Flecainide is one of the least expensive drugs a cardiologist prescribes and one of the most closely watched. The tablets cost a pharmacy about eleven cents each. The boxed warning attached to them, and the electrocardiograms and follow-up visits that warning drives, cost considerably more than the prescription.
The other thing that makes flecainide pricing unusual is that not everyone takes it daily. Some patients with paroxysmal atrial fibrillation are prescribed it as a single as-needed dose taken when an episode starts, which changes the monthly arithmetic completely. This guide prices both patterns. Every figure was researched on September 4, 2026.
What Does Flecainide Cost Without Insurance?
Acquisition costs come from the CMS National Average Drug Acquisition Cost survey, effective August 19, 2026. Retail and card prices come from SingleCare’s flecainide page, which states its prices were updated September 4, 2026, and from Cost Plus Drugs, read the same day. Procedure figures are 2024 national averages from the CMS Medicare Physician and Other Practitioners by Geography and Service file. Plan-payment figures come from the CMS Medicare Part D Spending by Drug dataset.
| Item | Low | Typical | High |
|---|---|---|---|
| Flecainide 50 mg, 30 tablets | $3.35 (CMS acquisition cost) | $7.00 (Cost Plus Drugs) | $53.10 (retail Cost Plus quotes for other pharmacies) |
| Flecainide 100 mg, 30 tablets | $5.21 (CMS acquisition cost) | $8.07 (Cost Plus Drugs) | $66.30 (retail Cost Plus quotes for other pharmacies) |
| Flecainide 150 mg, 30 tablets | $7.77 (CMS acquisition cost) | $9.02 (Cost Plus Drugs) | $90.90 (retail Cost Plus quotes for other pharmacies) |
| One month at 50 mg twice daily (60 tablets) | $6.71 (CMS acquisition cost) | $13.91 (SingleCare card price) | $93.85 (SingleCare undiscounted retail) |
| One year at 50 mg twice daily | $82 | $167 | $1,126 |
| Flecainide 150 mg, cost of a single tablet | $0.26 (CMS acquisition cost) | $0.30 (per tablet inside a Cost Plus 30 count) | $3.03 (per tablet at the quoted retail price) |
| Average Medicare Part D payment per fill | $41.53 (2024) | $61.72 (2023) | $85.82 (2020) |
| Routine 12-lead ECG, CPT 93000 | $13.32 (allowed, facility) | $14.20 (allowed, office) | $69.03 (average billed charge) |
| Cardiology follow-up visit, CPT 99214 | $90.37 (allowed, facility) | $119.71 (allowed, office) | $276.45 (average billed charge) |
| First year of therapy: drug plus two visits and two ECGs | $350 | $435 | $1,817 |
The first-year row is where the real budget sits. At Medicare-allowed rates for two follow-up visits and two ECGs plus a year of tablets at acquisition cost, the package is about $350. At average billed charges with undiscounted retail pharmacy pricing, the same year is $1,817. The tablets account for well under a tenth of the gap.
Cost Plus Drugs publishes the components of its price, which makes a 60 tablet month easy to work out. The $8.07 charge for 30 of the 100 mg tablets is $2.67 of manufacturing cost, a $0.40 markup and a flat $5.00 pharmacy labor fee, with $5.25 standard shipping added at checkout. Because the labor fee is flat, a 60 tablet fill of the same strength lands near $11 before shipping.
What Drives the Price
Daily dosing versus pill in the pocket. A patient on 100 mg twice daily uses 730 tablets a year. A patient taking a single as-needed dose during episodes may use a couple of dozen. At CMS acquisition prices that is the difference between about $127 and about $6 of drug. In practice the as-needed patient does not save 95 percent, because the dispensing fee is charged per fill rather than per tablet, and every pricing model on this page has one: $5.00 at Cost Plus, and a fee baked into every retail and card price.
The strength you are on. Flecainide comes in 50, 100 and 150 mg tablets, and the acquisition price per tablet runs $0.11176, $0.17375 and $0.25897 respectively. Per milligram the 150 mg is the cheapest and the 50 mg the most expensive, so two 50 mg tablets cost more than one 100 mg tablet. This is worth raising with the prescriber only as a pharmacy question, never as a reason to split or combine doses on your own.
Where you buy it. SingleCare’s own page put the undiscounted retail price of 60 of the 50 mg tablets at $93.85 and its card price at $13.91 on the same day. Its per-pharmacy table that day showed retail prices for the same fill ranging from $39.94 to $166.80 across five chains. Those chain-level rows shift from day to day and should be read as evidence of spread rather than as quotes, but the spread itself is consistent.
