Having trouble finding Cefdinir at your pharmacy? Learn why this common antibiotic is hard to find in 2026 and what you can do to get your prescription filled.
If you or your child has been prescribed Cefdinir and your pharmacist told you it's out of stock, you're not alone. Across the country, patients are showing up at pharmacies only to learn that this widely prescribed antibiotic isn't available. It's frustrating — especially when you're dealing with an infection and need treatment fast.
In this article, we'll explain what Cefdinir is, why it's been so difficult to find, and what steps you can take to get your prescription filled.
Cefdinir is a third-generation cephalosporin antibiotic used to treat a variety of bacterial infections. It was originally sold under the brand name Omnicef, which has since been discontinued. Today, Cefdinir is only available as a generic medication.
Doctors commonly prescribe Cefdinir for:
It comes in 300 mg capsules and oral suspension (liquid) forms, making it a popular choice for both adults and children. To learn more about this medication, see our full guide: What Is Cefdinir? Uses, Dosage, and What You Need to Know.
There are several reasons why Cefdinir has become difficult to locate at pharmacies. Here are the main factors:
As of late 2025 and into early 2026, Cefdinir is listed on the ASHP (American Society of Health-System Pharmacists) drug shortage list. Major manufacturer Teva has had both the 250 mg/5 mL oral suspension and 300 mg capsules on back order. Other generic manufacturers have also experienced supply constraints.

Many generic medications, including Cefdinir, rely on a global supply chain for raw ingredients (called active pharmaceutical ingredients, or APIs). Disruptions at manufacturing plants overseas, shipping delays, and quality control issues can all slow production and limit the amount of Cefdinir that reaches U.S. pharmacies.
Cefdinir is frequently prescribed during cold and flu season when bacterial infections like sinusitis, ear infections, and bronchitis are more common. When demand surges — especially for the pediatric liquid suspension — pharmacies can run out quickly. This seasonal pattern has made the shortage worse in winter months.
Since the brand-name Omnicef was discontinued, only a handful of generic companies produce Cefdinir. When even one of these manufacturers experiences a production issue, the overall supply drops significantly. With fewer backup sources, any disruption has an outsized impact on availability.
If your pharmacy is out of Cefdinir, don't panic. There are several practical steps you can take:

Big chain pharmacies often run out first because they serve the most patients. Independent pharmacies may have different suppliers and smaller customer bases, which means they might still have Cefdinir in stock. Compounding pharmacies can sometimes prepare custom formulations as well.
If you truly can't find Cefdinir anywhere, your doctor may be able to switch you to a similar antibiotic. Options in the same class include Cephalexin, Cefuroxime, Cefpodoxime, or even Amoxicillin depending on your infection. Learn more: Alternatives to Cefdinir If You Can't Fill Your Prescription.
Some pharmacies can place a special order for Cefdinir through their wholesaler. It may take a day or two to arrive, but if your infection isn't urgent, this can be a viable option. Ask your pharmacist if they can check with their distributor.
Cefdinir requires a prescription, so you can't buy it over the counter. However, some online pharmacies and mail-order services may have it in stock when local pharmacies don't. Telehealth services can also prescribe Cefdinir if you don't yet have a prescription — see How to Find a Doctor Who Can Prescribe Cefdinir Near You.
