On Wednesday, U.S. Representative Dan Kildee (D-Flint) requested from several members of Congress to use their oversight authority to investigate a pharmaceutical company that created a price surge for lead poisoning treatment drugs.

The pharmaceutical company, Valeant, increased the price of their drug Calcium Disodium EDTA from $900 to $27,000 per treatment, a 3,000 percent surge. This drug is deemed needed and almost necessary as Flint, Representative Kildee’s hometown, works towards removing lead from the water and combating lead poisoning. In the letter, Mr. Kildee added the World Health Organization has included Calcium Disodium EDTA on its list of Essential Medicines because it is used to save children’s lives. In his opinion, the increase in price is unconstitutional.

The letter was sent to the U.S. House Committee on Oversight and Government Reform chair, U.S. Representative Jason Chaffetz (R-Utah) and U.S. Committee on Energy and Commerce chair U.S. Representative Fred Upton (R-St. Joseph). The letter was also issued to the ranking members of each of those committees, U.S. Representative Elijah Cummings (D-Maryland) and U.S. Representative Frank Pallone (D-New Jersey), respectively.
