Vitrona Clinic serves patients exclusively in Ohio and Kentucky.

Vitrona Clinic may prescribe FDA-approved medications or compounded alternatives when clinically appropriate. Compounded medications are prepared by state-licensed pharmacies to meet individual patient needs; however, the FDA does not review compounded medications for safety, effectiveness, or quality before they are marketed. Clinical trials of FDA-approved GLP-1 medications demonstrated an average weight loss of 14.9% over 68 weeks. Individual results will vary. These results are based on studies of FDA-approved products and may not reflect outcomes with compounded formulations. Weight loss results require following a reduced-calorie meal plan and regular physical activity. Consult your healthcare provider to determine if this treatment is appropriate for you.
