About Risperdal

  • Risperdal is in a class of medications called atypical antipsychotics. Antipsychotic medicines are used to treat symptoms of schizophrenia that may include hearing voices, seeing things, or sensing things that are not there, mistaken beliefs or unusual suspiciousness.
  • Risperdal may be used alone or with lithium or divalproex for short-term treatment of mixed or manic episodes in adults who have a condition called Bipolar I disorder. Bipolar disorder is a mental illness that causes extreme mood swings.

Precautions for Risperdal

  • Dizziness, and sometimes fainting, caused by a drop in blood pressure may happen with Risperdal, especially when you first start taking this medicine or when the dose is increased.
  • Risperdal may impair judgment, thinking, or motor skills. You should be careful in operating machinery, including automobiles, until you know how Risperdal affects you.
  • It is important to avoid overheating and dehydration while taking Risperdal. Risperdal may make it harder to lower your body temperature.

Side Effects of Risperdal

The following are the risks and potential side effects of Risperdal therapy. However, this list is not complete.

  • Increased chance of death in elderly persons. Elderly patients treated with atypical antipsychotics, such as Risperdal, for dementia had a higher chance for death than patients who did not take the medicine. Risperdal is not approved for dementia.
  • A life-threatening nervous system problem called neuroleptic malignant syndrome (NMS). NMS can cause a high fever, stiff muscles, sweating, a fast or irregular heart beat, change in blood pressure, and confusion. NMS can affect your kidneys. NMS is a medical emergency. Call your healthcare professional right away if you experience these symptoms.
  • A movement problem called tardive dyskinesia (TD). Call your healthcare professional right away if you get muscle movements that cannot be stopped.
  • High blood sugar and diabetes. Patients with diabetes or who have a higher chance for diabetes should have their blood sugar checked often.

Has anyone ever heard of a child taking 1 mg. of rispideral for adhd?

autistic son on Risperdal

My 14 year old son who has moderate autism has been on Risperdal for
7 years now. Dr. Bennett Leventhal from U of Chicago prescribed it.
His speech greatly improved and doctor and I both agree that the drug
slowed his brain down so that he was able to learn more and focus in
to what we were trying so hard to teach him. I have nothing but praise
for the drug and believe it is key to where we are now with regards
to his independence and his interest in learning new things and
wanting to work hard at his jobs that he does at home and out in the
community. The drug never made him a zombie like I have heard alot
of parents being fearful of their children becoming on these anti
pyschotic drugs. So give it a chance. If it's not the right drug for
your child you will know pretty much tight away and it will always be
your choice as the parent to take him off the drug.

beware of galactorhea (lactation) or gynecomastia (breast enlargement) two unpleasant side effects; we tried Seroquel with good results.

son with Asperger's Syndrome on Risperdal

My son was diagnosed with Asperger's Syndrome when he was 8-years old. When he was 10, his mood swings became physically violent. His psychiatrist prescribed Risperdal. It helped moderate the mood swings, but he gained a lot of weight. He is now 12-years old and is 5-9 and 200 pounds. He stopped taking Risperdal, at his request, about 4 monthes ago because he was getting teased about his size. Maybe because his is older, but he is able to manage his mood better on his own and is not as aggressive as he was when he was younger. I would say to anyone considering Risperdal for their child, just watch the side effects. I don't know what we would have done without it.
