Risperdal & Invega are two antipsychotic drugs marketed by Johnson and Johnson that have proven to be dangerous to those who take them. Risperdal (risperidone) is approved to treat schizophrenia and bipolar disorder in adults and adolescents, as well as autism in children and adolescents. Invega (paliperidone) is also approved to treat schizophrenia. These drugs are also prescribed “off label” for attention deficit hyperactivity disorder (ADHD), anxiety, sleep difficulties and depression.
Although Risperdal and Invega can provide relief by changing levels of dopamine and serotonin in the brain, they can cause serious side effects as well.
- Breast development in males – The drugs cause pregnant women to produce more milk, and the same conditions may cause adolescent boys to grow abnormal breasts, or Gynecomastia.
- Movement disorders –Dangerous side effect of Risperdal and Invega are movement disorders such as tardive dyskinesia. The symptoms of tardive dyskinesia often resemble Tourette’s syndrome or Parkinson’s disease. People with the disease cannot control their movements such as grimacing, rapid eye blinking or grunting and gasping. There is no cure for this disease.
- Diabetes – Both drugs have been linked to increased blood sugar and type 2 diabetes.
- Death from heart attacks – The FDA requires Risperdal to put a black box warning on its packaging that taking it can lead to an early death for elderly patients. Black box warnings are the strictest warnings that the FDA can require. Invega is linked to rapid heart rate.
Class action lawsuits have been filed against Johnson & Johnson for marketing Risperdal as a treatment for ADHD in adolescents. In 2013, the company agreed to pay $2.2 billion to settle the charges.
