Question

Quizplus · Accepted Answer

Controlled substances in the C-II category (such as opioids like oxycodone and hydrocodone, and stimulants like Adderall and Ritalin) require a physical, written prescription to be presented to the pharmacy in order to be filled. This is due to their high potential for abuse and addiction. They cannot be called in or electronically prescribed.
