Provider Briefing: The Amphetamine XR Shortage in 2026

The ongoing shortage of amphetamine-based ADHD medications continues to create significant challenges for providers and their patients. Extended-release amphetamine formulations — including Dyanavel XR, Adzenys XR-ODT, and Adzenys ER — remain particularly difficult for patients to obtain due to their brand-only status and single-manufacturer supply chain.

This article provides an updated clinical overview of the shortage landscape, its implications for prescribing, and practical tools to help your patients maintain treatment continuity.

Shortage Timeline

The ADHD stimulant shortage began in October 2022, initially centered on Adderall (mixed amphetamine salts) and quickly expanding to affect most amphetamine-based products. Key milestones:

  • October 2022: FDA formally acknowledges shortage of amphetamine mixed salts (Adderall)
  • 2023: Shortage broadens to include extended-release formulations and lisdexamfetamine products
  • 2024: Supply improves modestly but remains constrained; generic Vyvanse (lisdexamfetamine) enters market
  • October 2025: DEA raises aggregate production quotas for d-amphetamine, methylphenidate, and lisdexamfetamine by up to 25%
  • January 2026: DEA finalizes 2026 production quotas via Federal Register notice
  • Early 2026: Supply remains below demand; brand-only products like Dyanavel XR and Adzenys XR-ODT continue to have intermittent availability

Prescribing Implications

The shortage creates several practical challenges in clinical practice:

Medication Switching

When a patient's preferred formulation is unavailable, providers must consider therapeutic alternatives. Key conversion considerations for Amphetamine XR:

  • Dyanavel XR to Adderall XR: Not a 1:1 mg conversion. Dyanavel XR contains amphetamine base, while Adderall XR contains mixed amphetamine salts (75% dextroamphetamine salts, 25% levoamphetamine salts). Dose adjustments are required.
  • Adzenys XR-ODT to Adderall XR: Similarly, these are not interchangeable on a mg-for-mg basis due to different salt forms and release mechanisms.
  • Switching to Vyvanse: Lisdexamfetamine is a prodrug of dextroamphetamine. Conversion tables are available but individualized titration is recommended.
  • Switching to methylphenidate: A different stimulant class entirely. There is no direct dose equivalence — start at a low dose and titrate based on response.

Prior Authorization Burden

Brand-name Amphetamine XR products frequently require prior authorization and may be subject to step therapy requirements (i.e., trial and failure of generic alternatives first). The shortage has made this process more burdensome, as patients may need multiple PA attempts across different medications.

Consider documenting shortage-related medication changes clearly in patient records to support PA appeals.

Controlled Substance Prescribing Constraints

Schedule II prescriptions cannot be called in to pharmacies in most states and generally cannot be transferred. This means patients who find stock at a different pharmacy may need a new prescription sent electronically. Streamlining your e-prescribing workflow can reduce delays.

Current Availability Picture

As of early 2026:

  • Dyanavel XR (Tris Pharma): Intermittently available. Single manufacturer; supply dependent on Tris Pharma production capacity and distribution.
  • Adzenys XR-ODT (Tris Pharma): Similar intermittent availability. No generic equivalent.
  • Generic Adderall XR (mixed amphetamine salts XR): More broadly available due to multiple generic manufacturers, but still subject to regional shortages.
  • Generic Vyvanse (lisdexamfetamine): Availability improving since generic launch in 2023, though some supply constraints persist.

Cost and Access Considerations

Cost remains a significant barrier for brand-name Amphetamine XR formulations:

  • Dyanavel XR: $440–$590/month cash price
  • Adzenys XR-ODT: $330–$735/month cash price
  • Generic Adderall XR: $17–$50/month with discount coupon
  • Generic Vyvanse: $30–$70/month with discount coupon

The Tris Pharma Savings Card (coupon.trisadhd.com) offers commercially insured patients a copay as low as $20. Cash-paying patients may qualify for reduced pricing on their first fill.

For patients with financial hardship, resources like NeedyMeds.org and RxAssist.org can help identify patient assistance options. See our provider's guide to helping patients save money on Amphetamine XR.

Tools and Resources for Your Practice

Medfinder for Providers

Medfinder offers a provider-facing tool that helps you and your patients identify pharmacies with current stock of Amphetamine XR. Recommend it as part of your standard discharge or prescription workflow during the shortage.

Patient Education Materials

Direct patients to these resources:

Proactive Prescribing Strategies

  1. Prescribe generics when clinically appropriate — generic Adderall XR and generic Vyvanse have broader supply and lower cost
  2. Include "DAW 0" or permit substitution to maximize pharmacy flexibility
  3. Provide backup prescriptions — if switching is needed, having a second prescription ready can reduce delays
  4. Document shortage-related changes for PA appeals and treatment continuity

Looking Ahead

The DEA's increased 2026 production quotas should gradually improve supply, but the gap between production capacity and demand is unlikely to close quickly. Providers should plan for continued intermittent availability of brand-name Amphetamine XR products through at least mid-2026.

Key developments to watch:

  • Whether Tris Pharma scales production to meet quota increases
  • Any new generic approvals for Dyanavel XR or Adzenys XR-ODT formulations
  • Federal policy changes regarding telehealth prescribing of controlled substances

Final Thoughts

Managing ADHD treatment during an extended medication shortage requires flexibility, proactive communication, and awareness of the full range of available options. By staying current on the supply landscape and using tools like Medfinder for Providers, you can help your patients maintain treatment continuity even when their preferred formulation is hard to find.

Can I convert Dyanavel XR to Adderall XR on a mg-for-mg basis?

No. Dyanavel XR contains amphetamine base, while Adderall XR contains mixed amphetamine salts. The bioavailability and potency differ between formulations. Consult conversion guidelines and titrate based on individual patient response.

What should I document when switching patients due to the shortage?

Document the reason for the switch (medication unavailability due to shortage), the prior medication and dose, the new medication and rationale for the chosen dose, and any prior authorization requirements. This supports continuity of care and PA appeals.

Are there any new generic alternatives expected for Dyanavel XR?

As of early 2026, no generic version of Dyanavel XR has been approved. Patent expiry timelines suggest potential generic entry may occur around 2026-2027, but no firm dates have been announced by the FDA.

How can I help patients who can't afford brand-name Amphetamine XR?

Recommend the Tris Pharma Savings Card (copay as low as $20 for insured patients), discount platforms like GoodRx or SingleCare, and patient assistance resources at NeedyMeds.org. When clinically appropriate, switching to generic Adderall XR ($17–$50/month) or generic Vyvanse ($30–$70/month) can dramatically reduce costs.
