My 16 yer old son was on 20mg of citalopram and responded really well, he was social and happy after 10 weeks on them. I cant remember when they started kicking in but it was a steady climb. Now he has been put up to 30 and after 2 horrendous weeks of side effects we are currently on week 4,5. he is not half as bright as he was before the increase. he had 4 great days last week but has had 3 bad days in a row where he is barely able to get out of bed. My question is how long should an increase take to take effect. Do we stick it out for longer or do we ask to get the meds reduced? Any help appreciated because I am getting really worried. He sees his therapist tomorrow and his doctor in a week.
