Droncit ® Feline Cestocide Tablets are sized for easy oral administration to either adult cats or kittens. The tablets may be crumbled and mixed with the feed.


Droncit ® Feline Cestocide Tablets are indicated for the removal of the following feline cestodes: Dipylidium caninum and Taenia taeniaeformis .


There are no known contraindications to the use of praziquantel in cats.


Droncit ® (praziquantel) is absorbed, metabolized in the liver and excreted in the bile. Upon entering the digestive tract from the bile, cestocidal activity is exhibited. 1
Following exposure to praziquantel, the tapeworm loses its ability to resist digestion by the mammalian host. Because of this, whole tapeworms, including the scolex, are very rarely passed after administration of praziquantel. In many instances only disintegrated and partially digested pieces of tapeworms will be seen in the stool. The majority of tapeworms killed are digested and are not found in the feces.


Droncit ® Feline Cestocide Tablets may be administered directly per os or crumbled and mixed with the feed. The recommended dosage of praziquantel varies according to body weight. Smaller animals require a relatively larger dosage because of their higher metabolic rate. The optimum dose for each individual animal will be achieved by utilizing the following dosage schedule:
Cats and Kittens*
4 pounds and under 1/2 tablet
5-11 pounds 1 tablet
Over 11 pounds 1 1/2 tablets
*Not intended for use in kittens less than 6 weeks of age.
FASTING: The recommended dosage of praziquantel is not affected by the presence or absence of food in the gastrointestinal tract, therefore, FASTING IS NEITHER NECESSARY NOR RECOMMENDED.
RETREATMENT: For those animals maintained on premises where reinfections are likely to occur, clients should be instructed in the steps necessary to prevent reinfection; otherwise, retreatment may be necessary. This is especially true in cases of Dipylidium caninum infections where reinfection is almost certain to occur if fleas are not removed from the animal and its environment.


The safety index has been derived from controlled safety evaluations, clinical trials and prior approved use in foreign countries.
Dosages of 5 times the labeled rate at 14 day intervals to cats as youngas 5 1/2 weeks did not produce clinical signs of toxicity. No significant clinical chemistry, hematological, or histopathological changes occurred. Symptoms of gross overdosage include vomition, salivation, diarrhea and depression.


Droncit ® (praziquantel) has been tested in breeding and pregnant cats. No adverse effects were noted.
