A member asked:
I just got zyrtec (cetirizine) oral drops which allow me to be alert. will it cause insomnia if i take it at bedtime? i am still afraid it may make me drowsy...

Unlikely: Zyrtec (cetirizine) causes drowsiness (usually mild) in only about 10% of the people and given your paradoxical response, it may indeed keep you awake at night. Try something else.
