    • Switching between SSRI to SSRI needs crosstapering.
      To simplify things, remember these 3 points:
      1) No antidepressant can be stopped and replaced by another drug suddenly at regular dose
      2) If MAO is involved than wash-out is must
      3) In all other cases, taper or crosstaper

      These 3 points will help you to answer these questions.
      This is from my notes. Hope this helps.
