How to Check If a Pharmacy Has Mydayis XR in Stock (Without Calling)

If you take Mydayis XR, you've probably been here: it's almost time for a refill, you call three pharmacies, get put on hold, and each one tells you it's out of stock. It's frustrating, time-consuming, and stressful when you're managing a condition that requires consistent medication.

The good news: you don't have to call anymore. Here's a practical guide to checking Mydayis XR pharmacy availability without spending your lunch break on hold.

Why Is Mydayis XR Hard to Find in Pharmacies?

Mydayis XR is a Schedule II controlled substance subject to DEA production quotas, and it's part of the broader amphetamine shortage that began in October 2022 and continues into 2026. The DEA increased production quotas for d-amphetamine by 25% in October 2025, but supply hasn't fully caught up with demand yet.

There's also a Mydayis-specific factor: it's a newer and less commonly prescribed medication, so many pharmacies don't keep it in regular standing inventory. For a deeper explanation, read our article on why Mydayis XR is so hard to find. The bottom line: you may need to be strategic about finding it.

The Fastest Way: Use Medfinder

The quickest way to check Mydayis XR availability without making a single phone call is to use Medfinder. Medfinder checks real-time pharmacy inventory for controlled substances near you — the kind of information that isn't available on standard pharmacy websites.

Here's how it works:

1. Enter your medication (Mydayis XR) and your zip code
2. Select the strength and quantity you need
3. See which nearby pharmacies currently have your medication in stock
4. Ask your prescriber to send the e-prescription to that specific pharmacy

This is the critical advantage: because Mydayis is Schedule II, your doctor sends the prescription electronically. If you find the pharmacy with stock BEFORE the prescription is sent, you avoid the frustration of a prescription sitting at a pharmacy that can't fill it.

Other Tools for Checking Pharmacy Stock

While Medfinder is the most purpose-built tool for this task, here are other options to try:

• GoodRx — GoodRx's "Find a Pharmacy" feature shows which pharmacies have the drug on file, though it doesn't always reflect real-time controlled substance inventory. Still useful for comparing prices.
• Direct pharmacy websites — CVS, Walgreens, and Costco have online tools that let you check drug availability. The accuracy varies for controlled substances, but it's worth a quick check before going in person.
• Your pharmacy's app — Many chain pharmacies have apps that let you check medication transfer status or alert you when a prescription is ready. Set up notifications so you know immediately if there's a delay.
• Pharmacy live chat — Many major pharmacy websites now have chat features. Use these to ask about stock before making a trip or sending a prescription.

Smart Pharmacy Strategies for Finding Mydayis XR

Beyond using search tools, here are strategies that improve your odds:

• Try independent pharmacies. Independent pharmacies often have different wholesale relationships than chain pharmacies and may have access to stock that the big chains don't. They're consistently worth checking during shortages.
• Try compound or specialty pharmacies. These pharmacies specialize in harder-to-find medications and often stock Mydayis for patients with ongoing prescriptions.
• Check mail-order pharmacy options. Your insurance plan's mail-order pharmacy sometimes draws from different supply channels. Call ahead to confirm Mydayis is available before switching.
• Look for generic first. The FDA-approved generic version (mixed amphetamine salts ER, triple-bead) is the same medication and is sometimes easier to find. Always ask for generic when checking availability.
• Check early in the month. Pharmacies often receive new shipments early in the month. Checking stock in the first week of the month tends to yield better results.
• Start looking a week before you run out. Don't wait until the last day. Give yourself a 7–10 day buffer to find stock and coordinate with your prescriber.

What to Do If No Pharmacy Has It in Stock

If Mydayis XR is genuinely not available in your area, contact your prescriber. They may be able to:

• Prescribe a different strength (sometimes a specific dose is out of stock while others are available)
• Prescribe the generic version specifically (rather than brand Mydayis)
• Temporarily switch you to an alternative ADHD medication that is more available
