A Chicago doctor was charged after allegedly giving IV treatments from a home in northern Indiana without a license to practice medicine in the state, according to WNDU, the NBC affiliate in South Bend.
Michael Close, 62, was charged with two counts of practicing medicine without a license and unlawful possession or use of a legend drug. He also faces a battery charge.
Citing court documents, WNDU reported investigators received a letter raising concerns about a woman’s welfare, claiming Close was injecting her with IV NAD treatments at a Warsaw, Indiana, home. Under state regulations, such treatments typically require physician oversight.
Police said a detective went to the residence, where syringes and vials were discovered inside Close’s car. He admitted injecting the woman to police, but said he administered the vitamin B-12. He also admitted his medical license had been suspended.
According to his website, Close bills himself as a neurologic specialist who “delivers advanced restorative medicine through personalized NAD+ therapies” and lists an office at 4906 N. Western Ave. in the Lincoln Square neighborhood.
However, his license in Illinois remains suspended, according to the Illinois Department of Financial and Professional Regulation. Most recently, Close was suspended March 3, 2026, for a minimum of 12 months, with the department citing a violation of a 2021 consent order.
Records showed Close’s license was suspended in 2013 for failure to account for over 21,000 dosage units of controlled substances.
