Augmentin XR Doesn't Have to Break the Bank

You've been prescribed Augmentin XR for a sinus infection or pneumonia, and you're wondering what it's going to cost. If you don't have insurance — or if your insurance has a high deductible — the price tag can feel daunting.

Here's the reality: brand-name Augmentin XR can cost $80 to $250 for a standard 20-tablet course without insurance. But with the right tools and strategies, you can bring that cost down dramatically — sometimes to as little as $30 or less.

This guide walks you through every option for saving money on Augmentin XR in 2026, from coupon cards to patient assistance programs.

What Does Augmentin XR Cost Without Insurance?

Let's start with the numbers. A typical course of Augmentin XR is 20 tablets (two tablets twice daily for 5-10 days). Here's what you might pay without insurance:

• Brand-name Augmentin XR (where available): $80 to $250
• Generic Amoxicillin/Clavulanate ER (no coupon): $60 to $150
• Generic with a coupon card: $30 to $60

The wide price range depends on your pharmacy. Large chain pharmacies like CVS and Walgreens tend to charge more at retail price than warehouse pharmacies like Costco or discount options like Walmart.

Key takeaway: Always ask for the generic version. Generic Amoxicillin/Clavulanate ER 1000mg/62.5mg is the exact same medication as brand-name Augmentin XR at a fraction of the cost.

Coupon and Discount Cards: Your Best First Move

Free prescription coupon cards are the easiest way to save on Augmentin XR. They work even if you have insurance — just compare the coupon price to your copay and use whichever is lower.

GoodRx

GoodRx is the most widely known coupon platform. It shows prices at pharmacies near you and provides a free coupon you can show at the counter or use with your prescription.

• Typical savings: Up to 80% off retail price
• Augmentin XR generic price with GoodRx: typically $30 to $55 for 20 tablets
• Accepted at most major pharmacies including CVS, Walgreens, Walmart, Kroger, and Costco

SingleCare

SingleCare is another popular option. Prices can sometimes beat GoodRx depending on the pharmacy.

• Generic Augmentin/Amoxicillin-Clavulanate prices as low as $10.84 for 20 tablets of the standard formulation
• Extended-release formulation pricing varies — always check current prices
• Free to use, no registration required

RxSaver

RxSaver compares prices across pharmacies and provides coupons similar to GoodRx. It's worth checking because prices can vary between platforms.

Other Coupon Options

Additional coupon programs to check:

• Optum Perks — good for pharmacy comparison shopping
• BuzzRx — accepted at over 60,000 pharmacies
• America's Pharmacy — competitive pricing for generics
• ScriptSave WellRx — widely accepted discount card

Pro tip: Check prices on at least 2-3 different coupon platforms before filling your prescription. Prices vary by pharmacy and platform, and spending 5 minutes comparing can save you $20 or more.

Patient Assistance Programs

If you're uninsured or underinsured and struggling to afford your medication, patient assistance programs (PAPs) can help:

GSK Patient Assistance Foundation

GlaxoSmithKline (the original manufacturer of Augmentin XR) runs a patient assistance program through GSKForYou that provides certain GSK medications at no cost to eligible patients. Eligibility typically requires:

• No prescription drug coverage
• Household income below a certain threshold (typically 300% of the Federal Poverty Level)
• U.S. residency

Apply at gskforyou.com or call GSK's patient support line. Note: Since the brand-name product is discontinued in many markets, this program may have limited applicability for Augmentin XR specifically.

NeedyMeds

NeedyMeds (needymeds.org) is a nonprofit that maintains a comprehensive database of patient assistance programs, discount drug programs, and generic drug savings opportunities. Search for Amoxicillin/Clavulanate to find current programs.

RxAssist

RxAssist (rxassist.org) is another searchable database of patient assistance programs maintained by Volunteers in Health Care. It can help you find both manufacturer programs and independent charitable assistance.

RxHope

RxHope (rxhope.com) connects patients with manufacturer-sponsored assistance programs and can help with the application process.

Other Ways to Save on Augmentin XR

Warehouse Pharmacies

Costco pharmacies consistently offer some of the lowest cash prices for generic medications — and you don't need a Costco membership to use their pharmacy. Sam's Club pharmacy also offers competitive pricing.

Grocery Store Pharmacies

Pharmacies inside grocery chains like Kroger, H-E-B, Publix, and Meijer often run their own discount generic programs. Some offer select antibiotics at reduced prices or even free. Call your local grocery pharmacy to ask about their generic antibiotic pricing.

Walmart $4 Prescription Program

Walmart offers select generic medications for $4 for a 30-day supply. While Augmentin XR may not be on the $4 list, standard Amoxicillin often is, and Walmart's overall pricing for generic antibiotics tends to be competitive. It's worth checking their current pricing.

Mail-Order Pharmacies

If you have insurance, your plan's preferred mail-order pharmacy may offer the lowest copay. Even without insurance, mail-order options like Amazon Pharmacy and Cost Plus Drugs (costplusdrugs.com) offer transparent generic pricing that can be competitive with coupon-card prices.

Ask Your Doctor for Samples

Some doctor's offices keep antibiotic samples on hand. While sample availability for Augmentin XR is limited (especially with the brand discontinuation), it's worth asking — even a few days of samples can bridge the gap while you fill your prescription.

Using Insurance Effectively

If you have health insurance, here's how to maximize your coverage:

• Check your formulary: Generic Amoxicillin/Clavulanate ER is typically covered as a Tier 2 preferred generic on most insurance plans, with copays of $5 to $25.
• Compare copay vs. coupon: Sometimes a coupon card gives you a better price than your insurance copay, especially if you have a high-deductible plan. Always compare both options.
• Prior authorization: Brand-name Augmentin XR may require prior authorization if your insurance covers it at all. The generic usually doesn't.
• Medicare Part D: The generic is generally covered under Part D with a low copay.

Quick Savings Checklist

Before filling your Augmentin XR prescription, run through this checklist:

1. Ask the pharmacist for the generic version (Amoxicillin/Clavulanate ER 1000mg/62.5mg)
2. Check prices on GoodRx, SingleCare, and RxSaver — use the lowest one
3. Compare the coupon price to your insurance copay — use whichever is cheaper
4. Consider filling at Costco, Walmart, or a grocery store pharmacy for lower base prices
5. If you're uninsured, check NeedyMeds, RxAssist, and GSKForYou for assistance programs

Final Thoughts

No one should skip their antibiotic treatment because of cost. Augmentin XR is available as an affordable generic, and with coupon cards, patient assistance programs, and smart pharmacy choices, most patients can fill their prescription for $30 to $60 — or even less.
