I'm really not 100% sure. I am at work (and have people looking over shoulder) otherwise I would look it up for you. I do believe that xanax is faster acting but doesn't last as long as ativan. I don't think you are mixed up. Ativan has a longer half life than xanax. Is there a reason you ask??
And sorry, to answer your original question. I prefer ativan as it does not give me rebound anxiety. That's just me though. Take care.
Good Morning Hopegirl,
I will try to answer your question but please remember I am not a professional.
Xanax: Peak plasma concentration is achieved in 1-2 hours. It is the drug with the faster onset of these 2 meds you are asking about.
However it has a half life of 6-12 hours.
Half-life: time taken for blood concentration to fall to half its peak value after a single dose. . This time may vary considerably between individuals.
Ativan: Peak plasma concentration peaks at around 2 hours.
The half life for Ativan is 10-20 hours so it is the longer acting. Reference: PDR
You are right in your statement. Take care and keep posting.

I knew someone would have the skinny on it!
Hopegirl, I hope this has helped out.
Oh My Big Sis, I did not know you had such talent. Your a poet and didn't know it.
Hugs and sleep well...........
Percy and I understand, not to worry.
Well if I had to choose between Ativan and Xanax I guess I would choose the one that worked the quickest.
