What is Orlistat?

Orlistat is the generic, low cost version of the weight loss medication Xenical. Orlistat is a drug that is designed to treat obesity. Like other weight loss pills, it blocks some of the fat you eat from being absorbed by your body. Orlistat should be taken alongside a reduced-calorie diet. When taken alongside a reduced-calorie diet, Orlistat can help you lose up to 50% more weight.

How does Orlistat work?

Orlistat, like other weight loss tablets,  works by preventing your body from absorbing 50% of the fat molecules you ingest.


Fat Absorption without Orlistat

Fat is too large to be absorbed by our body

It is broken down by enzymes into smaller parts that our body can absorb


The smaller molecules are easily absorbed in our body

Fat Absorption with Orlistat: only 50% of fat is absorbed by the body

When you take Xenical with a well-balanced diet, it blocks some of the enzymes from breaking down the fat

Larger fat molecules can therefore not be absorbed by the body and are excreted


How do you take Orlistat?

Always take this medication as directed by your doctor of pharmacist.


Take one capsule three times a day. Orlistat can be taken with or without food.


For optimal benefits, while taking Orlistat you should avoid eating fatty foods

How effective is Orlistat?

Orlistat can effectively help you lose up to 50% more weight when taken alongside a reduced-calorie diet. In addition to dieting and taking Orlistat, in order to lose weight you should increase your exercise.

What are the main side effects of Orlistat?

Like all medicines, Orlistat can cause side effects, although not everyone experiences them. The most common side effects of Orlistat are:

  • Headache
  • Abdominal pain or discomfort
  • Urgent or increased need to open the bowels


For less frequent side effects, please see the patient information leaflet.
