How Long Does Adderall Stay in Your System- Urine, Blood, Hair, Saliva

Adderall is the brand name of a prescription drug used to treat children and adults.

Adderall is a combination of two stimulants, amphetamine and dextroamphetamine. Adderall XR is an extended form of the drug.

The drug can prevent narcolepsy symptoms, which include excessive drowsiness and sudden bouts of daytime sleepiness.

It is widely prescribed for medical purposes, in child psychiatry, for attention deficit hyperactivity disorder (ADHD).

The active ingredient in Adderall is called amphetamine.

Amphetamines (commonly known to junkies such as speed, Self, Billy, crystal, and whiz) are non-catecholamine sympathomimetic drugs that stimulate the central nervous system and produce cortical excitability.

The mechanism of action of amphetamine contained in Adderall works by enhancing the action of neurotransmitters in the brain such as adrenaline, dopamine, and norepinephrine.

These neurotransmitters are stimulants in nature, which means that they help in situations of stress, such as the need to fight or escape.

Amphetamine has similar pharmacological effects observed in cocaine users. However, Adderall produces results that are long-acting than those found in cocaine users and is therefore commonly abused.

How Long Does Adderall Stay in Your System- Urine, Blood, Hair, Saliva

Depending on the type of Adderall and how your body metabolizes medications, this medication can stay in your body for several hours to days or months.

Whether or not the drug is detected in your system will also depend on the type of test used to measure the level of the Adderall.

Types of Adderall

Types of Adderall There are two types of Adderall on the market: regular (immediate release) and XR (extended release). Drug levels are measured in “half-life.” The half-life of a drug is the amount of time it takes for half of the drug to be excreted by the body.

A good rule of thumb: You can do a calculation pretty close to how long it will take for a drug to be ultimately out of your system by multiplying the half-life of the drug by 6.

So, in the example of a half -10 hours life, it would take about 60 hours (10×6) for all drugs excreted from the system. Of course, this will also depend on the ability of the individual to metabolize the drug.

Adderall regular release has a half-life of 4-6 hours. Using our formula, we can quickly estimate that all drugs can be gone within 24-36 hours.

Adderall extended release has a half-life of about 10-13 hours. By using the formula one more time, this means that this formulation of the drug can last in your system for 60-78 hours.

All of this should be considered as an approximation since individuals will treat drugs differently.

Test types

How Long Does Adderall Stay in Your System- Urine, Blood, Hair, Saliva

Whether or not and how long Adderall can be detected in your system is directly related to the kind of test used for the measurement.

Urine test. Urine tests are a very common way to test drugs in your system. Adderall can usually be detected in a urine test for 1-4 days after stopping the use of the drug. If you have used the drug for an extended period, Adderall can be detected in the urine for a week.

Blood test. Because blood is purified very regularly in the body, Adderall is usually found only in the blood for about 12-24 hours. This type of test is typically used to manage a patient who has been prescribed the medication for a health reason. The doctor can monitor Adderall’s blood levels to ensure that the dose is correct for the patient.

Salivary test. Testing for Adderall using your saliva is a convenient alternative to urine tests. The accuracy of this test is about the same as for urine tests, but it has not gained widespread acceptance as it has not been approved by the FDA.

Hair test. Hair tests for Adderall are less frequently used as it is a relatively expensive test that can cost $ 100-200. In this test, the tester will try to get a lock of hair that is cut as close as possible to the scalp. Each attempt to get the most recent hair growth that would be next to the scalp. Using this method, it is possible to determine how long ago Adderall was used. The presence of Adderall in the hair can be tested for up to 3 months.

How long does the Adderall XR last?

For me, it depends on what dosage you take. As I take 25 mg XR, if I do not drink any fluids, it just stays in my system longer. It lasts about 8-12 hours. I would not recommend not to use liquids for 8-12 hours. 

All amphetamines are ready to dehydrate you, therefore, without drinking any liquid, you can dehydrate.

I guarantee that a person feels like shit at the end of the day and almost goes away every time he gets up, especially if they don’t eat. Be sure to drink plenty of fluids and eat even if you don’t want to. It will work wonders if you experience a “wreck” or “hangover” in the morning.

How Can Adderall be Taken?

Adderall is consumed by snorting, injection, smoking and orally, by ingestion. To determine how long the Adderall will stay in your system, you have to decide which type of Adderall was taken. The two kinds of being a slow or regular release.

The slow release persists for a much longer time in the bloodstream and, therefore, has a longer detection time, which means that it can be detected several hours to days after taking the last dose.

In contrast, a regular release has a faster elimination time, which means that it is eliminated from the body much faster and therefore the detection time is shorter.

This implies that it can be detected in a few hours from the moment of ingesting the last dose.

Some variables determine how long the Adderall will stay in your system. These variations may depend on some factors such as body weight, height, age, kidney/kidney function, dosage, hydration status, dietary intake, and urinary pH.

The difference between these variables in different individuals is what is manifested as the differences in the rates of excretion of the same dose of a drug in two different people.

For example, a young person and an older adult will have different rates of Adderall excretion because age is a variable that determines how quickly the drug is eliminated from the body.

