How long does Adderall stay in your system?

Adderall is the brand name for a type of drug that is often used to treat attention deficit hyperactivity disorder (ADHD). It is an amphetamine, which is a type of medicine that stimulates the central nervous system. How long does Adderall stay in your system?

According to the Cleveland Clinic, prescription stimulants like Adderall improve ADHD symptoms in 70 to 80 percent of children and 70 percent of adults.

Adderall can also be used for some sleep disorders, such as narcolepsy. It is used off-label for severe depression.

Adderall has a high potential for misuse. It can be used by people without a prescription to increase focus and concentration.

Read on to find out how long this drug stays in your system, as well as how it works and the possible side effects.

How fast does it get out of your system?

Adderall is absorbed through the gastrointestinal tract. It is then metabolized (broken down) by the liver and leaves the body through urine.

Although Adderall is excreted through urine, it works throughout the body, so it can be detected in a number of different ways, as described below.


can be detected by a blood test up to 46 hours after the last use. Blood tests can detect Adderall more quickly after it has been used.


Adderall can be detected in the urine for approximately 48 to 72 hours after the last use. This test will generally show a higher concentration of Adderall than other drug tests, because Adderall is excreted through urine.


Adderall can be detected in saliva 20-50 hours after the last use.


The hair drug test is not a common testing method, but it can detect Adderall for up to 3 months after the last use.

What can affect how long it stays in your body?

Different people's bodies metabolize, break down, and eliminate Adderall at different rates. The length of time that Adderall stays in your body before it is metabolized can be affected by a variety of different factors.

Body composition

Your body composition, including your total weight, the amount of body fat you have, and your height can affect how long Adderall lasts in your system. This is partly because older people generally need higher doses of medications, which means that the medications take longer to leave their bodies.

However, there is some evidence that after taking into account the dosage based on body weight, drugs such as Adderall, which are metabolized by a certain liver pathway, are eliminated from the body more quickly in people who weigh more or have more body fat.


They all have enzymes in the liver that metabolize or break down drugs like Adderall. Your metabolic rate can be affected by everything from your activity level to your gender and other medications you take.

Your metabolism affects how long a drug stays in your body; the faster it is metabolized, the faster it will leave your body.


Adderall is available in a variety of strengths, ranging from 5mg to 30mg tablets or capsules. The higher the dose of Adderall, the longer it will take for your body to fully metabolize it. Therefore, higher doses will stay in your body longer.

Adderall comes in immediate and extended-release versions that dissolve in the body at different rates. This can affect how long the medicine stays in your system.


As your age, it may take longer for medications to leave your system. This is due to several reasons.

  • The size of your liver decreases as you age, which means it may take longer for your liver to break down Adderall completely.
  • Urine production decreases with age. Kidney function can also decline as a result of age-related conditions, such as heart disease. Both of these factors can make the drugs stay in your body longer.
  • Your body composition changes as you age, which can lead to changes in how quickly your body breaks down and removes medications.

Organ function

Adderall is absorbed through the gastrointestinal tract, then it is metabolized by the liver and excreted by the kidneys. If any of these organs or systems are not working properly, Adderall may take longer to leave your body.

How does Adderall work?

It may seem counterintuitive, but Adderall works by stimulating the central nervous system.

People with ADHD are believed to not have enough dopamine in their frontal lobe, which is the "reward center" of the brain. Because of this, they may be prone to seek stimulation and the positive sensation that accompanies dopamine in the frontal lobe. This can cause them to engage in impulsive or thrill-seeking behavior, or become easily distracted.

By stimulating the central nervous system, Adderall increases the amount of dopamine available in the frontal lobe. This helps people with ADHD to stop seeking stimulation, which in turn helps them focus better.

Medication is usually just one part of an overall ADHD treatment plan, along with behavioral therapy, education and organizational support, and other lifestyle methods.

The Secondary Effects

Taking too much Adderall can cause mild and dangerous side effects, including:

headache hyperventilation dry mouth pounding or rapid heartbeat reduced appetite shortness of breath digestive problems numbness in the arms or legs difficulty sleeping seizures restlessness aggressive behavior dizziness mania changes in sexual desire paranoia anxiety or panic attacks

Also, your body can become dependent on Adderall if you take too much. When you try to stop using it, you can withdraw. In addition to craving Adderall, other withdrawal symptoms can include:

  • fatigue
  • agitation
  • depression
  • trouble sleeping, including insomnia or sleeping more than normal; you can also have vivid dreams
  • increased appetite
  • slow movements
  • slow heart rate

These symptoms can last up to 2 to 3 weeks.

Misuse of Adderall

Many amphetamines, including Adderall, have the potential to be misused. In some cases, people without a prescription may take Adderall to try to improve their focus or stay awake for long periods of time.

review of studies found that about 17 percent of college students reported the misuse of stimulants, including Adderall.

When Adderall is taken as intended, the effects of the drug can be positive. But for people without ADHD, who use the drug without medical supervision, the effects can be dangerous.

Even if you have a prescription, it is possible to misuse Adderall by taking too much or taking it in a way that was not prescribed.

The bottom line

Adderall can be detected in your system up to 72 hours, or 3 days, after your last use, depending on the type of screening test used.

The length of time that the drug stays in your system depends on many factors, including dose, metabolism rate, age, organ function, and other factors.

It is important to speak with your doctor or pharmacist if you have any questions or concerns about Adderall.
