Frontline to Dogs and Humans, Fipronil may cause slight skin irritation and mild eye irritation in humans. The clinical signs and symptoms reported after the ingestion of fipronil by humans include sweating, nausea, vomiting, headache, abdominal pain, dizziness, agitations, weakness, and seizures (Fung et al.
Frontline, a common flea preventative that disrupts flea neural receptors, is a suspected carcinogen and endocrine disruptor that can be toxic to the nervous system if ingested. It can also cause less serious side effects in dogs, such as irritation at the spot of application, diarrhea, vomiting, and seizures. Because we interact so closely with our dogs, Frontline can cause similar problems in us.
Front line components
The main chemical in Frontline is fipronil, the chemical that disrupts insect nerve receptors. Fipronil is a known carcinogen that increases its potency in sunlight – although it is not as effective as blocking mammalian nerve receptors, it can be harmful to both dogs and humans, especially if it is ingested. Frontline also includes S-Methoprene, an insect growth regulator. The insect’s outer structure prevents growth and stops insect growth. This chemical is not believed to be harmful to humans.
Side effects of dogs
Place the front line locally between the shoulder blades – never allow the dog to eat it. Use the Elizabethan collar if necessary. If you keep the fluid trapped in the area behind the neck and between the shoulder blades, the dog should not be able to reach it – but another pet can lick it. If taken, consult a veterinarian immediately.
Topical application, Frontline sometimes causes irritation around the application spot. Some dogs experienced rashes, diarrhea, vomiting, and seizures, but these side effects were usually due to ingestion.
Human side effects
Fipronil is suspected to be a carcinogen and deformed to the endocrine glands. It can also be toxic to the nervous system, especially if it is ingested. Signs of a negative reaction include headache, dizziness, and seizures. Less serious reactions from nausea, vomiting, and weakness may be signs of the body’s response to toxicity. Children are especially vulnerable because they are more likely to pet a dog and place their hands in their mouths or play with toys in dogs and dog areas.
While Frontline has been a successful treatment for flea infections without problems in many dogs, if you are concerned about putting chemicals on your dog, alternative treatments are available. Some essential oils, such as lavender and eucalyptus, succeed in fending off fleas. You can also prevent showering and frequent cleaning. Clean the dog areas frequently, and empty the vacuum outside to remove eggs that can stay dormant for months.
