Which of the following is a common approach to treating akathisia?

• A. Antihistamines
• B. Stop the offending medication
• C. Possibly beta blockers
• D. Antidepressants

Answer: (A)

Akathisia happens when dopamine blockade in the nigrostriatal pathway creates signs of inner restlessness and an urge to move, a result of relative cholinergic overactivity. A practical way to relieve these symptoms is to counter that imbalance with an agent that has anticholinergic effects. Antihistamines with anticholinergic properties, such as diphenhydramine, can blunt the striatal cholinergic activity and lessen the urge to move, making them a commonly used symptomatic option. They are convenient and generally well tolerated, which is why they’re often chosen when a quick, accessible intervention is needed or when other options aren’t suitable. Of course, stopping or lowering the offending antipsychotic remains a fundamental step to address the root cause and may be necessary for long-term control. Beta-blockers like propranolol can also help with akathisia by reducing peripheral sympathetic symptoms and agitation, and benzodiazepines can be used for anxiety, but the question points to antihistamines as a widely used approach for symptom relief when addressing these extrapyramidal effects. Antidepressants do not directly treat akathisia.
