My DS who is now 20 was given citalopram and then sertraline when he was 15. He has had problems with ED since then. I understand it is not uncommon; but doctors don’t seem to have much experience or any answers. Have any of you got partners or sons who have had this? and have they had any successful treatment. He is so depressed and upset about this he says his life is ruined and I really don’t know which way to turn as he says the doctors don’t have any experience and only want to give him viagra. There is a lot on the internet about post SSRI problems but can’t see any answers…
