Does Ativan Help with Akathisia Due to Risperdal?
Yes, lorazepam (Ativan) can help manage akathisia caused by risperidone (Risperdal), though it is not the first-line treatment. The most recent APA guidelines recommend considering benzodiazepines as one of several options for antipsychotic-induced akathisia 1.
Treatment Algorithm for Risperidone-Induced Akathisia
First-Line Approaches
The optimal initial strategy is to lower the risperidone dose or switch to another antipsychotic with lower akathisia risk (such as quetiapine or olanzapine) 2, 1. The 2020 APA guidelines specifically suggest three options for akathisia: lowering the antipsychotic dose, switching to another agent, or adding adjunctive medication 1.
When to Use Lorazepam
If dose reduction or switching is not clinically feasible (e.g., psychotic symptoms are well-controlled and you cannot risk destabilization), lorazepam becomes a reasonable adjunctive option 1. The APA guidelines list benzodiazepines alongside beta-blockers as acceptable add-on treatments for akathisia 1.
Evidence Supporting Lorazepam for Akathisia
The evidence base is modest but supportive:
A 1987 open trial showed marked improvement in 9 of 16 patients with neuroleptic-induced akathisia treated with lorazepam, with statistically significant reductions in akathisia scores from 1.81 at baseline to 0.32 after 14 days 3.
One case report documented successful management of olanzapine-induced akathisia when the drug was reintroduced in combination with lorazepam after initial akathisia resolution 4.
A 2021 case report noted that lorazepam was attempted (though ultimately unsuccessful) for lithium-induced akathisia in a patient also on risperidone 5, suggesting it is commonly used in clinical practice.
Practical Dosing Considerations
While specific dosing for akathisia is not well-established in guidelines, typical starting doses would be lorazepam 0.5-2 mg as needed, based on its use in agitation management 6. The FDA label for risperidone confirms that akathisia occurs in 8-10% of adult patients on risperidone 7.
Alternative and Preferred Options
Beta-blockers (particularly propranolol 10-30 mg two to three times daily) have stronger evidence as first-line pharmacologic treatment for akathisia 2, 1. A 2021 review using the mnemonic "B-CALM" (Beta-blockers, Clonazepam, Anticholinergics, cLonidine, Mirtazapine) noted that current evidence best supports propranolol and mirtazapine 8.
Important Caveats
Anticholinergic agents are generally NOT helpful for akathisia (unlike other extrapyramidal symptoms like dystonia or parkinsonism) 9, 1.
Benzodiazepines carry risks of tolerance, dependence, cognitive impairment, and paradoxical agitation (occurring in ~10% of patients) 10, so they should be used judiciously and for the shortest duration necessary.
Akathisia is frequently misdiagnosed as psychotic agitation or anxiety 9, which can lead to inappropriate dose escalation of the offending antipsychotic—worsening the problem. Careful assessment is critical.
Bottom Line
Lorazepam can provide symptomatic relief for risperidone-induced akathisia when dose reduction or switching is not possible, but beta-blockers like propranolol should be considered first-line pharmacologic treatment. The combination approach of continuing risperidone with adjunctive lorazepam has documented success 4, making it a viable strategy when maintaining antipsychotic efficacy is paramount.
