The doc gave my son 4mg intuniv to take twice daily. I have read on on the intuniv web site that you are only to take one pill once daily. I called the doc cause after a day of taking it my son was looking like a zombie, always sleepy, and stomach hurting. I then questioned the doc about the 4mg twice a day and told them about what it said on the web site and they said it was ok to take it twice a day, but back it off to one for now. I am not going to give it to him anymore period, but my question is has anyone been told or have taken more then the one 4mg dosage. Am I correct or not on the amount to take per day?
