Sir,
Pombo et al.[1] reported a 26-year-old male who stopped taking mirtazapine 4 days before death, resulting from violence associated with sudden-onset abnormal behavior. The authors concluded that the abnormal behavior was mania induced by mirtazapine withdrawal, as confirmed at autopsy by very low levels of mirtazapine and its metabolite in blood.
We are deeply concerned by these conclusions. First, there is not a shred of evidence presented by the authors that supports the diagnosis of mania. Given the history of schizophreniform disorder and cannabis abuse, the patient may well have had a nonaffective psychotic relapse that may or may not have been related to cannabis. Next, early cognitive-behavioral changes associated with relapse into psychosis may have been responsible for mirtazapine discontinuation, rather than mirtazapine discontinuation having been responsible for psychosis onset. A mere temporal succession of events does not establish a cause–effect relationship. In this context, would discontinuation of cannabis and finding low levels of cannabis in the blood establish cannabis as a cause of the psychosis?
Finally, we are particularly concerned by the sensationalism in the title and the hyperbole in the concluding sentence of the discussion. Flawed interpretation of events and exaggerated recommendations can be amplified by the media and can harm patient sentiments. The measles, mumps, and rubella vaccine story is an excellent example of how much public health damage a single irresponsible paper can cause.[2]
