Why Is Moxifloxacin So Hard to Find? [Explained for 2026]

If you've been prescribed moxifloxacin and your pharmacy told you it's out of stock, you're not imagining things. This fluoroquinolone antibiotic — sold under the brand name Avelox before generic versions took over — has been intermittently hard to fill at certain pharmacies since late 2023. The American Society of Health-System Pharmacists (ASHP) added moxifloxacin tablets to its official drug shortage database in December 2023, and the listing was still active as of December 2025.

The good news: moxifloxacin is not in the same category as critically unavailable drugs like certain chemotherapy agents or rare injectables. Multiple generic manufacturers still produce it, and it can usually be found with some effort. This guide explains exactly what's happening and what you can do about it.

Is Moxifloxacin Actually in Shortage?

Yes — at least for certain manufacturers. The ASHP shortage bulletin, last updated December 15, 2025, specifically identifies

Teva's 400 mg moxifloxacin tablets (30-count bottles, NDC 00093-7387-56)

as the primary affected product. Teva has not provided a reason for the shortage. Aurobindo — another major generic manufacturer — has refused to provide availability information to ASHP, which leaves patients and pharmacies in the dark about their supply outlook.

However, not every manufacturer is affected. Major Pharmaceuticals and Rising Pharmaceuticals both have moxifloxacin tablets available. This means the drug shortage is manufacturer-specific rather than a wholesale disappearance from the market — but it does create real pharmacy-level gaps when a store primarily stocks Teva or Aurobindo products.

Why Is Moxifloxacin Hard to Find at Some Pharmacies?

There are several reasons a pharmacy might not have moxifloxacin on the shelf even when it's technically available somewhere in the supply chain:

Manufacturer shortages create regional gaps. Pharmacies that rely on Teva or Aurobindo as their primary supplier may be unable to restock until those manufacturers resolve their supply issues.

Wholesaler allocation limits. During a shortage, drug wholesalers like McKesson, AmerisourceBergen, and Cardinal Health may impose purchase limits per pharmacy, restricting how much stock any single location can order.

Low inventory turnover. Moxifloxacin is a short-course antibiotic (typically 5-10 days), so pharmacies don't maintain as large a standing stock as they do for chronic medications taken daily.

Chain pharmacy formulary preferences. Large pharmacy chains often contract with specific generic manufacturers. If that manufacturer is short, all stores in the chain may be affected simultaneously.

Which Moxifloxacin Formulations Are Most Affected?

Not all moxifloxacin formulations are equally affected by the current shortage:

Oral tablets (400 mg): This is the most affected formulation, with specific NDC numbers from Teva listed in the ASHP shortage bulletin. Check availability at multiple pharmacies, as other generics may be in stock.

IV solution (400 mg/250 mL): Hospital-use IV formulations have also seen intermittent availability issues, though this primarily affects inpatient settings rather than retail patients.

Ophthalmic solution (0.5% — Vigamox, Moxeza, generic): Eye drop formulations are generally more available than tablets, though prices vary widely between generic and brand versions.

What Can You Do Right Now If You Can't Find Moxifloxacin?

If your pharmacy says moxifloxacin is out of stock, here are your most practical options:

Use medfinder. medfinder calls pharmacies near you to check which ones have your exact medication in stock — so you don't have to spend hours on hold.

Ask your pharmacy for a special order. Pharmacies can often order specific NDC numbers from different wholesalers. Ask if they can source from a manufacturer other than Teva.

Try independent pharmacies. Independent and compounding pharmacies sometimes have more flexibility in their supplier relationships and may stock different manufacturers than the large chains.

Ask your doctor about alternatives. If moxifloxacin is genuinely unavailable, there are effective fluoroquinolone and non-fluoroquinolone alternatives for most infections it treats. Never switch on your own — always talk to your prescriber first.

Are There Good Alternatives to Moxifloxacin?

Yes. Moxifloxacin is a 4th-generation fluoroquinolone, and there are other antibiotics in the same class — as well as alternatives in different classes — that can treat many of the same infections. Your prescriber will choose based on your specific infection, allergy history, and local resistance patterns.

Levofloxacin (Levaquin): The most commonly prescribed respiratory fluoroquinolone, widely available in generic form. Once-daily dosing, similar spectrum for respiratory infections.

Ciprofloxacin (Cipro): The most widely used fluoroquinolone in the US, with strong gram-negative coverage. Better for certain GI and urinary infections.

Azithromycin (Z-Pak): A macrolide antibiotic and common first-line choice for mild community-acquired pneumonia and sinusitis in appropriate patients.

Doxycycline: A tetracycline antibiotic used for respiratory infections, skin infections, and more. Widely available and inexpensive.

How medfinder Helps When Your Pharmacy Is Out of Moxifloxacin

Calling pharmacies one by one is time-consuming and frustrating — especially when you're dealing with an infection and need antibiotics quickly. medfinder does the work for you: you provide your medication, dosage, and zip code, and medfinder contacts pharmacies in your area to find out which ones can fill your prescription. Results are texted directly to you.

The Bottom Line

Moxifloxacin is experiencing a real but manufacturer-specific shortage, primarily affecting Teva's 400 mg tablets. The drug is not gone from the market — it can still be found from other manufacturers including Major and Rising. The key is knowing where to look. Use medfinder to check availability near you, or ask your pharmacist to source from a different NDC. And if all else fails, talk to your doctor about the right alternative for your infection.
