Duration and Dosage of Adderall XR 30mg

XR is a 24 hour release. It is most recommended to follow your doctor's instructions before changing your dose on your own.

Your doctor/psychiatrist should be answering these questions. It depends how long you've been taking Adderall and how your body reacts to it. For me personally, I take 10-20mg (one pill) and it works for 3-4 hours before I take a second one. My mother takes 40mg at lunchtime and that's it for the day. I recommend not taking 60mg at once.
