Go to the ER : If you really took 900 mg of vyvanse (lisdexamfetamine) you can expect to have very serious cardiac side effects and you need to be seen ASAP. If you meant to say 90 mg that is different story. You may still have rapid heart beat, irregular heart beat, and elevated blood pressure. If you are taking any other medication you have the potential for interactions. Consult with your provider who prescribed the vyvanse (lisdexamfetamine).

Vyvanse (lisdexamfetamine) too much: If you meant 90mg., you might be ok but slightly over the limit of 70mg. If you meant 900mg., head on to the ER.
