How to Help Your Patients Find Azstarys (Dexmethylphenidate/Serdexmethylphenidate) In Stock: A Provider's Guide

As a prescriber of Azstarys (serdexmethylphenidate/dexmethylphenidate), you've likely encountered patients who return to your office — or call your practice — unable to fill their prescription. This is a common frustration in 2026: while Azstarys is not in an official FDA-declared shortage, it is a brand-only medication that many pharmacies do not stock routinely. This guide gives you practical, actionable strategies to help your patients find Azstarys before you even write the prescription.

Why Proactive Stock Verification Matters

For Schedule II controlled substances like Azstarys, prescriptions cannot be called into a pharmacy — they must be sent electronically (EPCS) or issued on a written prescription. This means that if a patient discovers their pharmacy doesn't have Azstarys in stock after the prescription is already sent, they face a multi-step process to redirect it. Proactive stock verification before writing the prescription prevents this friction entirely.

Step 1: Verify Stock Before Writing the Prescription

The most efficient approach: before sending an electronic prescription, confirm that the patient's preferred pharmacy has Azstarys in the correct dosage in stock. There are two practical ways to do this:

Recommend medfinder: Direct your patient to medfinder before their visit. medfinder calls pharmacies near the patient to check for Azstarys stock and texts them results — they can identify a pharmacy with availability before the prescription is written.

Have your office call ahead: Some practices designate staff to call 1–2 local pharmacies to verify stock for brand-only medications before sending new prescriptions. This adds minimal workflow overhead and significantly reduces patient frustration.

Step 2: Educate Patients on Which Pharmacies to Try First

Not all pharmacies are equally likely to stock Azstarys. Coach your patients on the search hierarchy:

Large chain pharmacies first: CVS, Walgreens, Walmart, and Costco pharmacies generally order larger quantities and are more likely to have brand-only stimulants like Azstarys.

Hospital outpatient pharmacies: These tend to stock a broader formulary, including brand-name specialty medications.

Specialty pharmacies: Pharmacies that focus on specialty or brand medications may maintain more reliable Azstarys stock.

Independent pharmacies: Worth calling; they may use different wholesalers with different stock.

Step 3: Help Patients Navigate Insurance Hurdles

Many plans require prior authorization (PA) or step therapy for Azstarys. Here's how to streamline this process:

Anticipate PA requirements: When initiating Azstarys for a new patient, check the plan's formulary before the appointment and initiate PA paperwork proactively.

Document step therapy completion: If the plan requires proof that generic dexmethylphenidate or other formulations were tried first, have this documentation ready.

Refer patients to the CoriumCares savings program: Commercially insured patients pay $60 or less per fill; first prescription is $0. This can eliminate cost barriers during the PA process.

Step 4: Have a Contingency Plan Ready

Even with proactive stock verification, circumstances change. Have a pre-planned alternative ready to prescribe in case Azstarys becomes unavailable for a patient mid-treatment:

Document the patient's approximate dexmethylphenidate equivalent dose for reference if you need to switch to generic dexmethylphenidate ER

Remind patients not to wait until their last dose to start looking for refills — Schedule II stimulants have early-refill restrictions (typically a few days before supply runs out)

Note which other ADHD medications have worked or not worked for this patient, so substitution decisions can be made quickly if needed

Step 5: Consider Mail Order for Eligible Patients

Mail-order pharmacies — especially insurance plan-affiliated specialty pharmacies — often maintain more reliable inventory of brand-only medications than local retail pharmacies. If a patient has consistent difficulty filling Azstarys locally, discuss whether their insurance plan offers mail-order coverage for Schedule II controlled substances. Regulations vary by state.

When to Consider Switching to an Alternative

If Azstarys remains consistently unavailable for a patient after 2–3 fill attempts, a planned therapeutic switch may be more appropriate than continued searching. See our full provider guide for substitution guidance: Azstarys Shortage: What Providers and Prescribers Need to Know in 2026.
