Full information about Comfortis


Comfortis (spinosad) is an oral flea medication for dogs and cats. Its fast-acting formula starts killing fleas in 30 minutes—even adult fleas! Each chewable beef-flavoured tablet offers full flea protection by killing existing fleas and preventing future infestation for one month. Speak to your veterinarian about the dosage requirements of your pet.

Fleas do not just isolate themselves on your pet’s skin. An infestation not only affects your beloved cat or dog, but also you, your children, and your household. Flea bites can make your pet’s life miserable. Common signs of a flea infestation include excessive scratching, small droppings present in their fur, hair loss, and hot spots. By the time you notice these symptoms, your pet may be heavily infested. Make an appointment with your veterinarian and ask about Comfortis flea medication.

Now you can buy Comfortis at North Drugstore and get all the care your household medication needs under one roof. Order Comfortis or a Comfortis generic alternative today and save big.

Why Pet Owners Choose Comfortis

Comfortis is the #1 prescribed oral flea medication because it's easy to administer and is highly effective. Unlike drops, flea collars, or even pills, Comfortis’ delicious beef-flavoured exterior makes it easy to administer your pet’s dosage just like any other treat, and there’s no mess involved. Simply give them one chewable tablet every month for continued protection against fleas.

Another reason families choose Comfortis for their pets is that they don’t have to isolate them for any period of time. It’s the most hassle-free way to give your pet lasting protection. Your pet won’t have to miss out on any play time while they wait for Comfortis to “kick in.”

How to Administer Comfortis

Be sure to read product label for complete instructions and to ask your veterinarian before administering dose. Comfortis is safe to use on cats of 14 weeks or two pounds and dogs of 14 weeks or 3.3 pounds. Make sure you’ve selected the appropriate dosage of spinosad for your pet’s weight range.

To administer, simply treat your dog with the chewable beef-flavoured tablet once a month to kill fleas and prevent further infestation. To ensure continued protection, give your pet Comfortis at the same time every month.

How it Works

Inside each chewable tablet is a powerful, yet completely pet-safe chemical called spinosad, which was originally designed as a crop insecticide. As your pet digests their Comfortis tablet, the spinosad works its way through the bloodstream and targets the flea’s immune system, eventually killing it. Your pet is completely safe from spinosad’s effects and will soon be enjoying a flea-free existence in just 30 minutes.

Spinosad is an environmentally responsible insecticide that was awarded the Presidential Green Chemistry Challenge Award in 1999 from the U.S. Environmental Protection Agency.

Ask Your Vet

While North Drugstore cares about the health and safety of your family and pets, we are not, nor do we pretend to be, veterinarians. Your veterinarian is dedicated to looking after the well-being of your cat or dog. Don’t hesitate to ask them for advice regarding flea medication, as your vet will know how best to treat your pet. There are several ways to treat infestations, some of which depend on your pet’s history, weight, and your geographic location. North Drugstore recommends that you consult with your vet prior to ordering Comfortis or its generic equivalent as the dosage depends on your pet’s weight and species. DO NOT give your cat a Comfortis tablet that was meant for a dog, as this can cause some serious adverse effects.

Possible Side Effects

See Comfortis label for complete safety information and talk to your doctor about possible side effects. Comfortis is a safe, chewable beef-flavoured tablet that kills fleas and prevents further infestations for one month. Some adverse effects are possible, but may differ in cats and dogs.

A Note About Comfortis

While Comfortis is a safe and powerful flea medication, it does not protect your pet from other common pests, such as ticks. Ticks are mostly present is humid wooded or grassy areas, but can also be unknowingly carried into the home by pets or humans. Keep your dogs away from tick hot spots until they are treated, as they are at risk of being bitten. Consult your veterinarian before taking your pet into rural areas and learn about tick medication that offers total protection from ticks and tick-related diseases. Be sure to tell your vet that your pet takes monthly Comfortis tablets.
