An Acute Dystonia Case Induced by Addition of Quetiapine With a Single Dose on Fluoxetine and Trazodone

Abstract

A patient admitted with complaints of muscle contractions in neck, shoulder and arm which started recently after quetiapine administration. As a result the patient developed dystonia after adding a single dose of 12.5 mg/day quetiapine while taking trazodone and fluoxetine treatment. In this paper we take a look at the literature concerning quetiapine and dystonia. In this context it is warranted to be aware of combination therapy's side effects, including ones that are considered having a lower risk of extrapyramidal symptoms such as quetiapine.
