A significant percentage of ADHD patients rely on stimulant medications like dextroamphetamine to manage their symptoms, making the question of drug availability critical. When news of drug discontinuations or shortages arises, it can cause considerable anxiety. The story of Dexedrine and its availability is a prime example, with the situation often misunderstood due to manufacturer changes and broader supply chain issues impacting the market for controlled substances.
Brand-Name Dexedrine vs. Generic Dextroamphetamine
To understand the availability of this medication, it's crucial to distinguish between the original brand name, Dexedrine, and its generic equivalent, dextroamphetamine. While the brand name Dexedrine has existed since the 1930s, the current market is dominated by generic products and different brand formulations.
For example, while some brand-name Dexedrine Spansule extended-release capsules have been discontinued by their manufacturer, most doses of the generic extended-release capsules remain in production by other companies. The immediate-release version, dextroamphetamine sulfate tablets, is also available in generic form from multiple manufacturers. Another brand name, Zenzedi, also offers immediate-release dextroamphetamine tablets across various strengths.
Why Do Shortages Occur?
Shortages of ADHD stimulant medications, including dextroamphetamine, have been a recurring issue, leading many patients to question if a specific drug has been discontinued. These shortages are not due to safety concerns, but rather a complex set of factors affecting the entire market for controlled substances.
- DEA Quotas: The Drug Enforcement Administration (DEA) sets annual production quotas for controlled substances. Critics argue that these quotas can be restrictive and fail to keep up with increasing patient demand, leading to significant shortfalls in production. The DEA sets these caps almost two years in advance, making it difficult to adjust for real-time market shifts.
- Supply Chain Disruptions: Issues with the manufacturing and supply chain, exacerbated by factors like the COVID-19 pandemic, have created bottlenecks in the production and distribution of many medications.
- Increased Demand: The diagnosis and treatment of ADHD, particularly in adults, has increased significantly over recent years, putting additional pressure on the supply of available medications.
Available Dextroamphetamine Formulations
Patients prescribed dextroamphetamine have several options, though availability may vary based on manufacturer and pharmacy stock.
- Dextroamphetamine Extended-Release (ER) Capsules: Generic extended-release capsules are available in different strengths from various manufacturers like Mallinckrodt and Actavis Pharmaceuticals. It is these generic versions that patients often rely on when brand-name versions are unavailable.
- Dextroamphetamine Immediate-Release (IR) Tablets: Both generic and brand-name formulations are available. Brand name Zenzedi offers a range of doses, while multiple generic companies also produce the tablets.
- Dextroamphetamine Oral Solution: A liquid version, ProCentra, is also available, which can be a suitable alternative for patients who have difficulty swallowing pills.
- Dextroamphetamine Transdermal Patch: Xelstrym is a brand-name transdermal patch that delivers dextroamphetamine, offering a different delivery method for some patients.
Comparison of Dextroamphetamine Medications
Feature | Dexedrine Spansule (Brand) | Generic Dextroamphetamine ER | Zenzedi (Brand) | Xelstrym (Brand) |
---|---|---|---|---|
Active Ingredient | Dextroamphetamine Sulfate | Dextroamphetamine Sulfate | Dextroamphetamine Sulfate | Dextroamphetamine |
Formulation | Extended-Release Capsules | Extended-Release Capsules | Immediate-Release Tablets | Transdermal Patch |
Availability | Some strengths discontinued, others may be intermittently available | Generally available from multiple manufacturers, but subject to broader shortages | Available from Arbor Pharmaceuticals (Azurity) | Available from Noven Therapeutics |
Onset/Duration | 8-10 hours | Varies by manufacturer, generally similar to brand | Rapid onset, typically 4-6 hours | Smooth, steady release over 8-9 hours |
Usage | ADHD and narcolepsy | ADHD and narcolepsy | ADHD and narcolepsy | ADHD |
What to Do If You Can't Find Your Medication
If you encounter a shortage of your prescribed medication, it's important to take a proactive approach with your healthcare team.
- Communicate with Your Pharmacy: Ask your pharmacist if they have your medication in stock or if they can order it. They can also tell you which specific manufacturers they use, as generic formulations can vary.
- Contact Your Prescriber: If your pharmacy cannot fill your prescription, your doctor may be able to suggest an alternative. They might consider switching you to a different stimulant, a non-stimulant, or another formulation of dextroamphetamine.
- Explore Different Formulations: As noted, dextroamphetamine comes in different forms (capsules, tablets, patches, liquids). If one is unavailable, another may be in stock.
- Try Different Pharmacies: Availability can vary significantly from one pharmacy to another, even within the same chain.
- Consider Alternative Medications: For patients who do not tolerate or cannot find dextroamphetamine, alternatives such as methylphenidate-based drugs (Ritalin, Concerta), combination amphetamine salts (Adderall), or non-stimulants (Strattera, Qelbree) may be considered.
Conclusion
In short, the claim that Dexedrine has been discontinued is a simplification of a more complex situation. While brand-name Dexedrine Spansules have been partially discontinued, the active ingredient, dextroamphetamine, remains very much available through a variety of generic and other brand-name formulations. The primary challenge for patients is not a full discontinuation but rather the widespread and ongoing shortages of ADHD stimulants, which are driven by manufacturing constraints, supply chain issues, and DEA regulations. Patients experiencing difficulty in filling their prescriptions should maintain open communication with their healthcare providers and pharmacists to explore all available options, including alternative formulations and medications.

Understanding Dexedrine Availability
Specific doses of brand-name Dexedrine Spansule extended-release capsules have been discontinued by the manufacturer as of early 2024. Patients using discontinued doses will usually switch to a generic extended-release dextroamphetamine capsule. It's important to note this is a manufacturer decision, not a regulatory withdrawal by the FDA for safety issues. During shortages, your healthcare provider can help find alternative strategies, such as dose adjustments or considering a different class of medication. Always consult a medical professional before changing your medication plan.
