Risperdal and Invega Lawsuits filed

Lawsuits have been filed n behalf of boys and young men who developed serious side effects - including the growth of breasts - while taking the antipsychotic medications Risperdal and Invega.

The drugs are made by Janssen, a division of Ortho-McNeil-Janssen Pharmaceuticals Inc., which is part of Johnson & Johnson.

Risperdal and Invega are antipsychotic drugs with similar chemical structures and side effects, Sheller said. In children and adolescents, Risperdal is FDA-approved for treatment of schizophrenia, bipolar mania, and symptoms of autism.


Important information about Risperdal

Risperdal is not for use in psychotic conditions related to dementia. Risperidone may cause heart failure, sudden death, or pneumonia in older adults with dementia-related conditions.

Do not give Risperdal to a child without a doctor's advice.

While you are taking Risperdal, you may be more sensitive to temperature extremes such as very hot or cold conditions. Avoid getting too cold, or becoming overheated or dehydrated. Drink plenty of fluids, especially in hot weather and during exercise. It is easier to become dangerously overheated and dehydrated while you are taking this medication. Risperdal can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.

Avoid drinking alcohol. It can increase some of the side effects of Risperdal. Stop using this medication and call your doctor at once if you have fever, stiff muscles, confusion, sweating, fast or uneven heartbeats, restless muscle movements in your face or neck, tremor (uncontrolled shaking), trouble swallowing, feeling light-headed, or fainting.

There may be other drugs not listed that can affect this medication. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor.
