Risperdal also affects thinking, judgment or motor skills that’s why it is important to take precautions before operating machinery and vehicles if Risperdal affects you in this way.

Risperdal – Getting Legal Help
Even if most medicines are expected to have side effects, it is the duty of the manufacturer of these medicines to inform the medical community and the public of known risks associated with the drugs they produce. Failure to give adequate warning to the public and the medical community of the dangers of the drug makes the manufacturer liable under product liability for any injury that may be caused by their product.
If you or your loved one has suffered any of the dangerous symptoms or unusual reaction after taking Risperdal, go to your doctor or the hospital as soon as possible. You may also consider consulting with an experienced attorney in order to get more information regarding your rights and possible remedies for the injuries you suffered because of the use of Risperdal.
