Adderall vs. Adderall XR
See how Adderall and Adderall XR compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Adderall XR only needs one dose a day, while regular Adderall usually needs two or three doses spaced four to six hours apart.
Adderall is FDA-approved for both ADHD and narcolepsy, but Adderall XR is only approved for ADHD, so using XR for narcolepsy is off-label.
Generic Adderall typically costs far less out of pocket each month than Adderall XR, though insurance often covers both for ADHD.

Adderall vs. Adderall XR Pros and Cons
Adderall
Adderall IR is the original amphetamine formula, taken multiple times a day and widely available as a low-cost generic. It gives more flexibility to fine-tune timing but requires remembering extra doses during the day.
Pros
FDA-approved for narcolepsy as well as ADHD
Approved for children as young as 3
Dose timing can be adjusted throughout the day
Cons
Wears off in about 4 to 6 hours, needing 2 to 3 doses daily
Easy to forget a midday or afternoon dose
More noticeable ups and downs as each dose wears off
Adderall XR
Adderall XR delivers the same amphetamine mixture in one extended-release capsule, so most people only need a single morning dose. It is approved only for ADHD, and its once-daily design leaves less room to adjust coverage later in the day.
Pros
Only one dose needed each morning
Steadier release may reduce the crash some people feel with IR
Capsule beads can be sprinkled on food for those who can't swallow pills
Cons
Not FDA-approved for narcolepsy
Not approved for children under 6
Costs roughly $200 to $350 a month without insurance, well above generic IR's price
