Comfortis tablets are given once a month to control fleas on dogs and cats. The drug is lethal to blood sucking insects but has little or no effect on dogs. (Occasionally dogs will vomit after taking a tablet.) It is best to give Comfortis with food. This reduces the chances of vomiting as well as enabling a more persistent flea-killing effect afterwards, so that one tablet will last for the whole month. Comfrotis tablets come in five different sizes to suit dogs of different body weights and two sizes for cats. Comfortis is not recommended for dogs under 14 weeks of age, or less than 3.9kg bodyweight.

See below the list of products for the Dosage information for dogs and cats.

15 Gave my dog seizures

By on 29 April 2018

Scruffy was on this medication for a few years. He stated getting seizures but couldn’t figure out what was triggering it. I sent all his details to the canine epilepsy group and they told me to not give him this product. It’s now been nearly a year without seizures and without comfortis

Verified Purchase

By on 23 April 2017

I have used Comfortis for Pedro for a few years now, as he is allergic to spot on and collars. It works well and I haven't seen a flea since he has been on it. The only downside is that the tablets are quite big, but I break them into 4 and hide them in cheese spread

most efficient product to date that we have used for all our cats and dogs in keeping fleas and ticks under control. Not only on the dog but in the floorboards inside and in the gravel of the yard

My dog was sick


My dog was sick 4 hours after takeing comfortis.will it still work.

  • VioVet Staff

The active ingredient should have been absorbed in less time than 4 hours so I it likely to be fully effective. Not possible to guarantee, but should be OK. (It is always best to give this tablet with food to help reduce the chances of vomiting and to increase the effect. )

Comfortis quantity


I have a prescription for 9 tablets but the packs come in 6, can I order 9 tablets.

  • VioVet Staff

Sorry but we do not split packs, so have to sell them in multiples of 6. If we send just 6 now, then the remaining 3 would remain on your "allowed list" until you need them, but you would need another prescription to go with it.
