Active Ingredients
Cheristin™ Topical for cats should be applied as directed by your veterinarian. This medication should be administered at every 30 day intervals.
Remove one applicator tube from blister package. Hold the applicator in an upright position. Press cap down until it clicks (indicating the tube has been punctured). Hold upright and remove cap. Check to be sure there is an opening in the tip of the tube.
Part the hair on the neck at the base of the head until skin is visible.  Place the tip of the tube directly above the skin and squeeze the tube 2-4 times to expel the contents of the tube onto the skin. Avoid contact with skin, eyes, or clothing. Wash hands thoroughly with soap and water after handling the medication.
Missed Doses
Give the dose as soon as possible. If it is almost time for the next dose, skip the missed dose, and continue with the regular schedule. Do not give 2 doses at once.
Side Effects
Monitor your cat after application. Side effects may include reactions at the site of application such as hair loss, hair change (greasy, clumping or matting), or redness, inflammation and itching.
Other side effects such as inactivity, vomiting, and inappetance have also been reported. If these or any other side effects occur, consult your veterinarian.
