Dosing Schedule

To apply NexGard® COMBO topical solution, use scissors to cut the blister along the dotted line, then pull the lid away. Remove the applicator from the package and hold it upright. Pull back the plunger slightly, then twist and pull off the cap. Part the hair on the midline of the neck, between the base of the skull and the shoulder blades until the skin is visible. Place the tip of the applicator on the skin and apply the entire contents directly onto the skin in one spot. The product should be applied to dry skin on an area where the cat cannot lick it off. If the weight of the cat requires a second application, apply the contents in the same manner as described above in the same location. Wash hands after use with soap and water.
Do not administer orally. Cats may salivate excessively if NexGard® COMBO topical solution is accidentally administered orally or is ingested through licking/grooming the application site (see Target Animal Safety). Esafoxolaner, one of the ingredients in NexGard® COMBO, is a member of the isoxazoline class. This class has been associated with neurologic adverse reactions including tremors, ataxia, and seizures. Seizures have been reported in cats receiving isoxazoline class drugs, even in cats without a history of seizures. Use with caution in cats with a history of seizures or neurologic disorders. The safety of NexGard® COMBO has not been fully evaluated in breeding, pregnant, or lactating cats. The safety of NexGard® COMBO has not been tested in kittens less than 8 weeks of age or weighing less than 1.8 lbs. The most frequently reported adverse reactions include vomiting, application site reactions, and anorexia.
