NICE guidance - orlistat for the treatment of obesity

Last reviewed 05/2021

Summary points of the guidance on the use of orlistat for the treatment of obesity in adults:

  • orlistat should be prescribed only as part of an overall plan for managing obesity in adults who meet one of the following criteria:
    • a BMI of 28.0 kg/m2 or more with associated risk factors
    • a BMI of 30.0 kg/m2 or more
  • therapy should be continued beyond 3 months only if the person has lost at least 5% of their initial body weight since starting drug treatment
  • the decision to use drug treatment for longer than 12 months (usually for weight maintenance) should be made after discussing potential benefits and limitations with the patient
  • the coprescribing of orlistat with other drugs aimed at weight reduction is not recommended

Notes:

  • rates of weight loss may be slower in people with type 2 diabetes, so less strict goals than those for people without diabetes may be appropriate. These goals should be agreed with the person and reviewed regularly
