Is Tobramycin still in shortage in 2026? Get the latest update on availability, costs, and what patients can do to find Tobramycin in stock.
If you or a loved one relies on Tobramycin — whether for eye infections, serious bacterial infections, or cystic fibrosis — you've probably noticed that finding it hasn't always been easy. Tobramycin supply has been inconsistent for several years now, and patients deserve to know where things stand in 2026.
In this article, we'll break down the current shortage situation, explain why Tobramycin has been hard to find, tell you what it costs today, and share the best strategies for getting your prescription filled.
The short answer: it depends on the formulation.
Tobramycin injection has been on and off the ASHP (American Society of Health-System Pharmacists) drug shortage list for years. The injectable form — used in hospitals for serious infections like sepsis, pneumonia, and complicated UTIs — has been most affected. Some manufacturers have discontinued certain vial sizes, and the remaining producers (Pfizer, Fresenius Kabi, Hikma) can't always keep up with demand.
Tobramycin ophthalmic drops and ointment (generic and Tobrex brand) are generally more available, but individual pharmacies may still run out periodically due to local supply chain issues.
Inhaled Tobramycin (TOBI, TOBI Podhaler, Bethkis, Kitabis Pak) has experienced occasional disruptions. Because these products serve a smaller but highly dependent population of cystic fibrosis patients, even minor production issues can create significant availability gaps.
Several factors have contributed to Tobramycin supply issues:
Akorn Pharmaceuticals discontinued their Tobramycin injection product (40 mg/mL, 30 mL vial), removing a key source from the market. Fewer manufacturers means less competition and less production capacity to absorb demand spikes.
Injectable antibiotics require strict sterile manufacturing conditions. Production shutdowns for quality control, equipment upgrades, or FDA compliance can take months to resolve, creating supply gaps.
Tobramycin — like other aminoglycosides — is derived from fermentation processes using Streptomyces bacteria. Disruptions in raw material supply or active pharmaceutical ingredient (API) production can cascade through the supply chain.
Even when Tobramycin is being manufactured, distributors sometimes allocate limited supplies to hospitals first, leaving retail and specialty pharmacies with less stock for outpatient prescriptions.

Here are the most effective strategies:
Medfinder shows you which pharmacies near you currently have Tobramycin available. It's free and takes seconds — much faster than calling pharmacies one by one.
Independent pharmacies often have access to different distributors and may have Tobramycin when the big chains don't. For inhaled Tobramycin, specialty pharmacies (like Accredo or CVS Specialty) that focus on CF medications typically maintain dedicated stock.
Your pharmacist can check stock across other locations in their network, place a special order, or contact your doctor to suggest an available alternative. They're one of your best resources during a shortage.
Your insurer's pharmacy helpline can help locate in-network pharmacies with stock and may authorize emergency supplies or temporary out-of-network fills if needed.

The Tobramycin shortage situation in 2026 is not one-size-fits-all. Injectable forms remain the most affected, while eye drops are generally easier to find. Inhaled formulations for CF fall somewhere in between — usually available but requiring proactive planning.
The most important thing you can do: don't wait until you're out. Plan your refills early, use Medfinder to find pharmacies with stock, explore financial assistance if cost is a barrier, and keep your prescriber in the loop so they can adjust your treatment plan if needed.
