Advantix II Vs Vectra 3d


The War of Best Flea Drops Rages On

It seems as if there are a million different types of flea drops available on the market but which one is the best for your dog?

Today we’re going to take a look at two of the top products available only from your veterinarian: Advantix II and Vectra 3D to decide which product is best for your pet.

What Do They Do?

Both products are spot-on treatments that are applied at the base of the neck in order to fight fleas and other biting parasites. They both work for up to 30 days.

The active ingredients in Vectra 3D are:

  • Dinotefuran, a neurotoxin
  • Pyriproxyfen, an insect growth inhibitor
  • Permethrin, a neurotoxin and insect repellant

Vectra claims to kill fleas, ticks, mosquitoes, biting flies, sand flies, lice and mites, excluding mange mites.

The active ingredients in Advantix II are:

  • Imidacloprid, which is a neurotoxin
  • Permethrin
  • Pyriproxyfen

As you can see, the two products share two of their ingredients. Advantix II kills and repels fleas, ticks and mosquitoes, kills lice and repels biting flies.

Side Effects and Warnings

The most important warning attached to both of these products is that permethrin is toxic to cats and can even kill them so if you have cats, you need to keep them away from your dogs until the flea meds are dry. Obviously, you can’t use either of these on cats either.

Advantix II and Vectra 3D share the most common side effect, which is rash, itching, or irritation at the site of administration. If it gets too severe or lasts for more than a day or two, just wash your dog with dish detergent. If it persists after that, you may want to call your vet.

The two flea drops share the exact same rare side effects as well. The ones listed below are extremely uncommon but could happen.

  • Lethargy
  • Hyperactivity
  • Drooling
  • Shaking
  • Poor Coordination
  • Excess vocalization

If your pet exhibits any of these symptoms, you should wash off the medication and contact your veterinarian immediately.

Final Word

Advantix II and Vectra 3D are both recognized as safe to use on your dog but due to the permethrin cannot be used on cats.

They carry equal risks and the only discernible difference is that Vectra 3D claims to kill mites as well. The two different neurotoxins act in essentially the same way and one really isn’t recommended as better than the other.

In this instance, we simply recommend that you choose the product that your vet recommends.
