Prescription medication may be a useful addition for managing obesity.
Expected weight loss in 1 year is about 2.9% – 6.0% of your overall body weight.1,2
How well does pharmacotherapy work?
Clinical studies of drug therapies have shown average weight loss of between 3% and 12% of baseline bodyweight; an outcome strongly influenced by individual physiology.1
In order to take medications for more than three months, you must lose at least 5% of your starting weight within 12 weeks of commencing the maximum recommended dose.3,4
In clinical studies, 50–68% of people achieved this required weight loss.3,4 If you have not lost at least 5% of your starting weight in three months or you need to lose more, your doctor will discuss additional options with you.1
