Tardive dystonia occurs after exposure to dopaminergic blocking agents, usually after long-term exposure, and may not improve despite discontinuation of the offending agent. Dopamine-blocking agents associated with tardive dystonia are most frequently antipsychotic medications but also include antiemetics, such as metoclopramide. The effects of tardive dystonia are often disabling and compromise quality of life due to abnormal movements and the pain produced by these.
