Advantage Multi is a monthly topical solution to prevent heartworm disease, kill adult fleas, treat and control hookworms, roundworms, whipworms, and sarcoptic mange.
Your pet needs to be on heartworm prevention every 30 days to prevent heartworm disease. Whether the preventive you choose is given as a pill or a spot-on topical medication, all approved heartworm medications work by eliminating the immature (larval) stages of the heartworm parasite. This includes the infective heartworm larvae deposited by the mosquito as well as the following larval stage that develops inside the animal. Unfortunately, in as little as 51 days, immature heartworm larvae can molt into an adult stage, which cannot be effectively eliminated by preventives. Because heartworms must be eliminated before they reach this adult stage, it is extremely important that heartworm preventives be administered strictly on schedule (monthly for oral and topical products). Administering prevention late can allow immature larvae to molt into the adult stage, which is poorly prevented.
