Revolution is used in the prevention, control, and treatment of various parasite infections. The active ingredient is selamectin, which interferes with the parasite's nervous system. It is an effective heartworm preventive, killing the immature form of the heartworm (Dirofilaria immitis). It kills adult fleas (Ctenocephalides felis) and prevents flea eggs from hatching for one month. It is also used for the treatment and control of ear mites (Otodectes cynotis) and sarcoptic mange (Sarcoptes scabiei). Revolution is effective in controlling tick infestations due to the American dog tick (Dermacentor variabilis). In cats, Revolution also treats and controls roundworm and hookworm infections.

For the prevention of heartworm disease, Revolution must be applied monthly, preferably on the same date each month. It is recommended (and most manufacturer guarantees require) that Revolution be used year round, although some veterinarians may recommend using it only during the mosquito season. If used seasonally, the first dose must be applied within 30 days of the pet's first exposure to mosquitoes. The last dose must be applied within 30 days after the pet's last exposure to mosquitoes.

To control fleas, apply the first dose one month prior to the expected start of the flea season.

Part the hair on the back of the pet at the base of the neck in front of the shoulder blades. Place the tip of the tube on the skin and squeeze the tube 3-4 times to empty the entire contents on the skin. Do not massage into skin or apply to broken skin. Do not apply when the haircoat is wet.

Revolution will kill the immature heartworms the pet was exposed to in the preceding month. For ear mites and sarcoptic mange, most mites are killed with one treatment, although a second treatment a month later may be required; follow the advice of your veterinarian. To control ticks, the dosage may need to be changed from the heartworm dose of once a month; again follow your veterinarian's recommendations. Most fleas are killed within 36 hours of application. If the pet was already infested with fleas when Revolution was applied, you may see fleas after that period of time as the immature forms of the fleas in the environment hatch.

Talk to your veterinarian about the heartworm testing that is recommended before starting your pet on a heartworm prevention program.

Collies or other herding breeds may have a reaction to selamectin if given over the recommended heartworm prevention dose. If your dog is one of these breeds, and your veterinarian has prescribed Revolution, observe your pet for at least 8 hours after giving the medication for weakness, staggering, dilated pupils, trembling, drooling, or pressing the head against a wall. Contact your veterinarian immediately if you see these signs.

Some intestinal parasites, such as hookworms and roundworms can be spread to people.

Talk to your veterinarian about other measures you can take to prevent your pet from being infected with intestinal worms, and protecting yourself.

Notify your veterinarian of any other medications or supplements your pet is taking, and also if your pet has had any reactions to previous medications.

If a dose is missed and over 30 days have gone by since the last dose, apply Revolution immediately and resume a monthly dosing schedule. Tell your veterinarian that a dose was missed.

Do not use on puppies less than 6 weeks of age or kittens less than 8 weeks of age. Use with caution in sick, weak, or underweight animals. Safe to use on breeding animals and pregnant and nursing females.
