ABSTRACT

Myasthenia gravis is an autoimmune disease that affects the neuromuscular junction. It causes generalized muscle weakness that may include the respiratory muscles, potentially leading to a medical emergency known as a myasthenic crisis. This is a case report of a rare incident of a myasthenia gravis exacerbation after administration of the oral antipsychotic risperidone to a schizophrenic patient. Few similar cases have been reported. Although rare, such incidents are dangerous as physicians could easily confuse myasthenia gravis symptoms with extrapyramidal side effects of antipsychotics. This concern should be addressed not just with risperidone but rather with any other antipsychotics that exhibit anticholinergic side effects.
