Blue Adderall pill, round pill printed with AD on one side and 10 on the other. An Adderall Blue pill would look like a blue capsule with one clear side. It would be printed with Adderall XR 10 mg. Adderall 10mg is available as both immediate-release (IR) and extended-release (XR) formulations. Doctors will usually start patients at a low dose, such as 5mg or 10mg, that can be taken throughout the day. Adderall XR only needs to be taken once per day. Some doctors prefer Adderall IR because there are more flexible dosing options that go up incrementally, allowing them to better tailor a patient’s dose.
