§ 11158 Controlled Substance Prescription Requirements

Key Takeaways

  • •You need a prescription from a doctor to get strong medicines like painkillers or ADHD drugs (Schedule II).
  • •Doctors can give you a small amount (up to 3 days' worth) of these strong medicines in emergencies, like if you're in bad pain or starting addiction treatment.
  • •Doctors can give you these medicines directly in a hospital or clinic without a prescription, but only for a short time.
  • •Weaker medicines (Schedule III, IV, or V) also need a prescription, unless a doctor gives them to you directly.

Example

You break your arm and go to the emergency room. The doctor gives you strong pain medicine right away.

The doctor can give you up to 3 days' worth of painkillers without a prescription because you're in bad pain and need help fast. After that, you'd need a prescription to get more.
