Tobramycin is a generic drug. A generic contains an exact copy of the active drug in a brand-name medication. A generic is considered just as safe and effective as the original drug but tends to cost less.

Tobramycin comes in brand-name versions called Bethkis, Kitabis Pak, Tobi, Tobi Podhaler, and Tobrex. To find out how the costs of brand-name versions and generic tobramycin compare, talk with your doctor, pharmacist, or insurance provider.

If you’ve been prescribed tobramycin and are interested in a brand-name version instead, talk with your doctor. They may prefer one version instead of the other. In addition, you’ll need to check with your insurance provider. This is because it may only cover one drug or the other.

Why is there such a cost difference between brand-name drugs and generics?

Years of research and testing are needed to ensure that brand-name drugs are safe and effective. This testing can make the drugs expensive. The manufacturer of a brand-name drug can sell the drug exclusively for up to 20 years. After that, other drugmakers can create generic versions. This competition in the market can lead to lower costs for generics. And because generics have the same active ingredients as brand-name drugs, they don’t need to be studied again. This can also lead to lower generic costs.

Most forms of tobramycin are used only for the short-term treatment of a bacterial infection. But if you’re prescribed tobramycin inhalation solution, it’s possible you may use it long term. In this case, you may be able to lower your costs in the following ways:

Look into getting a 90-day supply of your medication. You may be able to get a 90-day supply of tobramycin inhalation solution if approved by your insurance company. This could reduce your number of trips to the pharmacy and help lower the cost of this dosage form of tobramycin. If you’re interested in getting a 90-day supply of this drug, talk with your doctor, pharmacist, or insurance provider.

Use a mail-order pharmacy to get your medication. Using a mail-order pharmacy might help lower your cost for tobramycin inhalation solution. Plus, you could get your medication without leaving home. Some Medicare plans may help cover the cost of mail-order drugs. You may also be able to get a 90-day supply of the drug through mail order. If you don’t have health insurance, talk with your doctor or pharmacist. They may be able to suggest online pharmacy options that could work for you.
