Effitix Spot On Flea Solution for Large Dogs (20-40kg)

Description :

• Effitix is a topical spot-on solution containing fipronil and permethrin, effective against fleas, ticks, lice, and also offers repellent action against mosquitoes and sand flies (which is especially important in areas where Leishmaniasis is a concern) 

• It remains effective after bathing, shampooing, or water immersion and is convenient to apply using its “Drop‑Stop” pipette technology 

Available Dose Size

Effitix comes in multiple weight‑based pipette sizes, and for large dogs (20–40 kg), the correct size is Effitix Spot-On for Large Dogs 

Dosage & Administration Instructions

• The minimum recommended dose is:

  • 6.7 mg fipronil per kg of body weight

  • 60 mg permethrin per kg of body weight 

• A single pipette provides enough for dogs in the 20–40 kg range, delivering approximately 268 mg fipronil and 2400 mg permethrin in total 

• Application:

  • Remove the pipette, tap to settle the contents, break the top, and apply directly to the skin at 2–4 spots along the dog’s spine, from shoulder to tail base 

  • Dogs weighing under 20 kg need 2 application spots; those over 20 kg require 2–4 spots 

• Frequency: Apply monthly, with at least 4 weeks between treatments

Recommendations Before Use

• Use only on dogs 8 weeks or older, and always according to the correct weight-based pipette 

• Avoid use in:

  • Temporary salivation if licked

  • Skin reactions or irritation at the application site

  • Rare neurological signs, vomiting, or respiratory issues—contact your vet if any severe reactions occur 

• Avoid bathing or water immersion within 48 hours after application to maintain efficacy (immersion beyond that may still shorten the 4-week protection)
