Equimax Paste: Common Questions About Horse Deworming

Quick answer

Equimax paste is a horse wormer paste dosed by body weight, and most owners use it on a schedule set with their veterinarian rather than on a fixed calendar. Weigh your horse, dial the correct dose, and rotate active ingredients across the year so parasites don't get comfortable with one formula. If you are unsure about timing or dose, ask your vet before you treat.

Equimax paste raises a handful of practical questions every horse owner eventually asks: how much, how often, and what happens if the dose doesn't go in cleanly. This FAQ answers those directly so you can build a deworming routine that actually fits your barn.

These answers cover the everyday decisions around horse parasite control. They are general guidance, not a substitute for your veterinarian's advice for your specific horse, region, and pasture situation.

How is Equimax paste dosed for horses?

Equimax is a horse wormer paste dosed by body weight, so the tube's weight markings are the starting point, not a guess. Weigh your horse with a scale or a weight tape, then set the dial to the matching mark and deposit the paste on the back of the tongue. A horse that has gained or lost condition since the last deworming may need a different mark than you remember.

If your horse sits between two weight marks, ask your veterinarian which way to go. Under-dosing is a common reason deworming underperforms, and over-dosing wastes product and money.

• Weigh before every treatment, not just once a year.
• Deposit paste on the back of the tongue to encourage swallowing.
• Keep the tube at room temperature so the paste flows evenly.

How often should I deworm my horse?

There is no single schedule that fits every horse. Many veterinarians now recommend a targeted approach based on fecal egg counts rather than deworming every horse on the same calendar. Your vet can tell you whether your horse is a low, moderate, or high shedder and how often it needs treatment.

Factors that change the answer include age, pasture stocking density, whether horses are turned out together, and your climate. A young horse or one on a crowded pasture usually needs more attention than a solitary adult on dry lot.

• Ask your vet about fecal egg counts before setting a schedule.
• Track treatment dates so you can see the pattern over a year.
• Recheck after any change in pasture or herd mates.

Should I rotate dewormers, and where does Equimax fit?

Rotation means changing the active ingredient class across the year, not just switching brand names. Equimax combines praziquantel and ivermectin, so it covers tapeworms as well as several other common parasites. Many owners use a product like this once or twice a year and use a different class for the other treatments.

Your veterinarian is the right person to design the rotation because parasite pressure varies by region. Randomly alternating products without a plan can waste doses and speed up resistance.

• Rotate active ingredients, not just labels.
• Keep a simple log of product name and date for each treatment.
• Never repeat the same class back-to-back without veterinary guidance.

What if my horse spits out the paste or I miss a dose?

If most of the paste ends up on the stall wall, you cannot assume the dose was delivered. Contact your veterinarian about whether to repeat the treatment or wait until the next scheduled date. Repeating too soon is not automatically harmless, so get advice rather than guessing.

For a missed scheduled dose, treat as soon as you remember and then adjust your calendar from that new date. Do not double up to make up for lost time.

• Check the horse's mouth after dosing to confirm the paste went down.
• Note the actual treatment date in your log, not the planned one.
• Call your vet before repeating a dose.

Can I use Equimax paste on foals, pregnant mares, or donkeys?

Those groups need a veterinarian's decision, not a general rule. Foals, pregnant or nursing mares, and donkeys can respond differently to deworming products, and the right choice depends on age, stage of pregnancy, and the specific parasite risk. Ask your vet before treating any of them.

The same caution applies to horses with underlying health conditions or those already on other medications. Your vet can check for interactions and confirm the timing.

• Do not assume an adult horse dose fits a foal.
• Confirm suitability for pregnant mares with your vet.
• Mention every other medication your horse receives.

How should I store Equimax paste?

Keep the tube closed and store it at room temperature, away from direct sun and freezing temperatures. Extreme heat can change the paste's consistency, and a frozen tube may not dose accurately even after it thaws.

Check the expiration date before each use and discard expired tubes. If the paste looks separated or unusually stiff, do not use it.

• Store upright with the cap tight.
• Avoid the tack room windowsill and the truck glovebox.
• Write the purchase date on the box so you can track shelf life.

Equimax paste FAQ at a glance

Dose by weight

Weigh your horse before each treatment and set the tube dial to the matching mark. Between two marks, ask your vet which way to go. Under-dosing is a common reason deworming underperforms.

Schedule with your vet

Targeted deworming based on fecal egg counts fits most horses better than a one-size-fits-all calendar. Recheck after any change in pasture or herd mates.

Rotate active ingredients

Equimax combines praziquantel and ivermectin. Rotate by drug class across the year rather than switching labels randomly. Keep a dated log of every product you use.

Confirm the dose went in

If your horse spits out the paste, do not assume the treatment worked. Call your vet before repeating it. Note the actual treatment date, not the planned one.

Special groups need a vet

Foals, pregnant or nursing mares, donkeys, and horses on other medications need individualized advice. Mention every other medication your horse receives.

Products that support a deworming and aftercare routine

• MalAcetic Ultra Otic Cleanser for Dogs, Cats & Horses: MalAcetic Ultra Otic Cleanser is an ear cleanser used as a drying agent in dogs, cats and horses with inflamed and infected ears due to bacterial and fungal (yeast) infections. Horses on pasture often deal with dirty, damp ears alongside parasite pressure, so a cleanser labeled for horses can be part of routine care. It is not a dewormer and does not replace parasite treatment.
• Gauze Sponge 12-Ply, Woven, Non-Sterile: These gauze sponges are made from 100% premium bleached cotton and are applicable for dressing, general cleaning, prepping, packing and debriding wounds. Barn life produces small cuts and scrapes, and having absorbent gauze on hand makes basic wound cleaning easier while you wait for veterinary advice.
• Adequan i.m. (Polysulfated Glycosaminoglycan) Injection for Horses 100mg/mL, 50 mL (Multi-Dose): Adequan i.m. Multi-Dose is a prescription injectable for horses with non-infectious degenerative and/or traumatic joint dysfunction and the lameness that comes with it in the carpal and hock joints. Joint comfort and parasite control are separate concerns, but both affect how well a horse moves and works. This is a prescription product, so it requires veterinary direction.

Equimax paste works best as part of a plan you build with your veterinarian, not as a standalone purchase. Weigh your horse, log every treatment, and rotate ingredients thoughtfully so your horse parasite control stays effective season after season.
