Ozempic and Wegovy are both brand names for the drug semaglutide, but they are used for different purposes and have different dosages. Ozempic is primarily used to improve blood sugar control in adults with type 2 diabetes. It is not used for the treatment of type 1 diabetes or diabetic ketoacidosis. Ozempic is an injectable medication that is typically taken once a week. The starting dose is usually 0.25 mg per week for 4 weeks, then increased to 0.5 mg per week. If additional blood sugar control is needed, the dose can be increased to 1 mg per week. While Wegovy is used for chronic weight management in adults who are obese or overweight and have at least one weight-related condition (such as high blood pressure, type 2 diabetes, or high cholesterol), in addition to a reduced calorie diet and increased physical activity. Wegovy is also an injectable medication, but it's used at a higher dose than Ozempic. The starting dose is 0.25 mg per week, increased gradually over 16 weeks to a maintenance dose of 2.4 mg per week. Both medications work by mimicking a hormone in your body (GLP-1) that targets areas of the brain that regulate appetite and food intake, and they also help your body to produce more insulin when needed. However, they are not interchangeable and should be used as directed by a healthcare provider.
