Frontline is a topical flea and tick medication that is applied to the skin between the shoulder blades. It works by killing fleas and ticks that come into contact with the treated area. The active ingredient in Frontline, fipronil, is a synthetic pyrethroid that is toxic to insects.
While Frontline is generally safe when used as directed, giving it to your dog more often than once a month can increase the risk of side effects. These side effects can include:
* Skin irritation, including redness, itching, and swelling
* Respiratory problems, such as coughing, sneezing, and difficulty breathing
* Neurological issues, such as seizures, tremors, and dizziness
* In some cases, Frontline can even be fatal
If you are concerned about fleas and ticks on your dog, talk to your veterinarian about the best way to prevent and treat them. There are a variety of safe and effective flea and tick medications available, and your veterinarian can help you choose the one that is right for your dog.
