Interceptor must be administered monthly, preferably on the same date each month. It is recommended (and most manufacturer guarantees require) that Interceptor be given year round, although some veterinarians may recommend giving it only during the mosquito season. If given seasonally, the first dose must be given within 30 days of the pet's first exposure to mosquitoes. The last dose must be given within 30 days after the pet's last exposure to mosquitoes
Most dogs and cats like the taste of Interceptor and will accept the tablet as a treat. Interceptor may be crumbled and mixed with some food. Care should be taken that the dog consumes the complete dose, and treated animals should be observed for a few minutes after administration to ensure that part of the dose is not lost or rejected. If not entirely consumed, give another full recommended dose as soon as possible.
