Walking a Tightrope Between Relief and Relapse
Treating akathisia is rarely as simple as stopping a pill. Often, the drugs that trigger the condition are the same ones holding serious mental illness at bay. The challenge is to quiet the torment without losing control of the underlying disorder.
First Move: Change the Offending Drug
When akathisia appears after starting or increasing an antipsychotic, the primary strategy is straightforward in theory:
- Reduce the dose of the offending medication
- Switch to an antipsychotic with a lower risk of causing akathisia
In many cases, symptoms improve quickly once the brain is no longer being pushed so hard by the problematic drug.
Medications That Can Help
Several types of medicines can ease the restlessness of acute, drug-induced akathisia:
- Low-dose mirtazapine, an antidepressant that, paradoxically, has also been associated with triggering akathisia in some individuals
- Beta blockers, especially propranolol, which dampen the body’s adrenaline-like responses
- Benzodiazepines such as lorazepam, which enhance the brain’s main calming system
- Anticholinergics like biperiden and benztropine, commonly used for other extrapyramidal side effects
- Serotonin antagonists such as cyproheptadine
Vitamin B supplementation and iron replacement, when deficiencies are present, may also provide some benefit.
The Chronic Challenge
These treatments tend to work best for acute akathisia, appearing soon after a medication is started or increased. Chronic or tardive akathisia – symptoms that persist for months or years after the drug is stopped – is far harder to treat and often responds poorly to the same tools.
When the Cure Can Cause the Disease
Ironically, some of the very drugs used to treat akathisia can also cause it. Benzodiazepines and antidepressants sit uncomfortably on both sides of the equation, sometimes soothing restlessness, sometimes provoking it, especially around changes in dose or withdrawal.
The Takeaway
Managing akathisia is an exercise in precision and humility. It demands careful adjustment of powerful medications, creative use of supporting drugs, and constant attention to the patient’s subjective experience. Done well, it can transform a state of unbearable restlessness into something livable again—without sacrificing the benefits of essential psychiatric treatment.
