HI, and welcome
Glad you joined us! I also have a child with ADHD/innattentive, she is 12 and doing wonderfully!
How long has he been taking Straterra? it does take 6-8 weeks to see full results, and only if they are at the target dose for about 4 weeks.
Straterra is a great med, and YES you will have to increase. What is his weight? How was it ramped? Strat is dosed by weight, not by symptoms, and will not work properly unless it is at the target dose. SIde effects of the dose being too high are not desirable either.,Target is 1.2-1.8 mgs per kilo of body weight,
for example: child weighs 55 lbs-( 25. kilo), Strat dose would be between 30-45 mgs. It would be started at 10 mgs for a few days to a week,then slowly ramped to 18, 20, 25, 30 mgs etc until target is reached.
I would suggest finding another Psych, and if necessary print the dosing info off the Strat website. Good luck and come back and share!
