A member asked:

Just moved up to 40mg of vyvanse (lisdexamfetamine) today. i'm having racing thoughts. is the dose too high or am i just not adjusted to it yet and it'll get better?

Side effect: Vyvanse (lisdexamfetamine) is given for ADD/ADHD to improve concentration. Typically it has a calming effect for that reason. You're right to question having racing thoughts. Please speak to your prescribing doctor without delay to review this dose. Vyvanse (lisdexamfetamine) should not make you feel hyper or "racy." Best wishes.
