Use with caution in dogs with a history of seizures (see Adverse Reactions).
In a well-controlled US field study, which included a total of 333 households and 615
treated dogs (415 administered afoxolaner; 200 administered active control), no serious
adverse reactions were observed with NEXGARD.
Over the 90-day study period, all observations of potential adverse reactions were
recorded. The most frequent reactions reported at an incidence of > 1% within any of the
three months of observations are presented in the following table. The most frequently
reported adverse reaction was vomiting. The occurrence of vomiting was generally selflimiting
and of short duration and tended to decrease with subsequent doses in both
groups. Five treated dogs experienced anorexia during the study, and two of those dogs
experienced anorexia with the first dose but not subsequent doses.
