A member asked:

Panic disorder triggered by metilfenidate. very good response to effexor (venlafaxine). is it possible that it's just a chemical umbalance, that will soon correct?

7 doctors weighed in across 2 answers

No: It takes time for Effexor (venlafaxine) to work. It often takes two weeks for it to begin to work and the dosage may have to be adjusted and that will take additional time.
