The Powerpac exists for one job ordinary rotation cannot do: five consecutive days at a doubled fenbendazole dose, reaching the encysted small strongyle larvae walled into the gut lining where single-day wormers never touch them. A vet-directed course — run it on their calendar.
- 57 g of 10% fenbendazole paste sized for the labeled five-day protocol
- Double-dose regimen targets encysted early and late third and fourth stage cyathostome larvae
- The standing answer to late-winter larval cyathostominosis risk in young and rescue horses
- Order complete before day one — the protocol does not pause for deliveries
- Distributed through Merck/Durvet channels; confirm count and size on the listing
Five days at double strength
The Powerpac protocol runs 10 mg of fenbendazole per kilogram — twice the rotation dose — every day for five consecutive days. That sustained saturation is what reaches through the gut wall to larvae in their cysts; it is the same patience-beats-force philosophy as the dog shelf's three mornings, stretched to the harder target.
Because the course cannot pause, the cardinal rule is logistical: every day's paste in the barn before day one. A protocol interrupted at day three by a late truck is a protocol restarted.
The larvae ordinary mornings miss
Encysted small strongyles spend the grazing season bricking themselves into the intestinal lining, immune to single-day wormers, then emerge en masse in late winter — the syndrome called larval cyathostominosis, and a genuine colic risk in young, heavily grazed and rescue horses. This is the case the Powerpac was labeled for.
It is also precisely why the course is vet-directed: whether a horse needs it at all is a fecal-count and history judgment, and resistance stewardship means the double dose is aimed, never routine. Bring the question to the clinic before bringing the box to the barn.
