Special precautions to be taken by the person administering the veterinary medicinal product to animals
Keep pipettes in the original packaging until ready to use.
Do not eat, drink or smoke while handling the veterinary medicinal product.
The sachet is child-resistant. Keep the product in the sachet until use, in order to prevent children from getting direct access to the product. Used pipettes should be disposed of immediately.
People with known hypersensitivity to indoxacarb should avoid contact with this product.
Local and/or systemic reactions have been observed in some people after exposure. To avoid adverse reactions:
• administer the product in a well-ventilated area;
• do not handle recently treated animals until the application site is dry;
• on the day of treatment, children must not handle treated animals and the animals should not be permitted to sleep with their owners, especially children;
• wash hands immediately after use and wash off any product in contact with the skin immediately with soap and water;
• avoid contact with eyes, as the product may cause moderate eye irritation. If it occurs, the eyes should be rinsed slowly and gently with water.
If symptoms occur, seek medical advice and show the package leaflet to the physician
This product is highly flammable. Keep away from heat, sparks, open flame or other sources of ignition.
In very rare cases, a brief period of hypersalivation may occur if the animal licks the application site immediately after treatment. This is not a sign of intoxication and disappears within some minutes without treatment. Correct application (see section 4.9) will minimise licking of the application site. In very rare cases, application site reactions such as transitory scratching, erythema, alopecia or dermatitis at the application site may occur. These effects will usually resolve without treatment.
The application of the veterinary medicinal product may produce a local, temporary oily appearance or hair clumping at the application site. A dry white residue may be also observed. This is normal and will generally resolve within a couple of days after administration. These changes do not affect the safety or efficacy of the veterinary product.
The frequency of adverse reactions is defined using the following convention:
- very common (more than 1 in 10 animals displaying adverse reaction(s) during the course of one treatment)
- common (more than 1 but less than 10 animals in 100 animals)
- uncommon (more than 1 but less than 10 animals in 1,000 animals )
- rare (more than 1 but less than 10 animals in 10,000 animals)
- very rare (less than 1 animal in 10,000 animals, including isolated reports).

The appropriate combination of
pipettes should be used
Method of administration:
For spot-on use only. Open one sachet and remove the pipette.
Step 1: The animal should be standing for easy application. With one hand, hold pipette in an upright position away from your face and with the other hand, snap tip open by bending it and folding it back on itself.
Step 2: Part the hair until the skin is visible and place pipette tip against the skin between the shoulder blades for dogs. Squeeze pipette firmly applying the entire contents directly to the skin
In larger dogs, the entire contents of the pipette(s) should be applied evenly to two or three or four spots, all located at different application sites along the backline from the shoulder to the base of the tail. Do not apply an excessive amount of solution at any one spot which could cause some of the solution to run off the side of the animal.
Treatment schedule: Following a single administration, the veterinary medicinal product will prevent further flea infestation for at least 4 weeks.
No adverse effects were observed in dogs aged 8 weeks or older when administered 5 times the recommended dose on 8 occasions at 4 weeks intervals or administered 5 times the recommended dose on 6 occasions at 2 weeks intervals.
