Understanding Orlistat Side Effects Before You Buy

Does Orlistat Cause Diarrhoea and Digestive Changes?

Orlistat may cause changes to bowel movements, including loose stools, as part of how the medication works. When orlistat blocks approximately one third of dietary fat from being absorbed, this unabsorbed fat passes naturally through your digestive system. Common digestive effects include oily or fatty stools, increased frequency of bowel movements, and urgent need to use the toilet. These side effects are more likely when eating high-fat meals and can be significantly reduced by following a lower-fat diet with approximately 15g fat per meal.

Minimising Digestive Side Effects

The key to reducing digestive side effects is maintaining a reduced-calorie, lower-fat diet whilst taking orlistat. Spreading your daily fat intake evenly across three main meals and keeping each meal to around 15g of fat helps minimise uncomfortable symptoms. Most patients find side effects reduce over time as they adapt their diet. Our prescribers provide detailed dietary guidance alongside your orlistat prescription to help you manage treatment effectively.

Orlistat 120mg Prescription Options

Choose between cost-effective generic orlistat 120mg or branded Xenical 120mg - both contain identical active ingredients. Generic orlistat offers excellent value starting at £32.99 for a 4-week supply (84 capsules), or £29.69 with EDM10. Xenical 120mg costs £42.99 for the same 4-week supply, or £38.69 with discount. Both options require the same online clinical assessment by our UK-licensed prescribers. For those preferring lower-strength treatment, Alli 60mg is available at £28.99 for 4 weeks.

Professional Weight Loss Support

Our online clinical assessment ensures orlistat is suitable for your individual circumstances. UK-licensed prescribers review your medical history, current medications, and weight management goals before issuing a prescription. Treatment may be appropriate for adults with a BMI of 30 or above, or 28 and above with weight-related health conditions like diabetes or high blood pressure. The prescription is included in your order price - no separate GP appointment needed.
