---

Product Overview

The ultimate defense against the most dangerous hidden threat to your horse’s health. The Panacur® PowerPac is a complete, 5-day deworming program designed to safely and effectively eliminate all major internal parasites, including the encysted larval stages of small strongyles. While standard dewormers only kill adult worms, the PowerPac protocol provides a comprehensive purge that targets parasites at every stage of their lifecycle.

Manufactured by Merck Animal Health, this FDA-approved kit contains five 57g syringes of Panacur® (fenbendazole) Paste 10%. It is the veterinarian’s #1 choice for treating horses with chronic weight loss, poor performance, or for providing a “clean slate” deworming for new arrivals or horses with an unknown history. Don’t just manage parasites—eliminate them with the proven power of the Panacur® PowerPac.

What is the Panacur® PowerPac?

The PowerPac is a specific 5-day treatment regimen that uses a double dose of fenbendazole each day. This sustained, elevated dose is the key to killing the dangerous encysted small strongyle larvae that burrow into the intestinal wall. These hidden parasites are protected from single-dose dewormers and can cause severe colic, diarrhea, and permanent gut damage when they emerge en masse. The PowerPac is the gold-standard method for safely eliminating this threat.

Key Features & Benefits

• Targets Encysted Small Strongyles: The primary reason for a PowerPac. The 5-day protocol effectively kills the encysted (hypobiotic) L3/L4 stages of small strongyles that other single-dose dewormers miss.
• Complete 5-Day System: This all-in-one box contains all five syringes needed to complete the full larvicidal treatment for a horse up to 1,250 lbs. No guesswork, no need to buy multiple products.
• Convenient 57g Syringe Size: Each syringe is specifically sized to deliver the full daily “double dose” to a 1,250 lb horse, eliminating the need to administer two smaller syringes each day.
• Broad-Spectrum Efficacy: In addition to encysted larvae, the protocol is highly effective against large strongyles, adult small strongyles, pinworms, and ascarids.
• Exceptional Safety Profile: Panacur® (fenbendazole) is known for its wide margin of safety and is approved for use in horses of all ages, including pregnant mares and stallions.
• The Trusted Merck Brand: Rely on the unparalleled research, quality, and efficacy of a product from the global leader in animal health.
