Hi, I was prescribed 20mg of Citalopram for social anxiety. I took it for 8 weeks and it had no effect. My doctor then increased the dosage to 30mg. I know that Citalopram takes a number of weeks to work , I've read around 6-8 weeks, but does this mean that it also takes 6-8 weeks for an increase in dose to take affect? So should I take the 30mg for 8 weeks or so and see if it works, because it's not having an effect right now after one week (besides killing my sex drive). Thanks
