How much does polymyxin B cost, and what affects the price?
Pricing for polymyxin B varies widely based on the exact product (for example, injectable vs. inhaled use), strength/concentration, package size, and whether it is brand-name or an authorized generic. Availability can also change by market and supply conditions, which can push prices up or down.
Because “polymyxin B” can refer to different formulations and strengths, the most reliable way to estimate current cost is to check the exact National Drug Code (NDC) or the specific manufacturer and vial/box size you need.

Is polymyxin B a generic, and does that change the price?
Polymyxin B is generally treated as an older, off-patent antimicrobial in many markets, which usually means multiple manufacturers or generics may be available at different price points. Even with generics, the final price you pay can still differ because of:
- pharmacy/contract pricing,
- shipping and hospital purchasing arrangements,
- dose rounding based on vial size.
What if I’m a patient—how can I reduce out-of-pocket cost?
If you’re paying out of pocket or through insurance, ask the pharmacy or prescriber’s office about:
- whether an equivalent generic/NDC is available,
- using the nearest in-stock vial size to minimize waste,
- whether prior authorization is required (some insurers require it for specific antibiotics or formulations).
If you share the formulation (injectable or other), strength (e.g., units per vial), and your country (or whether you’re using a specific pharmacy system), I can help you narrow down what to look for when comparing prices.
