Topical flea and heartworm medicine: Revolution
Topical Revolution is a simple monthly topical parasiticide for many external and internal parasites (fleas and heartworms), and has been increasing in use in recent years because of its many possible potential applications. Unlike many of its competitors like Frontline or Advantage, topical Revolution does require a written prescription from a veterinarian. I have found it most useful in controlling fleas, ticks and ear mites in dogs and cats.
Veterinary dermatologists often are now frequently using it every 2 weeks for a total of 3 treatments in many itchy dogs to treat any possible hidden scabies mange mites, which are often difficult to find on even multiple skin scrapings at the vet office. Topical use in cats has also helped in protecting cats from the intestinal parasites roundworms and hookworms. While it’s labeled for efficacy against heartworms, in my opinion I still stick with the tried and tested prescription monthly heartworm preventative medications such as Heartgard. This is because in my experience over the years I have seen a few rare pets test positive for heartworms when relying exclusively on Revolution for heartworm prevention.
I often get questions about safety issues around people, but as long as you allow the product to completely dry, which occurs up to 2 hours after applying, there seems to be no risk to humans. Also, animal guardians can be free to bathe their pets anytime after this two hour mark, as this product is labeled as waterproof. While supposedly being safe to use in pregnant animals, I personally never like or recommend applying topical pesticides to pregnant animals.
