A Tustin psychiatrist with a long history of discipline by the Medical Board of California was recently slapped with a cease practice order.

Dr. David Sosin’s license to practice medicine in the state had been placed on five years probation with several conditions, one of which was that he have his practice monitored by a board-approved physician or surgeon.

Sosin’s monitor became unavailable, which kicked in a 60-day deadline for him to find a replacement. That didn’t happen, so as of 5 p.m. on Feb. 15, Sosin’s cease practice order went into effect, according to medical board documents.

He first received his California Physician’s and Surgeon’s Certificate in 1967, and his troubles with the medical board extend at least as far back to 1998, when he was investigated for excessive prescribing of Ritalin and Dexedrine to a female patient from 1984-’96.

The board revoked Sosin’s license to practice in 1999, but stayed the order for three years as long as he successfully completed a number of conditions. His license was restored in 2002, according to state records.

Linda K. Whitney, the medical board’s then-executive director, sent Sosin a Letter of Reprimand dated Feb. 24, 2012, that cited prescribing doses of stimulants to patients that exceeded Food and Drug Administration recommendations as well as failing to adequately monitor and provide informed consent on combined stimulants.

In 2016, Sosin’s license was placed on probation for five years due to “gross negligence” for: failing to stop treating a patient after learning he secretly put his prescribed Lexapro in his wife’s food; overprescribing Vyvanse and other drugs to other patients without proper examinations; prescribing multiple stimulants and medications simultaneously; and failing to send patients to other professionals for non-psychiatric conditions, and treating them for those conditions when they were beyond his scope.

Sosin was also accused of incompetence, repeated negligent acts, inadequate record keeping, general unprofessional conduct and, because he allowed a lay person to put Lexapro in a spouse’s food, aiding and abetting the unlicensed practice of medicine.

A new medical board accusation was lodged against Sosin’s license in 2018, when he allegedly prescribed a cocktail of stimulants and other medications to a patient he diagnosed with ADHD. She went on to tell Sosin she was also using marijuana and experiencing adverse effects of the prescription medications. She eventually complained to the medical board, whose investigators determined he should have ended his doctor-patient relationship with her.

Causes for discipline cited by the board included incompetence, gross negligence, excessive prescribing, repeated negligent acts, general unprofessional conduct, inadequate record keeping and prescribing without exam/indication.

Board documents indicate Sosin’s past discipline would be considered.
