Can You Use Frontline on Humans?

Frontline is a product used to control fleas and ticks on dogs and cats. Through an application, the medication keeps fleas and ticks off of your pet for a full month before needing to be reapplied. This kind of protection from being bitten may tempt some people into trying to use Frontline on themselves or other family members. At this point, it becomes an issue of safety for the humans involved.

Use on Humans

Frontline is a pesticide with an active ingredient called fipronil. Fipronil has been studied in rats to monitor possible side effects due to prolonged use of it. According to, fipronil was found to be possibly neurotoxic to dogs as well as the rats involved in the study, conducted by K.A. Jennings and others at Murray State University in Kentucky. The study was published in the Veterinary and Human Toxicology journal in 2002. The rats were exposed to a much higher amount of fipronil than the average Frontline dose, however. In addition to finding that the chemical is potentially neurotoxic, the study also lead to the chemical being classified as a possible human carcinogen. A carcinogen is any substance that can cause cancer. There is also the risk of skin irritation at the site of exposure to fipronil. Vets and groomers received a warning in 1996 in regards to possible contamination from increased exposure to Frontline. For these reasons, the use of Frontline on humans is ill-advised.
