Is Lifeguard all-in-one treatment safe to use with plants?

I have a freshwater aquarium that's been set up for a few months. It has a betta and 2 tetras (yes, I know the tetras need more playmates, but I'm waiting on getting a bigger tank set up before doing that). Anyway, I bought this product for my betta, who has a mild case of fin rot. My tank has java fern. Will the meds kill my java fern? What do I do with the java fern to keep it alive if I must take it out?
