Augmentin Cost Without Insurance: What a Full Course Really Costs in 2026

Augmentin cost without insurance runs about $86 to $95 for a 10-day course of generic amoxicillin/clavulanate 875/125 mg (20 tablets) at retail, and often $15 to $40 with a free discount card. Brand-name Augmentin runs roughly $465 to $901 for 14 tablets. Same molecule, very different receipt.

TL;DR: Key Takeaways

• Price the full course, not the pill: 875/125 mg twice daily for 10 days is 20 tablets.
• Generic amoxicillin/clavulanate is FDA-rated bioequivalent to the brand and costs a fraction of it.
• A quote over roughly $100 for a 10-day adult course usually means brand, not generic.
• For adult sinusitis, plain amoxicillin may do the same job for less. Ask before the script is sent.
• The visit, not the antibiotic, is usually the bigger bill when you are uninsured.

Augmentin cost without insurance swings from about $15 to over $900 for the same 10-day course

Without insurance, a 10-day course of generic amoxicillin/clavulanate 875/125 mg (20 tablets) typically costs about $86 to $95 at retail cash price, and often $15 to $40 with a free discount card. Brand-name Augmentin is the outlier: roughly $465 to $901 for 14 tablets, depending on the pharmacy and the pricing date. The active ingredients are identical.

Compare courses, not tablets. At 875/125 mg twice daily for 10 days you need 20 tablets; at 500/125 mg three times daily you need 30. Before you call around for quotes, check how many days you'll be taking it, because tablet count drives the total more than strength does.

Here is what most pages will not tell you: there is no national price for this drug. Published figures disagree because they price different things. One source quotes $86 for 20 generic tablets and another $95; one quotes $464 for 14 brand tablets and another $901. Different pack sizes, strengths, dosage forms, pharmacies, ZIP codes and data dates produce different numbers, and all of them can be accurate on the day they were pulled.

If you want a sanity floor, CMS publishes the National Average Drug Acquisition Cost, a federal benchmark of what pharmacies actually pay per unit. Every figure here is a cash-pay estimate current as of publication in 2026, and the only price that binds is the one your pharmacy quotes at fill time.

Augmentin is amoxicillin/clavulanate, and for sinusitis you may not need the "clav"

Every amoxicillin clavulanate price you see quoted is an Augmentin price, because that is what Augmentin is: amoxicillin plus clavulanic acid, a beta-lactamase inhibitor that keeps resistant bacteria from destroying the amoxicillin. Two levers move your bill, and both live upstream of any coupon.

The first is brand to generic. The FDA requires an approved generic to deliver the same active ingredient at the same rate and extent, in the same strength, dosage form and route as the brand. It costs less only because generic manufacturers do not repeat the brand's original clinical trials.

The second lever is the clavulanate itself. The IDSA's rhinosinusitis guideline recommends amoxicillin-clavulanate over amoxicillin alone as first-line therapy, but that is a strong recommendation with moderate-quality evidence in children and only a weak recommendation with low-quality evidence in adults. A 2026 IDSA analysis, "Cut the clav?", found treatment failure rates of 3.0% versus 3.1% for amoxicillin alone in acute sinusitis, with more secondary yeast infections and more C. difficile infections in the clavulanate arm. And amoxicillin alone usually costs under $20 without insurance. For a detailed comparison of standalone amoxicillin pricing, see our How Much Is Amoxicillin Without Insurance? guide.

This is a conversation to have with your prescriber before the prescription is written. Do not swap, split or stop an antibiotic that has already been prescribed to you.

If your pharmacy quotes over $100 for a 10-day course, you're being priced on brand

Generic Augmentin cost is the benchmark to judge any quote against, and the rule of thumb is blunt: a standard 10-day adult course should land in the tens of dollars, not the hundreds. A number over roughly $100 means one of three things. You are being priced on the brand, on the wrong pack size, or on a non-tablet form.

The question at the counter is one sentence: "Can you fill this as generic amoxicillin/clavulanate, and what is the cash price?" Pharmacies substitute by default in most cases, but a prescriber who marked the script "dispense as written" or brand-only blocks that, and undoing it means a call back to the office. Ask for substitution to be permitted before the script is sent.

