Levothyroxine is the most-dispensed prescription in the United States and one of the least expensive. Medicare Part D alone covered 43.3 million generic levothyroxine claims in 2024 for 9 million people at an average of $10.73 per claim. A tablet costs a pharmacy between three and ten cents.
So the question is not whether you can afford it. The question is which of the six or seven branded versions you ended up on and whether anyone told you the generic exists. Brand Synthroid accounted for roughly a tenth of thyroid-hormone prescriptions in that same Part D data and about four in every ten dollars spent on them. Every figure below was researched on September 3, 2026.
What Does Levothyroxine Cost Without Insurance?
Acquisition costs come from the CMS National Average Drug Acquisition Cost survey, with rows effective August 19, 2026 (the 175 mcg generic row was refreshed August 26). Cash prices come from Walmart, Cost Plus Drugs, Drugs.com and AbbVie’s own Synthroid pages, all read September 3, 2026.
| Option | Low | Average | High |
|---|---|---|---|
| CMS NADAC acquisition cost, one generic tablet | $0.03568 (25 mcg) | $0.05073 (100 mcg) | $0.09986 (300 mcg) |
| Walmart Prescription Program, 30-day supply | $4.00 | $4.00 | $4.00 |
| Walmart Prescription Program, 90-day supply | $10.00 | $10.00 | $10.00 |
| Cost Plus Drugs, 30 tablets (plus $5.25 shipping) | $5.90 (25 mcg) | $6.10 (100 mcg) | $6.41 (200 mcg) |
| Drugs.com cash price, 90 generic tablets | $9.43 | $9.43 | $60.46 (300 mcg high) |
| Retail comparison, 30 generic tablets, no program | $15.90 (25 mcg) | $16.80 (100 mcg) | $21.30 (200 mcg) |

| CMS NADAC acquisition cost, one Levoxyl tablet | $0.75256 (25 mcg) | $0.96963 (100 mcg) | $1.38930 (175 mcg) |
| CMS NADAC acquisition cost, one Unithroid tablet | $4.17871 (25 mcg) | $4.20778 (100 mcg) | $4.24445 (200 mcg) |
| Tirosint gel caps, 30 count | $56.75 (Cost Plus) | $111.70 (generic capsule) | $169.00 (retail comparison) |
Two things jump out of that table. First, the generic is close to free by the standards of American drug pricing: at $0.05073 a tablet, a year of 100 mcg levothyroxine contains about $18.52 of actual medicine. Everything above that is dispensing.
Second, the sources disagree about what a plain, unhelped retail fill costs, and the honest answer is a range. Cost Plus publishes retail comparisons of $15.90 to $21.30 for 30 tablets. Drugs.com’s cash prices for 90 tablets run from $9.43 at the low end to between $19.67 and $35.87 at the high end depending on strength, with the rarely used 300 mcg reaching $60.46. Call it $10 to $36 a month at retail without a program, against $4 to $13 with one.
Synthroid vs. Generic Levothyroxine
Synthroid is levothyroxine sodium made by AbbVie, and it is the reason this page exists: it is still America’s most prescribed branded hypothyroidism medication despite an identical generic selling for a fraction of the price.
The gap at the counter is enormous. In the August 2026 CMS acquisition data a Synthroid tablet costs a pharmacy $1.65631 to $1.66372 depending on strength, while a generic levothyroxine tablet costs $0.03568 to $0.09986. At retail, Drugs.com lists Synthroid at $160.59 to $160.83 for 90 tablets, against $9.43 for 90 generic tablets. That is roughly 17 times the money for the same active ingredient.
AbbVie closes most of that gap itself, if you ask. The Synthroid Delivers Program is a cash-only home delivery service run by Eagle Pharmacy on AbbVie’s behalf, and its published terms price brand Synthroid at $29.50 for a standard 30-tablet prescription, $54.00 for 60 tablets and $75 for 90 tablets, with free standard shipping (2-day is $12, overnight $25). AbbVie markets that as “as low as $25 a month,” which is the 90-day price divided by three, so read the fine print before you plan a budget around $25.
The separate Synthroid copay card is aimed at commercially insured patients at as little as $25 a month, but its own terms spell out what an uninsured person pays: $39.95 for a 30-day prescription and $99.90 for a 90-day prescription. Neither program is available to anyone whose prescriptions are paid in whole or part by Medicare including Part D, Medicare Advantage, Medigap, Medicaid, TRICARE, the Department of Defense or Veterans Affairs. AbbVie’s savings page also points cash payers to Amazon Pharmacy, the Costco Membership Pharmacy Program and TrumpRx as additional routes.
The catch worth understanding: the Delivers Program bypasses insurance entirely by design, and AbbVie’s terms state that what you pay through it cannot be applied toward Medicare Part D true out-of-pocket costs. If you are chasing a deductible, that is money that does not count.
What Drives the Price
Brand versus generic, by a mile. Nothing else on this page moves your bill as much. Medicare Part D data for 2024 shows generic levothyroxine at $0.16938 per dosage unit and $10.73 per claim, against Synthroid at $0.98780 per unit and $69.75 per claim. Same molecule.
