Vivaldis Vi-Fi Forte (Fipronil 0.25% w/v) Tick & Flea Control Spray for Dogs and Cats (100ml)

Active Composition & Mode of Action

• Active Ingredient: Fipronil IP 0.25% w/v.

• Formulation Base: Non-alcoholic, gentle aqueous-emulsion base.

• Therapeutic Class: Phenylpyrazole Ectoparasiticide.

• Mechanism: Fipronil selectively blocks the gamma-aminobutyric acid (GABA)-gated and glutamate-gated chloride channels in the central nervous systems of invertebrates. By halting the normal inhibitory chloride influx, it triggers uncontrolled neural firing, paralysis, and death of the parasite. Because mammalian GABA receptors differ structurally, Fipronil offers a wide margin of safety for pets when used topically.

Step-by-Step Directions for Use

1. Prepare the Coat: Brush the coat to remove knots. Apply in a well-ventilated area or outdoors.

2. Apply Against Hair Growth: Hold the bottle 10 to 15 cm away from the body. Ruffle the hair backwards and spray directly against the natural lay of the coat to ensure the mist reaches the skin surface.

3. Full-Body Application: Spray evenly across the neck, back, chest, flanks, underbelly, legs, and between the toes.

4. Facial Application: For the head and muzzle, do not spray directly toward the face. Spray onto a gloved hand or soft cloth and gently wipe around the neck, outer ears, and forehead—avoiding direct contact with eyes, nose, and mouth.

5. Air-Dry Naturally: Allow the coat to dry naturally. Do not towel-dry, blow-dry, or rinse off.

6. Prevent Licking: Supervise your pet or fit an Elizabethan collar for 30 to 45 minutes until the coat is completely dry. In multi-pet households, keep pets separated until all coats are dry.

7. The 48-Hour Water Rule: Avoid bathing or swimming for at least 48 hours before and 48 hours after application to preserve the natural sebaceous oil layer needed for distribution.