Eliminate the Adderall Routes From the Body

Excretion is the process by which toxins and other substances leave the body through the excretory organs.

These excretory organs include the kidneys and the sweat glands, which eliminate toxins through urine and sweat respectively.

Adderall is eliminated from the body through urine, saliva, and hair. Traces of the drug are also detectable in breast milk and fetal circulation. The most reliable routes of excretion for the detection of Adderall are through urine, saliva, and blood.

The kidneys are responsible for the elimination of the drug through the urine. The urinary excretion of Adderall and other amphetamines is one of the most reliable methods of detecting the drug in the system.

The active form of Adderall, amphetamine, can be detected from urine with a standard cut-off of 1000 ng / mL.

Adderall is detectable in the urine within 4 to 6 hours after ingestion of the drug.

This earlier detection of the drug corresponds to the half-life of Adderall, which means that 50% of them can be detected within 6 hours after ingestion.

However, it takes several more hours for the medication to entirely leave the body.

Adderall excretion of saliva can be detected up to 72 hours from the time of taking the last dose. This means that the Adderall may appear on a saliva drug test even though the last dose was taken 3 days ago.

Adderall hair excretion may be detectable even after 3 months from the last dose. The hair test is ideal to determine how long ago someone took the last Adderall.

The metabolites of Adderall can also be detected in the blood. These amphetamine metabolites can be used to detect the Adderall that is circulating effectively in the system before it is excreted by the kidneys.

The long-acting Adderall has a longer elimination time compared to the normal type.

Drug Tests For the Detection of Adderall

Several drug tests are available for the detection of Adderall’s body. The tests used to detect the drug use different markers that are capable of detecting the presence of amphetamines in body fluids such as urine, saliva, and blood.

The hair test is rare. However, it is the most powerful with the detection time of a duration of up to 3 months. The urine drug test is the most common method used to detect Adderall.

It can provide accurate results, which recognize the drug up to 4 days of cessation of use. However, it can even be detected 7 days after the last dose in cases of renal failure or when a higher dose of the drug was ingested.

The blood test for the drug is used to test the Adderall metabolites that may still be circulating in the body.

This test can also be used in case of doubt, when a urinalysis was used, with suspicion of the inhibition of urinary elimination by use of the alkaline diet. The drug can be detected for a maximum of 46 hours after ingestion of the 10 mg dose.

The hair drug test is expensive and therefore is not a general purpose drug test method for Adderall. However, it gives extremely reliable test results, with a detection period of up to 3 months.

The results of the drug tests are not altered by the use of hair chemicals such as hair dyes because the detection markers use the hair follicle structural content. The hair drug test is a more reliable indicator of when the drug was taken last.

Adderall Clearance of the System

The clearance of Adderall from the system depends on whether the slow release or regular release tablet is ingested.

The regular Adderall has a half-life of 4 to 6 hours, and the drug can be completely eliminated from the system within 36 hours of the last dose is ingested. The half-life depends on the pH of the urine, the diet, the frequency of hydration and the dose.

Amphetamines are excreted efficiently through urine in normal renal function and can be detected from urine within 4 to 6 hours. It has a detection period of 2-4 days in the urine but could be longer than, depending on the dose.

The standard cut-off point for the urine drug test for Adderall is 1000 ng / mL. The clearance of Adderall through saliva is very rapid, and it has been reported that it is detected in the saliva within 5 to 10 minutes after use and can remain in the system for up to 3 days.

Amphetamines have also shown that their clearance is more efficient when the blood is more acidic, hence the recommendation that an acid diet after Adderall intake will contribute to its elimination from the system.

Generally, vitamin C is an excellent means of acidifying urine and is ideal for use in the elimination of residual amphetamines. In contrast, foods that are more alkaline tend to slow down the elimination and cleaning of amphetamines from the system, thus prolonging the Adderall elimination period.

Regular Adderall clearance is much faster because the half-life is shorter, at 4 to 6 hours, which implies that it takes 24 to 36 hours for the drug to be removed entirely from the system.

The Adderall slow release has an elimination half-life of 10 to 13 hours, which implies that it takes 60 to 80 hours for the drug to be eliminated from the body.

There are different reports on the time it takes for the drug to be voided from the system. These differences can be attributed to the variations in the factors that influence the excretion of a drug from the body.

These factors may vary among individuals, or they may vary in the same individual at different intervals, depending on whether the variables have a negative or positive effect on the clearance rate of the drug.

Thus, a standard can never be configured for the exact period when the Adderall is expected to be removed from the system. However, the deadlines given are approximations of the elimination rates that have been observed in different individuals who have the same or different doses of the drug.

Factors that Influence the Removal of Adderall From the Body

Factors that affect and influence Adderall elimination from the body include age, kidney function, body weight, urinary pH, and dose. Generally, a person with a higher body mass will erase the Adderall much faster than a thin person.

Younger people tend to have an efficient functioning of the kidneys, which means that the clearance of the drug from urine is much faster in young people of old age, due to decreased renal function.

In kidney disease states, the renal clearance of the drug is affected, which means that the elimination is slow.

