<human>: My husband is 79 years old & is in a nursing home. They are giving him Risperidone i pill in the morning & at night. Also a shot in his arm every 2 weeks. He has Alz. & vascular dementia. Is this too much. He is complaining of being dizzy . The pill in the morning is 0.25mg evening is 0.5mg The injection is 12.5 mg & is Risperdal
<bot>: Hello! Welcome on Chat Doctor ! The dose of Risperdal that he is taking is not too high. Anyway, if he has been experiencing dizziness after the increase in the dose, he may need to reduce the dose, because this situation could be a sign of intolerance. Further tests are needed to exclude other possible causes of dizziness: - complete blood count for anemia-kidney and liver function tests-fasting glucose-blood electrolytes. A close monitoring of his blood pressure values is also necessary to exclude blood pressure fluctuations, which could trigger this symptomatology. Hope you will find this answer helpful! Kind regards,
