Brand-name vs compounded

Prefest is an FDA-approved brand-name product. Many Kindr patients use compounded alternatives prepared by a state-licensed 503A pharmacy when a custom dose, custom combination, or different delivery form is clinically preferable. Both pathways are available through Kindr — your provider will recommend based on your individual needs.
