Ask your veterinarian

Your veterinarian is your best source of advice about your dog's healthcare. That's why Comfortis (spinosad) is available through your veterinarian.

Your veterinarian can ensure the proper dosage of Comfortis and recommend other products that can help protect your dog's health. Consulting your veterinarian can help you avoid the costly — and potentially dangerous — trials-and-errors that pet owners could experience with over-the-counter products.

Your veterinarian can also make recommendations about flea treatment times and duration for your geographic area and specific household. For instance, to minimize the likelihood of flea reinfestation, it's advisable to treat all animals in your household with an approved flea product. Ask your veterinarian about Elanco flea-control products for your other pets.

Green Chemistry

The introduction of spinosad for use in agriculture resulted in the receipt of a Presidential Green Chemistry Challenge Award² in 1999 from the U.S. Environmental Protection Agency. The award was presented to Dow AgroSciences LLC in the category of “Designing Safer Chemicals” for the introduction of spinosad as an insect control product for use on crops. This award demonstrates that spinosad as a technology for insect control has a favorable environmental profile. This award is not relevant to the safety and efficacy of Comfortis, nor does it confer any environmental benefit to Comfortis.

Comfortis is not for use in humans. Like all medications, keep Comfortis out of reach of children.
