What Strongid P® Is and How It Works

Strongid P® contains pyrantel pamoate, a broad-spectrum anthelmintic for equine use. Pyrantel is a depolarizing neuromuscular blocker that paralyzes susceptible parasites so they are expelled in manure. The paste targets large strongyles, small strongyles, pinworms, and roundworms. At a double dose, it is used for tapeworm control in horses. This makes Strongid P for horses a practical choice for routine strategic deworming and seasonal tapeworm treatment.

At CanadianInsulin, orders are filled by licensed Canadian pharmacies after we confirm a valid prescription with your clinic.

Each calibrated syringe delivers a palatable pyrantel pamoate horse paste. It is designed for oral dosing and allows weight-based adjustments. Many owners refer to it as a Strongid P horse wormer or Strongid P horse dewormer paste. If you are comparing options, note that Strongid P paste 43% is widely recognized and easy to dose. For tapeworms specifically, some programs use a Strongid P double dose as directed by a veterinarian.

Who Strongid P® Is For

This product is labeled for horses and ponies. It is commonly used across life stages when used as directed. Discuss use with a veterinarian for very young foals, debilitated animals, or horses with known sensitivities. Do not use in species other than equines unless a veterinarian advises otherwise.

Tapeworm control is an important part of parasite management. For context on tapeworm treatment in small animals, see our editorial on Droncit For Cats. Equine recommendations differ; always follow horse-specific guidance.

Dosage and Usage

Use the syringe’s weight markings to set the intended dose. The standard label dose is 3 mg pyrantel base per pound of body weight for strongyles, pinworms, and roundworms. For tapeworms, a single administration at 6 mg pyrantel base per pound (the Strongid P double dose) is used. One syringe typically treats up to 1,200 pounds at the standard dose, or about 600 pounds at the double dose. Weigh or estimate weight as accurately as possible to avoid underdosing.

Place the syringe in the interdental space and dispense the paste onto the back of the tongue. Ensure the horse swallows the dose. Deworming frequency should be individualized using fecal egg counts, season, and pasture management. Many programs treat based on veterinary guidance rather than a fixed calendar. Your veterinarian may recommend spring and fall treatments and additional targeted doses depending on fecal results and regional parasite risks.

Do not mix Strongid P for tapeworm with other dewormers in the same administration unless directed. Avoid giving with products containing piperazine due to potential antagonism.

Strengths and Forms

Strongid P paste 43% is supplied as a single-use oral paste syringe with calibration marks. The formulation contains pyrantel pamoate and is flavored to aid acceptance. Each syringe is intended for one horse, adjusted to weight. Availability and packaging may vary by pharmacy and lot.

Missed Dose and Timing

If a scheduled dose is missed in a parasite control program, administer when remembered and resume the program as advised by your veterinarian. For single-dose treatments, give the dose as soon as practical. Do not repeatedly re-dose without guidance. Timing for tapeworm control often aligns with regional recommendations, commonly in cooler seasons when intermediate hosts are active, but follow local veterinary advice.

Storage and Travel Basics

Store Strongid P wormer paste at controlled room temperature, away from excessive heat and freezing. Keep the protective cap on the tip to prevent contamination. Keep out of reach of children and animals. When you travel, keep your paste in the original carton, protected from temperature extremes and direct sunlight. You can store your syringe in a secure, dry compartment to prevent accidental discharge.

Benefits

• Broad-spectrum control against large strongyles, small strongyles, roundworms, and pinworms at the standard dose.
• Tapeworm control when used as a Strongid P double dose, as directed by a veterinarian.
• Palatable, easy-to-administer oral format with clear weight-based markings.
• Suitable for diverse equine management programs when integrated with fecal egg count monitoring.
• Convenient Strongid P wormer paste presentation reduces guesswork for dosing on farm.
• Canadian pricing with US shipping adds access and value for routine care.

Side Effects and Safety

• Most horses tolerate pyrantel pamoate well.
• Mild, temporary effects can include decreased appetite, soft stools, or salivation.
• Horses with heavy parasite burdens may pass visible worms after treatment.
• Hypersensitivity is uncommon but possible with any medication.

Serious reactions are rare. Watch for signs of colic, persistent diarrhea, weakness, or neurologic changes after dosing. Seek veterinary care if concerning signs occur. Use caution in severely ill or debilitated animals and follow veterinary supervision. Do not use in horses known to be allergic to pyrantel compounds.

Drug Interactions and Cautions

Pyrantel may antagonize piperazine; avoid concurrent use unless your veterinarian directs otherwise. Accurate weight-based dosing reduces the risk of underdosing and helps curb resistance. Integrate Strongid P for horses with pasture hygiene, manure management, and fecal egg count testing. Rotate drug classes based on veterinary advice rather than on a fixed calendar alone. Not for human use.

What to Expect Over Time

After dosing, a reduction in fecal egg counts is expected as parasites are expelled. Some horses may pass worms in manure shortly after treatment. Coat condition, weight maintenance, and overall vigor may improve over time with a targeted parasite control plan. Tapeworm control often requires a seasonal or risk-based strategy, typically addressed with a Strongid P for tapeworm double dose when appropriate.

Compare With Alternatives

Veterinarians often consider multiple approved options when designing equine deworming programs. Fenbendazole-based pastes, such as Panacur® Paste, are used for certain parasite indications and may be chosen for specific cases. A daily feed-through pyrantel tartrate, Strongid T®, can be part of a continuous-control strategy under veterinary guidance. Ivermectin- or moxidectin-based products may also be considered for strongyles, bots, or other indications, depending on fecal results and regional patterns.

Patient Suitability and Cost Saving Tips

Strongid P for horses fits many equine management plans. It is useful for herds on pasture-based systems, boarding barns, and individual horses with moderate risk. Horses with unusual medical histories, weight loss, or recurring colic should be assessed before deworming. Very young foals, senior horses, and pregnant mares may need tailored schedules.

• Base treatments on fecal egg counts to avoid unnecessary doses.
• Weigh or tape estimate for accurate dosing and fewer wasted syringes.
• Consider multi-syringe purchases to cover expected seasonal needs.
• Combine treatment with pasture cleanup and composting strategies.
• Set reminders for spring and fall evaluations and rechecks.
• Store your paste properly so it remains effective when needed.

Questions to Ask Your Clinician

• Which parasites are most common on our property, and how should we test?
• Is a Strongid P double dose appropriate for tapeworms in our region?
• How often should fecal egg counts be repeated for this horse?
• Should we rotate to another class, such as fenbendazole or macrocyclic lactones?
• What are the signs that warrant urgent evaluation after deworming?
• How should dosing change for foals, seniors, or pregnant mares?
