My 8 year old step daughter was diagnosed with ADHD. She has been prescribed Concerta. The school nurse administers it to her daily Mon thru Fri at school. However, my daughter does not get it during the weekends or breaks even if the break is for an extended period. Ex; During a two week break over winter her mother did not administer the Concerta to her. When school resumed, the medication was administered as if she had never stopped taking it. This caused an adverse reaction and she had to stop taking it for one wek then start taking it again as if she had just started... lower doses... So my question is... Is it okay to miss doses at any time? It doesnt seem that this is heathly. It really worries me.
