Why can hydroxyzine be used for anxiety but not diphenhydramine? both are antihistamines, one derived from the other, correct?

Specializes in Clinical Psychology

Not same effects: In same class of drugs as Diphenhydramine but has antagonistic effects on several receptor sites in the brain which means it works to treat anxiety, mild depression and unhealthy thought processes.
