VECTRA^® 3D combines three active ingredients—Dinotefuran, Pyriproxyfen, and Permethrin—to deliver broad-spectrum protection against fleas, ticks, and other external parasites. This triple-action formula kills on contact and repels parasites before they can bite.

Once parasites land on your treated dog, they’re immediately exposed to the active ingredients through the skin and hair. The more they move, the faster they absorb the formula—and the sooner they’re affected.

Permethrin overstimulates sensors in the ticks legs, forcing them to crawl off the dog without biting.

Fleas suffer a rapid disruption in feeding: Within 5 minutes, feeding is significantly reduced. The combined action of Dinotefuran and Permethrin knocks fleas down quickly, causing them to fall off and die—with no chance of recovery.

No. Do not use VECTRA^® 3D on cats, or any other animal.

No. VECTRA^® 3D kills parasites when they come into contact with your pet’s fur.

No, only apply VECTRA^® 3D once in a 30-day period. It is not necessary for more frequent applications – VECTRA^® 3D provides powerful protection against fleas and ticks for a full month.

Yes. The sooner a tick is removed, the lower the chance of it transmitting harmful pathogens to your dog. Always use a proper tick removal tool to ensure safe and effective extraction.

Make sure to remove the entire tick, including the mouthparts embedded in the skin. After removal, dispose of the tick safely—do not crush it with your fingers. Prompt and careful removal is an important step in protecting your dog’s health.

Ask your veterinarian for advice.

Yes. VECTRA ^® 3D is proven to protect your dog for a full month against other major external parasites such as mosquitoes and biting flies.

After topical application, the active ingredients in VECTRA® 3D spread (translocate) from the application site to cover your dog’s entire body within a few hours—and remain effective for a full month.

Dinotefuran is partially absorbed through the skin, resulting in some systemic exposure. However, this absorption is not essential for the product’s effectiveness.

Pyriproxyfen may also be absorbed through the skin to some extent.

Permethrin remains on the skin and hair. In pharmacokinetic studies, no measurable levels were detected in the bloodstream, confirming that it is not systemically absorbed.

To be at risk, your cat needs to ingest or be in contact with VECTRA^® 3D. This can occur if your cat grooms a treated dog and if the application site is not dry yet. To prevent oral exposure of your cat to VECTRA^® 3D, we recommend keeping treated dogs away from cats after treatment until the application site is dry. Cats should not be allowed to groom dogs at the application site until the product has dried. Seek veterinary advice immediately if this occurs.

Immature stages of fleas are hidden in the environment. Inside the house, they are mainly located where the pet sleeps. Flea eggs fall off the animal and develop into larvae. Flea larvae avoid light and live on flea dirt.

They move in random directions but not more than 30-50cm from where the eggs are dropped. Pyriproxyfen, is a highly potent insect growth regulator: it is active at a very low concentration. It disseminates from the treated dog (hairs, skin debris, dust, etc.) and disrupts the development of the immature stages of the fleas. This kills immature fleas, thus preventing emergence of new adults. As demonstrated (Bouhsira et al., 2012), it also sterilizes adult female fleas that are exposed to treated dogs, which prevents egg laying.

No, there are no known interactions.

Yes. VECTRA^® 3D remains effective after repeated combing of dogs. However, to reduce your own exposure to the actives, it is recommended not to brush or comb your dog until the application site is dry.

Do not worry. VECTRA^® 3D has been shown to be safe when ingested at up to 5 times the maximum dose on young dogs. However, to optimize the duration of efficacy of VECTRA^® 3D, we recommend you to distract your dog after administration, while VECTRA^® 3D dries.

Yes. VECTRA ^®3D remains effective against fleas and ticks for up to 4 weeks, even if your dog swims (up to once per week) or is bathed (up to two times during the treatment period).

For optimal efficacy and environmental protection, it’s recommended to avoid bathing or immersing your dog in water until the application site is completely dry, this may take several hours and depends on temperature and air exposure.

In controlled studies, the first bath was given 48 hours after application and repeated weekly without any loss of effectiveness.

To help protect aquatic life, it is advised to prevent treated dogs from entering natural water sources (rivers, streams, lakes, or the sea) for 48 hours after application.

We recommend applying VECTRA^® 3D in the evening or before taking your dog for a walk.
After application, the product begins to spread across the skin, which may cause mild, unusual sensations. If your dog is calm, distracted, or asleep during this time, they’ll likely feel more comfortable.
Applying in the evening also allows the product to dry overnight, ensuring optimal effectiveness.

Clinical studies show that VECTRA ^® 3D starts working quickly to protect your dog from parasites:

Fleas: Feeding is reduced within 5 minutes, and fleas are killed within the first few hours—as early as 2 hours in previously treated dogs, and within 6 hours in untreated, infested dogs.

Ticks: VECTRA ^® 3D becomes effective against ticks 48 hours after application.

Flying Insects: Repellent action against mosquitoes and stable flies begins 24 hours after administration.

Yes. Immature stages of ticks are more susceptible to active ingredients than adult forms. They are easier to kill.

VECTRA ^® 3D contains the Insect Growth Regulator pyriproxyfen. It makes VECTRA ^® 3D truly effective against all immature stages of fleas for up to 1 month after administration.

VECTRA^® 3D can be used on puppies as young as 7 weeks of age or > 1.5kg BW.

VECTRA ^® 3D is strictly contraindicated for cats. Due to their unique physiology and inability to metabolize permethrin, exposure to VECTRA ^® 3D can cause serious harm.
Do not use on cats.
If accidentally applied or ingested by a cat (e.g., through grooming a recently treated dog), seek immediate veterinary attention.
VECTRA® 3D is also not recommended for animals with known hypersensitivity to any of its active ingredients or excipients.
Always follow usage instructions carefully to ensure the safety and well-being of all pets in your household.

VECTRA^® 3D can stain some susceptible fabrics and other materials. We recommend administering VECTRA^® 3D outside or in a room away from susceptible surfaces. You should wait until the application site is dry before allowing your dog to come into contact with susceptible materials or surfaces. Make sure that your dog does not shake after administration. If VECTRA^® 3D does come into contact with delicate materials then use an absorbent cloth to remove as much of the product as possible before cleaning the surface appropriately.

If a cat is accidentally treated with VECTRA ^® 3D, or comes into contact with it from a recently treated dog:

Bathe the cat immediately using dish soap to remove any residual product.

Dry the cat thoroughly and help maintain normal body temperature.

Seek veterinary advice immediately.

If in the eyes, hold eye open and rinse slowly and gently with water for 15 to 20 minutes. Remove contact lenses. Contact your doctor for treatment advice.

If swallowed, call a doctor immediately for treatment advice.

If on the skin, take off contaminated clothes. Rinse the skin immediately with plenty of water for 15 to 20 minutes. Call a doctor immediately for treatment advice.
