Key takeaways
Adderall and Adderall XR are both used to treat ADHD. Adderall is an immediate-release drug often requiring multiple doses per day, while Adderall XR is an extended-release drug taken once daily.
Adderall lasts about four to six hours and is approved for ADHD and narcolepsy, whereas Adderall XR can last up to 12 hours but is only approved for ADHD.
Both have identical risks and warnings, and switching between them should only be done with guidance from a healthcare provider.
If you or your child has been diagnosed with attention-deficit hyperactivity disorder (ADHD), your healthcare provider may recommend a stimulant medication to boost neurotransmitters that improve focus and alertness. Adderall (amphetamine-dextroamphetamine) is a popular prescription drug that is available in different forms. Depending on your condition, a healthcare provider may prescribe Adderall or Adderall XR. Both forms of Adderall contain the same active ingredients and work in much the same way. However, they have differences in formulation as well as how soon you experience their effects and how long those effects last.

What are the main differences between Adderall and Adderall XR?
The main difference between Adderall and Adderall XR is that Adderall is an immediate-release drug and Adderall XR is an extended-release drug. This means that the active ingredients, a mix of amphetamine and dextroamphetamine, are released more slowly over time with Adderall XR and more quickly with regular Adderall.
Sometimes called Adderall IR, immediate-release Adderall usually needs to be taken multiple times per day, whereas Adderall XR can be taken once daily. That’s because the effects of Adderall last for around four to six hours, while those of Adderall XR can last up to 12 hours. Some people may prefer the shorter-acting effects of regular Adderall, especially if they only want to manage symptoms during work or school.
Another difference is that Adderall comes as an oral tablet while Adderall XR is an oral capsule. Adderall tablets can often be split or crushed and mixed with food. Adderall XR capsules are typically swallowed whole, but they can be opened, allowing a person to sprinkle and mix the beads with applesauce.
Regular Adderall is available in more strengths than Adderall XR. Adderall is available in strengths of 5 mg, 7.5 mg, 10 mg, 12.5 mg, 15 mg, 20 mg, and 30 mg, while Adderall XR is available in strengths of 5 mg, 10 mg, 15 mg, 20 mg, 25 mg, and 30 mg.

Compared to other ADHD medications like Ritalin (methylphenidate), amphetamines have a greater chance of decreasing appetite. Other side effects may include abdominal pain, diarrhea, agitation, dizziness, and headache.
Adderall and Adderall XR can also increase heart rate and blood pressure. These side effects may be more serious for those with preexisting heart or blood pressure problems.
Both Adderall and Adderall XR also have a boxed warning on their labels for abuse, misuse, and addiction. Both are Schedule II controlled substances. Therefore, it’s important to only take these medications as prescribed.
Switching between Adderall and Adderall XR
It’s possible and relatively straightforward to switch between Adderall and Adderall XR. However, the switch should always be made by a healthcare provider, never on your own. Although prescription products contain the same active ingredients, you’ll still need a new prescription.
Switching from immediate-release Adderall to Adderall XR is usually a direct conversion. In other words, people who take multiple doses of immediate-release Adderall can take the same total daily dose of Adderall XR taken once in the morning.
Still, a healthcare provider may want to personalize the dosage. They may prescribe the lowest effective dose and gradually increase it over time, depending on how you feel. If you’re being switched to regular Adderall from Adderall XR, there’s no set conversion. However, the total dose will likely be split across the day.
Insurance coverage and cost
Adderall costs about $916 for 60, 20 mg immediate-release tablets without insurance or discounts. Adderall XR costs about $339 for 30, 30 mg capsules. A SingleCare prescription discount card may help you save on the retail cost of your prescription medications.

The cost of brand-name and generic Adderall and Adderall XR varies by pharmacy and location. It’s common for insurance plans to require prior authorization for stimulants due to controlled-substance regulations, which can delay coverage. A SingleCare coupon for Adderall or Adderall XR can help lower the out-of-pocket costs of your medication at the pharmacy counter, which can be helpful if you have to take on the total costs while waiting for insurance to approve coverage.
Which is better: Adderall or Adderall XR?
Adderall and Adderall XR contain the same active ingredients that can help treat symptoms of ADHD. Because ADHD treatment is personalized to your specific symptoms and response, either form of Adderall may work for you. That said, extended-release Adderall has some benefits that immediate-release Adderall doesn’t.
For example, Adderall XR may be better for people who:
- Prefer once-daily dosing with effects that can last throughout the work or school day
- Have trouble remembering a midday dose, or don’t want to carry a controlled substance to work or school
- Have difficulty swallowing pills, as Adderall XR capsules contain beads that can be combined with soft foods like applesauce
- Experience “crashing” with regular Adderall IR
On the other hand, immediate-release Adderall may be a better option if you prefer flexibility. For example, you may only need to manage symptoms on school days or during specific hours. It can also be helpful if you want a shorter-acting dose that interferes less with sleep.
Whether you are prescribed Adderall or Adderall XR depends on your overall condition and symptoms. The dosing of these drugs is highly individualized and needs to be adjusted over time in some cases. Talk to your healthcare provider to discuss your potential treatment options.

Expert takeaway
One of the most common reasons people switch from immediate-release to Adderall XR is the crash. If you’re feeling irritable or foggy at the same time every afternoon, the medication may be wearing off too quickly, which could be solved by switching to the XR version for longer-lasting effects.
