A man claiming the antidepressant Zoloft caused him to beat up his ex-girlfriend may tap an expert witness to back up his defense, a New York state judge has ruled. But the judge also held that an expert witness for Pfizer, the maker of Zoloft, may take the stand in rebuttal. At a pretrial hearing in January, the defense expert testified that some users of antidepressants like Zoloft may suffer "significant side effects which may include impulsivity, agitation, excessive aggression, grandiosity and hypomania."
