"this medication is amazing!! be patient and try it! all adhd medications (like any other medication for anything) have side-effects but i have learned concerta&#039;s do go away once you let your body do the talking: push through the 1-6 days of anxiety/depression/hyperactivity, etc., and be open to what it can do for you once your body gets used to it. i am 21 years old and i am on 54mg and i take a side-effect medication called intuniv xr (2mg) that cured the anxiety side-effect which i found to come about half way through the day and when the concerta was wearing off. this side effect comes about because concerta is not a gradual release but 2 releases of the medicine- it drops off and may cause anxiety for a short time during the day."
