About this medicine
Selamectin prevents heartworm and treats fleas, ear mites and some worms (spot-on).
Products with this ingredient include Revolution. The FDA hides brand names in its public data, so these reports cover every product with the same active ingredients.
Some herding breeds (for example Collies) carry the MDR1 gene variant and can be more sensitive to this drug class at high doses.
