Hello from Britain I went to my vet's today and we got talking about Ivermectin and other medication against parasites, and he mentioned that Frontline had brought out a new treatment, a solution for SPOT ON application. It comes in pipettes of 0.5 ml which contain 50 mg fipronil, and you apply the contents at 2 points, one at the base of the skull and a second 2-3 cm further back. The Frontline SPOT ON spreads rapidly from the site of treatment to cover the whole surface of the animal within 24 hours and lasts up to 5 weeks. After application, absorption of fipronil through the skin is negligible. Is this safe for ferrets? What would be the dose for them? For cats it says approximately 7.5-15 mg/kg. How does it spread to cover the whole surface of an animal? How does that work? What is the difference to Frontline spray? I was also wondering about different forms of Ivermectin. I know it's usually injected but could you get it as a spot on application that is absorbed into the body? I just thought it might be better for frail, thin, old, poorly, small etc. ferrets or animals in general. No needle and no pain. I hope someone (vets?) can answer my questions... Thanks! Love to all fuzzies out there. Ulrike [Posted in FML issue 1876]
