I can't imagine it cures it, but maybe it's worth trying. Let us know if you get results.
I'd try the 12-hour formula. Plain old generic guaifenesin doesn't last very long, certainly not long enough to cure anything. I have used the 12-hour to help me get rid of secretions that dry up and cause infections in the winter.
