Choose Your Orlistat Supply Length - Manage Side Effects
Understanding Orlistat's Digestive Side Effects
Orlistat works by blocking approximately one third of dietary fat absorption, which can cause gastrointestinal side effects including flatulence, oily stools, and urgent bowel movements. These effects are directly related to fat intake - keeping meals to around 15g fat reduces symptoms significantly.
2-Week Supply: Test Your Tolerance
Starting with a 2-week supply allows you to assess how your body responds to orlistat. Our generic orlistat 120mg costs £16.89 (£15.20 with EDM10), whilst branded Xenical 120mg is £21.50 (£19.35 with EDM10). This shorter supply is ideal for first-time users concerned about digestive side effects like wind and oily discharge.
4-Week Supply: Most Popular Choice
The 4-week supply provides the optimal balance of commitment and flexibility. Generic orlistat 120mg costs £32.99 (£29.69 with EDM10), offering better value than 2-week packs. Xenical 120mg 4-week supply is £42.99 (£38.69 with EDM10). Most patients find digestive side effects settle within 2-4 weeks of consistent treatment.
8-Week Supply: Better Value for Established Users
Once you've established tolerance, 8-week supplies offer significant savings. Generic orlistat 120mg costs £63.99 (£57.59 with EDM10) - equivalent to £7.20 per week. Xenical 120mg is £86.99 (£78.29 with EDM10). Alli 60mg 8-week supply costs £54.99 (£49.49 with EDM10) for those preferring lower-strength treatment.
12-Week Supply: Maximum Savings
Our best-value option provides 12 weeks of treatment. Generic orlistat 120mg costs £95.99 (£86.39 with EDM10), saving over £40 compared to buying six 2-week supplies. Xenical 120mg is £128.99 (£116.09 with EDM10). This supply length is recommended for established patients comfortable with their response to treatment.
Managing Flatulence and Digestive Effects
Wind and oily discharge occur because unabsorbed fat passes through your digestive system. These effects can be minimised by following a reduced-calorie, lower-fat diet. Spreading daily fat intake across three meals (maximum 15g fat per meal) significantly reduces digestive side effects including excessive flatulence.
Lower-Strength Alli Option
For those concerned about side effects, Alli 60mg provides half the dose of prescription-strength orlistat. Available in 4-week (£28.99/£26.09 with EDM10), 8-week (£54.99/£49.49 with EDM10), and 12-week (£129.99/£116.99 with EDM10) supplies, Alli typically causes milder digestive effects whilst still supporting weight management.
