The dosage chart for NexGard Combo

 

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.

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.
