Prescription weight-loss drugs

Who can take weight-loss drugs?

Your healthcare professional may suggest a weight-loss medicine for you if you haven't been able to lose weight through diet and exercise and your:

  • Body mass index, also called BMI, is greater than 30. This means you have a condition that involves having too much body fat, called obesity.
  • BMI is greater than 27. And you also have a serious medical issue linked to weight, such as diabetes or high blood pressure.

Before choosing a medicine for you, your healthcare professional asks about your health history and health challenges. Then your healthcare professional talks with you about the pros and cons of prescription weight-loss drugs.

These medicines aren't for everyone. For example, you shouldn't take prescription weight-loss drugs if you're pregnant or breastfeeding or trying to get pregnant.
