Cytomel is Pfizer’s brand of liothyronine, the synthetic T3 thyroid hormone. Six manufacturers sell an AB-rated generic version of it, which usually means the brand costs many times the generic and the advice writes itself. On this molecule it does not. The brand-versus-generic gap is one of the narrowest in the thyroid category, and in one federal dataset it runs backwards.
This guide covers what a cash payer pays for both in September 2026, where the two diverge, and why the usual discount playbook (Walmart’s program, a manufacturer coupon) does not apply here. All figures were pulled fresh on September 4, 2026 from CMS datasets, FDA’s approval database, Cost Plus Drugs and the Drugs.com cash price guide. This is price and paperwork only, not clinical advice.
What Does Cytomel Cost Without Insurance?
Drugs.com publishes brand Cytomel only in a 100-tablet package, so the 30-day figures below are that per-tablet price multiplied by 30. Generic liothyronine is sold in more package sizes, which is where the strange part shows up: the 30-count generic fill is the most expensive per tablet of any option on this page.
| Service/Type | Low | Average | High |
|---|---|---|---|
| Generic liothyronine, 30 tablets (Cost Plus) | $7.69 (5 mcg) | $8.97 (25 mcg) | $11.45 (50 mcg) |
| Generic liothyronine, 30 tablets (retail cash) | $21.37 (25 mcg) | $21.37 | $21.37 |
| Brand Cytomel, 30-day supply (derived) | $13.78 (5 mcg) | $18.56 (25 mcg) | $29.87 (50 mcg) |
| Generic liothyronine, 90 tablets | $32.19 (5 mcg) | $53.20 (25 mcg) | $78.46 (50 mcg) |
| Brand Cytomel, 100 tablets | $45.93 (5 mcg) | $61.87 (25 mcg) | $99.56 (50 mcg) |
| National acquisition cost, per tablet | $0.22006 (generic 5 mcg) | $0.32166 (generic 25 mcg) | $0.53213 (Cytomel 25 mcg) |
Sources: Cost Plus Drugs liothyronine product pages (30-count basis, plus roughly $5 standard shipping), the Drugs.com price guides for Cytomel and liothyronine, and the CMS National Average Drug Acquisition Cost file effective August 19, 2026. Cytomel 30-day figures are the published 100-count price divided by 100 and multiplied by 30, at one tablet a day.
Two things in that table are worth pausing on. First, buying only 30 generic tablets at retail costs $21.37 at 25 mcg, or 71 cents a tablet, which is more per tablet than the 62 cents brand Cytomel works out to in a 100-count package. Second, Cost Plus at $8.97 for the same 30 tablets is under half the retail generic price and under half the brand.
What Drives the Price
The brand premium is small, and in 2024 it was negative. In CMS’s Medicare Part D Spending by Drug file for 2024, brand Cytomel averaged $0.4001 per dosage unit across 8,950 claims while generic liothyronine sodium averaged $0.4196 per dosage unit across 748,503 claims. The brand was cheaper. Cytomel’s own figure had fallen from $2.0345 per dosage unit in 2023, a drop of about 80 percent in a single year with claim volume flat.
Acquisition cost tracks that collapse. In the CMS acquisition file effective August 19, 2026, Cytomel runs $0.38564 per 5 mcg tablet and $0.53213 per 25 mcg tablet, against $0.22006, $0.32166 and $0.37291 for generic liothyronine at 5, 25 and 50 mcg. That is a brand premium of about 1.65x to 1.75x, not the 20x or 50x that usually separates a brand from its generic. At retail the gap narrows further: Drugs.com prices a 100-count of brand Cytomel at $0.62 per 25 mcg tablet against $0.58 for the generic, a difference of four cents.
Strength moves the price more than branding does. At Cost Plus, 30 tablets of the 50 mcg generic cost $11.45 against $7.69 for the 5 mcg, about 1.5 times. At retail the same jump is steeper: 100 generic tablets run $86.71 at 50 mcg against $34.65 at 5 mcg, roughly 2.5 times. With most thyroid drugs the strength barely moves the price. Here it moves it more than the brand name does.
