Polymyxin b trimethoprim coupon?

I can help, but I need one clarification: are you looking for a coupon/discount for a specific drug product (for example, “polymyxin B/trimethoprim ophthalmic drops” or “polymyxin B/trimethoprim topical ointment”) and what country are you in (US, Canada, etc.)?

Polymyxin B + trimethoprim is sold under different brand/generic names depending on the form (eye drops vs. skin/ear). If you tell me:
1) the exact product name (or whether it’s eye/ear/skin),
2) the strength and form (drops, ointment, etc.), and
3) your location,

…I can point you to the most likely coupon options (manufacturer savings, pharmacy discount programs, and relevant pricing resources).
