Compare cash prices across pharmacies (Script Unlock)

Switch to the generic version
Polymyxin B/Trimethoprim has a generic alternative — Polymyxin B sulfate / Trimethoprim — that contains the identical active ingredient at the same dose. FDA-approved generics undergo the same bioequivalence testing as brand medications. Ask your prescriber if generic Polymyxin B sulfate / Trimethoprim is appropriate.
Buy a 90-day supply instead of 30-day
Pharmacies typically discount 90-day supplies of Polymyxin B/Trimethoprim by 10–20% compared to buying 30-day quantities three times. Fewer dispensing fees, fewer refill trips. Ask your prescriber to write a 90-day prescription with refills.
Check for manufacturer patient assistance
If Polymyxin B/Trimethoprim is a brand-name medication and you meet income thresholds, the manufacturer may offer a Patient Assistance Program (PAP) providing the drug at no cost. Programs typically require prescriber attestation and annual re-enrollment. Note: PAPs usually exclude Medicare patients due to federal anti-kickback rules.
Ask your prescriber about therapeutic alternatives
There may be a clinically similar medication in the same drug class at a lower price. For example, older members of a drug class often cost less than newer options while providing similar clinical outcomes for many patients. Never switch medications without prescriber approval — but a conversation costs nothing.
