How to get Comfortis for cat fleas? Is a vet prescription required?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 3 years old | 10 lbs

My cats have fleas that i have not been able to get rid of. Comfortis is the only thing i haven’t tried. I can’t put topical meds on my cats because one of them has dermatitis. is there a way to get comfortis without a prescription? if not, how would i get a prescription from a vet and would it cost money to get the prescription? i have very limited funds, thank you

Comfortis is a prescription product so you will need to see your veterinarian. If you can has been examined within the last year, they may be able to approve the medication for you.
You will also need to call your vet for pricing. It's typically cheaper per dose to buy it in a 6 months supply rather than a single dose. Ask if any rebates are currently running as this could help as well.
To fully get rid of fleas, you will need to treat all the pets for 6 months. I hope this helps.
