Ritalin is not dosed by weight, but by symptoms. Did he start lower and work up to 30? How does he handle the 30?
The long acting Ritalin are Ritalin LA (10 hour) and Ritalin SR(8 hour). We used both. The LA definitely last longer than the SR.
Hi,
My son (10yrs, 81lbs) is on Ritalin LA 30. It may need to be upped this year. Our doc said it is dosed by weight initially (just to get a starting dose) and then adjusted up or down by symptom relief. My daughter is on Ritlalin LA 20 and is about 67lbs. It's too much for your son if he is a zombie, not himself, can't sleep, talks too much, and not getting the focus he needs. Those are the indications that the dose is wrong. However, most kids do need time to adjust (about a week or two). Wow, that was a long way to give you a round about answer. Good luck.
My son is 6 and 40 pounds. He is on Ritalin LA 30mg and has been since he was about 30 pounds. He also takes 10mg of short acting ritalin in the afternoon.
His doctor mentioned uping the dose at our last visit, but then decided because of his weight not too!
