hi.post surgery bleeding is not related with adderall but if you are on this drug since long better not to stop it abruptly as it can make you uncomfortable.Do inform the doctor about intake of adderall.
Bhups1 is right, Adderall would not have an affect on post surgical bleeding, and it's a medication that you need to take on a regular basis, according to your doctor's instructions. If you stop, you can suffer withdrawl symptoms
