s actually an approved route of
administration that allows for a slightly quicker onset
of action versus orally (especially good in the even
of a panic attack or something like that).
Unless the dose of Ativan was a bit stronger, you likely will find that overall the Xanax works better. They're both benzos and both share tolerance and dependency (when taken regularly), so I guess I just don't understand the switch, especially if the Xanax was working for you.
