How do you manage acute dystonia?

How do you treat a dystonic reaction?
Acute dystonic reactions are a common and distressing complication of antiemetic and antipsychotic drugs. Treatment with intravenous benztropine is safe and produces rapid relief. Patients who have a possible acute dystonic reaction should initially be treated with benztropine.
Is dystonic reaction an emergency?
In rare instances, as with laryngeal involvement, airway management may be necessary. Dystonic reactions are typically not life threatening and result in no long-term effects.
What medications cause acute dystonic reaction?
Neuroleptics (antipsychotics), antiemetics, and antidepressants are the most common causes of drug-induced dystonic reactions. Acute dystonic reactions have been described with every antipsychotic.
How long does acute dystonia last?
Acute dystonic reactions usually occur within a few hours of taking a causative medication, but onset may be delayed a few days. Untreated the condition gradually resolves over a few days. It is rarely life-threatening (e.g. laryngeal dystonia).
Is acute dystonia permanent?
There’s no cure for dystonia. But medications can improve symptoms. Surgery is sometimes used to disable or regulate nerves or certain brain regions in people with severe dystonia.
Does acute dystonia go away?
Treatment for acute dystonia includes discontinuing the offending drug and treatment with anticholinergics or antihistamines (i.e. diphenhydramine), often injected or intravenously. Even without medical treatment, most cases resolve within 12 to 48 hours.
Does Benadryl help with dystonia?
Main Outcome Measure: Dystonia evaluation. Results: Diphenhydramine therapy was associated with minimal side effects, and it was most effective in treating patients with dystonia who experienced lightning jerks.
Does Zofran cause dystonia?
Conclusions: Dystonia and seizures have been associated with ondansetron in a few case reports. In addition, clinicians need to consider hypoglycemia as a possible adverse effect of ondansetron.
How do you administer benztropine IV?
The recommended dose is 1 to 4 mg IV, IM, or PO once or twice daily. Acute dystonic reactions generally respond to 1 or 2 mg IV or IM, followed by an oral dose to prevent recurrence. Reevaluate the need for benztropine after several days of treatment.
How serious is dystonia?
The condition can affect one part of your body (focal dystonia), two or more adjacent parts (segmental dystonia) or all parts of your body (general dystonia). The muscle spasms can range from mild to severe. They may be painful, and they can interfere with your performance of day-to-day tasks.

The options include:
- Carbidopa-levodopa (Duopa, Rytary, others). This medication can increase levels of the neurotransmitter dopamine.
- Trihexyphenidyl and benztropine (Cogentin).
- Tetrabenazine (Xenazine) and deutetrabenazine (Austedo).
- Diazepam (Valium), clonazepam (Klonopin) and baclofen (Lioresal, Gablofen).
What drugs cause dystonic reaction?
dystonic reaction is a common side effect of antipsychotics, but can be caused by any agents that block dopamine receptors, such as the antidepressant amoxapine and anti-emetic drugs such as metoclopramide.
What medications cause dystonic reaction?
“Some drugs in the neuroleptic category (psychiatric drugs) may cause acute dystonic reactions: thorazine, Haldol, etc. Ten to twenty percent of patients experience acute dystonic symptoms at the initiation on treatment.
What causes medication-induced dystonic reactions?
They reportedly arise from a drug-induced alteration of dopaminergic-cholinergic balance in the nigrostriatum (ie, basal ganglia). Most drugs produce dystonic reactions by nigrostriatal dopamine D2 receptor blockade, which leads to an excess of striatal cholinergic output.