Which brand, because they are not priced alike. Euthyrox is the cheap one, at $0.09232 per dosage unit and $7.01 per claim in that same 2024 Part D data, which is less than the generic average. Levoxyl sits at $0.51808 per unit, Unithroid at $0.58122, Synthroid at $0.98780, and Tirosint at $4.48285. At acquisition cost the ordering shifts again: Unithroid is the most expensive tablet at about $4.18 to $4.24 apiece, more than twice Synthroid’s $1.66, which tells you how differently these products are rebated versus listed.
Formulation, not dose. Tirosint is a soft gel capsule and Tirosint-SOL is a liquid, both from IBSA, with no interchangeable generic to switch to. Cost Plus Drugs prices a 30-capsule carton of Tirosint 100 mcg at $56.75 against a $169.00 retail comparison, and its own cost breakdown shows $45.00 of that is manufacturing before any markup or labor. Drugs.com lists the generic levothyroxine oral capsule at $111.70 for 30 at every strength.
Not strength, which is the surprise. Levothyroxine comes in 12 oral strengths from 25 to 300 mcg, and price barely tracks dose. Cost Plus charges $5.90 for 30 of the 25 mcg and $6.41 for 30 of the 200 mcg. Every Synthroid strength in the CMS file sits within a penny of $1.66. If you are ever quoted a much higher price because your dose went up, that is a pharmacy pricing decision, not a manufacturing one.
Whether you use a program at all. The difference between $4 at Walmart and roughly $21 at a counter for the same 30 tablets is about $200 a year on a drug most people take for life.
Cash Price vs. Insurance
Levothyroxine is the clearest case on this site for skipping your insurance card. A $4 Walmart fill or a $6.10 Cost Plus order beats almost any generic copay, and it beats the hassle of a prior authorization if your plan happens to require one for a specific brand.
The standard tradeoff applies. Cash spending does not count toward your deductible or out-of-pocket maximum, and you cannot combine a discount card with insurance on a single fill. On a drug costing $4 a month, that lost credit is not worth thinking about. It becomes a real question only if you are also filling something expensive, which is the same conclusion our metformin cost guide and atorvastatin cost guide reach.
The one place cash payers get hurt is brand loyalty without a program. Paying $160 at a pharmacy counter for 90 Synthroid tablets when the manufacturer will sell you the identical 90 tablets for $75 is a pure information gap. If a pharmacy quotes you a three-figure price for any levothyroxine product, run it through our fair price checker before you pay.
How to Pay Less
-
Check Walmart’s program list first, and read the tier. Walmart’s Prescription Program drug list, effective March 24, 2025, covers levothyroxine 25, 50, 75, 88, 100, 112, 125, 137, 150, 175 and 200 mcg under a Thyroid heading in the $4 per 30 days and $10 per 90 days tier. Do not assume that rate carries to your other prescriptions: the same list also runs $9/$24 and $15/$38 tiers plus a $24 inhaler line, and Walmart’s program terms note that higher dosages cost more and that retail prescriptions must be filled in person, with refills picked up in store. The 300 mcg strength is not on the list at all.
-
Price a transparent mail pharmacy for a 90-day fill. Cost Plus Drugs lists $5.90 to $6.41 for 30 tablets across the strength range, plus $5.25 standard shipping per order. Its published breakdown on the 100 mcg tablet is $0.96 of manufacturing, $0.14 of markup and $5.00 of pharmacy labor, so ordering 90 at a time spreads both the labor fee and the shipping across three months.
-
Ask the manufacturer directly before paying brand prices. If you and your prescriber have a specific reason to stay on brand Synthroid, AbbVie’s own cash program is $29.50 for 30 tablets or $75 for 90 with free shipping, against roughly $160 for 90 at a pharmacy. That single phone call or enrollment is worth about $85 a fill.
-
Run a free discount card if you fill locally. Card prices on levothyroxine move around, so price the exact strength and quantity rather than assuming. Our comparison of GoodRx vs. SingleCare covers how to check both on one prescription and why an online quote can differ from the counter.
-
Do not switch brands casually to save money. Different levothyroxine products are not automatically substitutable in practice, and a switch usually means new lab work. That is a prescriber conversation, not a pharmacy one, and the lab bill can wipe out the savings. Our thyroid test cost guide and blood work cost guide cover what TSH monitoring runs as a cash payer.
-
Budget for the monitoring, not the pills. The prescription is the cheap part of treating hypothyroidism. A free or sliding-scale clinic can handle the visit and refills at little or no cost, and if a lab or hospital bills you more than expected, our guide to negotiating medical bills covers what to do next.
Bottom Line
Budget $4 to $13 a month for generic levothyroxine without insurance, and treat anything above about $25 as a reason to shop rather than a fact about the drug. The strength you take barely matters to the price, so a dose increase is never a reason to accept a large jump.
If you want brand Synthroid, buy it from AbbVie at $29.50 for 30 days or $75 for 90 rather than at a counter for roughly $160 per 90. If you are on Tirosint or Tirosint-SOL, expect $56.75 to $169 for 30 doses and check whether a plain tablet would do the same job before you keep paying it. For the other cheap generics people usually fill alongside this one, see our gabapentin cost guide and lisinopril cost guide, which tell nearly identical pricing stories.
