Which antihistamine is recommended to avoid in elderly patients?

Benadryl, known generically as diphenhydramine, is recommended to avoid in elderly patients due to its sedative properties and anticholinergic effects. In older adults, the use of anticholinergic medications can lead to increased risks of confusion, falls, and other cognitive impairments. Furthermore, Benadryl can cause sedation, which can exacerbate mobility issues and increase the risk of accidents.

In contrast, other antihistamines like Zyrtec (cetirizine), Claritin (loratadine), and Allegra (fexofenadine) are often considered safer for the elderly as they have fewer central nervous system side effects and lower anticholinergic activity. This makes them more suitable options for managing allergies in older populations, where safety and cognitive function are major considerations.
