These instructions apply only to Physician’s Assistants.

General Information

  • If you don’t already have prescriptive authority when you file this CSR application, you should receive your CSR 3-4 weeks after your prescriptive authority is approved. Please allow the 3-4 weeks to elapse before calling the office.
  • Your Delaware CSR certificate and all CSR-related correspondence must be mailed to the same address as your PA license.
  • You need only one Delaware CSR to prescribe controlled substances in Delaware even if you prescribe controlled substances at more than one Delaware business/practice or more than one location of a business/practice. However, every Delaware location where controlled substances are dispensed/stored must be covered by a CSR. If no other practitioner (e.g., physician), physician assistant or APN holds a Delaware CSR for a location where you will store/dispense , as well as prescribe, controlled substances, you must file for an additional CSR for the location in Question 13 of the application.
  • When your Delaware CSR is approved, you must then file for a federal DEA registration for Delaware.  You must have both a Delaware CSR and DEA registration for Delaware before you prescribe controlled substances in Delaware.  A DEA registration in another jurisdiction is not sufficient for prescribing controlled substances in Delaware.
  • Delaware law prohibits, with few exceptions, prescribing of controlled substances to patients in Delaware via the internet or telemedicine. You may contact the Office of Controlled Substances if you wish to discuss this matter.

Requirements for All Applicants

  • Enclose processing fee by check or money order made payable to “State of Delaware.” The total fee depends on how many controlled substance registrations you are applying for. Multiply the fee on the Fee Schedule by the number of registrations applied for in Question 2 of the application (not the controlled substance schedule in Question 6).
  • Arrange for your main supervising Physician and for all alternate supervising Physicians to complete and sign the boxes in the SUPERVISION section.
