LongRange is the first extended-release injection that delivers 100 to 150 days of parasite control in a single dose, thanks to its unique Theraphase technology. The unique Theraphase formulation allows LongRange to go to work immediately and continue to work for an extended period of time. A single spring treatment works long enough to break the parasite life cycle and reduce pasture reinfestation.
