How Long Does Adderall Last? Duration Based on Dosage

Used to treat ADHD and narcolepsy, Adderall helps improve focus, attention, and impulse control. The duration of its effects depends on the dosage and form of the medication. Adderall comes in different doses and two main types: IR (immediate-release) and XR (extended-release).

Immediate-release Adderall usually works for about 4 to 6 hours per dose. Extended-release Adderall is designed to last longer, typically around 12 hours. The exact time Adderall remains in the system can differ based on several factors, including your metabolism, body composition, age, and overall health.

How Long Does 5mg Adderall Stay In Your System?

A 5mg dose of immediate-release Adderall is often used for those starting treatment or for children. This small dose generally lasts for about 4 to 6 hours. However, Adderall can be detected in the system for longer.

  • Urine: Up to 3 days
  • Blood: Up to 46 hours
  • Saliva: Up to 48 hours

How Long Does 10mg Adderall Stay In Your System?

10mg of immediate-release Adderall is a moderate dose, typically lasting 6 to 8 hours. 10mg of the drug can stay in the system for the following durations:

  • Saliva: Up to 48 hours
  • Hair: Up to 3 months

How Long Does Adderall XR Stay In Your System?

Adderall XR is an extended-release form of the medication, designed to last around 12 hours. Because of its extended-release nature, Adderall XR stays in the system longer than the immediate-release form:

  • Urine: Up to 5 days
  • Blood: Up to 72 hours
  • Saliva: Up to 72 hours
  • Hair: Up to 3 months

Duration of Adderall in Urine, Hair, & Blood

How Long Does Adderall Stay In Your Blood?

Blood tests are less common but can detect Adderall use more quickly after ingestion. Adderall is detectable in the blood for up to 46 hours. Blood tests are more invasive but are useful for detecting recent drug use.

How Long Does Adderall Stay In Your Hair?
