OK: It is ok, but it might not be completely effective. Hydroxyzine and Ativan (lorazepam) work through different mechanisms of action. Hydroxyzine is a potent antihistamine, which leads to sedation and decreased anxiety. Ativan (lorazepam) works through the GABA system (more like alcohol). Withdrawal from Ativan (lorazepam) will be mitigated to some extent, but not completely by using hydroxyzine. In time, should be ok.
