Treatment of Cystic Fibrosis with Unexplained Prolonged Cough Lasting More Than 2 Weeks

This protocol applies to individuals with cystic fibrosis — including those with CRMS/CFSPID — who present with an unexplained prolonged cough lasting more than 2 weeks and in whom no readily identifiable cause has been found.

Evidence-based guidance supports considering antibiotic therapy in selected patients presenting with this scenario.

The complete structured regimen — including selection criteria, agent class, and clinical decision points — is available in the full protocol.
