Moxidectin (the active in Ultimum) is one of the only wormers that kills them. If your horse has had heavy strongyle burdens, lives on a high-traffic property or has just been added to a new herd, Ultimum is the wormer to reach for.\u003c\/p\u003e\n\n\u003ch3\u003eWhat Ultimum kills\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEncysted small strongyles\u003c\/strong\u003e (cyathostomin L3 and L4 larvae) — the key difference vs ivermectin-based wormers\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eAdult small strongyles\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge strongyles\u003c\/strong\u003e (all three species, including migrating larvae)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoundworms\u003c\/strong\u003e (Parascaris equorum)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePinworms\u003c\/strong\u003e (Oxyuris equi)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreadworms\u003c\/strong\u003e (Strongyloides westeri)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStomach worms\u003c\/strong\u003e (Habronema, Trichostrongylus axei)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLungworms\u003c\/strong\u003e (Dictyocaulus arnfieldi)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBots\u003c\/strong\u003e (Gastrophilus species — all three)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapeworms\u003c\/strong\u003e (Anoplocephala perfoliata, A. magna, Paranoplocephala mamillana) — all three species\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eActive ingredients\u003c\/h3\u003e\n\u003cp\u003eUltimum contains \u003cstrong\u003emoxidectin\u003c\/strong\u003e and \u003cstrong\u003epraziquantel\u003c\/strong\u003e in a gel paste formulation.

Equimax uses ivermectin + praziquantel; Ultimum uses moxidectin + praziquantel. Moxidectin is longer-acting and catches encysted small-strongyle larvae that ivermectin misses, which is why Ultimum is the more comprehensive (and more expensive) option.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why is Ultimum more expensive than Equimax?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Moxidectin (the macrocyclic lactone in Ultimum) is more expensive to manufacture than ivermectin, and it kills more parasite life-stages — including the encysted small-strongyle larvae that cause the most damage in adult horses. Used once or twice a year as part of a rotation, Ultimum delivers the broadest single-dose cover available in equine worming.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use Ultimum every worming?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Vets generally don't recommend using moxidectin every worming, because it accelerates resistance build-up in the same way over-using ivermectin does. Use Ultimum once or twice a year, alternating with Equimax (ivermectin) and Strategy-T (oxfendazole + pyrantel) for the other rotations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How often should I worm my horse?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Most vets recommend worming adult horses every 8–12 weeks, rotating between drug classes (e.g. Equimax → Strategy-T → Ultimum) to slow the build-up of parasite resistance. Foals are wormed more often (every 4–6 weeks) and pregnant mares should be dosed 4–6 weeks before foaling. Faecal egg counts every 6 months are the most accurate way to fine-tune your worming schedule.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I dose by weight?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Estimate your horse's weight using a weight tape, a livestock scale, or the bodyweight formula (girth² × length ÷ 11,990). Set the plunger of the syringe to the corresponding weight mark, place the syringe at the back of the tongue and depress. Hold the horse's head up for a few seconds to make sure the paste is swallowed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I worm my pregnant mare?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Yes — all the products in this range are safe in pregnant mares when used at label dose. The standard recommendation is to worm 4–6 weeks before foaling, especially with a praziquantel-containing product (Equimax, Equimax Elevation, Equimax LV or Ultimum) to clear tapeworm before delivery.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why should I rotate between wormers?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Equine worms — especially small strongyles (cyathostomins) — develop resistance to single-class wormers when they're used continuously. Rotating between three or more drug classes makes resistance much slower to develop. The textbook rotation is: a macrocyclic lactone (Equimax\/Equimax Elevation\/Equimax LV\/Ultimum) → a benzimidazole + tetrahydropyrimidine (Strategy-T) → back to a macrocyclic lactone. Faecal egg count testing helps you confirm your rotation is still effective.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Are these wormers safe for foals?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Equimax Elevation is specifically formulated for foals from 2 weeks of age. Equimax and Equimax LV are safe in foals from 2 weeks of age at the correct dose. Strategy-T and Ultimum are for horses over 4 weeks of age. Always check the label dose for very young foals.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do I need a prescription?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: No. All Virbac horse wormers in this range are sold over the counter — no vet prescription required.
