Hi and welcome to TCS! I searched this site for any threads that discussed Tapex Plus and found none. This product is a broad spectrum wormer and contains 18mg Praziquantel and 73mg Pyrantel Pamoate. It looks to be pretty much the same as Drontal which contains 18.2 mg praziquantel and 72.6 mg pyrantel pamoate. Drontal is one I believe is used quite often.
