Tired of Calling Pharmacies to Find Tobramycin?

You've got the prescription. Now you need to find a pharmacy that actually has Tobramycin on the shelf. Depending on which form you need — eye drops, injection, or inhaled solution — that can range from simple to surprisingly difficult.

Generic Tobramycin eye drops are widely available at most pharmacies. But inhaled Tobramycin (TOBI, Bethkis, Kitabis Pak, or generic nebulizer solution) is a specialty product that not every pharmacy stocks. And Tobramycin injection has seen intermittent shortages in recent years.

The good news? You don't have to call pharmacy after pharmacy to find out who has it. Here's how to check stock without picking up the phone.

Why Tobramycin Can Be Hard to Find

Not all Tobramycin formulations are created equal when it comes to availability:

• Eye drops (generic, 0.3%) — Generally easy to find. Most chain and independent pharmacies carry them.
• Injection (40 mg/mL vials) — Has been on and off the ASHP drug shortage list since 2015. Some vial sizes were discontinued (Akorn 30 mL vial), and remaining manufacturers sometimes can't keep up with demand.
• Inhalation solution (300 mg/5 mL) — A high-cost specialty product with limited manufacturers. Brand TOBI and generics can have supply disruptions, especially during periods of high demand among cystic fibrosis patients.
• TOBI Podhaler — A specialty inhaled powder available only through select pharmacies.

How to Check Without Calling

1. Use Medfinder

Medfinder is designed specifically for this problem. Search for Tobramycin, enter your location, and see which pharmacies near you have it available. It covers both retail and specialty pharmacies, making it especially useful for inhaled formulations that aren't stocked everywhere.

Medfinder also shows pricing information, so you can compare costs while you're checking availability — two birds, one stone.

2. Pharmacy Apps and Websites

Most major pharmacy chains let you check prescription status or transfer prescriptions online:

• CVS — Use the CVS app or cvs.com to check drug availability at specific locations. You can also transfer your prescription digitally.
• Walgreens — The Walgreens app lets you manage prescriptions and check status. You can send your prescription to a specific store.
• Walmart — Walmart's pharmacy app shows prescription status and allows transfers between locations.
• Rite Aid — Similar functionality through their app and website.

Keep in mind that these apps show whether your prescription is ready, not necessarily whether the drug is in stock for new prescriptions. But if you transfer your Rx and it gets filled quickly, that's a good sign.

3. GoodRx

GoodRx shows you pricing at pharmacies near you, and generally only displays pharmacies that stock the medication. While it's not a direct stock-checker, if a pharmacy appears in GoodRx results for Tobramycin, they likely carry it or can order it quickly. You can also use GoodRx coupons to save money on your prescription.

4. Send Your Prescription Digitally

Ask your doctor to e-prescribe Tobramycin to a specific pharmacy. If the pharmacy doesn't have it in stock, they'll typically contact you within a few hours. This saves you a trip and lets the pharmacy check their inventory in the background.

5. Specialty Pharmacy Portals

For inhaled Tobramycin (TOBI, Bethkis, Kitabis Pak), your insurance may require a specialty pharmacy. Common specialty pharmacies include:

• Accredo
• CVS Specialty
• Optum Specialty
• AllianceRx Walgreens Specialty

These pharmacies typically handle the entire process — checking stock, coordinating with your insurance for prior authorization, and shipping directly to your home. Your CF care team can usually connect you with the right specialty pharmacy.

If You Prefer to Call

Sometimes a quick phone call is the fastest route. Here are tips to make it efficient:

• Have your prescription details ready — drug name, strength, formulation (eye drops vs. inhalation vs. injection), and quantity.
• Call during off-peak hours — Early morning (right when the pharmacy opens) or mid-afternoon tends to be less busy than lunchtime or evening.
• Ask if they can order it — If the pharmacy doesn't have Tobramycin in stock, ask if they can order it and how long it would take. Many pharmacies can get common generics within 24 hours.
• Ask about nearby locations — Chain pharmacies can often check inventory at other stores in their system.

Once You Find It

You've located a pharmacy with Tobramycin in stock. Here's what to do next:

Transfer Your Prescription If Needed

If your prescription was sent to a different pharmacy, most pharmacies can handle a transfer with a quick phone call between pharmacists. You can also ask your doctor's office to send a new prescription to the pharmacy that has it.

Check the Price Before You Pick Up

Tobramycin costs vary widely by formulation:

• Generic eye drops: $4–$10 with a coupon
• Injection vials: $4–$5 with a coupon
• Inhaled solution (generic): $2,500–$4,000+
• Brand TOBI or TOBI Podhaler: $8,000–$10,000+ per cycle

For the expensive inhaled forms, make sure your insurance is set up and any copay assistance programs are applied before filling.

Don't Wait Too Long

If a pharmacy has Tobramycin in stock — especially the injectable form during a shortage — don't delay picking it up. Inventory can change quickly, particularly for medications with known supply issues.

Set Up Auto-Refills

If you take inhaled Tobramycin on a recurring 28-day cycle, ask your pharmacy about auto-refills or recurring delivery. This prevents last-minute scrambles each cycle and gives the pharmacy time to order ahead.

What If No Pharmacy Near You Has It?

If you can't find Tobramycin locally:

• Ask your doctor about alternatives. There may be substitute medications that are more readily available.
• Try a mail-order pharmacy. Specialty and mail-order pharmacies often have better access to supply chains for hard-to-find drugs.
• Contact the manufacturer. Novartis (TOBI) and other manufacturers sometimes have distribution support programs.
• Check Medfinder. Medfinder searches broadly and may surface options you haven't considered.

Final Thoughts

For generic Tobramycin eye drops, finding a pharmacy is usually straightforward. For inhaled Tobramycin or injection forms, it takes a bit more effort — but tools like Medfinder, pharmacy apps, and specialty pharmacy networks make it much easier than calling around blindly.

Start with Medfinder to check availability near you, and remember to compare prices and apply coupons before you fill. Your time — and your wallet — will thank you.
