Can't fill your Amphetamine/Dextroamphetamine XR prescription? Here are real alternatives your doctor may recommend, including Vyvanse, Concerta, and more.
If you've been trying to fill your Amphetamine/Dextroamphetamine XR prescription and keep running into empty shelves, you're dealing with a problem that has affected millions of patients since the shortage began in 2022. While the supply is improving in 2026, many patients still can't reliably find their usual medication.
The good news: there are several effective alternatives. Switching medications isn't ideal, but going without treatment is worse. In this guide, we'll explain what Amphetamine/Dextroamphetamine XR does, how it works, and which alternatives your doctor might recommend.
Important: Never switch medications on your own. Always talk to your prescriber before making any changes to your ADHD treatment.
Amphetamine/Dextroamphetamine XR is the generic version of Adderall XR, an extended-release stimulant prescribed for ADHD. It contains a mixture of four amphetamine salts that work in two phases: about half the dose releases immediately, and the other half releases about four hours later. This provides symptom relief for up to 12 hours from a single morning dose.
It's available in capsule strengths of 5 mg, 10 mg, 15 mg, 20 mg, 25 mg, and 30 mg, and it's classified as a DEA Schedule II controlled substance.
Amphetamine/Dextroamphetamine XR works by increasing the levels of dopamine and norepinephrine in the brain. These neurotransmitters play key roles in attention, focus, and impulse control. By blocking their reuptake and promoting their release, the medication helps improve concentration and reduce hyperactive or impulsive behavior in people with ADHD.
For a more detailed explanation, see our post on how Amphetamine/Dextroamphetamine XR works.
Vyvanse is one of the most commonly recommended alternatives. It's a prodrug, meaning it's inactive until your body converts it into dextroamphetamine after you swallow it. This design provides a smooth, long-lasting effect (up to 14 hours) and has a lower potential for misuse compared to traditional amphetamine formulations.
Vyvanse treats both ADHD and binge eating disorder in adults.
Concerta uses a different stimulant — methylphenidate — rather than amphetamine. It works through a similar mechanism (increasing dopamine and norepinephrine) but has a different chemical structure. Some patients who don't respond well to amphetamines do better on methylphenidate, and vice versa.
Mydayis contains the same amphetamine salts as Adderall XR but uses a triple-bead technology that provides coverage for up to 16 hours — longer than Adderall XR's 12-hour duration. It was designed for patients who need symptom control into the evening hours.
Dexedrine Spansules contain pure dextroamphetamine in an extended-release capsule. Since Amphetamine/Dextroamphetamine XR already contains about 75% dextroamphetamine, the transition can be relatively straightforward for many patients.
