A Review of Dr. Breggin’s Medical Expert Experiences

Dr. Peter Breggin often acts as a psychiatric and medical expert or as a consultant in criminal, malpractice, product liability and class action suits. This page presents a list of over 70 of his more interesting and successful trials and settlements.

In greatly updating this legal page in early December 2017, Dr. Breggin was able to retrieve information about most of his trial successes since 1986, but not before that time.  Unfortunately, information about many dozens of cases successfully settled before going to trial has not been easy to locate, and only a few are listed. Many of Dr. Breggin’s most interesting cases are described in detail in his book, Medication Madness: the Role of Psychiatric Drugs in Cases of Violence, Suicide and Crime.

Based on his experience over 50 years, bolstered by his many scientific books and articles, Dr. Breggin is among the most experienced psychiatric experts in the world. He also maintains a private practice in Ithaca, New York.

Dr. Breggin has been a consultant or testified in many high profile cases, such as the Columbine High School and Aurora Theater mass murders and the recent Michelle Carter case—the girl who alleged “texted her boyfriend to death.” He has also been a consultant to the Federal Aviation Agency (FAA) on adverse drug effects on pilots.

Based in part on his expertise adverse drug effects, he has not only been qualified innumerable times to testify in malpractice cases against psychiatrists, but also against doctors in many other specialties such as general practice, pediatrics, internal medicine, neurology and neurosurgery, as well as non-physician healthcare providers.

Dr. Breggin’s testimony has involved every class of psychiatric drug, including antidepressants, benzodiazepine tranquilizers, sleeping aids, antipsychotic drugs, stimulants for children diagnosed ADHD. Many cases involve polydrug administration, often involving non-psychiatric drugs as well.

He has testified or consulted on many other cases involving non-psychiatric drugs that have caused brain damage, death and other injuries including psychiatric or neurological crises caused by the following: antibiotics such as Bactrim and Accutane; antiviral agents; cardiovascular medications; Tegretol, opioids and other drugs used to treat pain; and neuroleptics used for non-psychiatric purposes such as Compazine and Phenergan for nausea and vertigo. He has testified or consulted about medication-induced diabetes, cardiovascular problems, fetal developmental abnormalities, and infant and child exposure to Reglan (metoclopramide).

Cases often include drug-induced tardive dyskinesia, neuroleptic malignant syndrome (NMS), serotonin syndrome, suicide, violence, and death from drugs.

He has testified concerning standards for prescribing in private practice, clinics, hospitals, nursing homes, and the Veterans Administration (VA).

He has testified on behalf of parents when mental facilities, state agencies and courts have tried to force them to give psychiatric drugs to their children or elderly parents.

Dr. Breggin has testified in cases involving electroshock (ECT) and psychosurgery, and was the expert in the first ECT and first psychosurgery malpractice cases won in trial



The following list of Dr. Peter Breggin’s experiences in legal cases does not include the very large number of those that have settled on the condition of secrecy. For example, one of his malpractice cases in which he was the sole medical expert resulted in the largest settlement of its kind ever, but required him to remain silent about it.

 2002: Massive Lacuzong Paxil product liability suit settled in January against GlaxoSmithKline (GSK). Lacuzong drowned himself and his two small children in a bathtub immediately after starting Paxil and developing akathisia (a dangerous psychomotor agitation).  The heart of the successful case was Dr. Breggin’s lengthy expert opinion and report based on his three-day onsite investigation of GSK’s secret files.  Unfortunately, the settlement sealed Dr. Breggin’s large Lacuzong report.  Then in 2006, in another Paxil/GSK productive liability suit involving Dr. Breggin, a new judge opened Dr. Breggin’s report to the public.   In quick succession, Dr. Breggin published three detailed scientific reports on Paxil-induced violence, suicide and akathisia, as well as the negligence and fraud perpetrated by GSK in developing and marketing  Paxil.
