A former Mt. Pleasant oral surgeon was sentenced to two years in federal prison this week for fentanyl tampering. The individual, 55-year-old Dr. Andrew Charles Hartwig, had a dental practice in Iowa City as well. 

Last October, Hartwig admitted to tampering with vials of fentanyl from his former practice, Oral Surgery Associates of Iowa City. Using the medication for his own personal use, Hartwig would conceal his actions by diluting the fentanyl with saline. This went on from as early as April 2019 until at least July 10, 2019. Hartwig’s license was suspended indefinitely after an investigation later that year. 

Following his prison sentence, Hartwig will have two years of supervised release. He was also ordered to pay a fine of $50,000. The case was investigated by the Food and Drug Administration, Office of Criminal Investigations, and Drug Enforcement Administration.
