What is tobramycin and how does it work?

Tobramycin is an FDA-approved aminoglycoside antibiotic that kills certain serious gram-negative bacteria, most notably Pseudomonas aeruginosa. It works by interfering with the bacteria's ability to make the proteins they need to survive. It comes in several very different forms for very different situations:

• Injectable (IV/IM): used in the hospital for serious infections such as bloodstream infection (septicemia), lower respiratory tract infections, serious central nervous system infections including meningitis, intra-abdominal infections, skin, bone and soft-tissue infections, and complicated or recurring urinary tract infections.
• Inhalation solution and powder (TOBI, TOBI Podhaler, Bethkis, Kitabis Pak): used to manage chronic P. aeruginosa lung infection in people with cystic fibrosis.
• Ophthalmic drops (Tobrex): used to treat bacterial conjunctivitis (pink eye) and other external bacterial eye infections.

Like all antibiotics, tobramycin only works against bacteria. It will not help with colds, the flu, or other viral illnesses.

Tobramycin cost and savings without insurance

Tobramycin has been generic for years, so it is generally an affordable antibiotic even if you pay cash. The catch is that pharmacies set their own cash prices, and the difference between the cheapest and the most expensive pharmacy in the same town can be large, especially for the inhalation forms. That is exactly why comparing matters. Rx.com checks tobramycin prices at more than 60,000 pharmacies and shows you a free coupon you can use at the counter, with or without insurance. Enter your ZIP above to see today's price near you.

Some brand-name inhalation products may also have a manufacturer copay or savings program. Teva offers information for its tobramycin products on its official site (tevatobramycin.com); eligibility and terms vary and typically exclude government insurance, so check the manufacturer's own page for current details. For most people filling a generic prescription, comparing pharmacy cash prices with an Rx.com coupon is the simplest way to keep costs down.

Tobramycin vs. related antibiotics and combinations

Tobramycin belongs to the same aminoglycoside family as gentamicin and amikacin; these are chosen based on the specific bacteria, local resistance patterns, and how the drugs are tolerated. For eye infections, the ophthalmic form is often sold as Tobrex, and there is also a combination eye product, TobraDex, that pairs tobramycin with the steroid dexamethasone for infections with inflammation.

For some infections a doctor may instead prescribe a fluoroquinolone such as ciprofloxacin, which is taken by mouth or as drops and covers a different range of bacteria. Only your prescriber can decide which antibiotic and which form fits your infection. Whichever generic you are prescribed, you can compare prices for it on Rx.com.

Safety and what to watch for

Injectable (IV/IM) tobramycin carries an FDA boxed warning because it can affect the kidneys (nephrotoxicity, which is usually reversible) and the hearing and balance nerve (ototoxicity, where hearing loss can be permanent and affect both ears). It can also cause muscle weakness or breathing problems (neuromuscular blockade), particularly when given with anesthetics or muscle relaxants. Because of this, hospital teams monitor kidney function, hearing, and the level of drug in the blood, and they avoid combining it with other kidney- or ear-toxic drugs such as other aminoglycosides, loop diuretics, or vancomycin. Aminoglycosides can harm a developing baby, so tell your provider if you are or may be pregnant.

The inhaled forms mainly act in the lungs but can sometimes cause wheezing (bronchospasm) or ringing in the ears (tinnitus). The eye drops have very little effect on the rest of the body but can cause local irritation or an allergic reaction. This is general information, not medical advice; ask your doctor or pharmacist about your specific situation and report any new hearing changes, dizziness, or reduced urination right away.
