Educational Opportunities

The Wisconsin Poison Center offers clinical experiences to rotating students and residents from a variety of backgrounds and levels of training every year, starting in late August and running until late June. The month-long rotation consists of direct participation in the clinical consultation services of patients managed with the help of the WPC as well as daily didactic lectures by MCW Toxicology faculty members. The WPC is a required rotation for 2nd year MCW Emergency Medicine residents and is available to physician and pharmacist residents as well as fellows and MCW/Children's Wisconsin as well as those from other institutions as space permits. The Medical Toxicology elective is also offered to up to two MCW medical students per month, and to NP/PA students and residents pending available space.
