Augmentin XR has been hard to find at pharmacies. Learn why this antibiotic faces supply issues in 2026 and what you can do to fill your prescription.
You get a prescription for Augmentin XR, head to the pharmacy, and hear the dreaded words: "We don't have that in stock right now." You try another pharmacy. Same story. It's frustrating, especially when you're dealing with a sinus infection or pneumonia and need your medication now.
The truth is, Augmentin XR has faced on-and-off supply challenges for several years. If you've been struggling to find it, this article explains exactly why — and what you can do about it.
Augmentin XR is an extended-release antibiotic that combines two active ingredients: Amoxicillin and Clavulanate Potassium. It belongs to the penicillin class of antibiotics. The "XR" stands for extended-release, which means the medication releases slowly in your body to maintain higher levels of amoxicillin over time.
This makes Augmentin XR particularly effective against bacteria that have developed some resistance to standard penicillin antibiotics — including certain strains of Streptococcus pneumoniae that cause sinus infections and pneumonia.
Augmentin XR is FDA-approved to treat:
The generic version is called Amoxicillin/Clavulanate Potassium Extended-Release, and you might also hear it referred to as Amox-Clav XR or high-dose Augmentin. To learn more about how this medication works, check out our guide on how Augmentin XR works.
There are several reasons why you might be having trouble finding Augmentin XR at your local pharmacy. Here are the main factors:
GlaxoSmithKline (GSK), the original manufacturer of Augmentin XR, has scaled back or discontinued the brand-name product in certain markets. This means pharmacies that used to stock the brand-name version may no longer carry it. Generic versions are still manufactured, but not every pharmacy keeps extended-release formulations on their shelves.
Amoxicillin-based antibiotics have faced significant supply chain disruptions since the 2022-2023 respiratory illness season. The FDA has documented seven shortage reports for amoxicillin products and two specifically for Augmentin XR. These shortages are caused by a combination of increased demand during cold and flu season, limited domestic manufacturing capacity, and global raw material supply constraints.
Unlike regular Augmentin (which comes in multiple strengths and forms), Augmentin XR is only available as a 1000mg/62.5mg extended-release tablet. Many pharmacies stock standard Augmentin but don't keep the extended-release version on hand because it's prescribed less frequently. Your pharmacy may need to special-order it, which can take a day or two.
Augmentin XR is primarily prescribed for sinus infections and pneumonia — conditions that surge during fall and winter. When respiratory illness season hits, demand for antibiotics spikes and supply can't always keep up. If you're trying to fill a prescription during peak season, you're more likely to encounter stock-outs.
Don't panic. There are several practical steps you can take to get your medication:
Instead of calling pharmacy after pharmacy, use Medfinder to check which pharmacies near you have Augmentin XR in stock. It saves you time and frustration by showing real-time availability information.
Large chain pharmacies often run out of less common medications first. Independent and compounding pharmacies may have better access to specialty formulations like Augmentin XR, or they may be able to order it more quickly through their distributors.
If you absolutely cannot find Augmentin XR, your doctor may be able to prescribe an alternative antibiotic. Options like Levofloxacin, Moxifloxacin, Cefdinir, or Doxycycline can treat similar infections, though each has its own pros and cons. Read more in our article on alternatives to Augmentin XR.
If the pharmacy doesn't have brand-name Augmentin XR, ask specifically about generic Amoxicillin/Clavulanate ER. The generic is therapeutically equivalent and typically much cheaper — often $30 to $60 with a coupon card compared to $80 to $250 for brand-name. Check out our guide to saving money on Augmentin XR for specific discount options.
Save yourself a wasted trip. Call the pharmacy before heading over and ask them to check stock for Amoxicillin/Clavulanate ER 1000mg/62.5mg tablets. If they don't have it, ask when they expect their next shipment. For more tips, see our full guide on how to check if a pharmacy has Augmentin XR in stock.
There's actually some good news. In 2025, the FDA approved a new domestic antibiotic manufacturer — USAntibiotics — under the National Priority Voucher Pilot Program specifically to strengthen domestic manufacturing capacity for essential antibiotics like amoxicillin and Augmentin XR. This approval is designed to help stabilize supply and reduce reliance on overseas manufacturing.
While it may take time for new manufacturing capacity to fully ramp up, this is a meaningful step toward making antibiotics like Augmentin XR more consistently available.
If you're struggling to find Augmentin XR, you're dealing with a real and widespread problem — not just bad luck at your pharmacy. Supply chain issues, seasonal demand, and the discontinuation of the brand-name product have all made this medication harder to get.
The most important thing is to not delay your treatment. Use tools like Medfinder to locate the medication, try independent pharmacies, and talk to your doctor about alternatives if needed. For the latest on supply issues, check our Augmentin XR shortage update for 2026.
