Yes a dog dewormer that contains only Praziquantel does work. I used it to cure my Tapeworm infection. I bought a bottle of Prazi 34mg each, 5 pills in a bottle. I took 4 pills every 4 hours till I went to bed. After 2 days I felt much relief. I also took diatomaceous earth to ”stratch” the Tapeworms exoskeletons to assist the Prazi's dissolving action. After 2 days I took DE again and a few hours later my last Prazi pill. Im cured so far. I wasted hundreds on Drs that didnt, couldnt and wouldnt help me. And those all those herbal remedies did nothing but make me run around town spending hundreds on crazy ingredients to make useless, for this condition- concoctions.
