  Risperidone may cause a condition called orthostatic hypotension during the early phase of treatment (the first week or two). [medicinenet.com]

• Motor Restlessness

  These include dyskinesias such as repetitive, involuntary, and purposeless body or facial movements, Parkinsonism (cogwheel muscle rigidity, pill-rolling tremor and reduced or slowed movements), akathisia (motor restlessness, especially in the legs, and [library.neura.edu.au]

  These disorders include akathisia (motor restlessness), dystonia (abnormal muscle tone), and tardive dyskinesia (involuntary and repetitive movements). [ncbi.nlm.nih.gov]

• Prolonged QT Interval

  BACKGROUND: Numerous structurally unrelated drugs, including antipsychotics, can prolong QT interval and trigger the acquired long QT syndrome (aLQTS). All of them are thought to act at the level of KCNH2, a subunit of the potassium channel. [ncbi.nlm.nih.gov]

  Hyponatremia, hypokalemia, prolonged QT interval, widened QRS complex, and seizures also have been reported. There’s no specific antidote to risperidone overdose; institute appropriate supportive measures. [glowm.com]

RESULTS: PANSS scores before treatment were comparable between treatment groups. On days 7, 15, 30, and 60 of the treatment, the differences between two treatment groups became evident. [ncbi.nlm.nih.gov]