The more acidic the pH of the kidneys, the faster the renal clearance, therefore, A diet rich in vitamin C and acidic foods such as lemons means that the drug is eliminated at a more rapid rate than when taking a diet rich in alkaline foods. At normal urinary pH, approximately 30% of Adderall is excreted unchanged.

The Detoxification of Adderall

Detoxification of Adderall depends on the type of Adderall being used, the two types being prolonged release and controlled release. Prolonged or slow-release tablets take longer to release and are removed more slowly, up to 72 hours.

The controlled-release tablets take 60 hours to be eliminated from the body through the bloodstream. The type of regular release takes 36 hours to be entirely excreted.

The detoxification of amphetamines causes withdrawal symptoms such as anxiety and palpitations. However, these withdrawal symptoms usually disappear after a week.

Home remedies for withdrawal include the use of vitamin C that contains foods such as oranges, lemons, and cranberries. These foods acidify the urine and therefore increase the rate of excretion of the kidneys.

The drugs used in the detoxification of amphetamines include benzodiazepines. These drugs have sedative effects and will help in calming the patient down from the hyperactivity associated with withdrawal symptoms.

Generally, abstinence symptoms in amphetamine abuse are well tolerated unlike other abuse of stimulants such as cocaine. Withdrawal symptoms persist for about a week, but maybe longer, depending on the strength of the last dose.

Tell your doctor if you have had any:

• Reactions to other stimulants
• Heart problems, high blood pressure or stroke
• Mental problems
• Problems with drug or alcohol use
• Tourette’s syndrome or any sudden, uncontrolled movements
• Attacks
• Liver disease
• Kidney disease
• Eye problems

If your child is taking Adderall, you should talk to your doctor about the risk of stunting.
Some stimulants can slow growth and development in children. The doctor will need to check your child regularly while the child is taking Adderall.

It is also important to confirm the diagnosis of ADHD before applying to appoint a child Adderall.

Sometimes poor school behavior or behavioral problems are symptoms of other problems that require treatment, such as dyslexia or mental illness. Medical experts don’t know if Adderall is safe for the elderly.

If you are over 65, ask your doctor if there are other drug options that might be safer for you.

Termination of Adderall reception

If you suddenly stop taking Adderall, you may experience withdrawal symptoms. Withdrawal symptoms may include depression or other sleep disorders, irritability and severe fatigue. You are at increased risk of getting used to the drug if you have abused drugs or alcohol in the past.

Adderall and pregnancy

Adderall may be unsafe during pregnancy. Because of this, talk to your doctor before you start taking Adderall. Call your doctor right away if you get pregnant while taking Adderall.

Also, do not take Adderall while breastfeeding because the drug may be passed through breast milk to the baby.

  • Adderall can also slow the child’s growth
  • Babies born to mothers addicted to Adderall may be born prematurely, low birth weight suffer, and may also suffer from withdrawal symptoms
  • Adderall passes through breast milk and may affect your baby, so breastfeeding is not recommended to take Adderall, while

Adderall Dosage

The doses of Adderall are individualized, so your dose will depend on why you are taking Adderall and on the body’s response to the drug.

Doctors usually start with a low dose and gradually increase it.

A child over 5 years of age who takes Adderallot ADHD usually starts taking 5 mg and gradually increases to 30 mg.

A typical dose for an adult with narcolepsy can begin with 5 mg and increase to 60 mg. You can take Adderall and Adderall XR with or while not food. People typically take Adderall tablets each four to 6 hours throughout the day.

Adderall Overdose

Symptoms of overdose may include:

  • Strong anxiety
  • Aggression
  • Hallucinations
  • Hurried breathing
  • Fever
  • Pushes
  • Severe fatigue
  • Palpitation
  • Attacks
  • Loss of consciousness

Missed Adderall dose

Take Adderall exactly as directed by your doctor. Stop taking the drug gradually. Otherwise, it can cause severe depression, fatigue and other withdrawal symptoms.

If you miss a dose of Adderall, take it as soon as you remember. But if it’s time for the next dose, skip it. Do not double the dose to compensate for missing.


Adderall, like any other amphetamine derivative, is a central nervous system stimulant.

It is widely used in the form of prescription medication and is also widely used for recreational purposes, as well as improvements in performance. Its effect on the body is similar to adrenaline.

The dosage of Adderall can be either in the form of slow release or regular release. The elimination of the drug from the body depends on several factors such as weight, dose, urinary function, and age.

It is excreted mainly through the kidneys. Therefore, anything that improves the efficiency of the excretion of the kidney will directly influence the rate of excretion of the drug from the body.

On average, it takes 2 to 4 days for the regular release Adderall to be removed from the body, but it can take up to a week for slow release, after the last dose.

However, there is no clear clearance rate of the drug that can be applied to all individuals because different factors can affect different people in different ways and therefore differences in the rate of drug clearance are observed.

Several drug tests are used to detect the presence of Adderall in the body, with the urine drug test being the most common, as it is much cheaper and easier to administer.

There is no explicit clearance rate for the drug that can be applied to all individuals because different factors can affect different people in different ways and therefore differences in the clearance rate of the drug are observed.
