Minoxidil, a topical treatment for alopecia, can cause severe health issues if ingested, including refractory circulatory shock and acute pulmonary edema. A case study of a young female who unintentionally ingested minoxidil highlights the need for immediate treatment with aggressive hydration and vasopressors. Midodrine may help reduce ICU stay by decreasing the duration of IV vasopressor use.
