my doctor changed my meds.
No. The only similarity is that most docs agree that Xanax and Klonopin are the two most potent benzos, and are roughly equal on a mg by mg basis (ie 1mg Xanax = 1mg Klonopin). Some doctors disagree and think Klonopin is slightly more potent, but the difference is not huge.
Xanax is a short-acting benzodiazepine. It's half-life (which tends to be 1/2 to 1/3 of the time it has active effects that are noticable) is an average of 8 hours.
It reaches peak plasma levels after 1-2 hours, depending on the person.
Klonopin is a long half-life, 34 hours (plus another 19-60 for active metabolites). Because it's long acting, it has lower abuse potential, and is usually used to prevent panic attacks and anxiety attacks. It reaches peak plasma on average of 2-4 hours after oral administration, again, depending on the person.
If you use Xanax to stop a panic attack and it's been working, I'd question your doc as to why she or he switched you to Klonopin. If you were taking Xanax for general anxiety, however, it makes sense to switch to a longer acting drug so that you don't experience the "rebound anxiety" that regular release Xanax can cause.
If I misread your question and your doc switched you TO Xanax from Klonopin, then that's a whole different matter. But I'll refrain from explaining the reasoning for this since this is already a very long answer.
