Prescribing Information for Veterinary Professionals

Advantage® II is an easy-to-apply topical that kills fleas through contact, so that they don't have to bite your pet to die. Advantage® II kills fleas rapidly — within 12 hours of initial application — and is waterproof after 24 hours.

Advantage® II effectively treats existing flea infestations and prevents further infestations by killing flea eggs and larvae to break the flea life cycle. Reinfesting fleas are killed within 2 hours, and protection against further flea infestation lasts for up to a month. For use on cats and kittens 8 weeks of age and older, weighing 2 lbs. or more.
