Both are benzodiazepines and act very similar to each other. One important thing is that you really shouldn't substitute one for the other. The work at different specific recptor sites in your body and if (for example) you are dependent on xanax, you can actually withdraw from it even if you are taking ativan. I worked as a nurse in an ICU for 3 years and saw this firsthand. Whenever someone came in who had been on xanax, we kept them on it to prevent withdraw. If we just gave them ativan, they went through xanax withdraw.
