Lithium side effects in elderly bipolar outpatients.

A group of 19 geriatric bipolar lithium patients were interviewed in order to assess the incidence, bothersomeness and intensity of medication side effects. The role of subject variables was also examined. Most often reported side effects included excessive thirst, hand tremor, excessive urination and dry mouth. Although many side effects were experienced, these effects were generally tolerated with minimal intensity and bothersomeness. Results indicate that with proper precautions and monitoring, lithium can be safely administered to geriatric bipolar patients.
