If you or your child has been diagnosed with ADHD (attention deficit hyperactivity disorder), a stimulant drug may be recommended to help relieve symptoms. Stimulant medications work by blocking the reuptake of dopamine and norepinephrine in the brain. As a result, these drugs help 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, your doctor may prescribe Adderall or Adderall XR. Your doctor may also recommend behavioral therapy on top of prescription ADHD medications.

Both forms of Adderall contain the same active ingredients and work in much the same way. However, they have differences in formulations as well as how soon you’ll experience their effects and how long their 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 (d-amphetamine and l-amphetamine) are more slowly released over time from Adderall XR compared to Adderall.

Sometimes called Adderall IR, immediate-release Adderall needs to be taken multiple times per day whereas Adderall XR can be taken once daily. Effects may wear off sooner with Adderall versus Adderall XR, which has a more gradual effect throughout the day. The effects of Adderall last for around four to six hours while those of Adderall XR can last up to 12 hours.

It takes about seven hours for Adderall XR and around four hours for Adderall to reach maximum levels in the blood. In this way, some people may experience effects faster with Adderall than with Adderall XR. However, Adderall XR can be beneficial for some people who experience “crashing” with regular Adderall.

Another difference between Adderall and Adderall XR is that Adderall comes as an oral tablet while Adderall XR is available as an oral capsule. Adderall is available in strengths of 5 mg, 7.5 mg, 10 mg, 12.5 mg, 15 mg, 20 mg, and 30 mg. Adderall XR is available in strengths of 5 mg, 10 mg, 15 mg, 20 mg, 25 mg, and 30 mg.

Conditions treated by Adderall vs. Adderall XR

Both forms of Adderall are FDA-approved to treat ADHD. ADHD is a chronic mental disorder that can affect children, adolescents, and adults. The most common symptoms of ADHD include inattention, impulsiveness, and restlessness. As CNS (central nervous system) stimulants, Adderall can help balance brain chemicals to improve focus.

Adderall is also approved to treat narcolepsy, a sleep disorder that involves excessive daytime drowsiness and sudden sleep attacks. People with narcolepsy have disrupted sleep-wake cycles that can affect their daily work and social lives. Although Adderall XR is not usually prescribed for this purpose, Adderall IR can help alleviate these symptoms and improve wakefulness.

Off-label uses of Adderall may include treatment of depression and/or anxiety, especially in those who already have ADHD. Approximately 75% of adults with ADHD also have another condition. Some practitioners may prescribe the use of a stimulant with an antidepressant for treating both ADHD and depression. Other studies have found that stimulant medications like Adderall can also be effective for treating ADHD with anxiety.

Is Adderall or Adderall XR more effective?

Adderall and Adderall XR contain the same active ingredients that can help treat symptoms of ADHD. Because ADHD treatment is personalized toward your specific symptoms and response to drugs, either form of Adderall may work for you.

Some adults and children can forget to take their second dose of Adderall later in the day. This could result in effects dropping off throughout the day. Adderall XR has the advantage of once-daily dosing with effects that can last throughout the work or school day.

Adderall XR has good tolerability and may produce less adverse effects, especially in people with heart or blood pressure problems. Some studies have found that extended-release Adderall is useful for those with high blood pressure (hypertension). Adderall XR was also found to have long-term safety and effectiveness for treating ADHD.

Adderall XR capsules contain small beads of drug. Some doctors instruct their patients to open the capsules and place the beads in soft foods like applesauce. For those who have trouble swallowing medication, Adderall XR can be an effective treatment option.

Whether you are prescribed Adderall or Adderall XR depends on your overall condition and symptoms. Dosing of these drugs is highly individualized and needs to be adjusted over time in some cases. Talk to your doctor to discuss your potential treatment options.
