The HEARTGARD Chewable should be given so that dogs chew and swallow. Care should be taken to ensure that the dog chews and does not swallow whole. For dogs that normally swallow whole, the chewables can be broken into pieces. HEARTGARD Chewables should be given at monthly intervals during the period of the year when mosquitoes (vectors), potentially carrying infective heartworm larvae, are active. The initial dose must be given within a month (30 days) after the dog’s first exposure to mosquitoes. The final dose must be given within a month (30 days) after the dog’s last exposure to mosquitoes.

When replacing another heartworm preventive product in a heartworm disease prevention program, the first dose of HEARTGARD must be given within a month (30 days) of the last dose of the former medication. If the interval between doses exceeds a month (30 days), the efficacy of ivermectin can be reduced. Therefore, for optimal performance, the chewable must be given once a month on or about the same day of the month. If treatment is delayed, whether by a few days or many, immediate treatment with HEARTGARD and resumption of the recommended dosing regimen will minimize the opportunity for the development of adult heartworms.

All dogs should be tested for existing heartworm infection before starting treatment with HEARTGARD which is not effective against adult D. immitis. Infected dogs must be treated to remove adult heartworms and microfilariae before initiating a program with HEARTGARD. While some microfilariae may be killed by the ivermectin in HEARTGARD at the recommended dose level, HEARTGARD is not effective for microfilariae clearance. A mild hypersensitivity-type reaction, presumably due to dead or dying microfilariae and particularly involving a transient diarrhea, has been observed in clinical trials with ivermectin alone after treatment of some dogs that have circulating microfilariae.

IMPORTANT NOTE: If swallowed call a poison control center or doctor immediately for treatment advice. For hazards to domestic animals the 24-hour assistance line within the U.S.A. is 1-800-660-1842.
