How does Adderall work?

Adderall is a prescription drug that’s used to treat ADHD and narcolepsy.  Adderall shows up in urine tests as an amphetamine up to four (4) days after a single dose and up to a week or longer after chronic use.

But how exactly does Adderall affect the body and brain? Does it have the same effects for everyone? Although Adderall peaks in 1-2 hours after you take it, can you make Adderall effects last longer or work better? We’ll explore these questions and more in this article. And we invite your questions about how Adderall works at the end.

How does Adderall work in the body?

In general, Adderall or amphetamine salts work in the body by affecting the brain and nervous system. Adderall can also have unpleasant, and sometimes dangerous, side effects. Most commonly, this includes stomach pain or headache. But even at normal doses Adderall can sometimes cause more serious adverse effects, including shortness of breath, seizures, heart problems, hallucinations, or changes in behavior. There’s no way to predict who will experience these adverse effects, but they’re more likely to occur when Adderall is taken in a way other than directed by a doctor. But in general, how much Adderall is safe is up to 40 mg per day for children, and 60 mg per day for adults, more or less dosage depending upon physical tolerance to amphetamines.

How does Adderall affect the brain and nervous system?

The aphetamine salts found in Adderall are central nervous system stimulants. At its most basic level, Adderall works by increasing the amount of dopamine and norepinephrine in the brain. This is why people who use Adderall for non medical reasons may experience euphoric effect. And pursuing an Adderall high can get you addicted to amphetamines.

But therapuetic use of Adderall rarely develops into addiction. Adderall works in people with excessive sleepiness (narcolepsy) by stimulating the central nervous system. In people with ADHD, it has a paradoxical effect, helping them focus and remain calm. People using Adderall to treat ADHD won’t get “high” from their medication. Adderall’s stimulant qualities can affect the brain and nervous system and result in:

  • difficulty with sleep
  • nervousness
  • restlessness

How fast does Adderall work

Adderall reaches its peak level in the blood in 1-2 hours. At that point, Adderall has taken full effect. Sometimes people will crush and snort the powder from the tablets to try to get more immediate effects. Although possible, this practice is very dangerous. Snorting Adderall can result in increased adverse effects, overdose, or even sudden death.

How long does Adderall work?

Adderall stays in the body for several days, with a half life averaging around 10-11 hours. The extended-release formula will remain effective throughout the day, while the immediate release may need to be taken more frequently and is prescribed two or more times daily.

What makes Adderall work better?

Adderall works best when it’s taken exactly as prescribed by your doctor. Taking Adderall only when you feel you “need” it can actually make the medication less effective. Taking Adderall with large amounts of vitamin C may also lessen the effects of Adderall. However, Adderall can be taken on an empty stomach to get the best effect.  And contrary to popular belief, mixing alcohol with Adderall does not enhance Adderall effects.  Instead, drinking while on Adderall increases your risk of alcohol poisoning and related accidents or death.

Does Adderall work for everyone?

No, Adderall is not right for everyone. Amphetamine salts shouldn’t be prescribed to anyone who doesn’t need it for a legitimate medical purpose due to the risks of side effects, including possible Adderall addiction. Adderall is addictive and should be avoided by people with a history of addiction. And in some people, Adderall can trigger serious side effects, particularly people with a history of seizures or cardiovascular conditions.

“Adderall is addictive and should be avoided by people with a history of addiction.” Does this mean anyone who is addicted to any drug, or only individuals addicted to amphetamines?

Hi Matthew. Great question, thanks. Adderall is prescribed with caution to anyone with a personal or family history of ANY drug, alcohol or substance addiction. Adderall can cause euphoria, and there is a higher risk of developing an amphetamine addiction in these populations than in people with no prior history of substance abuse.

How dangerous is it to take a low dose say 10-15mg with no previous conditions for study purposes?

1:00 am August 1st, 2012

Hi Annonomous. While it may not be too dangerous to take a low dose of Adderall, it is ILLEGAL. If you are caught taking someone else’s prescription, you can be jailed. Also, Adderall has been known to cause adverse side effects such as heart palpitations, dry mouth, rashes or impotence. Sudden death has also been reported on Adderall, although these cases are rare. We DO NOT RECOMMEND taking Adderall to study…the enhanced focus and concentration can compel you to use Adderall more often, and even become addicted to it. Did we answer your question?

When comparing a 20 and 30mg Adderall IR, does the 30 last longer or have stronger effects? Or both? Thanks!

Hi Matt. Thanks for your question. It seems to be both. Effects of stimulants are dose-dependent and higher doses can lead to better therapeutic responses, depending on medical use. Furthermore, the time of peak effects and the duration of action can increase with increased doses of Adderall. You can read more by searching for “site:.gov adderall dose length of action” in your internet browser.

I have been prescribed Adderall IR 10mg twice per day. Is this a medication that has to be taken on a regular basis in order to be effective? And how long before I notice any benefit from the medication?

Hi Janet. This is a question best fielded by your prescribing doctor or a pharmacist. Please let us know if need additional help.

Hi, I was formally diagnosed with narcolepsy in 2005, tried provigil and nuvigil on and off for years, new doctor just prescribed adderrall 20mg 2x per day. I am very nervous about taking it, have tried it 2x so far and gave me bad insomnia which is horrible for someone already sleepy. Should I be nervous about taking it? Has it been shown to be beneficial in treating excessive daytime sleepiness? Thanks

Hi Jeff. Adderall can work for some people to treat daytime fatigue. But if you find yourself wired, note the symptoms, the time and dosage of Adderall and report them to your prescribing doctor. It’s possible that amphetamines are not right for you.

My wife takes Adderall for ADHD and she tells me that if were to take it it acts like speed. Well that may be true what I need answered is will Adderall not only help her excutive funtions but in some way act like speed to her? Will it keep her awake or perk her up after she takes it. Because it is an Amphetamine not only does it add dopemine to her brain but will stimilate her heart and body??? thank you

10:07 am September 27th, 2013

Hello Glen. Thanks for your question. Adderall affects each person differently. She’ll have to give it a try (at the lowest therapeutic dose possible), record the side effects and report back to her prescribing doctor for adjustments, when needed. But it’s really quite impossible to predict the outcome of an ADHD medication until you start it.

My doctor switched me from Vyvanse 40MG to Adderall IR 20MG.
The Adderall doesn’t feel like the Vyvanse at all, although they both are Amphetamines.
Question time: Vyvanse works by turning on your body’s Fight or Flight Response. Does adderall do the same thing, or is it doing something different, because like i said before, It doesn’t feel like the Vyvanse did.

I was prescribed adder all for years for excessive day time sleepyness and it worked great for me. I was able to stay awake and get my daily tasks done no problem and actually got my daily activities done quicker then normal but I had noticed I was becoming dependent to it also after about a couple of months my doctor would have to up the dosage because I was getting used to it. I have quit taking it since then because I didn’t want to form a full on addiction to it. I took it for about 3-4 years been off it for about 3, 3 1/2, 4 years and have learned to work through my day without it. Also had to stop taking it because the perscription is expensive and I don’t have insurance to help cover it. I was taking 50mg once a day.
