Bosentan Manufacturer Assistance Program — Free or Reduced Cost
Bosentan costs approximately $5,500/month at retail. The manufacturer Patient Assistance Program (PAP) can provide Bosentan free or at very low cost for qualifying patients. Script Unlock cash price from $3025 is an immediate alternative if you don't qualify or can't wait the typical 4–8 weeks.
What is the Bosentan patient assistance program?
The Bosentan Patient Assistance Program is a free-drug program run by the medication manufacturer for uninsured and underinsured patients who can't afford Bosentan.
Once enrolled, qualifying patients receive Bosentan 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 $Bosentan users — which the manufacturer wants. There's no catch.
Who qualifies for Bosentan PAP?
Most Bosentan PAP programs share these eligibility criteria. Specific income thresholds and rules vary by manufacturer — always confirm with the program directly:
