Inasmuch as my wife just asked me about using 'Comfortis' for flea control on our Golden, I did a search and an FDA warning showed up.

COMFORTIS® and ivermectin interaction Safety Warning Notification

http://www.fda.gov/animalveterinary/.../ucm047942.htm

My question is since we DO use Ivermectin in the 4:1 ratio with Glycol:Ivermec, should I ASSUME that that is NOT(?) the dosage that's being referred to in this FDA warning?

OR is the mixing of Ivermectin and COMFORTIS a bad idea no matter what?


We've always used 'Program' on a monthly basis for flea control, but Program is no longer being produced, so we're looking for the best alternative.

Any info from the gallery here on this issue???
