Drontal® is recommended for the treatment and control of all gastrointestinal worms in dogs, including roundworm, hookworm, whipworm, and tapeworm (including hydatid tapeworm), and controls the shedding of Giardia cysts. Does not control heartworm. Dosage: each tablet treats 3kg of body weight - suitable for small dogs and puppies. Active constituents (per tablet): 15mg Praziquantel, 14.9mg Febantel, 75mg Pyrantel Embonate. Directions: Dose every 3 months, or at the start of every season, to control roundworms, hookworms, whipworms, and tapeworms. In hydatid tapeworm areas, treat every 6 weeks.
