Tag: Adderall duration

From 2012 to 2022, the number of stimulant prescriptions dispensed in the U.S. rose by nearly 58% [1.8.3]. A key question for many is: **how long does 20 mg Adderall last?** The answer depends primarily on whether the prescription is for immediate-release (IR) or extended-release (XR) [1.2.1].

Typically, the effects of an immediate-release Adderall tablet, often appearing as an orange pill, last for about 4 to 6 hours. This duration can be influenced by individual metabolism, dosage, and other health factors, making it a key consideration for those managing conditions like ADHD or narcolepsy.

According to research, the duration of Adderall’s effects is primarily determined by its formulation, with immediate-release (IR) lasting 4 to 6 hours and extended-release (XR) lasting 8 to 12 hours. Therefore, answering "how long does 15 mg Adderall last?" depends on which version is prescribed, alongside individual-specific variables that can alter its effectiveness.

According to a 2018 study reported by UCLA Health, the non-prescription use of Adderall among young adults rose significantly, highlighting widespread misuse. For someone without ADHD, the subjective effects and experience of Adderall differ substantially from a person with a clinical diagnosis.
