Ivermection should never be used along with Comfortis!

COMFORTIS® and ivermectin interaction Safety Warning Notification

That's also good to know. Comfortis is the "flea pill" right? I have my baby on Frontline spray that you spray on them every 3 months. I also use the Minksheen shampoo as another step to prevent flea and mosquito bites. Although the shampoo doesn't do all that much to prevent flea and mosquito bites. But I am very happy with what it does to her coat.
