Medication-Induced Acute Akathisia
A movement-related side effect involving a subjective feeling of inner restlessness and a compelling need to be in constant motion, associated with certain medications.
Overview
Medication-induced acute akathisia involves subjective complaints of restlessness, often accompanied by observed excessive movement such as fidgeting or pacing, developing within days to weeks of starting or increasing certain medications, most commonly antipsychotics.
Signs and Symptoms
Symptoms can include an intense, uncomfortable urge to move, inability to sit still, pacing, and significant distress, which can sometimes be mistaken for anxiety or agitation. Experiencing one or more of these symptoms does not necessarily mean that a person has this condition. Diagnosis requires an appropriate clinical evaluation.
Causes and Risk Factors
Akathisia is most commonly caused by antipsychotic medications, though it can occur with other dopamine-affecting medications as well.
Diagnosis
A diagnosis should be made by a qualified healthcare professional following a comprehensive clinical assessment. Clinicians may use established diagnostic frameworks such as DSM-5-TR and/or ICD-11 as part of a comprehensive assessment.
Treatment
Treatment depends on the individual’s symptoms, clinical history, severity, age, co-occurring conditions, and other relevant factors.
Psychotherapy
Recognizing akathisia as a medication side effect, rather than a worsening of the underlying condition, is an important part of appropriate management.
Medication
Adjusting the dose or type of causative medication, or adding a medication to treat akathisia symptoms, is generally effective under medical guidance. Medication decisions should be made with a qualified prescribing healthcare professional. Do not start, stop, or change a prescribed medication based solely on information on this page.
Living With Medication-Induced Acute Akathisia
Report new restlessness or an inability to sit still after starting a new medication to your prescribing provider promptly.
When to Seek Professional Help
Professional evaluation may be appropriate if symptoms persist, worsen, cause significant distress, or interfere with work, school, or relationships.
Emergency Situations
If a person may be in immediate danger, is experiencing a medical or psychiatric emergency, or may harm themselves or another person, seek immediate assistance through appropriate local emergency services.
Outlook
Akathisia typically improves significantly with appropriate medication adjustment.
