How long will it take atarax (hydroxyzine) HCl 50mg 2 times a day taken for a month to leave my system?

Why????? why you want atarax (hydroxyzine) to leave your system is not part of a drug screen it is not classified drugs in spite of that it depends how much you are taking and for how long and it depend on the health of your liver and kidney. so 100mg a day for a month it might take two weeks give or take pending the status of your liver and kidney.
