Why Is Mydayis So Hard to Find? [Explained for 2026]

If You've Been Searching for Mydayis, You're Not Alone

You've called pharmacy after pharmacy. Each time, the answer is the same: "We don't have it in stock." If you take Mydayis for ADHD and you're struggling to find it, you're far from alone. Thousands of patients across the United States have been dealing with the same frustrating experience since late 2022 — and the problem hasn't fully gone away in 2026.

In this article, we'll explain exactly why Mydayis is so hard to find, what's causing the shortage, and — most importantly — what you can do about it right now.

What Is Mydayis?

Mydayis is a brand-name prescription medication used to treat Attention Deficit Hyperactivity Disorder (ADHD) in patients aged 13 and older. Its generic name is mixed amphetamine salts extended-release. It belongs to a class of drugs called CNS stimulants.

What makes Mydayis unique is its triple-bead delivery system. Unlike Adderall XR, which uses two beads to provide about 12 hours of coverage, Mydayis uses three beads to deliver up to 16 hours of symptom control. This makes it especially helpful for adults and teens who need longer-lasting focus throughout the day.

Mydayis comes in four strengths: 12.5 mg, 25 mg, 37.5 mg, and 50 mg extended-release capsules. It's manufactured by Takeda Pharmaceuticals (which acquired Shire, the original developer). It's a Schedule II controlled substance, which means it's tightly regulated by the DEA.

Why Is Mydayis So Hard to Find in 2026?

There's no single reason Mydayis is hard to find. It's a combination of factors that have been building for years. Here are the main ones:

1. The Ongoing Amphetamine Shortage

The nationwide shortage of amphetamine-based ADHD medications began in October 2022 when the FDA first reported supply issues. Teva Pharmaceuticals, one of the largest generic Adderall manufacturers, experienced production problems. This created a domino effect across the entire amphetamine supply chain — including Mydayis.

As of early 2026, the ASHP (American Society of Health-System Pharmacists) still lists multiple amphetamine extended-release products as being on back order. While some improvement has happened — particularly after the DEA increased production quotas in fall 2025 — intermittent shortages continue, especially for extended-release formulations.

2. DEA Production Quotas

Because Mydayis is a Schedule II controlled substance, the DEA sets annual limits on how much can be manufactured. These quotas are meant to prevent diversion and abuse, but they also cap how much medication is available — even when patient demand is high.

The DEA did increase amphetamine production quotas in 2025, which has helped. But it takes time for manufacturers to ramp up production, and the increased supply hasn't fully caught up with demand.

3. Rising ADHD Diagnoses and Demand

ADHD diagnoses have been increasing steadily, particularly among adults. More patients are seeking treatment, and many are prescribed stimulant medications like Mydayis, Adderall XR, and Vyvanse. This surge in demand puts additional pressure on an already strained supply.

Telehealth has also made it easier for patients to get diagnosed and receive prescriptions, which further increases demand for these medications.

4. Mydayis Is a Niche Medication

Mydayis is not as widely prescribed as Adderall XR or Vyvanse. Because it serves a smaller patient population, pharmacies are less likely to keep it regularly in stock. When supply is tight across all amphetamine products, pharmacies tend to prioritize stocking the medications they dispense most frequently.

This means even when Mydayis is technically available from the manufacturer, your local pharmacy may not have ordered it — or may have run out quickly.

What You Can Do Right Now

The shortage is frustrating, but there are concrete steps you can take to improve your chances of getting your Mydayis prescription filled.

Use Medfinder to Check Pharmacy Availability

Medfinder helps you search for pharmacies that currently have your medication in stock. Instead of calling dozens of pharmacies one by one, you can check availability in your area quickly. It's free and updated regularly.

Try Independent and Specialty Pharmacies

Large chain pharmacies often run out of controlled substances faster because they serve more patients. Independent pharmacies and compounding pharmacies may have better luck sourcing Mydayis. They often have more flexibility in ordering from different wholesalers.

Ask Your Doctor About Alternatives

If you simply cannot find Mydayis, your prescriber may be able to switch you to an alternative medication temporarily. Options include Adderall XR, Vyvanse, Concerta, or Jornay PM. Each works a little differently, so it's important to discuss the switch with your doctor. Read more in our article on alternatives to Mydayis.

Call Ahead and Be Flexible on Timing

If you're nearing the end of your current supply, call pharmacies early in the month. Many pharmacies receive their controlled substance shipments at the beginning of the month. Calling on a Tuesday or Wednesday morning can also improve your odds, since that's when many wholesaler deliveries arrive.

Don't Split or Skip Doses

It can be tempting to stretch your remaining supply by taking less. But changing your dose without medical guidance can lead to withdrawal symptoms or a return of ADHD symptoms. Always talk to your prescriber before making any changes.

Final Thoughts

The Mydayis shortage is a real and ongoing challenge in 2026. It's driven by a combination of DEA quotas, manufacturer supply issues, and increasing demand for ADHD medications. While the situation has improved somewhat since the worst of the shortage in 2022-2023, finding Mydayis still requires persistence and planning.

The good news is that you have options. Tools like Medfinder can help you locate pharmacies with stock. Your prescriber can help you explore alternatives if needed. And staying informed — like you're doing right now — is one of the best things you can do.
