Seeing as I wrote the sticky on epsom salt, allow me to correct both of you.
While epsom salt can be used as a purgative agent for conditions such as constipation, it is NOT a deworming agent, and should not be used as one. It's role in the sticky was that of an anti-parasite treatment, and a very specific one at that - designed to treat one of the most common internal parasites in the hobby, Spironucleus vortens, aka hexamita. And it is not in any way shape or form harsh on a fish. It's one of, if not the safest treatment in the hobby. Even safer than regular aquarium salt.
As far as worms, PraziPro aka Praziquantel is an is an anthelmintic cestodicide which is basically only effective at treating tapeworms, flatworms, & flukes. It contains <5% praziquantel by weight, and is designed specifically to be used as a dewormer, not to treat internal (or external) parasites such as flagellates, flukes, etc.
For nematodes (round worms) you're better off treating with levamisole as per the directions in the following link.

The author of that paper linked to above, Dr. Roy Yanong, is an Associate Professor and Extension Veterinarian, Program in Fisheries and Aquatic Sciences, University of Florida, Tropical Aquaculture Laboratory.
An excellent read on Levamisole, how it works, and how to effectively use it to treat round worms.
