A popular medication used to treat urinary incontinence may cause some troubling side effects, especially in older patients.In a case study appearing in the Dec. 4 issue of the New England Journal of Medicine, two Florida doctors report that a 73-year-old woman taking the drug tolterodine had hallucinations and significant memory impairment while on the medication. When she stopped taking the medication, the hallucinations stopped and her memory improved, according to the case study.
