Comfortis®(1620mg) 6 Chewable Tablets for Extra Large Sized Dogs 60.1-120lbs (27.1-54kg) EXP 11/2020
Comfortis® (spinosad) is a fast, safe and effective treatment for flea infestations on your dog or cat. It starts killing fleas faster than Nexgard® (afoxolaner)*,2, and in a controlled laboratory study in dogs, Comfortis killed 100% of the fleas in just four hours.
The worst part of a flea infestation is not what you can see–it's what you can't. Microscopic flea eggs, larvae and pupae can permeate your home and keep the flea infestation cycle going. Comfortis kills fleas before they lay eggs, and Comfortis keeps killing fleas for a full month with each dose. Use Comfortis for at least three months to treat a current flea infestation, then continue routine use to prevent a reinfestation on your pet. In a field study conducted in households with existing flea infestations in dogs, flea count reductions of 97.9% were observed one month after the first treatment and 99.9% after three monthly treatments with Comfortis.
With more than 80 million doses dispensed3, you can trust Comfortis when you want fleas dead and gone.

How it Works:
Spinosad kills fleas by causing excitation of the insect's nervous system, leading to paralysis and rapid death.
Side effects may occur, including vomiting. If your pet is experiencing loss of appetite, lethargy, or any other difference in behavior, contact your veterinarian. The FDA has received reports of adverse reactions in dogs receiving the drug Comfortis (spinosad) concurrently with high, extra-label doses of ivermectin. Dogs receiving extra-label doses of ivermectin to treat non-responsive demodectic mange and other conditions have developed signs of ivermectin toxicity. Ivermectin is an ingredient found in heartworm preventatives such as Heartgard Plus, Heartgard, Iverhart Plus and Ivomec. In cats, the most common adverse reaction recorded in clinical trials was vomiting. Other adverse reactions were: lethargy, decreased appetite, weight loss, and diarrhea. Use with caution with concomitant extra-label use of ivermectin.
