Talking non-stop could be too high a dose. Ironically, it can also be too low a dose (sometimes symptoms are worse instead of better when the dose is too low). Best care practices dictate that stimulants should always be started at the lowest dose and only increased as and if needed. If she didn’t start at the lowest dose, I’d ask the doctor to lower it. If she is on the lowest dose, then see if the talking wanes over the next week or two.
As for tics, I believe that’s a side effect that will not go away. I would talk with the prescribing doctor about that right away. It may be that she’s susceptible to tics and not able to take stimulant medication.
