Frequently asked questions
What does off-label mean?
An approved drug used for a purpose, dose, or form not listed in its FDA labeling. Clinicians may prescribe off-label when supported by evidence and clinically appropriate.
Is a compounded version the same as the FDA-approved product?
No. Compounded medications are not FDA-approved, have not been reviewed by the FDA for safety, effectiveness, or quality, and are not equivalent to approved products. They may only be prescribed when legally permitted and clinically appropriate.
