DEA Revokes Dr. Hayriye Gok’s Registration to Handle Controlled Substances in Pennsylvania
Estimated reading time: 3–5 minutes
On July 9, 2025, the Drug Enforcement Administration (DEA) announced it has revoked the Certificate of Registration for Hayriye Gok, M.D., of Philadelphia, Pennsylvania. This certificate allowed Dr. Gok to handle controlled substances in the state.
The action came after the DEA issued an Order to Show Cause (OSC) against Dr. Gok on February 20, 2025. The DEA stated that Dr. Gok could not legally handle controlled substances in Pennsylvania because her state license to practice medicine had been suspended.
Dr. Gok was notified about the OSC and was informed she had the right to ask for a hearing. She did not request a hearing. According to the DEA, when a person does not ask for a hearing, they are considered to have admitted the facts listed in the OSC.
The DEA tried to reach Dr. Gok at her business address and by phone, but was not successful. The DEA then served the OSC to Dr. Gok by email. Dr. Gok replied and confirmed she received the notice, but she still did not ask for a hearing.
The DEA checked Pennsylvania’s official online license records. As of the date of the order, Dr. Gok’s medical license showed a “Suspension” status. The Pennsylvania State Board of Medicine had temporarily suspended her license on November 21, 2024.
The DEA orders are based on federal law. This law says that a physician must have a valid state license to get and keep a DEA registration to dispense controlled substances. Without a license, a doctor is not allowed to prescribe, administer, or handle these drugs.
In Pennsylvania, a practitioner must be licensed or otherwise allowed to give out or prescribe a controlled substance. With Dr. Gok’s license suspended, she is not allowed to practice medicine or handle controlled substances in Pennsylvania.
The DEA’s order also says that any pending applications by Dr. Gok to renew or change her registration, or to get a new registration in Pennsylvania, are denied.
The DEA’s action is final and goes into effect on August 8, 2025.
The order was signed by Acting Administrator Robert J. Murphy on July 1, 2025, and published in the Federal Register. Heather Achbach, the DEA Federal Register Liaison Officer, completed the filing for official publication.
