Colistin Manufacturer Assistance Program — Free or Reduced Cost
Colistin costs approximately $300/month at retail. The manufacturer Patient Assistance Program (PAP) can provide Colistin free or at very low cost for qualifying patients. Script Unlock cash price from $138 is an immediate alternative if you don't qualify or can't wait the typical 4–8 weeks.
What is the Colistin patient assistance program?
The Colistin Patient Assistance Program is a free-drug program run by the medication manufacturer for uninsured and underinsured patients who can't afford Colistin.
Once enrolled, qualifying patients receive Colistin at $0 cost — typically shipped quarterly to your prescriber's office or your local pharmacy. Enrollment lasts 12 months and must be renewed annually.
PAPs are funded by the manufacturer (not a charity, not the government). They exist partly for goodwill and partly because covered patients become long-term $Colistin users — which the manufacturer wants. There's no catch.
Who qualifies for Colistin PAP?
Most Colistin PAP programs share these eligibility criteria. Specific income thresholds and rules vary by manufacturer — always confirm with the program directly:
