Dextroamphetamine xr (extended-release) is a central nervous system (CNS) stimulant used to treat Attention Deficit Hyperactivity Disorder (ADHD) in patients aged 6 and older, as well as narcolepsy. Originally sold under the brand name Dexedrine Spansule (now discontinued), dextroamphetamine xr is available as a generic extended-release capsule from manufacturers including Teva, Mallinckrodt, and Alvogen. The extended-release capsule releases medication gradually throughout the day, providing 8–12 hours of symptom control with a single morning dose.

Dextroamphetamine xr works by increasing the levels of two key neurotransmitters in the brain: dopamine and norepinephrine. It blocks the reuptake of these chemicals back into nerve cells and promotes their release into the spaces between neurons. This increased catecholamine activity in the brain helps improve focus, attention, and impulse control in patients with ADHD and reduces excessive daytime sleepiness in narcolepsy. The extended-release Spansule formulation uses a bead system to deliver medication in two phases — an initial dose upon ingestion and a delayed release several hours later.
5 mg extended-release capsule (Spansule) — capsule
10 mg extended-release capsule (Spansule) — capsule
15 mg extended-release capsule (Spansule) — capsule
Dextroamphetamine xr has a findability score of 35 out of 100, meaning it is frequently difficult to find in stock. The amphetamine shortage that began in October 2022 continues into 2026, with multiple manufacturers reporting back orders on extended-release capsule strengths — particularly 10 mg and 15 mg. Contributing factors include DEA production quotas, a surge in ADHD diagnoses during and after the COVID-19 pandemic, and limited manufacturing capacity. Patients often need to call multiple pharmacies to locate their prescribed strength. Medfinder can help you find dextroamphetamine xr in stock near you without the hassle of calling around.
