According to WebMD, owners, under the guidance of a veterinarian, can give dogs deworming agents with the brand names of Cestex, Droncit, Drontal Plus, Vercom Paste and Telmintic to destroy tapeworms within their intestines. WebMD adds that preventative measures against fleas and lice can guard against reinfestation, as these pests are carriers of the worm.
According to Dr. Wendy C. Brooks for the Veterinary Information Network, Droncit and Drontal Plus are actually the same medication: a drug with the generic name of praziquantel. Drontal Plus combines praziquantel with another drug, febantel, in an oral tablet. Droncit is praziquantel alone in tablet form. The U.S. Food and Drug Administration lists Vercom Paste as having the same combination of drugs as Drontal Plus, but Vercom is an edible paste, not a pill.
The FDA describes Cestex as being specialized for tapeworms rather than a general dewormer as with the above drugs. PetEducation.com from Foster and Smith describes Telmintic as being only useful for tapeworms that use mammals as carriers, rather than the more common flea tapeworm.
