Is drug induced dystonia permanent?

The potential cause of drug induced dystonia is the development of dopamine receptor hypersensitivity after prolonged blockade of these receptors with the use of antipsychotics or anti emetics. In almost all instances, drug induced dystonias are reversible, resolving after the discontinuation of the offending drug.
