Been on effexor (venlafaxine) xr 150mg for 7 weeks for panic disorder i started feeling better a few days ago is it normal to take that long to work.

Normal? yes: Common? maybe. In any case, enjoy the relief. You may wonder if this means you should consider it gone and stop taking it. Don't w/out Dr advice and tapering. Or, if it needs to be taken forever since it works. No, again work w/ Dr. Or, if you never needed it. Again - don't just stop. Discuss. Work together and ENJOY the good feelings! CBT can teach skills to manage or avoid your symptoms too.

Not usually: Hi Tony we usually think of response to these meds within about 4 weeks but late responses like yours are not unheard of- glad you were able to stick with it and that you're feeling better !
