Plants and Paragon Medication

Has anyone had experience using a medication called Paragon by Aquatronics 
in a planted tank.  Specifically, I'm interested in the medication's 
affects on the plants.  I'm almost to the point of sacrificing a 125g 
planted tank to get rid of gill flukes in my 8 discus.  I could harvest 
some plants, treat the tank, then bleach and replant if necessary.
