Why Your Orlistat May Not Be Working as Expected
Understanding Why Orlistat Effectiveness May Change
Orlistat works by blocking approximately one third of dietary fat absorption in your digestive system. However, several factors can influence whether orlistat continues to support your weight management goals effectively over time.
The most common reason orlistat appears to "stop working" is dietary changes. If your fat intake per meal increases above 15g, you may experience more side effects but not necessarily better weight management results. Conversely, if your diet becomes very low in fat, orlistat has less fat to block, which may affect its contribution to your overall calorie reduction.
Factors That Influence Orlistat Effectiveness
Your body doesn't become "resistant" to orlistat like some medications, but your weight loss journey naturally progresses through different phases. Initial weight loss may be more noticeable, while long-term weight management requires sustained dietary and lifestyle changes alongside your prescription treatment.
At EverydayMeds, our generic orlistat 120mg starts from £29.69 for a 4-week supply (84 capsules) with code EDM10, while branded Xenical 120mg costs £38.69 for the same period. Both contain identical active ingredients and work in exactly the same way.
Getting the Most From Your Prescription Treatment
Orlistat may help support weight management when you maintain a reduced-calorie, lower-fat diet with no more than 30% of daily calories from fat. Taking a daily multivitamin at bedtime (at least 2 hours after your last orlistat dose) helps maintain nutrition while the medication reduces fat-soluble vitamin absorption.
If you feel your current treatment isn't supporting your goals, our UK-licensed prescribers can review your progress through a confidential online consultation. They may recommend adjusting your approach or exploring whether you're still suitable for continued treatment.
Prescription Orlistat vs Alli: Choosing Your Strength
Prescription orlistat 120mg and Xenical 120mg offer the full clinical dose, while Alli 60mg provides a lower-strength option. Our 12-week supply of orlistat 120mg (252 capsules) costs £86.39 with EDM10, compared to £116.99 for Alli's equivalent supply.
The higher strength may be more suitable if you've been using Alli without achieving your desired results, subject to prescriber approval following clinical assessment.
