Advocate covers everything that Revolution covers. However, neither of them cover ticks.

This is very powerful medicine made by Bayer. It is their most popular brand as it really works. We would definitely recommend it. However, Advantage Multi (Advocate) covers Flea and intestinal parasites (almost all of them) including heartworm but no ticks. Frontline and Advantix cover flea and ticks but no intestinal worms. If you wish flea+ticks medicine we can also recommend Nexgard which produced by Merial (makers of Frontline). It is relatively new but we have great feedback from our customers.

Advantage Multi doesn't contain ivermectin. Its active substances are: imidacloprid and moxidectin. So it should be saf but please get advise from your Vet before apply any medicine to your pets. It does treat lice.
