My son has been on 18mg of Concerta for 6 months now. All of a sudden he has started clearing is throat, it seems to start in the afternoon but he does it non-stop until bed time. He has done this before even before concerta so I would give him Claritin and it would go away. Claritin doesn't work anymore. I was wondering if this is normal that a tic would start 6 months after taking it and will it go away?? I would hate to change his meds b/c he is doing really well on Concerta.