Package size is the other lever. The 1,000-tablet generic price on Drugs.com works out to 49 cents a tablet at 25 mcg against 71 cents for a 30-count. Pharmacies price small fills at a premium, so a 90-day prescription is usually cheaper per tablet than three 30-day ones.
There is no program floor. Walmart’s prescription program list, effective 03/24/2025, contains no liothyronine and no Cytomel at any tier. The Thyroid block on page 2 holds levothyroxine only, at $4 for 30 days and $10 for 90 across 11 strengths. Nothing pulls T3 pricing down to a fixed low number the way that program does for T4.
The Cytomel and Liothyronine Coupon Question
There is no manufacturer coupon for either one, and that is a sourced fact rather than an absence of searching.
Pfizer’s own product page for Cytomel lists no copay card or savings program. It offers a single link, to Pfizer RxPathways, which is Pfizer’s patient assistance umbrella rather than a discount card. Drugs.com’s coupon section for both Cytomel and liothyronine says the same thing in plain language: “No manufacturer promotions could be found for this medication.”
That is actually good news for a cash payer. Manufacturer savings cards routinely exclude uninsured and government-insured patients in their fine print, so their absence here costs you less than it sounds. The discounts that do work on this molecule are the ones anyone can use: a discount pharmacy, a discount card, or a larger package size.
The one assistance route Drugs.com does list for Cytomel is Rx Outreach, a nonprofit mail-order pharmacy that ships to all 50 states and does not require you to be uninsured. It does not publish prices on its public pages, so you have to call or enroll to get a quote.
Cash Price vs. Insurance
Because the absolute numbers here are small, running liothyronine through insurance often costs more than paying cash. A $10 or $15 generic copay is above the $8.97 Cost Plus charges for 30 tablets, and on a high-deductible plan you pay the full negotiated price anyway until the deductible clears.
Ask the pharmacy for the cash price and the insurance price as two separate quotes and take the lower one. That is a legal request in every state, and pharmacists can no longer be gagged from telling you. Our fair price checker will tell you whether a quote sits inside the published range for this drug.
The one case for using coverage is brand Cytomel on a plan that puts it on a preferred tier, since the brand carries no discount-pharmacy option at all. Cost Plus Drugs stocks generic liothyronine at three strengths and does not carry brand Cytomel.
How to Pay Less
Price Cost Plus Drugs first. At $7.69 to $11.45 for 30 tablets plus about $5 shipping, it is the cheapest published route with no eligibility screening. It carries the 5, 25 and 50 mcg generic strengths, which covers the full Cytomel range.
Ask for a 90-day fill. Ninety generic tablets run $32.19 to $78.46 on Drugs.com against $21.37 for just 30 at 25 mcg. The per-tablet price falls sharply with quantity, and the 1,000-count price falls further still.
Compare the brand before you assume the generic wins. This is the rare drug where the two are within pennies of each other, and where a small generic fill can cost more per tablet than the brand. Get both quoted.
Check discount cards, but check them against Cost Plus. Card prices on cheap generics are often no better than a mail-order pharmacy. Our GoodRx vs. SingleCare comparison explains how to read the quotes and where the cards actually help.
Budget for the monitoring, not just the pills. Refills usually depend on periodic lab work billed separately from the prescription. See thyroid test costs for cash lab pricing, and if you are uninsured, a sliding-scale clinic can often cover the visit and the draw together for less than a retail lab menu.
Push back on an inflated bill. If a pharmacy quotes far above the ranges here, or a related office or lab bill lands higher than expected, our guide to negotiating medical bills has the scripts for the call.
The Bottom Line
A cash payer should expect roughly $8 to $15 a month for generic liothyronine and roughly $14 to $30 a month for brand Cytomel in September 2026, with the exact figure driven more by strength and package size than by the brand name. The retail generic 30-count at $21.37 is the trap: it costs more per tablet than either the brand or a mail-order fill.
There is no coupon to hunt for on this one, which simplifies the decision. Pick the cheapest pharmacy, ask for the largest quantity your prescriber will write, and compare brand and generic quotes rather than assuming.
