Revolution is the brand name for selemectin, a pesticide aimed specifically at dog or cat fleas. It's made by Pfizer, one of the world's leading pharmaceutical companies for human and pet medications. Revolution is available from a wide variety of places, which can greatly affect the cost. In general, Revolution for dogs costs more than Revolution for cats.
There are two types of Revolution--for dogs and for cats. Cats include kittens over six week old. Packages come in three, six or 12 dosages. Be sure you know if your cat weighs over or under 5 lbs. Cats and kittens under 5 lbs. get one dosage amount that averages $43 in the U.S. Cats over 5 lbs. have a three-dose package that costs the same.
Because of the vast weight differences in dogs, there are several dosage amounts for Revolution for dogs. They also come in packages of three, six or 12. For dogs up to 5 lbs. in weight, the average cost of three doses is $40. For dogs 5 to 10 pounds, the cost is $42. For 10 to 20 pounds, the cost is $44. For dogs 20 to 40, the cost is $46. For dogs 40 to 85 pounds, the cost is $48. For dogs 85 to 130 pounds, the cost is $60.
Revolution is sold through vet clinics and from online pet medical-supply websites. Unlike some other kinds of flea and tick medications, Revolution needs a prescription. So, you have to take your pet to the vet in order to get the prescription. Call your vet to see if an appointment is really necessary, or if you can just pick up a prescription if you want to use an online service. This all adds to the cost of Revolution.
Do not use dog Revolution on cats. This can kill the cat. Using cat Revolution on a dog can also kill the dog or induce seizures in the dog. This is true of all flea medications. Also, using a dose for a small dog on a very large dog will not do much good. There's not enough medication to protect the entire dog.
Unless your pet goes to shows or your particular area is heavily infected with fleas, you can try to save on the cost of Revolution by dosing once every two or three months instead of every month. Pets that remain mostly indoors and rarely interact with strange dogs, cats, rodents or birds will not be as exposed to fleas as a pet who romps in the woods every day. Please talk to your vet before doing this.
Although there are pet medication websites that often advertise Revolution on sale, you will not save very much as compared to buying at the vet's office.
