Which medications can worsen thinking, memory, behavior, or function?
Many medications may cause memory impairment, drowsiness, and confusion. Make sure that you know and keep track of all the medications your loved one is taking, including prescriptions, over-the-counter medications, vitamins, herbs, and supplements. Review these medications with their doctor. When possible, stop or lower the dose of medications that are causing problems. There are a variety of medications that can produce impairments in thinking and memory, including anticholinergic medications; antidepressants; antihistamines; antipsychotics; anxiety medications (benzodiazepines); dizziness and vertigo medications; incontinence medications (antispasmodics); migraine medications; muscle relaxants; narcotics (opioids); nausea, stomach, and bowel medications; seizure medications (anticonvulsants); sleeping medications; tremor medications; and herbal remedies. Consider anesthesia and cancer treatments carefully. Lastly, note that cholesterol-lowering medications do not cause memory problems.
