When you hear “PFAS,” you probably think of nonstick cookware, waterproof jackets, or contaminated drinking water. You probably don’t think of the prescription sitting in your medicine cabinet. Yet fluorinated compounds classified as per- and polyfluoroalkyl substances (PFAS) are built into a surprisingly wide range of approved pharmaceuticals, often not because they’re essential to how those medicines treat disease, but because they make the drug easier to formulate.
If fluorine serves the manufacturer’s design goals more than the patient’s therapeutic needs, then every PFAS-containing medicine that passes through your body and into the water supply deserves a harder look, particularly now that researchers have mapped out whether effective alternatives already exist. An analysis published in Sustainable Chemistry and Pharmacy took on exactly that question, and the answer should change how we think about drug design going forward.1
PFAS-Free Drug Alternatives Already Exist Across Nearly Every Medical Category
For the study, researchers investigated whether PFAS-containing medicines are truly necessary or whether practical alternatives already exist.2 They reviewed approved active pharmaceutical ingredients (APIs), the part of a medicine that produces its therapeutic effect, and identified 111 PFAS-containing medicines used in humans and 28 used in veterinary medicine.3
