How to Help Your Patients Find Dofetilide in Stock: A Provider's Guide

If you're a cardiologist, electrophysiologist, or advanced practice provider who prescribes Dofetilide (Tikosyn), you've likely fielded calls from frustrated patients who can't get their refills. The ongoing Dofetilide shortage — now nearly three years old — has turned a routine prescription into a sourcing challenge that increasingly falls on your practice to help solve.

This guide provides actionable steps your practice can take to help patients find Dofetilide in stock, minimize treatment interruptions, and manage the operational burden of the shortage.

Current Availability Snapshot

As of early 2026, the Dofetilide market has consolidated to just two manufacturers:

• Novadoz — Generic Dofetilide capsules (125 mcg, 250 mcg, 500 mcg). Currently available but subject to intermittent supply disruptions at the wholesaler level.
• Pfizer (Tikosyn) — Brand capsules in all three strengths. Generally available but at significantly higher cost ($830+/month retail).

Accord and Sun Pharmaceutical have both permanently discontinued their generic Dofetilide products. No new entrants have been announced.

Why Your Patients Can't Find It

Even though the remaining manufacturers report available supply, patients encounter several barriers at the pharmacy level:

• Low stocking rates — Most retail pharmacies don't routinely stock Dofetilide due to low dispensing volume. It's typically a special-order item.
• Wholesaler allocation limits — During shortages, wholesalers may restrict quantities per pharmacy, meaning even pharmacies that want to order it may receive less than requested.
• Chain pharmacy limitations — Large chain pharmacies often have centralized purchasing, making it harder for individual store pharmacists to source shortage medications through alternative channels.
• Brand/generic confusion — Some pharmacies may only check one manufacturer's product. If the generic is out at their wholesaler, they may not think to try ordering brand Tikosyn (and vice versa).

5 Steps Your Practice Can Take

Step 1: Establish Pharmacy Partnerships

Identify one or two pharmacies in your area that reliably stock Dofetilide and build a relationship with them. Independent pharmacies and hospital outpatient pharmacies are often the best partners for this because they have more flexibility in sourcing. When you find a reliable pharmacy, direct your Dofetilide patients there proactively.

Step 2: Verify Supply Before Inpatient Initiations

Dofetilide requires a minimum 3-day inpatient stay for initiation with continuous ECG monitoring. Before admitting a patient for Dofetilide loading, have your staff confirm with the discharge pharmacy that they can fill the prescription. This prevents the costly and frustrating scenario of a successful initiation followed by inability to obtain outpatient supply.

Step 3: Use Availability Tools

Train your care coordinators and nursing staff to use Medfinder for Providers to quickly identify pharmacies with Dofetilide in stock. This tool lets you search by medication and location to find nearby pharmacies that currently have supply — eliminating the need for time-consuming phone calls to multiple pharmacies.

Step 4: Write Flexible Prescriptions

Consider prescribing in a way that gives the pharmacist maximum flexibility:

• Allow brand/generic substitution when possible
• If a patient needs brand Tikosyn specifically (e.g., insurance covers it or generic is unavailable), provide a separate brand-specific prescription
• Ensure prescriptions are transferable between pharmacies so patients can fill wherever stock is available

Step 5: Have a Transition Plan Ready

For each Dofetilide patient, know what your fallback antiarrhythmic would be if supply becomes completely unavailable. Document the alternative agent and any required monitoring in the chart. See our provider shortage briefing for guidance on choosing alternatives by cardiac substrate.

When to Consider Alternatives

Switching antiarrhythmics is never a casual decision, but certain situations may warrant it during the shortage:

• Patient has missed doses or had treatment gaps due to inability to find supply
• Cost of brand Tikosyn is prohibitive and generic remains unavailable in the patient's area
• Patient is relocating to an area with even less availability
• The patient has a suitable cardiac substrate for an alternative agent (e.g., no structural heart disease allows Class IC options)

For patients with heart failure, remember that Dofetilide and Amiodarone are the only antiarrhythmics with strong evidence for safety in this population. Switching to a non-evidence-based alternative in HF carries significant risk.

Workflow Tips for Your Practice

• Flag Dofetilide patients in your EHR — Create a patient list or registry of all patients on Dofetilide so your team can proactively monitor refill timing and supply issues.
• Set up a shortage protocol — Document a standard workflow for when patients report they can't fill: who they should call, what pharmacies to try, when to escalate to the prescriber.
• Educate patients at every visit — Remind patients to refill early, report problems immediately, and never stop the medication on their own.
• Track manufacturer updates — Monitor the ASHP Drug Shortages Database for any changes to manufacturer status or new entrants.

Final Thoughts

Drug shortages are an operational burden on practices, but for Dofetilide patients — many of whom have limited therapeutic alternatives — provider involvement can make the difference between staying on therapy and a dangerous treatment gap. By establishing pharmacy relationships, using availability tools, and maintaining contingency plans, your practice can help patients navigate this shortage safely.
