Commonly Used Medications May Produce Cognitive Impairment in Older Adults.

Many drugs commonly prescribed to older adults for a variety of common medical conditions including allergies, hypertension, asthma, and cardiovascular disease appear to negatively affect the aging brain causing immediate but possibly reversible cognitive impairment, including delirium, in older adults according to a clinical review now available online in the Journal of Clinical Interventions in Aging, a peer reviewed, open access publication. Drugs, such as diphenhydramine, which have an anticholinergic effect, are important medical therapies available by prescription and also are sold over the counter under various brand names such as Benadryl®, Dramamine®, Excederin PM®, Nytol®, Sominex®, Tylenol PM®, and Unisom®. Older adults most commonly use drugs with anticholinergic effects as sleep aids. Comment: We keep seeing similar research, but our current medical record/pharmacy systems rarely include the OTC compounds patients use, so that programs to identify possible drug conflicts are not recognized
