Find out why Azstarys is so hard to find in 2026, including supply chain issues, DEA quotas, and insurance hurdles — plus what you can do right now.
You got the prescription. Your doctor said Azstarys was the right fit. But now you're calling pharmacy after pharmacy, hearing the same thing: "We don't have it in stock."
It's frustrating, and it's a problem thousands of ADHD patients are dealing with right now. Let's break down exactly why Azstarys is so hard to find in 2026 — and what you can actually do about it.
Azstarys is a brand-name prescription medication used to treat Attention Deficit Hyperactivity Disorder (ADHD) in patients 6 years of age and older. It contains two active ingredients: Serdexmethylphenidate (SDX), a prodrug, and Dexmethylphenidate (d-MPH), an immediate-release stimulant.
The prodrug component is what makes Azstarys unique. Serdexmethylphenidate is slowly converted into Dexmethylphenidate in your body, providing a smooth, long-lasting effect throughout the day. This means you get fast-acting symptom relief from the immediate-release portion, plus extended coverage from the prodrug — all in one daily capsule.
Azstarys is manufactured by Corium, a Sun Pharmaceutical company, and was approved by the FDA in 2021. It's classified as a Schedule II controlled substance, which is important context for understanding why it's hard to find.

There's no single reason Azstarys is difficult to locate at pharmacies. It's actually a combination of factors that all work together to create availability problems.
Because Azstarys is a Schedule II controlled substance, the Drug Enforcement Administration (DEA) sets annual limits on how much of the active ingredients can be manufactured. These quotas apply to all stimulant ADHD medications, including Adderall, Vyvanse, Concerta, Focalin, and Azstarys.
When demand for ADHD medications surges — as it has in recent years due to increased diagnoses and telehealth prescribing — manufacturers can't simply ramp up production to meet demand. They're capped by federal limits. This creates a supply-demand mismatch that ripples across the entire stimulant market.
Since late 2022, the United States has experienced a significant shortage of ADHD stimulant medications. While the shortage initially centered on Adderall and generic amphetamine salts, the ripple effects have impacted nearly every stimulant on the market.
When patients can't find their usual medication, they switch to alternatives — including Azstarys. This increased demand on a brand-name product with limited distribution makes it even harder to find. For the latest on the shortage situation, see our Azstarys shortage update for 2026.
As of early 2026, there is no generic version of Azstarys. It's only available as a brand-name product from Corium. This means there's only one manufacturer making it, and supply is entirely dependent on that single production line.
Generic medications typically have multiple manufacturers, which helps stabilize supply. Without a generic option, any production delay, quality issue, or shipping disruption at Corium's facilities can cause widespread stock-outs at pharmacies.
Many insurance plans don't cover Azstarys without prior authorization, and some require step therapy — meaning you have to try and fail on cheaper medications like generic Methylphenidate or Amphetamine salts before your plan will approve Azstarys.
This creates a situation where pharmacies may not stock Azstarys because they don't fill it often enough. If a pharmacy only fills a few Azstarys prescriptions per month, they may not keep it on their shelves at all — and when they do order it, it may take days to arrive.

The good news is you have options. Here are practical steps you can take today to find Azstarys.
Medfinder lets you search for Azstarys availability at pharmacies near you. Instead of calling dozens of pharmacies one by one, you can check stock in seconds. It's free and updated regularly.
Large chain pharmacies (CVS, Walgreens, Rite Aid) often run out of controlled substances first because they serve more patients. Independent pharmacies sometimes have better luck sourcing Schedule II medications from their wholesalers. Don't overlook smaller, local pharmacies in your area.
If one strength of Azstarys is out of stock, another might be available. Azstarys comes in three strengths: 26.1 mg/5.2 mg, 39.2 mg/7.8 mg, and 52.3 mg/10.4 mg. Your doctor may be able to adjust your prescription to a dose that's currently in stock.
If you consistently can't find Azstarys, talk to your doctor about alternative ADHD medications. Options like Focalin XR (Dexmethylphenidate ER), Concerta (Methylphenidate ER), or Vyvanse (Lisdexamfetamine) may be easier to find and work similarly.
Schedule II medications have strict rules about early refills — most states and pharmacies won't fill them more than a few days before your supply runs out. But filling at the earliest allowable date gives you the best chance of finding stock before it runs out.
Finding Azstarys in 2026 can be a real challenge, but understanding why it's hard to find is the first step toward solving the problem. Between DEA quotas, the ongoing stimulant shortage, brand-name-only availability, and insurance hurdles, there are multiple forces working against you.
But you're not powerless. Tools like Medfinder can help you locate Azstarys in stock near you, and your doctor can help you explore alternatives if needed. Don't give up — your ADHD treatment matters.
