Prescription Flea Medicine For Dogs Sourced from top veterinary pharmaceutical brands, like Bravecto, Heartgard, & Nexgard, our products are designed to offer fast relief from infestations and protect against future pest invasions.

Our top pick for a prescription topical treatment is Revolution Plus, which treats fleas, ticks, heartworms, roundworms, hookworms, and ear mites. If you're looking for an OTC topical medicine to kill fleas, ticks, and lice, we recommend Frontline Plus for Cats.

After the spot-on application is administered, the ingredients spread over the surface of your cats' fur and sebaceous glands killing fleas within 24 hours and ticks within 48 hours.

Spot-ons and sprays designed to remain on the surface kill fleas when they land on the pet's coat or ingest the product. Some topical products kill fleas by interfering with their nervous system. The fleas can appear active and mobile just before they die.

Consider the following benefits of using monthly flea preventatives on your pet:

• Reduce skin allergies, infections and hot spots. Many pets are allergic to flea saliva, which can trigger allergies, itching, and scratching.
• Prevent tapeworms.
• Prevent tick-borne diseases.
• Prevent flea infestations in your home.

Since pyrethrins, permethroids, and pyrethroids can be dangerous to cats, look for other, safer active ingredients in the flea treatment you choose. Some ingredients to look for include imidacloprid, fipronil, indoxacarb, dinotefuran, spinetoram, fluralaner, spinosad, nitenpyram, lufenuron, methoprene, or pyriproxyfen.

Two common ingredients in flea-and-tick products, permethrin and pyrethrins, are very toxic to cats. Don't put these ingredients on your dog, either, if you also have a cat that could snuggle up with or brush against it.

Position the fur back into place. Taking care not to rub off the treatment with your hand. Make. Sure not to touch your eyes or mouth and wash your hands after application.

You can handle, stroke and cuddle your pet as usual as soon as the application site is dry. In the meantime, treated animals should not be handled and children should not be allowed to play or sleep with them.

Even after medicinally treating your cat, you'll want to comb him with a fine-toothed metal flea comb from head to tail at least once a day. This will skim off adult fleas and their eggs and ease his itching. Then, dip the comb in a mixture of water and liquid dish detergent to kill the fleas.

After administering flea and tick medication to your dog, expect to see at least some dead fleas within 24 hours of treatment. However, it will probably take a few days for the itching to decrease.

Topical preventions have been shown to clear fleas on cats within 12-48 hours, and oral preventions often work within the first 2-4 hours. Never use a flea or tick medication labeled for dogs. They are not interchangeable, and a product made for dogs can make cats extremely sick, and in rare cases it may be fatal.
