How Does Adderall Work? Understanding What This ADHD Medication Does to Your Brain

What Adderall Actually Does in Your Brain

Adderall is a stimulant prescription medication used to treat symptoms of attention deficit hyperactivity disorder (ADHD). So how does Adderall work? It works to boost the chemicals norepinephrine and dopamine in the brain, which helps increase focus, organization, attention, and impulse control for people with ADHD.

It's like turning down the volume on everything else except what you need to pay attention to, while turning that volume up on the one thing that matters. Like listening to an old FM radio between two stations, where you can sort of hear both but neither very clearly, Adderall turns the dial to focus on one station so you hear it loud and clear while the others fade into the background.

Adderall is a "tried-and-true" FDA-approved treatment for ADHD in both adults and children 6 and up and has been used for decades. It is a first-choice treatment for ADHD.

Let's explore dopamine and norepinephrine in more detail, clarify what a "stimulant" means, and discuss how Adderall works to treat ADHD so you can better understand its mechanisms of action.

The Brain Chemicals Adderall Affects

Dopamine and norepinephrine are chemicals in the brain that help you focus and stay motivated. Someone with ADHD has lower levels of these chemicals. Adderall blocks the reuptake of dopamine and norepinephrine, allowing the brain to have greater access to them. It accomplishes this by blocking dopamine transporters (DAT).

Dopamine is responsible for motivation, attention, focus, and impulse control, among other functions. Norepinephrine helps filter out distractions and keep you more alert. Norepinephrine also plays a pretty big role in your ability to focus.

Adderall can help reduce the tendency to wait for an approaching deadline before you can focus, as it increases norepinephrine levels. Similarly, because it can increase dopamine levels, you may find that you're more organized instead of always feeling scattered and behind.

Why It's Called a "Stimulant" (And What That Really Means)

Many people hear the word "stimulant" and wonder how that could calm them down, help them focus, and keep them organized. Adderall is a stimulant drug as it stimulates the CNS by boosting the two chemicals dopamine and norepinephrine. Because people with ADHD have lower levels of these two chemicals, Adderall increases their levels to keep improving focus and attention.

It stimulates chemicals in the brain, which does affect the central nervous system, but it is not designed to make you hyper. It is designed to boost those chemicals to normal levels so you can function with fewer symptoms.

People who use Adderall recreationally and not as prescribed are misusing the drug. If they do not have ADHD, they are "over-stimulating" these two brain chemicals, which can cause side effects like rapid heart rate, shaking, or other issues.

What Adderall Helps With (And What It Doesn't)

When looking at how Adderall works in the brain, it is important to note that it is not a cure for ADHD. However, Adderall can manage many ADHD symptoms, helping you live life with fewer unwanted side effects. It won't get rid of your ADHD altogether.

Just like when you break a leg, you can use tools like a cast or crutches to help you walk and function. Adderall is a tool that helps with your symptoms, but it won't alter your brain forever. Let's take a closer look at what Adderall can help with and what it can't.

The ADHD Symptoms Adderall Targets

Adderall does target some of the core ADHD symptoms, including attention span, impulse control, focus, organization skills, and hyperactivity.

Adderall could help you focus better at work, especially if you have long documents to read or you always find yourself looking out the window or scrolling on your phone. It may help when you are struggling to sit still, or help remove nervous energy that you can't seem to expel.

It may help reduce impulsive behaviors like shopping sprees or sending text messages on impulse. Adderall can also help with symptoms of executive functioning, including trouble with time management, memory, or misplacing items.

What Adderall Doesn't Do

There are many misconceptions surrounding Adderall and its potential uses. It cannot make you smarter or change your IQ. It has been known as a "study drug," mainly among college students, but studies show it doesn't enhance academic performance in people without ADHD.

It doesn't work the same way for people without ADHD as it does for people with ADHD. In fact, it becomes dangerous when people who do not have ADHD take stimulants, because their brain and central nervous system can become overstimulated.

Being overstimulated can cause anxiety, nervousness, insomnia, or even paranoia. These symptoms tend to make academic performance worse, not better. Studies suggest it caused more erratic thinking in those without ADHD.

How Long It Takes to Work and How Long It Lasts

When exploring how Adderall works, most people want to know how long it takes to start working and how long its effects will last. There are two formulations of Adderall: immediate-release and extended-release.

Immediate-release Adderall IR starts working right away and provides symptom relief for 4 to 6 hours. Adderall XR, the extended-release version, uses a beaded technology that allows the medication to be absorbed slowly, providing relief throughout the day for around 10 to 12 hours.

