In brief: Generally 2-4 weeks
Most antidepressants take 2-4 weeks.
Some people, esp with panic attacks may notice worsening before improvement. If there is no improvement after 4 weeks adjustments or med changes would be indicated. Tell your prescriber if you feel worse initially as there might be something to help.
