Sir: Akathisia may be defined as the subjective feeling of muscle discomfort usually manifesting as a result of treatment with antipsychotic medication. Moreover, the subjective experience is often associated with objective symptomatology such as restless leg movements, walking to and fro, and inability to sit in one place for an extended period of time. This undesirable side effect frequently expresses itself as a formidable therapeutic challenge. While akathisia is most commonly expressed following the use of antipsychotic medication, often it may be observed resulting from the use of antidepressant therapy, in particular drugs of the selective serotonin reuptake inhibitor (SSRI) class expressing serotonin-2A (5-HT2A) stimulatory effects. Various reports have estimated the occurrence rate of this phenomenon of SSRI-induced akathisia to range from 9.8% to 45.1%.
