We live in the US. He’s is 65lb which I think is around 30kg. His biggest challenges are impulsivity and inattention. The Straterra alone helped calm the impulsive behaviors a bit – fewer outbursts, less interruptions, maybe slightly calmer. However it did nothing to help him focus for any length of time or complete his classwork. He was literally getting nothing done and all his work was coming home. Vyvanse alone helped his focus, stay on task and complete work but it was making him edgy and causing repetitive OCD type behaviors like picking his skin until it bled, blinking his eyes repetitively, repeating noises over and over, etc. When we added Straterra to the Vyvanse those behaviors stopped. To your point, meds do not solve the issues but they can put the child in a space where they are more focused, more calm, and are then receptive to other inputs such as therapy. It “takes the edge off” so they are able to then learn and grow.
