What is Xenical?

How does Xenical work?

Xenical, or Orlistat in its generic form, works by reducing the amount of fat absorbed from your diet; it is not an appetite suppressant.

When fat enters the body, it is broken down by enzymes called lipases so that the body can digest it. Xenical (Orlistat) attaches itself to these enzymes so they cannot break down the fat. This stops about one third of the fat from your meal from being absorbed, allowing your body to pass the fat rather than store it.

The undigested fat then passes through your digestive system with no unwanted effects on your heart rate or sleeping pattern. Orlistat has been tested in hundreds of clinical studies and has proven to be very safe and effective.

Xenical (Orlistat) should only be used by those who are medically obese: people with a BMI of 30 or above, or a BMI of 28 or above with other risk factors such as diabetes or hypertension.

How should I take Xenical?

One 120mg capsule can be taken up to three times per day—just before, with a meal or up to one hour afterwards.
Do not take more than three capsules a day.
Swallow each capsule whole with water.
Take a multivitamin a couple of hours after Xenical or at bedtime to help maintain levels of vitamins A, D, E and K. Xenical can reduce the absorption of these fat-soluble vitamins.
Do not take Xenical if you miss a meal or the meal contains no fat.
You should see a reduction of around 5% of your body weight within the first 12 weeks. If you have not seen results within this time, Xenical may not be suitable for you.
Follow a calorie-controlled diet and exercise regularly. Your diet should be nutritionally balanced and contain no more than around 30% of its calories from fat. High-fat meals may make side effects worse.
