Adderall and Concerta are similar in that both:
That’s where key similarities end and how these 2 medications are different begins.
Adderall and Concerta have different active ingredients.
Exactly how amphetamine/dextroamphetamine in Adderall and methylphenidate in Concerta help relieve ADHD symptoms is a mystery.
What experts do know is that both may block the re-uptake of norepinephrine and dopamine into the brain’s neurons. Norepinephrine and dopamine are neurotransmitters in the brain. Neurotransmitters help different areas of the brain communicate with each other.
By reducing the re-uptake of norepinephrine and dopamine into neurons, amounts of monoamines (another neurotransmitter) in the gaps between synapses in the brain go up. This “rebalancing” of neurotransmitters increases feelings of pleasure and happiness and helps regulate ADHD-affected regions of the brain to let people with ADHD focus better, remember more, and be less impulsive.
The dosages, forms, and generic availability of Adderall and Concerta are different Adderall comes in a few more dosages and both standard and extended-release formulas. Concerta has one formula that offers the longest, most sustained effect of 10 to 12 hours.
Concerta | Adderall | |
Forms | One | Adderall standard-release Adderall XR (extended-release) |
Dosages | 18 mg 27 mg 36 mg 54 mg | Standard release 5 mg 7.5 mg 10 mg 12.5 mg 15 mg 20 mg 30 mg XR 5 mg 10 mg 15 mg 20 mg 25 mg 30 mg |
Dosing frequency for ADHD | Once a day in the morning | Standard release 1 dose in the morning and another 4 to 6 hours later XR Once a day in the morning |
Dosing schedule | Start at 18–36 mg for adults (18 mg for children up to 17) and increase 18 mg a week up to a maximum dose of 72 mg; can start with a higher dose if already taking methylphenidate | Standard release Start at 5 mg daily (2.5 for children under 6) and increase by 5 mg a week until the optimal dose is found, typically 40 mg XR Start at 10 mg a day and increase by 5–10 mg a week until the optimal dose is achieved, typically 20 for adults and 30 mg for children up to 17 |
Availability in the body | 10–12 hours | Standard release 4–6 hours XR 7 hours |
Generic availability | No FDA-approved generic equivalent; the FDA withdrew approval for previously available generic version of Concerta Generic methylphenidate is available, but lacks Concerta’s OROS delivery system | Amphetamine/dextroamphetamine |
A big distinction between Concerta and Adderall is how the medications are released into the body and how long they last.
Concerta uses what’s called an osmotically controlled release oral-delivery system (OROS). That’s a fancy way to say that it delivers different amounts of medication at different times.
This OROS delivery system keeps Concerta in your system for up to 12 hours.
Adderall XR uses a double-pulsed delivery system. Each capsule has 2 types of drug-containing beads that release medication in 2 doses at different times to create the extended-release effect. It lasts in your system up to 7 hours.
Standard-release Adderall releases its full medication load shortly after being taken. Its effects last for 4 to 6 hours. Most people take 2 a day 4 to 6 hours apart.
Concerta isn’t necessarily stronger than Adderall or Adderall XR. It does last longer than Adderall XR, which may offer an advantage for some people.
Studies have found that the active ingredient in Concerta, methylphenidate, offers more improvement in executive and non-executive functioning, especially distractability and visual memory, compared to other ADHD medications, including Adderall. And a study done with a small number of adolescents between 16 and 19 found that participants taking Concerta showed significant improvement in visual memory and distractibility on Concerta compared to Adderall.
That could mean that if your type of ADHD is predominantly inattentive ADHD or combined ADHD, you may have better results with Concerta than Adderall. Only you and your provider though can make that decision.
On the flip side, user reviews for Adderall XR are highest compared to Adderall and Concerta on drugs.com. Adderall XR has a 7.9 average rating with 75% of users reporting a positive experience. That’s compared to a 7.2 average rating for Adderall with 65% of reviewers reporting a positive experience. For Concerta average drugs.com user review is 6.8 with 56% of reviewers reporting a positive experience.
Those are averages of course. Some reviewers report taht Concerta “is a godsend” while others say Adderall XR is “life changing.”
Concerta and Adderall costs about the same with Adderall XR costing the least of the brand-name options. With drugs.com’s discount and no insurance 100 pills cost:
Other discount programs may give you even lower costs. And if you have insurance, you should only have to pay your co-pay if the medication is covered on your plan. Your insurance provider may want you to use a generic or offer a lower copay if you use a generic.
Your insurance company also may want you to get prior authorization for Adderall or Concerta. That means your provider submits a form to show that the medication is medically necessary for you.
For more information on Adderall or Concerta pricing and whether or not you need prior authorization through your health insurance plan, call your insurance provider.

Stimulants like Concerta and Adderall can increase blood pressure and heart rate. They may be dangerous or even fatal for anyone with heart disease or abnormalities, or existing hypertension or rapid heart rate. Before taking either Concerta or Adderall, your provider should check you for the possibility of cardiac (heart) disease or a family history of heart disease. They should also assess you for a personal or family history of motor or verbal tics and/or Tourette’s Syndrome.
You should avoid Adderall and Concerta if you know you’re hypersensitive or allergic to any of their ingredients. And if you take either and have an allergic reaction, such as trouble breathing, call 911 immediately.
The FDA issues boxed warnings for some medications. The warnings let you know that the medication has a serious risk. In the case of Concerta and Adderall, both have a boxed warning for potential abuse, misuse, and addiction. Using these medications can result in physical and psychological dependence.
To protect yourself, only take your medication as prescribed and at the prescribed dose and timeframe. And don’t abruptly stop taking Concerta or Adderall. Stopping quickly can cause withdrawal symptoms, like fatigue, depression, and irritability.
If you have a personal or family history of substance abuse or addiction tell your provider and only use Adderall or Concerta with caution.
