It's not likely at all after only three doses. It is common when starting some medications (like SSRIs) to feel a little more nervous than usual, but it passes after a couple of weeks and then you get the good benefitrs from the meds. It would be helpful to try a medication for at least two/three weeks before giving up because of side effects that will most likely lessen or disappear. It's also common for a doctor to prescribe something, temporarily, to help counteract the initial side effects of SSRIs or other antidepressants for panic disorder, usually a benzodiazepine like Xanax or Klonopin. Maybe you should ask your doctor about this.
