Gentamicin Shortage Update: What Patients Need to Know in 2026

If you or a family member takes gentamicin and you have been hearing about drug shortages affecting antibiotics, you may be wondering: is there a gentamicin shortage right now? This updated 2026 guide gives you the current status, explains why supply problems can occur with this medication, and tells you exactly what to do if you cannot find it at your pharmacy.

Gentamicin Shortage Status in 2026: The Bottom Line

As of 2026, gentamicin does not have an active entry on the FDA's national drug shortage database. This is good news. It means that at a national supply level, manufacturers are generally meeting demand for this medication.

However, localized availability issues can and do occur. Individual pharmacies, hospital systems, or geographic regions may experience temporary back-orders or stock-outs for specific formulations or vial sizes. This is not the same as a nationwide shortage but can feel just as frustrating for the patient who needs the medication.

Which Gentamicin Formulations Are Most at Risk?

Not all gentamicin formulations face equal supply risk:

Injectable gentamicin (IV/IM vials): Highest risk. Sterile injectable drugs are the category most often affected by FDA-tracked shortages. Specific concentrations (10 mg/mL vs. 40 mg/mL) and vial sizes can run short independently.

Ophthalmic gentamicin (Gentak drops/ointment): Low risk for most patients. These formulations are stocked at most retail pharmacies and are generally readily available.

Topical gentamicin cream/ointment (0.1%): Moderate risk. Availability varies by pharmacy and region. Some pharmacies carry limited quantities.

A Brief History of Gentamicin Supply Disruptions

Gentamicin has appeared on ASHP (American Society of Health-System Pharmacists) shortage reports and the FDA shortage database multiple times over the past two decades, primarily affecting the injectable formulation. The causes have been typical of sterile injectables: manufacturing quality issues at specific plants, raw material delays, and production capacity constraints when demand spikes.

The U.S. GAO reported that as of July 2024, there were 102 drug shortages being tracked by the FDA, and that shortages have been lasting longer since the COVID-19 pandemic. Sterile injectable drugs continue to be disproportionately affected. Gentamicin, as a sterile injectable, sits in this vulnerable category even during periods of normal supply.

Why Does Gentamicin Face Recurring Supply Challenges?

Several structural factors make gentamicin — like many older generic injectable antibiotics — vulnerable to supply disruptions:

Limited manufacturers: The number of companies making sterile injectable gentamicin in the US is small. A quality event at even one facility can reduce national supply significantly.

Price pressure: Generic drug pricing pressure means margins on gentamicin are thin. Manufacturers have little financial incentive to invest in extra capacity or maintain large buffer stocks.

Complex sterile manufacturing: Making injectable drugs requires specialized facilities, sterility testing, and regulatory compliance. Unlike making an oral tablet, scaling up injectable production quickly is not feasible.

What Should You Do If Your Pharmacy Is Out of Gentamicin?

Here are immediate steps to take if your pharmacy cannot fill your gentamicin prescription:

Use medfinder.com. medfinder calls pharmacies near you to find which ones have your medication in stock. Enter your medication, strength, and ZIP code at medfinder.com and receive results by text.

Call nearby pharmacies. Ask specifically for the gentamicin formulation, strength, and quantity you need. Different pharmacies use different wholesalers and may have stock the others don't.

Contact your prescriber. Explain the situation. They may be able to switch you to an equivalent alternative or write a new prescription for a different formulation.

Check with a compounding pharmacy. Compounding pharmacies can prepare custom formulations when commercial products are unavailable. This may require a specific prescription from your doctor.

Monitoring the Shortage Going Forward

You can monitor the current status of gentamicin and other drugs at the FDA Drug Shortage Database (fda.gov/drugs/drug-shortages) and the ASHP Drug Shortage Resource Center. These resources are updated regularly when manufacturers report supply issues. For practical help finding gentamicin near you in the meantime, our guide on
