TIcs and adhd

My son has been on ritalin for 12 months he is now 6 and the last week he has just developed eye movements that i was concerned might be a tic. He is extremely anxious , especially when on his medication in strange unfamiliar settings but does quite well at school and has lots of friends.
He has been out of routine of late with school holidays and 10 weeks ago had a increase in medication to 1 tab in the morning 1/2 at lunch and 1/2 at 3.30 pm.
I am extremely concerned that he is developing tourettes or does this mean it has always been there?

It is one of the side effects of Ritalin perhaps you should ask your Doctor for a new evaluation of the Med, if you ever decide to let him be on Natural Remedies, it has been shown in studies that food supplements have the same efficacy as Ritalin and a Muliple Vitamin-mineral with B Complex and Vit C also Fish oil, would be good, a lot of Parents are trying this now and their children and not getting the bad side effects that Ritalin and the other meds have. Good luck

they are tics from stimulants, unless he had rapid eye movements before starting ritalin then it could be genetic...my sons tics where full body moments to where his phsyciatrist thought he had austistic type symptoms...only got worse on other med like concerta, strattera on the other hand did not cause tics at all on my son, but it didn't work to well.for focus..and it is not a stimulant..im trying natural approach and while i see some improvement inattention is still pretty bad, probably going back to strattera and see if it can work albeit not optimal as my son has non verbal learning disability dx as well which overlaps with adhd and does not respond well to stimulants....
