Adderall is frequently used to treat narcolepsy and attention deficit hyperactivity disorder (ADHD). It increases the brain’s dopamine levels, improves concentration, and lessens impulsive behavior. However, one inquiry that Adderall users frequently have is, “How long does Adderall last in your system?” This question’s response is dependent on several variables. To properly control their symptoms and prevent any adverse effects, people who take Adderall must be aware of how long the drug will last. Read on to learn the average duration Adderall stays in your body and the variables influencing its removal.

What is Adderalls half-life?

Adderall’s half-life varies, usually between 10 and 13 hours, but it may stay in your body longer. Because of this, it could take as much as two days for Adderall to leave your system altogether.

  • Immediate-release Adderall: The effects last 4-6 hours and are typically suggested to be taken 2-3 times daily. Once the drug’s effects have worn off, you can feel weary or irritated.
  • Extended-release Adderall: Its effects last approximately 10 to 12 hours and should only be used once daily. 

How long will Adderall remain in your system?

So, how long does adderall last? To detect Adderall in the body, various techniques might be used:


Adderall can be found in the urine for at least four days after the previous dose. Nevertheless, the detection period can change based on dosage, usage frequency, and individual metabolism.


Adderall can be detected in the blood until 46 hours after the last dose. The quickest technique to identify Adderall before it is cleared from the bloodstream is through blood tests.


Up until three months following your last dose, Adderall can still be found in hair. Hair tests are not routinely used to identify Adderall since they are expensive and typically take several days to produce findings.


Up to 20 to 50 hours after the last dose, Adderall traces may still be present in saliva. Saliva tests are rarely employed since they are less accurate at identifying Adderall than blood or urine tests.

Factors That Affect Adderall Elimination

The length of time Adderall remains in your body depends on the following factors:

  • Age: Compared to younger individuals, older individuals may have a slower metabolism of Adderall.
  • Weight: Heavier individuals may eliminate Adderall more quickly than lighter individuals.
  • Frequency of use: With continued use, Adderall can accumulate in the body, making it more challenging to eliminate.
  • The urine’s pH can affect how quickly Adderall is eliminated.


For individuals that require it, Adderall can be a beneficial drug, but it’s crucial to comprehend how long it stays in your system. The medicine’s effects may persist for many hours, but the drug itself may remain in your system for a long time. You should consult your doctor if you encounter any adverse reactions or are taking additional medications. They may be able to adjust your dosage or recommend a different medication to ensure that you get the treatment you need since the drug can be highly addictive. If you would like Adderall to leave your body more rapidly, you ought to drink a lot of water, exercise, consume a well-rounded diet, and rest.
