Switching antidepressant (tricyclic antidepressants (TCA) to serotonin and noradrenaline reuptake inhibitors (SNRIs))

From all except clomipramine

Cross-taper
  • cross-tapering starting with a low dose SNRI can usually be undertaken cautiously over 2 to 4 weeks, the speed is determined by individual tolerability

From clomipramine

Taper, stop and switch
  • if switching from clomipramine, gradually reduce the dose of clomipramine and stop. Start low dose SNRI the following day

  • cross-tapering is not recommended and should only be undertaken if specialist advice is in place, this is because clomipramine is a potent serotonin reuptake inhibitor so there is a high risk of serotonin syndrome.
