According to the FDA prescribing information Revolution does prevent Heart worm infection. Therefore you can use it instead of Heartgard: Selamectin, the active ingredient in Revolution, is a macrocyclic lactone compound. These compounds effectively prevent the development of adult heartworms when administered to dogs and cats within one month of exposure to infective (L3) Dirofilaria immitis larvae.
