a. diphenhydramine (Benadryl)
b. chlorphenirmine (Chlor-Trimeton)
c. hydroxyzine (Atarax, Vistaril)

d. Second-generation H1-receptor blockers re fexofenadine (Allegra), cetirizine (Zyrtec), and loratadine (Claritin). Terfenadine (Seldane) and astemizole (Hismanal) were taken off the market in 1999 because of the development of lethal cardiac arrhythmias. Second-generation H1-receptor blockers do not cross the blood-brain barrier and thus cause less sedation than the first generation agents.
