Risperdal (risperidone) is among a class of drugs known as atypical antipsychotics, which also include Zyprexa and Seroquel. The FDA has approved Risperdal for the treatment of schizophrenia, mania, bipolar disorder and irritability in autistic children and adolescents.
Serious side effects
Risperdal can increase the risk of both extreme weight gain and hyperglycemia (high blood sugar). Because both of these conditions are risk factors for diabetes, Risperdal also places patients at risk for this disease.
In April 2005, the FDA asked Janssen Pharmaceuticals to add a “black-box” warning to its label. The agency had found that elderly patients with dementia who take Risperdal had a higher risk of dying than those taking a placebo.
Researchers have identified several additional Risperdal side effects, including an increased risk of stroke and other cardiovascular problems. Janssen sent a letter to doctors in April 2003 which informed them that at least 37 patients have suffered strokes after using Risperdal. Out of these patients, 16 later died as a result of their Risperdal side effects.
Studies have also linked Risperdal to several movement disorders, including tardive dyskinesia, neuroleptic malignant syndrome and extrapyramidal symptoms.
Lawsuits over Risperdal
At least 700 patients have filed Risperdal lawsuits because of side effects they suffered after using the drug. In addition, the attorneys general of several states have filed lawsuits against Janssen, alleging that the company illegally marketed Risperdal for uses not approved by the FDA.
