My son when 11 years diagnosed with ADHD due to a lack of concentration on studies during on October 2019 after a neurologist and psychiatrist consultation and was given Axepta 10 mg 1-1-0 daily  + evening 5 ML IQU plus syrup and now even after taking for a year in September 2020 too, doctors asked to extend another 6 months but his ADHD symptoms improved a lot from Nov 2019 itself and from within a month from Nov 2019 onwards too doing pretty well in maths, karate, chess, silambam and overall concentration too. Both Neurologists and Psychiatrists Doctors saying let’s continue the same medication for few more 4-5 years, I’m worried about prolonged axepta usage as he improved within 20 days immediately and not to stop the medication until Doctors confirms when to stop, he’s taking daily. 1) As of now no side effects, but any known side effects to internal organs would occur prolonged usage for another 4-5 years? 2) Is there any chance of ADHD return after doctors stop Medication ?
