Do you get protein in urine from vyvanse (lisdexamfetamine)?

Not likely : That is not a typical side effect from that medication. Proteinuria can have a wide range of causes and some are more serious than others. A full workup will likely provide the answer and should be done to rule out more serious causes. If there is decreased kidney function the dose of vyvanse (lisdexamfetamine) will need to be decreased.
