Fexofenadine is a non-sedating antihistamine, causing less drowsiness and cognitive impairment compared to sedative antihistamines like diphenhydramine.
Fexofenadine, classified as a second-generation antihistamine, typically does not cause drowsiness or cognitive issues, unlike first-generation antihistamines.
