Which Should You Choose: Generic Orlistat or Xenical?
Orlistat vs Xenical: Identical Side Effect Profiles
Both generic orlistat 120mg and branded Xenical 120mg contain exactly the same active ingredient at the same dose. This means the likelihood of feeling sick is identical between both products. Nausea is a common side effect that may affect up to 1 in 10 people taking either medication. The key to minimising nausea is keeping your fat intake low - approximately 15g fat per meal. High-fat meals significantly increase your risk of gastrointestinal side effects including nausea.
Cost Comparison: Generic Orlistat vs Xenical
Generic orlistat offers substantial savings compared to branded Xenical. A 4-week supply of generic orlistat costs £32.99 (£29.69 with EDM10) versus Xenical at £42.99 (£38.69 with EDM10). Over 12 weeks, you save £30 choosing generic orlistat at £86.39 versus Xenical at £116.09. Both deliver identical clinical effects, so choosing generic orlistat makes financial sense without compromising effectiveness.
Managing Nausea with Orlistat
Whether you choose generic orlistat or Xenical, you can reduce nausea by following dietary guidelines. Take each 120mg capsule with meals containing fat, but keep fat content low. Spread your daily fat intake evenly across three main meals, avoiding high-fat snacks. If you experience persistent nausea, consult your healthcare professional. Remember that gastrointestinal side effects indicate the medication is working by blocking approximately one third of dietary fat absorption.
Alli 60mg: Lower Strength Alternative
If you're concerned about side effects, Alli 60mg offers half the dose of prescription-strength orlistat. At 60mg, Alli typically causes milder side effects including less nausea, though it's also clinically less potent. Alli costs £26.09 for a 4-week supply with EDM10. You can start with Alli to assess tolerance before considering prescription-strength options.
