I took a phamacology class in my master's program with the Nurse Practitioner students. The NP teaching the class told us of a story of a young (50's) man living in a nursing home with severe liver disease - turns out, it was from the (much advertised to the public) presciption oral medication used to treat nailbed fungus. (read the precautions, it is one of the risks) And after you finish the treatment (hopefully without liver damage) the fungal infection can still come back. In my book, that's not a risk worth taking! My motto is, even if there is only a slight risk of a complication, if you're the one it happens to, it's 100% for you. Tokie
