I'm taking it for GAD, SAD and panic. I've been at this higher dose for about a week and feel more anxious and rapid heartbeat. Is this just a side effect from going up to a higher dose? Will it go away after a few weeks? I've read that sometimes this can happen when just starting. I want to stick with it to see if it helps, but not if it makes me more anxious forever. Can anyone help me?

I took Effexor XR for only 3 weeks at 150 mg and could not tolerate the increased anxiousness, dizziness, panic attacks. My doc said that the norepinephrine effect in the drug can cause panic disorder patients worsening anxiety. I am coming off of it and cannot wait. increasing your dose does not sound like a good idea to me.
