Choose Your Orlistat Pack Size and Manage Side Effects
Understanding Orlistat and Gastrointestinal Side Effects
Orlistat may cause gastrointestinal side effects including loose stools, oily discharge, and increased bowel movement frequency. These effects occur because orlistat blocks approximately one third of dietary fat absorption, and unabsorbed fat passes naturally through the digestive system. The severity of side effects is directly linked to the fat content of your meals - keeping fat intake low (around 15g per meal) significantly reduces these symptoms.
Orlistat 120mg Pack Sizes and Pricing
Our generic orlistat 120mg is available in flexible pack sizes: 2-week supply (42 capsules) for £15.20 with EDM10, 4-week supply (84 capsules) for £29.69, 8-week supply (168 capsules) for £57.59, or 12-week supply (252 capsules) for £86.39. Starting with a smaller pack allows you to assess tolerance before committing to longer treatment periods. Longer packs offer better value - the 12-week supply saves over £20 compared to buying six 2-week packs.
Xenical 120mg Branded Options
Prefer branded Xenical? Available in the same pack sizes: 2-week supply for £19.35 with EDM10, 4-week supply for £38.69, 8-week supply for £78.29, or 12-week supply for £116.09. Xenical contains identical active ingredients to generic orlistat at the same 120mg dose, providing the same clinical effect. Both options require prescription following online clinical assessment by our UK-licensed prescribers.
Alli 60mg Lower-Dose Alternative
Alli 60mg offers a gentler introduction with typically milder side effects. Available in 4-week supply (42 capsules) for £26.09 with EDM10, 8-week supply (84 capsules) for £49.49, or 12-week supply (252 capsules) for £116.99. The lower dose blocks a smaller proportion of dietary fat, which may result in fewer gastrointestinal effects while still supporting weight management alongside a reduced-calorie, lower-fat diet.
Managing Side Effects During Treatment
Most patients find gastrointestinal side effects reduce as they adapt their diet and the body adjusts to treatment. Wearing dark underwear or panty liners during initial weeks can help manage any minor leakage. Taking a multivitamin at bedtime (at least 2 hours after your last orlistat dose) helps maintain fat-soluble vitamin levels. If side effects are severe or persistent, consult your healthcare professional about adjusting your treatment plan.
