The Infectious Diseases Society of America has also objected to this massive price increase, sending a letter urging Mr. Shkreli's company to "help us improve public health by immediately implementing a rational and fair pricing strategy." The group also warned that toxoplasmosis, the parasitic infection Daraprim treats, would have "severe consequences if not effectively treated in pregnant women, patients with HIV infection, cancers and other conditions that compromise the immune system."
Rather than heeding this request from a group of more than 10,000 infectious disease physicians and scientists, Mr. Shkreli mocked their concerns. When asked how he could sleep at night, Mr. Shkreli tweeted, "you know, ambien."
