Panacur® Paste for Horses

Panacur Paste is a fenbendazole dewormer formulated for horses. It helps control common internal parasites with an easy-to-use oral syringe. With US delivery from Canada and access to Canadian pricing, this trusted option makes routine equine parasite control straightforward.

What Panacur® Is and How It Works

Panacur® Paste contains fenbendazole, a broad-spectrum benzimidazole anthelmintic used in equine parasite control. Fenbendazole inhibits parasite microtubule formation and energy metabolism, which ultimately interrupts vital functions and eliminates susceptible gastrointestinal worms.

Fenbendazole comes in several veterinary formats. Some programs use Panacur Suspension in herd settings or Panacur Aquasol where flock or flock-to-household treatment is appropriate. The paste syringe remains a mainstay for individual horses because dosing can be precisely set to body weight.

Who Panacur Is For

This paste is indicated for horses requiring treatment and control of common internal parasites such as small and large strongyles, pinworms, and ascarids as indicated on the product label. It is widely used in both adult horses and foals as part of a veterinarian-guided parasite control program. Use in species outside the label should be determined by a veterinarian.

For dogs, fenbendazole is commonly provided as granules rather than paste; options such as Panacur Granules 22 2 may be recommended when appropriate. In equine programs, other dewormer classes can be considered at different times of year to address resistance patterns; some caretakers discuss pyrantel options such as Strongid T with their veterinarian.

Horses with known hypersensitivity to fenbendazole should not receive this medicine. Caution is advised in severely debilitated or heavily parasitized animals, where careful veterinary supervision is important during treatment.

Dosage and Usage

Use a veterinarian-guided plan based on fecal egg counts, regional risk, and the horse’s age and management. Determine the horse’s weight accurately, then adjust the paste syringe to the prescribed dose. Place the syringe tip in the interdental space, deposit paste onto the back of the tongue, and allow the horse to swallow. Ensure the full dose is delivered.

Protocols vary by target parasites and farm epidemiology. Some horses receive a single treatment, while others use a multi-day regimen when directed by a veterinarian. Always follow the label and veterinary instructions to achieve adequate exposure time and to reduce the risk of suboptimal control.

Strengths and Forms

Panacur Paste is commonly supplied as a fenbendazole 10% oral paste in a calibrated syringe suitable for weight-based dosing. Syringes are typically available in a single-use size with a plunger graduated to typical equine weight ranges. Availability and packaging may vary by dispensing pharmacy.

Missed Dose and Timing

For programs that call for a single administration, give the dose on the planned day. If a multi-day regimen is prescribed and a dose is missed, administer it when remembered unless it is close to the next scheduled dose; do not double dose. Resume the regular schedule and contact the prescribing veterinarian if multiple doses are missed or if there is uncertainty about how to proceed.

Storage and Travel Basics

Store the paste in its original packaging at controlled room conditions away from direct heat and sunlight. Keep the cap secured and the plunger locked until use. Do not allow contamination of the syringe tip. For travel, pack the syringe in a clean, sealed bag and protect it from temperature extremes, crushing, and moisture. Keep out of reach of children and animals.

Temperature-sensitive items ship with cold-chain handling and insulated packaging. While the paste is typically stable under labeled storage conditions, follow any storage guidance provided by the dispensing pharmacy.

Benefits

• Broad-spectrum control of labeled equine gastrointestinal parasites.
• Weight-calibrated syringe helps deliver accurate dosing for individual horses.
• Well-established safety profile when used as directed and at labeled doses.
• Fits selectively targeted deworming strategies based on fecal egg counts.
• Non-invasive, oral formulation that most horses accept when administered properly.

Side Effects and Safety

• Most horses tolerate fenbendazole well with no notable adverse effects.
• Occasional transient soft stool or mild digestive upset can occur.
• Rare hypersensitivity reactions may present with hives, facial swelling, or difficulty breathing; urgent veterinary care is warranted if these appear.
• In heavily parasitized animals, worm die-off can be associated with discomfort or colic; close monitoring under veterinary guidance is recommended.

Do not use in animals with known sensitivity to fenbendazole. Use caution in debilitated horses, and follow a veterinarian’s advice when combining anthelmintics or when treating during high parasite burdens. Report any unexpected reaction to the prescriber and the dispensing pharmacy.

Drug Interactions and Cautions

• Concurrent use with other dewormers or off-label combinations should be directed by a veterinarian.
• Follow species- and region-specific withdrawal and competition rules per the product label and regulatory guidance.
• Integrate treatment with pasture hygiene, manure management, and fecal testing to slow resistance.
• Always verify the correct species and weight before dosing.

What to Expect Over Time

When used as part of a selective deworming plan, fecal egg counts commonly decline after appropriate treatment, and clinical signs related to susceptible parasite burdens may improve. Long-term control depends on many factors, including pasture management, seasonal transmission patterns, and resistance on the farm. Veterinarians may recommend periodic fecal egg count reduction tests to confirm effectiveness and adjust protocols as needed.

Compare With Alternatives

Different anthelmintic classes are used across the year to address local resistance and parasite risks. Pyrantel-based options such as Strongid P are often considered as part of rotation strategies. For dogs and cats, multi-worm coverage products like Drontal Plus may be used when appropriate. For additional background on companion-animal tapeworm care, see this overview on Tapeworm Treatment.

Availability and Substitutions

Availability may vary by dispensing pharmacy. If a specific presentation is temporarily unavailable, a prescriber may recommend a suitable alternative in the same class or another approved dewormer based on the horse’s needs and fecal testing results.

Patient Suitability and Cost-Saving Tips

Ideal candidates include horses in managed deworming programs guided by fecal egg counts and local risk. Animals with severe illness, heavy parasite loads, or known fenbendazole sensitivity require close veterinary oversight. To save on costs, consider ordering multiple syringes when appropriate for the stable’s needs, set refill reminders aligned with the deworming calendar, and coordinate treatments across the barn to streamline shipping and supplies.

Questions to Ask Your Clinician

• Which parasites are most relevant for this horse based on fecal egg counts and season?
• Is a single treatment or a multi-day regimen recommended for the current findings?
• How soon should a fecal egg count reduction test be performed after treatment?
• What signs should be monitored in horses with heavy parasite burdens?
• How should this product fit with other dewormer classes on the farm?
• Are there any competition or withdrawal considerations to follow?
