Maryland PDMP

Maryland Prescription Drug Monitoring Program
The Prescription Drug Monitoring Program (PDMP) has been established by the Maryland Department of Health (MDH) to support healthcare providers and their patients in the safe and effective use of prescription drugs. The PDMP collects and securely stores information on drugs that contain controlled substances and are dispensed to patients in Maryland. Drug dispensers, including pharmacies and healthcare practitioners, electronically report the information that is stored in the PDMP database.

Access to prescription data is made available at no-cost to physicians, nurse practitioners, pharmacists and others who provide pharmaceutical care to their patients. By law, healthcare providers may only access information on patients under their care. Use of prescription information improves providers’ ability to manage the benefits and risks of controlled substance medications and identify potentially harmful drug interactions.

The PDMP also assists agencies responsible for ensuring public health and safety through the investigation of illegal or inappropriate prescribing, dispensing or use of prescription drugs. Investigators must register with the PDMP and may only request data to support an existing investigation, typically supported by a subpoena for the information.

Lastly, the PDMP supports research and educational initiatives designed to broaden public understanding of prescription drug abuse and develop more effective approaches to addressing this serious personal and public health challenge.

Information specific to healthcare providers, patients, agency personnel and the general public is available on this website. If you have additional questions, please contact the PDMP by email or telephone.
