Shortage operations: substitutions, pharmacies, and the phone queue

What changes in a stimulant shortage, and what doesn't

A shortage changes which product a pharmacy can fill; it does not relax a single controlled-substance rule. Schedule II stimulants still cannot be refilled, still require a fresh prescription for each fill, and still cannot be phoned in except in the narrow emergency exception 1Ref 1Drug Enforcement Administration (2026).Diversion Control Division.That controlled-substance rules do not relax during a shortage — no refills on Schedule II, the narrow emergency-prescription exception, and recordkeeping and inspection standards that make stockpiling read as diversion.. So the shortage never creates a shortcut — it creates more prescribing events, more pharmacy calls, and more documentation. Your job is to keep patients supplied within rules that do not bend.

That framing matters because most of the bad moves in a shortage come from treating it as an exception to the usual discipline. It is not. Everything you already do for Schedule II — earliest-fill dates, the PDMP, complete records — stays exactly as it was, only with more volume flowing through it.

Confirm the shortage and map real supply

Before you change anything, confirm the current status, because shortage status shifts week to week and by formulation. The FDA's public drug shortage database is the authoritative place to check whether a specific product is actually in shortage and any resupply estimate. As of mid-2026, stimulant availability has been uneven across agents and manufacturers, so verify the specific drug and strength you prescribe rather than trusting a general headline about 'the Adderall shortage.'

Then map what your patients can actually get:

• Call the pharmacies your patients use and ask what they have in stock and expect, formulation by formulation.
• Check both brand and generic of the same molecule — one may be available when the other is not.
• Note which pharmacies will transfer a Schedule II prescription and which will not, so you route patients efficiently.

Substitutions are your clinical judgment, not the pharmacy's

When a product is unavailable, the substitution is a prescribing decision you make and document — a different formulation, a different agent, or a different strength combination — not something the pharmacy chooses for you. Get informed consent for the change, note the clinical reasoning, and run a fresh PDMP check on the new agent before you send it 2Ref 2PDMP Training and Technical Assistance Center (2026).Prescription Drug Monitoring Program Training and Technical Assistance Center.That a PDMP query is expected before controlled-substance prescribing, including when substituting to a new agent during a shortage.. A working prescription agreement makes these conversations easier, because expectations about substitutions were set before the shortage hit.

Keep the clinical logic visible in the note: why the usual product is unavailable, why the alternative is appropriate for this patient, and what monitoring the switch requires. That record is what turns an unusual prescribing pattern into a defensible one if it is ever reviewed.

When you do switch, tell the pharmacy directly what you intend rather than leaving it to interpret a prescription against an empty shelf. A short note about the clinical equivalence you are relying on, plus the earliest-fill dates on any sequential prescriptions, heads off a second round of calls and keeps the patient from bouncing between counters.

The phone and portal queue

A shortage turns your inbox into the bottleneck, so manage the queue deliberately instead of letting it manage you. Batch pharmacy callbacks, use saved message templates for the common questions, and reserve short telepsychiatry visits for the patients who actually need a reassessment before a switch 3Ref 3American Psychiatric Association (2026).Telepsychiatry Toolkit.The operational use of video-based psychiatric visits for reassessment before a medication switch during a shortage.. Run those visits on a HIPAA-compliant platform, not a consumer video-call app 4Ref 4HHS Office for Civil Rights (2026).HIPAA and Telehealth.That telehealth reassessment visits must run on a HIPAA-compliant platform now that pandemic enforcement discretion has ended.. Triage by clinical urgency, not by who emailed most recently.

• Templates for 'your pharmacy is out — here is the plan' save the most time.
• A single daily pharmacy-callback block beats interrupting sessions all day.
• Route the routine logistics to staff or the portal where your setup allows, keeping your synchronous time for real clinical decisions.

Prior authorization when you switch agents

An alternative agent often triggers a new prior authorization, and the shortage does not waive it. Calendar the PA the day you decide to switch, because approval can lag the patient's remaining supply. Submit the clinical rationale — the unavailable product, the shortage confirmation, the medical necessity of the alternative — and request a peer-to-peer review promptly if it is denied. Where a plan offers an expedited or urgent PA path, use it and document the timeline.

Track it in writing. Note the date you initiated the prior authorization, the plan's decision timeline, and each contact, so a delay is on the record if the patient runs short before approval lands.

If the patient's supply will not survive the PA timeline, decide the bridge deliberately — a short course of an available agent, a documented conversation about the plan, and a clear follow-up date — rather than letting the gap default into a missed dose. A planned bridge is a clinical decision you can defend; an unmanaged gap is not.

Communicating with patients without fueling panic

Patients read shortage headlines and arrive anxious, so lead the conversation before they do. Tell them what you know, what you are doing to keep them supplied, and what to do if a pharmacy turns them away — call you before switching pharmacies or rationing. Framed as an interruption of services you are actively managing, the disruption stays a clinical problem rather than a relationship rupture. Keep the reassurance honest; do not promise a supply you cannot guarantee.

A short, proactive portal message to affected patients — what is happening, what you are doing, and how to reach you — prevents most of the panicked calls before they start, and it is far less work than answering each one cold.

What not to do

Do not let a shortage push you into moves that outlast it. Writing early or larger prescriptions to stockpile is the pattern that reads as diversion in a records review, and it will not survive a DEA visit 1Ref 1Drug Enforcement Administration (2026).Diversion Control Division.That controlled-substance rules do not relax during a shortage — no refills on Schedule II, the narrow emergency-prescription exception, and recordkeeping and inspection standards that make stockpiling read as diversion.. Do not prescribe outside your scope to substitute, and do not invent a dispensing workaround — there is no opioid-treatment-program equivalent for stimulants, so the OTP boundary that governs methadone has no analog. When supply returns, resume your Schedule II logistics.

The steady-state disciplines are the ones that protect you in the disruption: a clean PDMP habit, complete records, informed consent for every switch, and honest patient communication. None of them costs anything a shortage takes away.
