Guide To The Causes Of Cervical Dystonia

Certain Medications

Certain medications have been known to cause cervical dystonia and other types of dystonia as a side effect. This is most commonly reported with medications that block the brain's release of dopamine, which is required for the smooth and controlled movement of muscles. If individuals don't have enough dopamine, their muscles may spasm or become tense and rigid. When this is the case, they might develop cervical dystonia alongside other muscle problems. Many antipsychotics block dopamine in the brain, since psychotic symptoms have been linked to increased dopamine levels. Some medications that block dopamine and may cause dystonia include clozapine, quetiapine, risperidone, paliperidone, promethazine, metoclopramide, and chlorpromazine. If individuals are experiencing painful muscle symptoms as a side effect of their medication, they should talk to their doctor about lowering their dose or switching to a different type of medication. Sometimes changing medications or adjusting the dosage will be enough to stop the symptoms from continuing.
