Description
Foundayo (orforglipron) is an oral prescription tablet used with a reduced-calorie diet and increased physical activity for chronic weight management in adults. It is prescribed for adults with obesity, or for adults who are overweight and have at least one weight-related health condition such as high blood pressure, high cholesterol, or type 2 diabetes.
Foundayo belongs to a class of medications called GLP-1 receptor agonists. It works by mimicking a natural hormone that regulates appetite and digestion, reducing hunger, increasing feelings of fullness, and slowing the rate at which the stomach empties. Together, these effects help patients eat less and maintain weight loss over time.
Unlike some other oral weight loss medications, Foundayo can be taken at any time of day, with or without food, and without any water restrictions.
