Is dofetilide available as a generic?
Yes. Dofetilide (used to treat certain abnormal heart rhythms, including atrial fibrillation/flutter and other tachyarrhythmias) is offered by multiple manufacturers as a generic product.
Which generic dofetilide brands and strengths are sold?
Generic dofetilide products are typically sold by strength (commonly including 125 mcg, 250 mcg, and 500 mcg), with packaging and appearance varying by manufacturer. Exact product availability depends on the country, pharmacy, and your prescribed dose.
Are there different “generics” that are not interchangeable?
Even when a drug is “generic,” switching between manufacturers can matter because of differences in tablet appearance, dosing increments, and (in rare situations) bioavailability. With dofetilide—an antiarrhythmic that requires careful dosing and monitoring—clinicians usually expect the dose and monitoring plan to remain consistent when switching products. If you’re switching manufacturers, tell your prescriber so dosing and follow-up (including kidney function and ECG monitoring) can be confirmed.
What does a dofetilide generic switch require clinically?
Dofetilide dosing is based on factors such as kidney function, and patients require monitoring for QT prolongation and heart rhythm response. When starting, restarting, or changing dosing, patients are generally monitored closely (including ECGs) to reduce the risk of serious arrhythmias. If your question is about switching from a brand to a generic (or between generics), the safe next step is coordinating with your prescriber/pharmacy to confirm the exact strength and that your monitoring schedule still fits.
Patent/exclusivity: when did or will the generic launch?
Generic entry depends on dofetilide’s patent and regulatory exclusivity status by jurisdiction.

How much cheaper is generic dofetilide?
Pricing varies widely by country, dose strength, and pharmacy contracts. In many markets, generic dofetilide is substantially cheaper than branded versions, but the exact cost depends on what strength you take and which manufacturer your pharmacy stocks.
What should I ask my pharmacist or doctor when filling dofetilide?
When you pick up generic dofetilide, confirm:
- The exact strength (mcg) matches your prescription
- The dosing schedule is unchanged
- Whether you’ve switched manufacturers compared with your last fill
- Whether your next ECG/lab monitoring date is still appropriate given the product or refill timing
