ADHD Medications for Adults and Children: Which Are Best?

The number of medications for attention deficit hyperactivity disorder (ADHD or ADD) is overwhelming at best, and the process for selecting the best ADHD medication for you or your child is incredibly personal.

The ADHD medications prescribed to both children and adults are categorized as stimulant — amphetamine or methylphenidate — or non-stimulant. Stimulants are considered the treatment of choice for ADHD. Non-stimulants are prescribed to patients who don’t tolerate or see benefits from stimulants. Certain non-stimulants, particularly alpha agonists, are prescribed with medication to treat symptoms that stimulants do not alleviate. The most popular ADHD medications among ADDitude readers include (in alphabetical order):

  1. Adderall XR (amphetamine)
  2. Concerta (methylphenidate)
  3. Dexedrine (amphetamine)
  4. Evekeo (amphetamine)
  5. Focalin XR (dexmethylphenidate)
  6. Quillivant XR (methylphenidate)
  7. Ritalin (methylphenidate)
  8. Strattera (atomoxetine hydrochloride)
  9. Vyvanse (lisdexamfetamine dimesylate)

Many parents and adults are similarly confused by these and other treatment choices for ADHD. Our ADHD medication chart can help you learn the facts about both stimulants and non-stimulants in the treatment of ADHD. The Food and Drug Administration (FDA) requires that a medication be given a different name according to its form (capsule, tablet, liquid, patch) or release mechanism (released immediately or over an extended period of time).1 Here’s an example: The ADHD medication Ritalin is a tablet that is released immediately into the bloodstream and works for four hours. Ritalin LA, on the other hand, is a capsule that releases over a longer period of time and works for eight hours. Different names, even though both contain the same medicine — methylphenidate.

How Do Stimulant Medications Treat ADHD?

ADHD is a neurologically based disorder, resulting from the deficiency of a neurotransmitter, or a group of neurotransmitters, in specific areas of the brain. Neurotransmitters are chemicals that transmit signals between nerve cells by bridging the synapse (or gap) between them.2

The key neurotransmitter involved is norepinephrine, along with its building blocks, dopa and dopamine. In theory, the primary medications used to treat ADHD stimulate specific cells within the brain to produce more of the deficient neurotransmitter. That’s why these medications are called stimulants — though it’s unknown exactly how they work to relieve ADHD symptoms.

The two main classes of stimulant medications, methylphenidate and dextro-amphetamine — both are generic names — have been used since the 1930s.3 All brand-name stimulants are variations of these two medications. The ADHD medication Adderall is a modification of dextro-amphetamine, for instance, while methylphenidate comes as an immediate-release tablet, a chewable tablet, a liquid, a skin patch, an intermediate-acting (extended-release) tablet, a long-acting (extended-release) capsule, and a long-acting (extended-release) tablet. Each variation has its own name, but the medicine that treats symptoms is the same — methylphenidate.

How is ADHD Medication Dosed?

Parents of children with ADHD ask me: “My child was on Adderall 10 mg, and my doctor changed her prescription to Vyvanse 60 mg. Why was the dose increased?” The reasons for the numbers have to do with target dose and release mechanism.

Target dose: Each product releases a specific amount of medication into the blood over a given period of time. The FDA requires that the number value for each product represent the total amount of the medication in the tablet/liquid/capsule/patch, not the amount in the blood at any one time. Thus, if the medication, let’s say methylphenidate, is in the form of a four-hour tablet, and it releases 5 mg over that time, it is called methylphenidate 5 mg. A capsule of Adderall that releases 10 mg immediately and 10 mg four hours later is called Adderall XR 20. The number is not based on the amount released at any one time, but on the total amount of the medication in the capsule.

Release mechanism: This indicates the length of time a medication will remain available and active. Stimulants come in a variety of forms — tablet, capsule, liquid, skin patch — and release medication in an hour, four hours, or over eight or 12 hours.

How Does Concerta Work? How Is It Different From Other ADHD Medications?

Many people are confused about the ADHD medication Concerta. Designed to last 12 hours, Concerta has a “sponge” on the bottom of the capsule, medication on top, and a tiny hole above the medication. As the capsule passes through the gastrointestinal tract and absorbs moisture, the sponge expands and pushes the medication out of the hole.

The number value assigned to each dose is confusing. Take Concerta 18 mg. If the goal is to release 5 mg consistently every four hours over a 12-hour period, then there needs to be 15 mg in the capsule. However, it takes time for the sponge to become moist enough to start to expand. So an initial release of medication is needed until the sponge starts working. Researchers figured out that it should be 3 mg. Thus, to release 5 mg over 12 hours, one needs the initial 3 mg, plus 5 mg every four hours during the 12 hours. The total amount of medication is 18 mg. That’s why the medication is called Concerta 18.

Same ADHD Medication, Different Formulations

Medications such as methylphenidate and dextro-amphetamine also come in liquid forms. The patient information sheet inside the medication’s box or packaging states how much medication is in each unit of liquid; for example, 5 mg per 5 ml of liquid. Another methylphenidate product — Daytrana4 — is a patch that releases medication through the skin and into the bloodstream. Daytrana 30 mg contains about 30 mg of methylphenidate, and releases about 3.3 mg of it per hour.

Which ADHD Medication is Best?

In short, there’s no way to know which stimulant medication will work “best” for any one person’s ADHD. It’s often related to your history, your genetics, and your or your child’s unique metabolism.

  1. Are there any studies that look at the long-term health effects of taking either methylphenidate or dextro-amphetamine for an extended period? Changes in aging stress hormones or metabolism?

