New evidence suggests that actually antidepressants "start" working from 2-3 weeks but for the full "clinical" effect we may have to wait 4 weeks. In addition, the resposne we see after 4 weeks may not be the full response as as my colleague has rightly pointed out, it depends on your body and you may need a higher dose.

It may take up a minimum of 6 weeks for Citalopram to start its effect. However it can take longer in some individuals. I recommend you wait till 6 weeks and if there is no effect, i recommend you consult your doctor to increase the dose.

In the meantime, i hope that the advices in this article will help you:
