Risperdal | Lawsuits, Lawyers | Side Effects: Neuroleptic Malignant Syndrome (NMS), Stroke, Tardive Dyskinesia

Risperdal (Generic: Risperidone) has been linked to Diabetes; prompting the FDA to request that Johnson and Johnson issue a warning to patients and prospective patients. In a recent study, Risperdal increased a patients chances of developing diabetes by about 50 percent compared with older antipsychotics.

Risperdal has also been linked to Neuroleptic Malignant Syndrome (NMS), Stroke and Tardive Dyskinesia. There have been 37 reports of stroke or stroke-like events, including 16 deaths linked to Risperdal. In April 2003, Johnson & Johnson sent warning letters to U.S. Physicians citing the drug’s elevated risk of stroke in elderly patients.

Neuroleptic Malignant Syndrome (NMS) is a potentially fatal syndrome involving muscle rigidity, and irregular blood pressure and irregular pulse. Tardive Dyskinesia is a central nervous system disorder, which results in involuntary movement of the limbs and twitching of the face and tongue. Risperdal is a medication that treats symptoms of Schizophrenia. Medications also know as conventional antipsychotics were originally introduced in the 1950s.

Risperdal is a newer atypical antipsychotic drug prescribed to help people combat Schizophrenia. Risperdal is manufactured by Jannsen Pharmaceuticals, a division of Johnson & Johnson. Risperdal has been known to cause irregular heartbeats, muscle weakness and spasms, high fever, constipation, weight gain and headaches. Schizophrenia is a serious mental illness that affects thousands of people everyday.

This illness results in the inability to manage emotions, make decisions and related to others. The American Psychiatric Association says that schizophrenia is “one of the most debilitating and baffling mental illnesses”. Schizophrenia is caused by an imbalance of chemicals in the brain. Stress, heredity, drugs, other medical illness and physical injury to the brain also can cause schizophrenia.

Dopamine and Serotonin are the two main imbalances of brain chemicals that cause this illness. Dopamine controls emotions, motivation and movement. Regulation of mood, sleep and appetite are controlled by Serotonin. An individual who suffers from Schizophrenia have abnormalities in Dopamine and Serotonin.
