drug-induced dystonic reactions

Last reviewed 01/2018

Examples of causes acute dystonia include dopamine receptor antagonists such as:

  • phenothiazines
  • prochloperazine
  • haloperidol
  • metclopramide

The newer atypical antipsychotic drugs (e.g. risperidone, onlanzapine) are more selective for dopamine D2 receptors and therefore are less likel to cause these adverse effects.
