Hello; first you have to stop giving him neurocetum or similar named syrup you are giving him. What is your son's weight & height? c. Atomoxetine
(acepta) is a very good medication & we can increase its dose depending on your sons responses like studies, behavior in class etc. In addition, there are other good medications like methylphenidate
also which can be prescribed if required. Do revert back for further help. Good luck.
