Concerta vs Adderall: what they are and how they work

Adderall and Concerta are similar in that both:

  • Are Schedule II stimultant instead of non-stimulant medications for ADHD
  • Are FDA-approved to treat ADHD and narcolepsy (a sleep disorder) — Adderall in 2002 and Concerta in 2000.  Adderall is approved to treat ADHD in people 3 and older and narcolepsy in people 6 and older. Concerta is approved to treat ADHD in people 6 to 65  and narcolepsy (as methylphenidate). 
  • Both act on neurotransmitters in the brain to help alleviate the 3 major symptoms of ADHD: impulsivity, hyperactivity, and lack of focus and attention. 

That’s where key similarities end and how these 2 medications are different begins.  

The active ingredients in Adderall vs Concerta and how they work for ADHD

Adderall and Concerta have different active ingredients.

  • The active ingredient in Adderall is amphetamine/dextroamphetamine, sometimes called amphetamine/dextroamphetamine salts. 
  • The active ingredient in Concerta is methylphenidate; the same activate ingredient in Ritalin and other ADHD medications. 

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. 

Adderall vs Concerta dosage, form, and generic availability 

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.

Generic methylphenidate is available, but lacks Concerta’s OROS delivery system

How long Adderall and Concerta take to work and how long they last

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. 

  • 22% is delivered when the outer capsule dissolves quickly after you take it.
  • Most of the remaining medication is delivered as the capsule’s 3 inner compartments dissolve at different times of the day and your intestines absorb the compartments to release medication into your body. 

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.

Is Concerta stronger than Adderall?

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. 

What do real people say about Adderall vs Concerta

On the flip side, user reviews for Adderall XR are highest compared to Adderall and Concerta on 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 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.”

How does the cost of Concerta vs Adderall compare?

Concerta and Adderall costs about the same with Adderall XR costing the least of the brand-name options. With’s discount and no insurance 100 pills cost:

  • Concerta: between $1,368 and $1,572 or $13.68 to $15.72 per capsule
  • Standard release brand-name Adderall: $1,138.63 or $13.38 per tablet
  • Generic amphetamine/dextroamphetamine extended release: roughly $28 to $36 or $.28 to $.36 a capsule
  • Brand-name Adderall XR: $759.54 or $7.60 per capsule
  • Generic amphetamine/dextroamphetamine extended release: roughly $53 or $.53 a capsule

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.
