In well-controlled clinical studies, Revolution was used safely in dogs and cats receiving other veterinary products such as vaccines, anthelmintics, antiparasitics, antibiotics, steroids, collars, shampoos and dips.Tell your veterinarian about all medicines you have given your dog or cat in the past, and any medicines that you are planning to use with Revolution. This should include other medicines that you can get without a prescription. Your veterinarian may want to check that all of your dog's or cat's medicines can be given together.
