PERMETHRIN spot-on

Important safety and use flags

• DOGS ONLY — fatal cat boundary. Never apply to a cat. Keep every treated dog completely separated from cats for 72 hours and prevent cats from grooming the dog, sharing bedding/brushes or contacting the wet site. Any feline exposure needs immediate veterinary decontamination and toxicology care.
• Exact dose: 2-15 kg, 1 ml on intact skin between the scapulae; from 15 kg to 30 kg and above, 1 ml there plus 1 ml at the tail base. The source bands overlap at exactly 15 kg: verify weight and physical leaflet and document one selected band.
• Do not use below 3 months or 2 kg, during pregnancy/lactation, on damaged skin, in a sick/convalescent dog or with hypersensitivity. Do not repeat sooner than 14 days and do not transfer a dose from another permethrin product.
• The label covers Ctenocephalides felis for four weeks and Ixodes ricinus/Rhipicephalus sanguineus for more than four weeks. No controlled exact-product outcome was found and mg/kg exposure falls sharply across broad weight bands; inspect response and do not promise uniform month-long control, especially in large dogs.
• Apply directly to visible intact skin, not hair, and prevent licking. Frequent swimming or bathing may reduce efficacy. Treat all dogs in the household when indicated and use a cat-appropriate product for cats; integrate environmental flea control rather than relying on one spot-on alone.
• Mild irritation may last up to 48 hours; temporary hypersensitivity/scratching and rare alopecia, CNS intoxication or GI disturbance are labelled. Hyperesthesia, tremor, hypersalivation, diarrhoea, temperature change or convulsion needs immediate washing with non-insecticidal shampoo and urgent veterinary care; no antidote exists.
• Keep away from flame until fully dry, do not touch the application site for 3-6 hours, preferably treat in the evening and do not let the dog sleep with people—especially children. Wear gloves, wash hands and rinse eyes for 15 minutes after accidental exposure.
• The exact label says no known interactions, not proven universal compatibility. Review all other ectoparasiticides and pesticides; do not layer treatments or shorten the interval without an explicit evidence-based plan, particularly after adverse signs or poor response.
• Permethrin is toxic to fish, aquatic organisms and bees. Prevent entry into water, drains and hives; keep the dog away from water while wet, dispose locally as hazardous veterinary/pesticide waste and never reuse the container.
• Store below 25 C in the original dry container away from heat, direct sunlight, food and drink. Mark first opening and discard after two months; verify the exact 10 ml glass dropper bottle, authorisation, lot and expiry before each measured dose.
