About orlistat

Type of medicine Anti-obesity drug
Used for Treatment of obesity along with a reduced-calorie diet
Also called Xenical
Available as Capsules

Orlistat is not absorbed into the bloodstream, but works locally in the stomach and small intestine, where it prevents the action of two enzymes found in the digestive juices. These enzymes, called gastric and pancreatic lipases, normally break down fats that we consume in our diet.

Before taking orlistat

Before taking orlistat make sure your doctor or pharmacist knows:

  • If you are pregnant, trying for a baby or breast-feeding
  • If you suffer from chronic malabsorption syndrome (long term inability of the gut to absorb sufficient nutrients)
  • If you suffer from cholestasis (failure of the normal flow of bile from the liver to the intestines)
  • If you are taking a drug called ciclosporin

How to take orlistat

  • The recommended dose of orlistat is one 120 mg capsule taken with water immediately before, during or up to one hour after each main meal
  • If a meal is missed or contains no fat, there is no need to take the dose of orlistat

Getting the most from your treatment

  • You should eat a nutritionally balanced, low fat and reduced calorie diet
  • Your diet should be rich in fruit and vegetables
  • Your daily intake of fat, carbohydrate and protein should be distributed over three main meals
  • Since orlistat may interfere with the absorption of vitamins A, D, E and K, you may wish to take a multivitamin supplement; this should be taken at least two hours after orlistat or at bedtime
  • Your doctor will check your weight regularly, and depending on how much weight you lose, you may be able to continue treatment for up to one year

PS - Health and Poverty

Perhaps the biggest cause of ill health in the world is poverty. Help to Make Poverty History. For example, why not lend some of your money to disadvantaged communities to enable them to trade their way out of poverty through schemes such as Shared Interest.
