What Is Risperidone?


Risperidone is an atypical antispsychotic drug -- originally developed by Janssen-Cilag and released in 1994 -- that is sold under the brand name Risperdal®.

Generally, the drug is utilized in treating schizophrenia, schizoaffective disorder, bipolar disorder and is also used to treat irritability in people with autism. Although Risperidone is known as an efficient treatment for mood disorders in those with autism it is also accepted that it does not improve social skills or conversational ability.

It has been linked with causing serious weight gain, metabolic problems, tardive dyskinesia and neuroleptic malignant syndrome.

Originally approved for schizophrenia

The Food and Drug Administration (FDA) approved risperidone in 1993 for the specific treatment of schizophrenia. Later, in 2003, the FDA approved risperidone for short-term treatment of the manic states associated with bipolar disorder. In 2006, the FDA approved risperidone for the treatment of irritability in children who have autism. August of 2007 marked the point when risperidone was cited as the only drug agent available that could treat schizophrenia in children and teenagers ages 10-17.

Risperidone contains groups of benzisoxazole and piperidine as part of its molecular structure.

This drug, like any other, may react poorly with a person’s body in certain situations. Stop using risperidone and call your doctor at once if you have any of these serious side effects:

  • fever, stiff muscles, confusion, sweating, fast or uneven heartbeats;
  • restless muscle movements in your eyes, tongue, jaw, or neck;
  • tremor (uncontrolled shaking);
  • fever, chills, body aches, flu symptoms;

Anyone who is considering taking the drug, should consult with their personal physician beforehand.