There is no broadly available manufacturer copay card for Augmentin from GSK, and price-guide publishers report finding no manufacturer promotions. Your savings here is the generic, not a program. Cash prices for the identical generic still differ between pharmacies, so a second quote is worth one phone call.

A free discount card beats a brand-name coupon almost every time

An Augmentin coupon is worth having, but it is the third lever, not the first. Free discount cards worth comparing include GoodRx, SingleCare and Optum Perks, the last of which reports savings of up to about $36 per fill (Medical News Today, 2026). A card replaces the cash price at the register, is free to sign up for, and has to be shown before you pay, not after.

The catch: an 80% discount on a $465 brand fill still costs more than a $20 generic. Fix the drug first, then apply the card. Prices differ by pharmacy and ZIP code even for the same card, so pull quotes from two or three pharmacies before you commit. Warehouse and membership pharmacies typically post lower cash prices than large chains, and in the US the pharmacy counter is generally accessible without a club membership, though it is worth confirming with the store. Any coupon price published anywhere, including here, is a snapshot rather than a guarantee.

For kids, bottle size, not strength, decides what the liquid costs

Augmentin liquid suspension price is set by the bottle, which is why parents get blindsided. Brand 125 mg/31.25 mg per 5 mL suspension runs roughly $580 to $870 depending on pack size (Drugs.com, 2026); the generic suspension costs a fraction of that, and you should ask for it by name.

Suspension comes in fixed bottle volumes, commonly 75 mL, 100 mL and 150 mL. The cost driver is total millilitres, which is your child's weight-based dose multiplied by doses per day multiplied by days, not the concentration printed on the label. Ask the pharmacist to calculate total mL for the full prescribed course before filling, so you neither run short nor pay for a second bottle you barely touch. Reconstituted suspension is refrigerated and discarded after 10 days, so leftover volume is money spent, not medicine banked. The FDA label advises giving each dose at the start of a meal to reduce stomach upset.

How much is Augmentin once you add the cost of getting the prescription?

How much is Augmentin in total? For most uninsured adults it is roughly $20 to $95 for the drug plus whatever the prescriber visit costs, and the visit is usually the larger number. Amoxicillin/clavulanate is prescription-only in the US, so there is no version of this where you skip that step. It is worth knowing what an urgent care visit costs without insurance before you walk in.

One lower-cost route is August's $39 online urgent care visit, where a US-licensed clinician evaluates your symptoms and decides whether an antibiotic is appropriate. Be clear on the limits: a telehealth visit cannot perform an in-person exam, order imaging on the spot, or run a throat or urine culture, and the clinician will not prescribe an antibiotic when one is not indicated. If you do get a prescription, ask for it to be sent to the pharmacy you already price-checked, with generic substitution allowed.

The most expensive mistake is rationing the course to save money

Halving doses to stretch a bottle, stopping the day you feel better, or finishing an old partial supply are all cost-driven decisions that cost more later. An undertreated infection means a second visit and a second prescription, often a pricier one.

Call 911 or your local emergency line or go to an ER immediately if:

• You have difficulty breathing or swallowing, wheezing, or swelling of the face, throat, tongue, lips or eyes.
• Your skin is peeling, blistering or shedding.
• Your skin or eyes turn yellow, or your urine turns dark.
• You develop watery or bloody diarrhea with cramps or fever, including up to two or more months after finishing the antibiotic, which can signal C. difficile colitis.
• You suspect an overdose, or notice cloudy or bloody urine or a sharp drop in urination. Poison Control is 1-800-222-1222.

Book a visit if:

• You are not improving after 48 to 72 hours of treatment.
• You develop a mild rash with no breathing trouble.
• You have diarrhea that is persistent but not bloody.
• Your symptoms return after the course ends.

Talk to a physician if:

• You have any penicillin or cephalosporin allergy.
• You have had antibiotic-associated liver injury before.
• You have kidney disease. The FDA label says the 875 mg tablet should not be used when GFR is under 30 mL/min.
• You are pregnant or breastfeeding, or taking other medications.
