[gotcha] Recommending diphenhydramine \(Benadryl\) or other first-generation antihistamines as a nightly sleep aid, especially for older adults

Avoid first-generation antihistamines as hypnotics, particularly in adults ≥65; they are anticholinergic and raise risks of confusion, falls, urinary retention, constipation, and dementia. For insomnia, suggest sleep-hygiene/CBT-I first, then discuss safer options with a clinician.

Journey Context:
Diphenhydramine is ubiquitous in 'PM' pain relievers and OTC sleep aids, but the AGS Beers Criteria list it as potentially inappropriate in older adults. Tolerance develops within days, and the anticholinergic burden accumulates across allergy, bladder, and psych meds. Agents often miss that a 'harmless allergy pill' is a contributor to delirium and falls; second-generation antihistamines or non-pharmacologic sleep strategies are preferred.
