Orlistat weight loss
A prescription tablet that reduces the amount of fat your body absorbs from food, supporting steady weight loss alongside a reduced-calorie diet. Our pharmacist-led consultation will check whether Orlistat is suitable for you.
Orlistat works alongside a healthy eating plan, not in place of one. The patients who see the best results are those using it as part of a broader change — and we're here to help you build it.
Orlistat is a prescription tablet taken three times a day with your main meals.
It blocks around 30% of the fat in your meals from being absorbed, helping you lose weight alongside a low-fat diet.
Our pharmacist will talk you through dietary tips to maximise results and minimise side effects.

Frequently asked questions
The most common questions about Orlistat and how our weight loss service works. Need more detail? Get in touch with our pharmacy team.
Orlistat blocks around 30% of the fat in your meals from being absorbed by your body. The unabsorbed fat passes through your digestive system naturally, helping you lose weight when combined with a low-fat, reduced-calorie diet.
Clinical studies show an average weight loss of 5–10% of starting body weight over 6–12 months when Orlistat is combined with a reduced-calorie, low-fat diet and regular exercise.
Side effects are mostly digestive — oily or fatty stools, urgent bowel movements, flatulence and occasional leakage. These are usually more pronounced if you eat high-fat meals.
Yes — a reduced-calorie, low-fat diet is essential. Each meal should contain no more than 30% fat to avoid side effects and help Orlistat work effectively. Our pharmacist will provide detailed dietary guidance.
Orlistat can reduce absorption of some medications, including the contraceptive pill (especially if you have diarrhoea), some anti-epileptics and thyroid hormones. Always tell your pharmacist about every medication and supplement you're taking.
