Where it appears
The PolyGuard composition panel lists nitrofural alongside several other actives, including a separate nitrofurantoin line.
What cannot be inferred
A formulation warning covers the labelled blend and does not attribute the response to one active. The similarly named nitrofurantoin product Focus has a different panel.
What to capture
Keep the nitrofural and nitrofurantoin rows separate, including units and percentages. Note which one is actually printed on each bottle.
