Equimax Allwormer Oral Paste for Horses

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

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.
