when combined with a reduced-calorie, lower-fat diet. Generic orlistat costs from £15.20 for a 2-week supply, while branded Xenical costs from £19.35 - you could save over £25 per 12-week course by choosing orlistat. Both require clinical assessment by a UK-licensed prescriber. Use code EDM10 for 10% off your order at EverydayMeds.

Choose Generic Orlistat or Branded Xenical - Same Results

How Quickly Do Orlistat and Xenical Start Working?

Both orlistat 120mg and Xenical 120mg begin working immediately from your first capsule. The active ingredient orlistat starts blocking lipase enzymes in your digestive system within hours, preventing approximately one third of dietary fat from being absorbed. Most patients notice gastrointestinal effects within 1-2 days of starting treatment, particularly when eating meals containing fat. These effects indicate the medication is working as intended.

Orlistat vs Xenical: Identical Mechanism, Different Price

The only meaningful difference between generic orlistat 120mg and branded Xenical 120mg is cost. Both contain exactly the same active ingredient at the same dose and work through the identical mechanism - inhibiting lipase enzymes in your gut to block fat absorption. At EverydayMeds, orlistat costs £29.69 for a 4-week supply (with code EDM10) while Xenical costs £38.69 - that's £9 extra per month for the same clinical effect. Over a 12-week course, choosing generic orlistat saves you £29.70 compared to Xenical.

Current EverydayMeds Pricing Comparison

Generic orlistat 120mg: 2-week supply £15.20, 4-week supply £29.69, 8-week supply £57.59, 12-week supply £86.39 (all prices with EDM10). Branded Xenical 120mg: 2-week supply £19.35, 4-week supply £38.69, 8-week supply £78.29, 12-week supply £116.09 (all prices with EDM10). Both options require the same online clinical assessment and are dispatched from our GPhC-registered pharmacy with next day delivery available.

Consider Alli 60mg for Lower-Strength Option

If you prefer starting with a lower dose, Alli 60mg contains half the strength of prescription orlistat. While clinically less potent than the 120mg versions, Alli may suit those wanting a gentler introduction to orlistat treatment. Alli costs £26.09 for a 4-week supply with code EDM10. All three products work through the same fat-blocking mechanism and should be taken with a reduced-calorie, lower-fat diet.

Online Prescription Process for Both Products

Whether you choose orlistat or Xenical, the prescription process remains identical. Complete our online health questionnaire covering your medical history, current medications, and BMI information. A UK-licensed prescriber reviews your assessment and issues a prescription where clinically appropriate. Your chosen medication is then dispensed by our Leicester-based GPhC-registered pharmacy and dispatched discreetly to your address. Use code EDM10 at checkout for 10% off every order.
