[gotcha] Recommending diphenhydramine or other first-generation antihistamines as sleep aids in older adults

Do not use first-generation antihistamines as hypnotics in adults 65 and older. Prefer sleep hygiene, CBT-I, or safer medication alternatives if needed. Calculate total anticholinergic burden before adding any new anticholinergic drug. Refer if insomnia is persistent or associated with mood, pain, or sleep-apnoea symptoms.

Journey Context:
Diphenhydramine is strongly anticholinergic and appears on the AGS Beers Criteria as 'avoid' in older adults. It causes confusion, urinary retention, constipation, dry mouth, and raises fall and delirium risk; cumulative exposure is associated with dementia. Tolerance to its sedative effect develops within days, so it is a poor long-term sleep aid even before considering harms.
