The present case report narrates the case of a 60-year-old woman with a past medical history of schizophrenia, who exhibited parkinsonism symptoms subsequent to the administration of risperidone - a typical antipsychotic drug that impacts dopamine and serotonin levels. The patient presented with pill-rolling tremors, bradykinesia, rigidity, and weakness in the left upper limb, and was diagnosed with Parkinsonism following a physical examination by a physician. The patient was subsequently referred to a neurologist, who recommended switching from risperidone to Riscon Plus, a medication that combines risperidone with Trihexyphenidyl, an anticholinergic drug that improves muscle control and reduces stiffness. This case report emphasizes the significance of vigilant monitoring for the symptoms of Parkinsonism in individuals consuming dopamine-blocking drugs and the possible advantages of shifting to alternate treatments that can alleviate such undesirable consequences.
