The 19-year-old had felt weak for several days. Then she took a single ibuprofen tablet and, within a short time, was struggling to breathe, vomiting repeatedly, and slipping into lethargy. Paramedics brought her to an emergency department in Rafsanjan, Iran, where staff initially suspected acute pulmonary edema.
Her oxygen saturation was 75%. Her heart was racing at 145 beats per minute. Her Glasgow Coma Scale score was 13, indicating impaired consciousness.
