Product Overview

Revolution offers total protection from parasites. It is a topically-applied liquid medication that prevents heartworms and fleas. It also treats and controls American dog ticks, sarcoptic mange, and ear mites. See the Allivet Heartworm Comparison chart to find which heartworm prevention is best for your pet.

For use in dogs.

Features of Revolution:

Works to treat sarcoptic mange
Effectively controls infestations of American dog ticks (Dermacentor variabilis)
Controls and treats ear mites
Works to kill fleas (Ctenocephalides felis) and prevent hatching of eggs
Prevents parasites and heartworm disease

After you topically apply Revolution, it begins to work by entering the bloodstream through the skin. It then works to prevent parasitic worms and heartworm disease. Selamectin, the active ingredient, stays in the bloodstream and tissue of the dog, maintaining prevention. Selamectin kills adult fleas and American dog ticks, prevents hatching of flea eggs, and works to treat sarcoptic mange and ear mites.

Revolution is typically well-tolerated. Studies have shown less than 1% of dogs experience digestive upset.

The active ingredient in Revolution is selamectin, which interferes with the parasite's nervous system.

Contact your closest animal hospital in case of adverse reaction.

Before administration, your dog will require a heartworm test to rule out existing infections. Infected dogs require heartworm treatment prior to starting on Revolution.
Flammable - keep away from heat. Keep out of reach of children and pets.

Available in 3 or 6 month supply in color coded boxes according to your dog's weight.

Pink: Dogs weighing up to 5 lbs
Purple: Dogs weighing between 5-10 lbs
Brown: Dogs weighing between 11-20 lbs
Red: Dogs weighing between 21-40 lbs
Green: Dogs weighing between 41-85 lbs

Zoetis

Revolution is an FDA-approved drug. It is only available with a veterinarian's prescription, and it is not an EPA-registered pesticide. While it is applied topically, Revolution is a broad-spectrum, systemically-acting parasiticide with a well-defined safety profile. This couples with incredible efficacy, working to protect your dog from many different parasites.

For the prevention of heartworm disease, Revolution must be administered monthly, preferably on the same date each month. If a dose is missed and over 30 days have gone by since the last dose, give Revolution immediately and resume the monthly dosing schedule.

Revolution may be given year round or only during the mosquito season. If given seasonally, the first dose must be given within 30 days of the dog's first exposure to mosquitoes. The last dose must be given within 30 days after the dog's last exposure to mosquitoes.

We recommend you test your pet for heartworm infection before starting a preventive program.

Reminder stickers are included to place on your calendar for each of the months following the date of the first dose.

Switching Heartworm Preventives: If Revolution replaces another type of heartworm preventive, the first dose must be given within 30 days after the last dose of the previous product.

Flea Control: For the prevention and control of flea infestations, Revolution should be administered at monthly intervals throughout the flea season, starting one month before fleas become active.

Ear Mite Treatment: For the treatment of ear mite (O. cynotis) infestations, Revolution should be administered once as a single topical dose. A second monthly dose may be required in some animals. Monthly use of Revolution will control any subsequent ear mite infestations. Cleansing of the infested ears is recommended to remove the debris.

Sarcoptic Mange Treatment for Dogs: For the treatment of sarcoptic mange (S. scabiei) in dogs, Revolution should be administered once as a single topical dose. A second monthly dose may be required in some dogs. Monthly use of Revolution will control any subsequent sarcoptic mange mite infestations.

Tick Control for Dogs: For the control of tick (Dermacentor variabilis) infestations in dogs, Revolution should be administered on a monthly basis. In heavy tick infestations, complete efficacy may not be achieved after the first dose. In these cases, one additional dose may be administered two weeks after the previous dose, with monthly dosing continued thereafter.

Puppies: (6 weeks of age or older)

Up to 5 lbs Apply contents of 1 tube once a month (Mauve Box)

Dogs:

5.1-10 lbs Apply contents of 1 tube once a month (Purple Box)

10.1-20 lbs Apply contents of 1 tube once a month (Brown Box)

20.1-40 lbs Apply contents of 1 tube once a month (Red Box)

40.1-85 lbs Apply contents of 1 tube once a month (Teal Box)

85.1-130 lbs Apply contents of 1 tube once a month (Plum Box)

Over 130 lbs Use the appropriate combination of tubes

Selamectin, the active ingredient in REVOLUTION, is a macrocyclic lactone compound. These compounds effectively prevent the development of adult heartworms when administered to dogs and cats within one month of exposure to infective (L3) Dirofilaria immitis larvae. Efficacy of macrocyclic lactones decreases below 100% in dogs, however, if first administered >2 months after exposure to infective larvae. Thus, in heartworm endemic regions, delaying initiation of heartworm prevention using REVOLUTION beyond 2 months of first exposure to infective larvae (e.g., starting puppies and kittens at >8 weeks of age), or gaps of >2 months in the administration of REVOLUTION during periods of heartworm transmission, increases the risk of the animal acquiring heartworms. Animals with unknown heartworm history that test negative for heartworms prior to the initiation of REVOLUTION may be harboring pre-patent infections at the time REVOLUTION was started.

Testing such animals 3-4 months after initiation of REVOLUTION would be necessary to confirm their negative heartworm status.

Easy fix for fleas.

Revolution is a very easy way to prevent flea infestations and the resulting inflamation caused by their bites. Happy dog equals happy owner.

I have always used Revolution on all my dogs because one of them refused to take pills, and I rarely find ticks and never had fleas using revoution.
