A member asked:

Took 25mg hydroxyzine. not really working for itchiness. how long should at most to wait too see an effect? gave me runny nose also used for anxiety.

A doctor has provided 1 answer

Six hours.: Hydroxyzine is dosed every six hours as needed. So if you see no benefit after six hours, you can take another dose. Realize that it can make you groggy, so don't take it if you have to drive someplace or do something important.
