Praziquantel 600 mg tablet belongs to the class of medicines called anthelmintics used to treat infections due to Schistosoma and liver fluke. PRAZIQUANTEL kills the parasites by paralyzing the worms. This causes the worms to release their hold on the blood vessels so they can be removed from the body. Thereby, PRAZIQUANTEL helps treat schistosomiasis and liver fluke infections. Praziquantel 600 mg tablet may also be used to treat other worm infections, including tapeworm infection.
