1 week is that usual time
Thanks for using health care magic for posting your query.
I have gone though your question and I can understand what you are going through.
Vyanase is a stimulant medicatio having lesdexamphitamine. It is used for ADHD
and is a good drug. Response should become apparant in 1 week of its use. If there is a good response then the dosage needs to be hiked gradually. Gradual increase in dose may not harm your son.
is another drug which can be used if your son is not tolerating vyanase.
Hope I am able to help you with your concerns.
If you have any further queries i will be more than glad to help you.
If not you can close the discussion.
