Reckless Benzo Prescribing

Without exaggeration, Dr. Marvin Witt very nearly cost me my life and they have certainly destroyed my health in a profound way. To begin with, one of ACP’s cardiologists prescribed me a psychotropic drug called clonazepam, for a tight chest. Cardiologists have no place prescribing these medications. Furthermore, he prescribed a very large quantity, notwithstanding that the New York State Department of Health Guidelines clearly state, in a broadly cited pamphlet distribution that clonazepam should never be prescribed beyond 2 - 4 weeks. After a short term of taking clonazepam I found I was unable to sleep (at all) without it. I visited Dr. Marvin Witt about this and he immediately, without hesitation reinstated clonazepam and continued to do so for 7.5 years completely unmonitored. During this time I developed profound periods of depression, anxiety, insomnia and boils and rashes for the first time in my life. I developed cataracts in both eyes at the age of 52 (it’s documented that clonazepam causes these conditions if prescribed long term). Each time I returned to the Dr. Witt he failed to connect my condition to his prescribing of clonazepam and instead prescribed a myriad of additional pharmaceuticals. Eventually I developed complete tolerance to the clonazepam meaning that I had night sweats, night terrors and excruciating insomnia. At this point Dr. Witt wrote to me by email on ACP’s portal instructing me to discontinue clonazepam “cold turkey” (this was the precise term he used). Two days later I was unable to walk or talk and I was having myoclonic seizures and my friends took me to the ER whereupon they reinstated me with clonazepam telling me that abrupt discontinuation was life threatening. I returned to ACP and saw a different physician (Dr. Thomas Moore) who explained that I needed to discontinue clonazepam but that ACP did not have the expertise to oversee a taper. He told me I needed to seek assistance from an addiction specialist although he did not refer me to one. In other words they admitted they had gotten me dependent on a drug from which they had no idea how to get me off. I had to find an addiction psychiatrist at the cost of thousands (none of these take Insurance). I had to taper slowly with the help of a compounding pharmacist which also cost me thousands. In the period of my self-styled taper I had nine months of sleeping between zero and two hours out of every 24. I had hallucinations, nighttime and daytime terrors, and worst of all akasthesia which meant I was compelled to march on the spot pretty much every waking moment. And guess how many times ACP physicians reached out to enquire for my welfare? The answer is none. To anyone reading this, I promise and guarantee there is zero exaggeration in the above commentary. If anyone requires further information I will happily provide with documentary evidence. I am now physically disabled from Dr. Witt’s medical treatment. I have been free of clonazepam and any related meds for 18 months and although my mind is liberated with zero depression or anxiety, my central nervous system is severely compromised. My muscles are profoundly stiff 24/7 as clonazepam is a muscle relaxant and without it the muscles can no longer function efficiently. I cannot descend subway stairs without assistance and I was an elite athlete before Dr. Witt got me. I believe with every ounce of my being that these physicians’ white coats should be replaced with orange jump suits. But I would encourage anyone reading this, be they current patients or prospective, to consider the dangers this certain members of the ACP medical group may present to them, in light of my experiences. I have written to ACP explain this situation and requesting explanations but so far they have not even acknowledged my complaint. I fear that they may regard safety under the veil of silence.
