Post-Approval Experience: 
Although not all adverse reactions are reported, based on voluntary post-approval reporting, transient ataxia has been reported following the administration of Drontal Tablets for Cats and Kittens.
A  total of 93 cats with naturally acquired parasite infections were included in two well-controlled laboratory studies to establish the efficacy of Drontal Tablets.  In addition, 85 cats and kittens of various sizes, ages and breeds were included in clinical field studies conducted at six veterinary clinics at different geographic locations throughout the United States.  Data indicate 98% of the cats were completely cleared of parasite infections within 7 days of treatment.  These studies demonstrated Drontal Tablets are safe and efficacious for the removal of the parasite species indicated on the label when used as directed.
Cats treated with 10 times the highest recommended Drontal Tablet dosage during safety studies showed signs of vomition and salivation without other adverse effects.  Eighty-three of 85 cats treated with the recommended dosages of Drontal Tablets in a clinical field study did not exhibit any drug related side effects.  A temporary loss of appetite was reported for one cat and transient loose stools were observed in a second cat.
