Credelio (Lotilaner)

Pet Size

Don't know your pet's weight?

If you can't get them on the scale, try this super simple method:

  1. Weigh yourself.
  2. Weigh yourself holding your pet.
  3. Subtract the two numbers to get their weight.

Too heavy to hold? Your vet will weigh them if you ask (or may already have it on file if you call).


No Prescription Required

  • Description

    Credelio is a prescription flea and tick medication for dogs administered as a chewable tablet that dogs take once a month to kill fleas and ticks. The active ingredient, Lotaliner, is absorbed into your pet's bloodstream and then ingested by the parasites when they bite the animal. It begins killing fleas and ticks within 4 hours and kills 99% of fleas and 97% of ticks within 8 hours. This oral flea and tick tablet is flavored so that dogs will happily eat it as a treat and all that is required of the pet owners is to give it to them at the same time each month.

    You can buy Credelio with a prescription, and your best price on it will be when you order from World Pet Express.


    Give your pet one Credelio flea and tick chewable once a month, and at the same time each month. Credelio should be administered with food or within 30 minutes of feeding so that the dog has peak blood levels and exposure.


    The active ingredient in Credelio is Lotaliner.


    Dogs with a history of seizures or neurologic disorders may not be suitable for using Credelio for dogs, and this is something that you should discuss with your veterinarian before getting a prescription or starting on this flea and tick killer medication for dogs.

    Use with caution and only with veterinarian's approval if your dog is breeding, pregnant or lactating.


    There are no established drug interaction risks between Credelio and other Pet Rx or OTC medications, but it is best to tell your veterinarian of all medications your pet is currently taking before getting the prescription and proceeding to buy Credelio.

    Side Effects

    Side effects from Credelio flea and tick are uncommon, but some dogs may experience weight loss, elevated blood urea nitrogen, increased urination, or diarrhea. If your dog experiences these side effects, you may want to discontinue use and speak to your veterinarian again regarding flea and tick control for dogs.
