Can a common cholesterol pill flush out 'forever chemicals' from veterans' bodies?
NCT ID NCT07592858
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a drug called colesevelam, normally used for high cholesterol, can help lower levels of PFAS (often called 'forever chemicals') in the blood of veterans. About 50 veterans with high PFAS levels will receive either the drug or a placebo for a period, and researchers will measure changes in their blood and cholesterol. The goal is to find a safe way to reduce these chemicals and improve health.