You will notice the medication wearing off when your ADHD symptoms worsen, and you may feel brain fog, irritability, or fatigue.

Immediate-Release vs. Extended-Release Versions

Let's go over the difference between Adderall XR vs IR.

Adderall IR is the immediate-release version, which provides 4 to 6 hours of symptom improvement and usually starts working within 30 minutes. It's often taken more than once a day for longer relief, and it's usually preferred by people who have issues with insomnia or simply want more control over their dosing.

Adderall XR is an extended-release version of amphetamine salts. It gives you 10 to 12 hours of symptom relief in a once-daily pill and usually starts working within 30 to 60 minutes. Adderall XR is often chosen when you want full-day relief but don't want to remember a midday dose.

Some people experience a "rebound effect," or crash feeling, as Adderall wears off. This rebound effect is usually more pronounced with the immediate-release version, since it tends to come on and leave the body more quickly than the extended-release version.

Common Effects People Experience When Taking Adderall

Let's take a closer look at some of the effects and improvements you may see from taking Adderall for ADHD, then go over some potential side effects. Everyone is different, so these are common effects, but your experience may vary.

The Positive Changes You Might Notice

You may notice benefits in focus and concentration fairly quickly. If you generally struggle with tasks that require a lot of focus, like schoolwork, paperwork, reading, or managing your bills, Adderall might make some of these tasks easier.

You may find you're able to follow through with tasks instead of hopping from one thing to the next. You may also notice reduced impulsivity and hyperactivity, such as less impulse buying or blurting things out, and better time management.

Not everyone responds to Adderall the same way, and you may not experience all of these benefits. If you're open with your provider, they may try you on an Adderall alternative that could work better for you.

Side Effects to Be Aware Of

Like any medication, Adderall has a few common side effects to be aware of. You may experience any of the following side effects when taking Adderall:

• Decreased appetite: Some people notice reduced hunger during the day.
• Difficulty sleeping: Falling or staying asleep can be harder, especially with later doses.
• Dry mouth: A common, usually mild, side effect.
• Increased heart rate: Your provider will monitor this over time.
• Headache: Often improves as your body adjusts to the medication.

Many of these side effects are temporary and may decrease as your body gets used to the medication. Work with your healthcare provider and let them know about any side effects you experience, and keep a journal if it helps you track how often they occur. If side effects don't improve after a few weeks, your provider may consider switching you to a different medication.

Why Finding the Right Dose Takes Time

ADHD medication, including Adderall, is not a one-size-fits-all treatment. Finding an ADHD medication that works specifically for you can take time and trial and error.

While your provider might start you on one medication like Adderall or Concerta, it's normal to try two or three before finding the one that works best for you.

The "best" ADHD medication is the one that provides the most symptom improvement with the fewest unwanted side effects. Be patient, and discuss any symptom changes and side effects with your provider at each appointment so you can find the right fit together.

Important Safety Considerations

Adderall is a stimulant medication and comes with a few important safety considerations. Some people may not be a good fit for Adderall, and there's also potential for misuse, so it's important to take it exactly as prescribed under the care of a licensed clinician.

Who Shouldn't Take Adderall

Adderall generally isn't recommended for people who:

• Have heart conditions or high blood pressure: Stimulants can increase heart rate and blood pressure.
• Have taken MAO inhibitors within the past 14 days: This combination can cause a dangerous interaction.
• Have a substance use disorder: Stimulants carry a higher risk of misuse for this group.
• Have glaucoma or bipolar disorder: These conditions require extra caution and monitoring.
• Are allergic to amphetamine or dextroamphetamine: An allergic reaction can be serious.

There are other medication combinations your provider will want to monitor, which is why it's so important to disclose every medical condition and medication, including supplements, that you take. Your provider needs the whole picture before making any medication decisions, and they'll monitor you regularly to ensure you're responding well.

Taking Adderall Safely and Responsibly

Adderall is a stimulant medication and a Schedule II controlled substance, so it carries the potential for misuse and physical dependence.

Taking Adderall as prescribed reduces your chances of developing a substance use disorder, though you can still develop physical dependence after long-term use. Never stop taking Adderall without speaking to your clinician first, since stopping abruptly after long-term use can cause withdrawal symptoms.

Never share your medication with others, even if you're both prescribed Adderall, because it's against the law and unsafe. Taking Adderall properly and under medical supervision can help you manage ADHD symptoms while reducing your risk of adverse effects.

Stimulant medications like Adderall are only available where a licensed clinician can legally prescribe them. On the ADHD Advisor platform, stimulant prescribing is currently available in 21 states, so eligibility depends on where you live.
