A Winchester physician on Thursday entered into an agreed order with the state medical board to surrender his license.
In May, the board suspended Quentin F. Murray's license in an emergency order. Board documents allege that Murray inappropriately prescribed several medications, including the painkiller Oxycodone, to a woman with whom he was having a sexual affair. The order also said that Murray was not "legally entitled" to prescribe methadone to a 32-year-old man who then died in 2010 after suffering cardiac arrest.
At that time, Murray's attorney said he denied the allegations.
A coroner did not find that the cause of death was related to the methadone in the man's system, but a board consultant said in the order that methadone should not be given to a person with morbid obesity. The man was morbidly obese.
Board documents said Murray told board officials that he had an affair with a woman he had worked with at a facility and he wrote prescriptions for her even though he knew it was wrong. Murray said he did not keep a patient record for her.
Under the order signed Thursday, Murray cannot apply for reinstatement of his license for two years.
