Bethkis (Tobramycin) Rx Price Comparison: US vs Canada — Save Up to 10% in the US

Our most recent US pharmacy data shows a low of roughly $2,236.56 for Tobramycin with a standard discount card. That figure moves with dosage and quantity — check the comparison table for the exact combination you need.

Yes — Cost Plus Drugs lists Tobramycin at roughly $2.65 per unit, a published price with no membership card or coupon involved. See the three-price comparison above for how that stacks up against discount-card pharmacies.

We found Canadian pricing for Tobramycin starting near $2.94 per tablet in USD terms. That's before any shipping charge, which the table above breaks out separately.

Drug pricing is set separately in each country through different negotiation, regulatory, and distribution systems, so the same medication can legitimately carry different price tags on either side of the border. In this case, our data shows the US price is actually the lower of the two once a program like Cost Plus Drugs is factored in — the assumption that Canada is always cheaper doesn't hold for every drug.

Your out-of-pocket cost for Bethkis with insurance depends entirely on your specific plan's formulary, deductible, and copay structure. It is recommended to ask your pharmacist to check the price under your insurance and compare it to the price available through a prescription savings card or program. In some cases, the savings card price may be lower than your insurance copay.

Bethkis is a brand-name inhaled antibiotic containing tobramycin. It is specifically indicated to treat lung infections caused by Pseudomonas aeruginosa in people with cystic fibrosis. This bacterium is particularly problematic for those with compromised lungs. Bethkis works by blocking essential protein synthesis in the bacteria. The standard treatment regimen involves inhaling the medication through a PARI LC PLUS Reusable Nebulizer twice daily for 28 days, followed by a 28-day treatment-free period before resuming the cycle. Always consult your doctor or pharmacist for specific dosing instructions.

The most frequently reported side effects of Bethkis involve the respiratory tract and voice, including hoarseness, sore throat, voice changes, difficulty speaking, wheezing, abnormal lung sounds (rales), and lung problems. Other possible effects include nosebleeds and swollen tonsils. You should seek immediate medical attention if you experience signs of an allergic reaction, such as hives, facial swelling, or difficulty breathing.
