How long do withdrawal symptoms last from lexapro (escitalopram)? I have taken 5 mg/day for 1.5 years and have been off for 2 wks. Withdrawal has been difficult.

2-4 weeks. That is a low dose so you must be very sensitive to change. It takes the brain a little while to adjust to new serotonin levels. 2-4 weeks should be plenty of time for this adjustment. You are through the most difficult phase.
