Equimax Oral Paste for Horses — a single-dose ivermectin + praziquantel allwormer that kills every major internal parasite in adult horses, including all three species of tapeworm and all three species of bots. Made by Virbac. APVMA-approved in Australia, registered worldwide. Ships USA, Canada and worldwide — no vet prescription required. The complete equine allwormer in a single syringe Equimax is the gold-standard combination horse wormer — one syringe covers every important internal parasite in your horse, including the three that monocomponent wormers regularly miss: tapeworms, bots, and migrating large strongyle larvae. The combination of ivermectin and praziquantel is the most widely-used worming pairing in the world for a reason. One syringe is calibrated to dose a horse up to 700 kg (1,540 lbs) in a single application. Most adult horses fit comfortably inside a single syringe; larger draft breeds or in-foal mares at heavy bodyweight may need a top-up. What Equimax kills Large strongyles (Strongylus vulgaris, S. edentatus, S. equinus) — including arterial-migrating stages Small strongyles / cyathostomins (adult stages) Roundworms (Parascaris equorum) — including ivermectin-resistant strains at label dose Pinworms (Oxyuris equi) Threadworms (Strongyloides westeri) — important in foals Stomach worms (Habronema, Trichostrongylus axei) Lungworms (Dictyocaulus arnfieldi) — especially important in horses pastured with donkeys Bots (Gastrophilus intestinalis, G. nasalis, G. haemorrhoidalis) — all three species Tapeworms (Anoplocephala perfoliata, A. magna, Paranoplocephala mamillana) — all three species Skin micofilariae (Onchocerca species) Active ingredients Each gram of Equimax oral paste contains 18.7 mg ivermectin and 140.3 mg praziquantel. One syringe contains 7.49 g of paste — enough for one 700 kg (1,540 lb) horse. How to give Equimax Estimate your horse's weight using a weight tape or scale Set the dose ring on the syringe to the corresponding weight mark Make sure your horse's mouth is empty of feed Place the syringe nozzle at the back of the tongue, on either side Depress the plunger and immediately raise your horse's head to ensure the paste is swallowed Do not divide one syringe between two horses unless both are dosed at the same time When to use Equimax Equimax is the right wormer when you need full-spectrum cover including tapeworm and bots — typically at the autumn worming (after bot fly season), the spring worming (after tapeworm transmission peaks), and any time your horse is being introduced to a new herd or boarding facility. For rotation, alternate Equimax with a benzimidazole-class wormer like Strategy-T to slow resistance build-up. Why owners choose Equimax Single-dose convenience — one syringe, all major worms, no need to combine multiple products The textbook tapeworm + bot wormer — most monocomponent wormers miss both Safe in foals from 2 weeks of age, in pregnant mares and in breeding stallions From Virbac, the most widely-distributed equine pharmaceutical company in the world Compatible with rotation programs — pairs cleanly with Strategy-T and Ultimum to build a 3-class rotation Other options in this range Equimax Elevation — same actives in an apple-flavoured paste, designed for fussy eaters and foals Equimax LV — same actives in a low-volume (smaller) syringe, easier to administer to tricky horses Strategy-T — different drug class (oxfendazole + pyrantel) for rotation Ultimum — long-acting moxidectin + praziquantel, catches encysted small strongyles Equimec — an ivermectin-only paste, cheaper per dose but doesn't cover tapeworm Browse the full horse wormer range for boticides, calming pastes and supplements Worldwide shipping — no prescription required We ship Equimax to the USA, Canada, UK, Europe and worldwide. No vet prescription needed. International tracking included on every order. Frequently Asked Questions Q: How often should I worm my horse? A: 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. Q: How do I dose by weight? A: 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. Q: Can I worm my pregnant mare? A: 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. Q: Why should I rotate between wormers? A: 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. Q: Are these wormers safe for foals? A: 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. Q: Do I need a prescription? A: No. All Virbac horse wormers in this range are sold over the counter — no vet prescription required. We ship to the USA, Canada, UK, Europe and worldwide.
