DO YOU KNOW WHAT SIGNS OF HARMFUL REACTIONS😿🚑 TO WATCH FOR WHEN USING FLEA & TICK CHEMICALS ON YOUR PET?💊💦
As warmer weather approaches,☀️ it’s time to start thinking about protecting your pet from fleas, ticks, and even heartworm.🦟 When pet owners reach for those flea and tick treatments—whether chewables, spot-ons, or other parasiticide products—many don’t realize that adverse reactions can occur.
That’s why it’s crucial to know the signs and symptoms to look for so you can report any concerns to your veterinarian promptly.
The challenge is that different flea and tick treatments use various chemicals, each with its own potential side effects. For example, isoxazoline, a common insecticide, is highly lipophilic and easily absorbed by the body. It’s been known to cause a range of reactions, including seizures, behavior changes, gastrointestinal issues, and more.
These type of reactions can even happen in humans if ingested as a 2-year-old boy (12 kg), the son of a veterinarian, ingested two chewable tablets💊 and developed an unsteady gait🫨 approximately 50 minutes later. By 2 hours after ingestion, he had ataxia, tremor, confusion and hallucinations. He was sedated with midazolam, and 10 hours after ingestion was only minimally ataxic.
According to a recent study published in Vet Record, “The true incidence of neurological adverse effects from isoxazolines remains unclear. The delay between the administration and onset of signs can be long, and the association may be missed. A lack of timing information in the summary of product characteristics could also contribute to missed attribution of adverse effects.”
