My son just got diagnosed with ADHD-combined type right before his 6th birthday 2 months ago and we are already on the 3rd med
1st Medication: Ritalin 5 mg (no change in attention, increased aggression/defiance, and regressed in some behaviors including pooping on himself at his after-school program, peeing twice in his pants, and defiantly peeing on a tree at afterschool) 10 days on it and it was immediately clear it was not working.
2nd Medication: Vyvanse 10 mg (MUCH more positive and we thought we had a winner. His attention improved a lot in school & home, he followed directions more frequently and seemed to "hear us" better, did NOT run away and hide or run off while we were transitioning between places, followed the directions, less forgetful, and played well in soccer. He did have more difficulty falling asleep initially and seemed somewhat more irritable in the mornings and in the evenings. His teacher reported that when the kindergarteners all come in and are sitting at breakfast together (they all get free breakfast...), he was ALWAYS SUPER chatty, social, and happy. His teacher noticed that he started having "quiet time" in the morning and would eat his breakfast in silence and then just watch the clock until it was time to move on. She checked on him several times and he always said that he was just being "quiet". His teacher also noticed he was much more irritable with small and big things and had a hard time recovering, when before that was never an issue.
After I heard that update, we called his doctor and took him off immediately (Friday). He has been unhinged since then....we saw his doctor today and he was quite literally rolling around the room, bouncing on the chair, interrupting me incessantly and even acted like he was going to write on the wall with the pen I was given. It was awful.
We are going to try Strattera now. I'm slightly terrified to see how he will do with this new med. If it goes badly, he could get in trouble with his after-school program and be kicked out

He normally does fine but they are not real forgiving and don't understand medication side effects. His doctor thinks that it's possible the irritation could have been worked out over time with Vyvanse and a higher dose could support him later in the day but wanted to try a different one right now. I know many of you all have been through this but it's hard. Anyone have similar experiences and have positive results with Strattera or another med?
I just hope something works for him. Sincerely, tired mama.
