Indications
Treatment and prevention of flea infestations (Ctenocephalides felis) on cats.
One application prevents flea infestation for one month. It also prevents the multiplication of fleas by inhibiting flea emergence in the environment of the cat for 3 months.
Dose to be administered and administration route
Spot-on use.
Dosage:
The minimum recommended dose is 42.3 mg dinotefuran/kg bodyweight and 4.23 mg pyriproxyfen/kg bodyweight.
The treatment dose range is 42.3 to 705 mg dinotefuran/kg bodyweight (bw) and 4.23 to 70.5 mg pyriproxyfen/kg bodyweight (bw) for cats of 0.6 kg to 10 kg bodyweight.
Care should be taken to apply the veterinary medicinal product only onto intact (undamaged) cat’s skin.
Treatment schedule:
Following a single administration, the veterinary medicinal product will prevent flea infestation for one month and prevent further flea multiplication by inhibiting flea emergence in the environment of the cat for 3 months. The need to re-treat cats which are likely to be re-infested, and the time interval between such treatments, should be based on an assessment by a veterinarian.
How to apply:
Remove the spot-on applicator from the pack.
Step 1: Hold the applicator upright, placing fingers below the larger disk as shown.
Step 2: With the other hand, press downwards on the smaller disk until the 2 disks meet evenly. This will pierce the seal.
Step 3: The cat should be standing or in a comfortable position for easy application. At the base of cat’s head, part the hair until the skin is visible. Apply the veterinary medicinal product slowly with the tip of the applicator on the skin. Avoid superficial application to the cat’s hair.
