I am on multiple medications geodon depakote and was on citalopram I am having troubles maintaining a erection which is a common side effect of citalopram I have been off citalopram for about 3 weeks now and it still hasnt come back.. its possible that the geodon causes this as well but its like 1 in 1000 that you get that effect from it so I guess my question is how long do you have to be off citalopram for the effect to go away
