What should I avoid while taking lisdexamfetamine?

https://online.epocrates.com/images/peicons/dizzy.gifLisdexamfetamine can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.
Avoid drinking fruit juices or taking vitamin C at the same time you take lisdexamfetamine. These can make your body absorb less of the medicine

from the epocrates.com link above.

it prevents proper absorbtion of the medication
