Medical Toxicology within the University of Arizona Department of Emergency Medicine is committed to excellence in medical education, patient care, and scholarship. Our faculty physicians provide medical direction for the Arizona Poison and Drug Information Center and are available for bedside consultation at both Banner - University Medical Center South (BUMCS) and Banner - University Medical Center Tucson (BUMCT). We lead the required medical toxicology rotation for emergency medicine residents and are frequently asked to lecture locally, nationally, and internationally.

The Medical Toxicology Fellowship is a two-year program based at BUMCS campus, a 150-bed tertiary care hospital and Level 1 psychiatric facility with more than 48,000 emergency department visits annually. Medical toxicology also consults at BUMCT campus, the largest tertiary care hospital with more than 500 beds and the only Level I trauma center in Southern Arizona. BUMCT campus has more than 71,000 emergency department visits annually including more than 20,000 pediatric emergency department visits. Medical Toxicology has an out-patient clinic (Toxic Exposures Clinic) that serves both adults and children at BUMCS. Fellows will work closely with the Arizona Poison and Drug Information Center and the Toxic Exposures Clinic. The didactic curriculum includes lectures, conferences, and formal coursework at the UArizona Colleges of Medicine, Pharmacy, and Public Health. The didactic curriculum is based on the American Board of Emergency Medicine's 2012 Core Content of Medical Toxicology.

Mission Statment: To advance the research, education, exposure prevention, and clinical care of patients exposed to medications; performance-enhancing substances; dietary supplements; drug of abuse; natural toxins; envenomations; and environmental & occupational hazards, including pollutants, and to improve patient and public health, as well as to alleviate suffering from these exposures.


1) To train physicians, advancing their knowledge of preventive measures, processes, devices, and medications to treat exposures to natural and synthetic chemical hazards.

2) To train physicians, making them well versed in the effects of chemical exposures in humans and prepare them to give state-of-the-art treatment to patients suffering from chemical exposures, adverse drug effects, medication overdoses, interactions of chemicals, environmental and occupational exposures, use of chemicals for mind-altering effects or physical enhancement, withdrawal syndromes, and envenomations.

3) To train physicians to apply public health measures, including using poison and drug information centers, pharmacovigilance, toxicovigilance, and collaboration with public health agencies, as well as developing public health regulations and policies to mitigate and minimize the hazardous effects of natural toxins and synthetic toxicants in human populations.

4) To expand knowledge in the field of medical toxicology through research and publications in toxicovigilance, poison center electronic health record data analysis, clinical trials, institutional review board processes, and hypothesis producing case reports or case series.

5) To train physicians that have integrity, accountability, and commitment to excellence in their professional lives.

6) To provide an atmosphere of respect, compassion, collaboration, and diversity of people and thought.

The board-certified medical toxicologists have held multiple leadership positions in the American Academy of Clinical Toxicology, the American College of Medical Toxicology, the Medical Toxicology Subboard of the American Boards of Emergency Medicine, Preventive Medicine, and Pediatrics. We are committed to both education and research, with a special emphasis on envenomations, withdrawal, occupational exposures, and preparedness. The international headquarters for the Advanced Hazmat Life Support course is based here and is co-sponsored by the Arizona Emergency Medicine Research Center and the American Academy of Clinical Toxicology.

Our faculty members, Dr. Frank Walter, Dr. Farshad “Mazda” Shirazi, Dr. Robert French, Dr. Peter Chase, and Dr. Steven Dudley actively participate in a variety of research projects and have particular expertise in hazardous material, and occupational exposures, emergency management, envenomations, geriatrics, drug-drug interactions, and withdrawal.