  2. >>> I hope parents of children on ADHD stimulants read this, especially if they are punishing their child for stimulant-rebound meltdowns. <<<

    Vyvanse is “slow-on, slow-off,” with about a 2-hour ramp-up/ramp-down time. That means that you don’t get nearly the medication rebound that happens with other stimulants. Having experienced the rebound of short-acting stimulants myself, I am amazed that doctors still prescribe them. (It may be due to expense/insurance, but that needs to change.) Talk about “do no harm.” It is a horrible experience; you feel like dirt. (See below for a detailed description of my experience.) And it is happening to young kids who can’t describe their experience.

    I feel so sad for all the young kiddoes suffering daily rebounds, often at homework time, and the parents who are trying to manage the meltdowns.

    Vyvanse is the only medication that has been effective for my two daughters w/o significant side effects. I started taking it 3 years ago, and now both of my daughters as well as my sister do. She thanked me profusely for telling her about it – she had been taking Ritalin and didn’t like it so she had given up. She did have to go through a big rigmarole with her insurance, but they did approve it.

    I wish it had existed in 2014 when my younger daughter was diagnosed with ADHD at the end of 1st grade. Due to ineffectiveness and/or intolerable side effects of the medications we tried (several stimulants of each type, as well as each of the non-stimulant ADHD medications), we gave up on medication and she has gone untreated for nearly 4 years, poor thing (until just recently, when we tried Daytrana — ineffective, and now Vyvanse). However, she managed well (good grades, good behavior — but would fall apart after school) until this year – 5th grade was just more than she could handle untreated, and she was diagnosed with anxiety and depression.

    When we learned last year that my middle school daughter had stealth ADHD, I couldn’t believe that our then-psychiatrist gave her Ritalin with the instruction to go to the nurse’s office during her (very short) lunch. Needless to say, she didn’t go, and he wouldn’t prescribe Vyvanse. I figured it wasn’t used in kids.

    When we recently switched to a pediatric psychiatrist with a top-notch reputation, she prescribed Vyvanse for both girls without blinking an eye.

    I would say that Vyvanse has changed our lives. (I have no affiliation with any pharmaceutical company or anything else remotely related.)

    I hope my recounting of our experience helps someone else. Our lives would have been so much better had Vyvanse been available in 2012.


    Here’s an email I wrote to a parenting coach / child therapist who specializes in challenging children:

    “I now know how HORRIBLE [my daughter] felt during 1st grade, and thousands of other kids feel when they take short-, mid-acting stimulants and they wear off (right at homework time). It’s really rough and unlike any physical illness you might be familiar with. I felt sick, but not like a flu. Metaphorically, kind of like bad nausea if applied to the whole body and brain/mind. A state that a child’s brain really shouldn’t have to be in (but of course I recognize the need and advantage of stimulants) and that a child shouldn’t have to experience.

    “I wish I had a way to tell all the parents, so they could really sympathize with their children. I know that we found the horrible rebound behavior [my daughter] had, to be stressful for US, but didn’t REALLY get how horrible she must have felt.

    And her response:

    “Thanks for the info on the rebound.  I have witnessed and heard countless stories of the crash that occurs when kids’ meds wear off but didn’t know the chemical reason and so it is helpful to hear from an articulate adult on it so that I can share it with parens whose kids cannot explain it.”

  3. You left out #10 – Tenex (gunafacine) another non-stimulant medication

    #11 – clonidine another non-stimulant used as an alternative /add on med

    It would have been useful to include those in this article. Makes it out of date.

  4. My 12 year old son has been on various forms of stimulants for 6 years. His level of focus has barely improved. Worse, I am now far more concerned that his growing body is not getting the nutrition it needs during this critical part of his life. And this is something I know about. As an aside, my mother came from a poor farm family with 9 kids. With the exception of the two oldest, the other 7 were all put up for adoption. The youngest were all adopted immediately (at that time age 4 and under). The older children (age 7-14) took longer to adopt. The 3 youngest (boys) all grew up to be over 6′ tall. None of the others grew to be taller than 5’3. That was all due to diet and the availability of nutrition. Luckily my mother and a younger brother were the next to go and only had to wait a year to be adopted and both were adopted into families that were able to provide proper nutrition and educational support. The older 4 children were all dead by age 60. With the exception of one killed in military service, the younger ones (and her brother) have all lived to be over 85. So now here is my son, whose primary dosage has been Focilin and Focilin XR. He is 58″ tall which puts him on the smaller side (39th decile – normal). But he only weights 60 lbs putting him in 0.75 percentile for weight. His BMI is 12.5. That puts him so low on the BMI scale that it if anyone were to see him, you’d think he was anorexic. This is completely due to his medication. How able to focus will he be if his brain doesn’t get enough protein to form. These drugs are as much a part of the problem. Worse yet, they are only treating a symptom, not the root cause. He is also diagnosed with Aspergers. Against his physicians request and his mother’s, I have been able to get a court to allow him to be treated by a respected Children’s Hospital in our area on a new program that seeks to prove that the increases in spectrum disorders and ADHD are due to a microbiome imbalance. With any luck, he will be off these terrible prescriptions.

  5. Been on Vyvanse for 7 years and in the last year i have noticed some changes. It is making me mentally spiral and generally feel dysphoria. I have been taking instant release dex instead to avoid these negative side effects. i have discussed with a fellow adhd’er and she noticed a similar change at the same time i did. when i am on it I have no natural confidence despite being very confident the days i don’t take… it on these days i have zero focus. Any theorys/ suggestions?

    i feel like the formula has changed honestly
