Hello. I Recieve My ADHD Prescription By Mail. Not The

Hello. I recieve my ADHD Prescription by mail. Not the actual pills - but the paper prescription. What are my options in the event that this prescription gets lost in the mail? Is it possible to have a new one written? Again - I did not lose the pills themselves - only the paper presciption. Is there a way for the doctor to verify that the prescription was never filled and write a new one? Thank you for your help.
