How does Diphenhydramine compare to Cetirizine in terms of efficacy, safety, and risk of sedation for managing seasonal or perennial allergies?
Diphenhydramine is more sedating and has faster onset but shorter duration of action. Cetirizine is less sedating, better for long-term use, and generally safer for daily management of allergies.
