Risperidone and restless legs: what to know

Restless legs often feels like an urge to move, crawling, pulling or tingling deep in the legs, commonly becoming worse while resting or later in the day. A medication-related movement problem can instead feel like an inability to sit still, pacing, shifting position or general agitation. The two can overlap, and the timing matters: symptoms that began after starting risperidone or after a dose change deserve a medication review. Other contributors include iron deficiency, kidney disease and nerve problems. Read about [Restless Legs Syndrome](/conditions/restless-legs-syndrome/) and [Peripheral Neuropathy](/conditions/peripheral-neuropathy/) for background.

Record when the sensation starts, whether movement relieves it, how sleep is affected and any recent risperidone dose changes. Contact the prescribing clinician or a GP for a review; they may assess the pattern, examine movement and consider blood tests such as iron studies when appropriate. Do not stop risperidone suddenly or alter the dose without advice. If iron deficiency is found, treatment may include [Iron Supplementation](/treatments/medical-management/iron-supplementation/), but supplements should be guided by test results.

Seek urgent medical help for severe agitation, uncontrolled movements, confusion, fainting, a high fever with marked stiffness, or thoughts of harming yourself or someone else. Arrange prompt clinical advice if symptoms are rapidly worsening, prevent sleep repeatedly, or are accompanied by weakness, numbness or difficulty walking. A clinician can distinguish a medication effect from [Restless Legs](/symptoms/restless-legs/) or another condition.

Could this be medication-related restlessness rather than restless legs? Should the dose or timing be reviewed? Do I need iron or kidney tests? Which symptoms would mean I should seek urgent help?