The monitoring the label attaches to the drug. The prescribing information instructs prescribers to obtain plasma trough flecainide levels and electrocardiograms at presumed steady state after initiation or any dose change, and states that use for sustained ventricular tachycardia should be initiated in the hospital. It also notes that patients treated for atrial flutter have been reported with 1 to 1 atrioventricular conduction, and that concomitant negative chronotropic therapy such as digoxin or a beta blocker may lower that risk. That is why many patients are started on flecainide alongside a rate-control drug, and why our metoprolol cost guide and diltiazem cost guide are worth reading next.
Billed charge versus allowed rate on the tests. The gap on cardiac diagnostics is wide. A routine 12-lead ECG with interpretation was billed at an average of $69.03 in an office setting in 2024 against a Medicare-allowed amount of $14.20, and the interpretation-only code (CPT 93010) was billed at an average of $45.37 from facilities against $7.96 allowed. If ambulatory monitoring is ordered to check whether the drug is working, the numbers get larger: CPT 93224, the full 48 hour Holter service, averaged $380.34 in submitted charges against $68.10 allowed. Our guides to EKG costs without insurance and Holter monitor costs have the cash prices for each.
Cash Price vs. Insurance
On the tablets, cash almost always wins. A $13.91 card price or an $11 mail-order fill undercuts most commercial copays, and CMS data shows Part D plans paid an average of $41.53 per flecainide fill in 2024, so running the claim is frequently the more expensive path for the plan and for you.
On the ECGs, the visits and any monitoring, the calculation flips. The gap between a $276.45 average submitted charge and a $119.71 allowed amount for the same office visit is not something a self-pay patient closes at the counter. If you have any coverage, use it for the clinical side even when you pay cash for the pills.
If you are fully self-pay, ask for the self-pay rate before the test is performed, not after. Hospitals are required to publish machine-readable cash prices, and our guide to hospital price transparency walks through reading one before you book. Run any quote through our fair price checker first.
Worth stating plainly: the monitoring is not a cost you can skip your way out of. It exists because the label carries a boxed warning built on the Cardiac Arrhythmia Suppression Trial, in which the mortality or non-fatal cardiac arrest rate was 5.1 percent on flecainide against 2.3 percent on placebo in post-infarction patients. This page is about what that surveillance costs and how to pay less for it, not about whether to have it.
How to Pay Less
-
Price the fill you actually need, in tablets. A twice-daily prescription is 60 tablets a month, not 30, and card sites default to whatever quantity is in the URL. If you are on the pill-in-the-pocket approach, ask what the smallest fill costs, because below a certain tablet count you are buying a dispensing fee with a few tablets attached.
-
Check a free discount card before you fill. SingleCare published a $13.91 card price against its own $93.85 undiscounted retail price for 60 of the 50 mg tablets on September 4, 2026. Which card wins changes by drug and by pharmacy, so check more than one: our comparison of GoodRx vs. SingleCare covers how.
-
Compare a transparent mail pharmacy. Cost Plus Drugs lists 30 tablets at $7.00 (50 mg), $8.07 (100 mg) and $9.02 (150 mg) with a flat $5.00 labor fee inside each and $5.25 shipping at checkout. Because the fees are flat, filling 90 days at once is materially cheaper per dose than three monthly fills.
-
Shop the ECG separately from the clinic that orders it. An ECG order travels with you, and the same tracing that a facility bills at an average of $69.03 can often be bought for far less as a published cash price at a clinic or urgent care. Our EKG cost guide has current self-pay ranges by setting.
-
Ask what category any heart monitor falls into before you agree to it. A 48 hour Holter, a 14 day patch and continuous mobile telemetry are three very different bills for what feels like the same errand. The Holter monitor cost guide breaks down which code is which.
-
Use a sliding-scale clinic for the routine visits, and negotiate anything that arrives anyway. A free or sliding-scale clinic can handle refills and routine checks on an income-based fee. When a bill shows up at the billed-charge rate rather than the allowed rate, our guide to negotiating medical bills and our negotiation script tool will get you a draft for the specific charge.
Bottom Line
Flecainide itself is a $7 to $14 a month drug for anyone who uses a card or a transparent pharmacy, and a $94 a month drug for anyone who pays sticker price at a chain counter. Brand Tambocor is discontinued, so there is no brand premium in play, only a retail one.
Plan the first year at $350 to $1,817 rather than the price of the pills, because two cardiology visits and two ECGs cost several times what the tablets do. If a different antiarrhythmic gets considered, both our sotalol cost guide and our amiodarone cost guide tell the same story from the other end: an inexpensive drug with an expensive monitoring requirement bolted to it.
