Panacur Paste for Horses

This equine dewormer contains fenbendazole for broad gastrointestinal parasite control in horses. It is widely used during strategic deworming programs guided by fecal egg counts. This page explains how it works, how to use it, and how to store it safely.

What Panacur Is and How It Works

Panacur Paste® contains fenbendazole, a benzimidazole anthelmintic that disrupts parasite energy metabolism. It targets adult and larval stages of many equine nematodes in the gut. You can order with US delivery from Canada through our platform, which supports barn and household planning. This can help manage out-of-pocket costs without insurance when allowed.

CanadianInsulin.com is a prescription referral platform. We verify prescriptions with your prescriber when required, and licensed Canadian pharmacies dispense your order.

Used as directed, panacur for horses treats large strongyles, small strongyles, pinworms, and ascarids per the label. The treatment works in the gastrointestinal tract and is given by mouth. It is not absorbed extensively, which limits systemic exposure. Always follow the current product label for species and indication.

Who It’s For

Fenbendazole paste for horses is indicated for the treatment and control of common equine gastrointestinal worms. It may be used in foals, yearlings, mares, and stallions when the label permits. Your veterinarian may tailor timing based on fecal egg counts, age, and pasture risk.

Do not use this medicine in any species or situation not listed on the label. Avoid use if a horse has a known hypersensitivity to any ingredient. If a horse is severely debilitated or shows signs of colic, seek veterinary advice before dosing.

To learn more about target parasites and control strategies by species, see the overview in Equine Intestinal Worms. Households with dogs or cats may want to review Canine Intestinal Worms and Feline Intestinal Worms for species-specific guidance.

Dosage and Usage

Follow the on-label dose based on accurate body weight. Standard single-dose schedules are used for many adult strongyles and pinworms. A multi-day regimen is often used for encysted small strongyles and ascarids in young horses. The exact schedule should follow the manufacturer’s label or your veterinarian’s instructions.

Before dosing, confirm the horse’s weight using a scale or weight tape. Set the syringe dial to the correct weight mark. Place the nozzle into the interdental space, aim over the back of the tongue, then depress the plunger. Raise the head for a few seconds to encourage swallowing. Offer a small amount of feed after dosing if appropriate. Avoid spilling paste on feed buckets or stall surfaces where dosing accuracy can be lost.

Programs that include the 5-day PowerPac regimen can address encysted cyathostomes when recommended. Use powerpac horse wormer only according to the label and veterinary guidance. After you give a dose, keep records of date, product, and lot number for your barn log. Keep other dewormers separate and do not mix products without veterinary advice.

Strengths and Forms

This product is typically supplied as a 10% oral paste for equines in a graduated syringe. Each syringe is designed to dose multiple weight bands. The paste is flavored for palatability and intended for oral use only.

Availability may vary by supplier. Some markets offer a multi-syringe kit for extended regimens. Check current stock for panacur equine paste and confirm packaging before you order. Always review the label in the box you receive, as regional labeling can differ.

Missed Dose and Timing

If you miss a scheduled day in a multi-day course, give the dose when you remember the same day if possible. Then resume the original schedule. Do not double up doses at the next administration without veterinary advice. For single-dose treatments, speak with your veterinarian if the timing overlaps with a planned rotation.

If a horse spits out a substantial portion, contact your veterinarian about whether to redose. Keep in mind that barn hygiene, manure removal, and pasture rotation matter as much as panacur wormer timing. Maintain consistent fecal egg count testing to guide future deworming intervals.

Storage and Travel Basics

Store the syringe at room temperature as directed on the label. Protect it from freezing and excessive heat. Keep the cap on the nozzle when not in use and store out of reach of children and animals. Do not puncture or cut the syringe.

When traveling to shows or events, keep the product in its original carton for identification. Pack the box in a clean, dry container away from direct sunlight. Bring dosing records and the box label in case verification is needed. If you are flying, check carrier rules for animal health supplies. You can browse related animal treatments in Pet Medications for trip planning.

Benefits

This medicine provides broad-spectrum control against many equine nematodes. It is orally administered, which helps dosing in barns without injection access. The paste’s marked syringe makes weight-based dosing straightforward. Programs that include multi-day regimens may address encysted stages when recommended.

Rotational strategies guided by fecal testing can limit resistance pressure. Your veterinarian can help align dosing windows with pasture management and regional parasite risk.

Side Effects and Safety

• Mild, transient soft stools
• Temporary decreased appetite
• Salivation after dosing
• Occasional gagging or paste expulsion

Serious effects are uncommon. However, rapid parasite kill in heavily burdened horses can rarely trigger colic signs or impaction. Hypersensitivity reactions are possible with any medicine. If a horse shows severe discomfort, swelling of the lips or face, breathing issues, or persistent colic signs, seek veterinary care. Discuss pregnancy and breeding use with your veterinarian and follow the label.

Drug Interactions and Cautions

Fenbendazole has few known clinically significant interactions in horses. Avoid combining with other dewormers in the same session unless a veterinarian recommends it. Do not exceed the labeled dose. Monitor fecal egg counts to evaluate response and adjust the deworming plan over time.

Use caution in debilitated animals. Treating during ongoing colic should be done under veterinary supervision. Maintain routine dental care and nutrition, which support gut health during parasite control.

What to Expect Over Time

After dosing, manure may appear unchanged, and worms are not always visible. Fecal egg counts typically guide whether the program is effective. Your veterinarian may recommend retesting weeks after treatment to check reduction levels. Barns often adjust intervals seasonally based on pasture contamination and weather.

Consistent record-keeping helps spot patterns. Note product, date, horse weight, and fecal results. Good manure management and pasture rotation can reduce the need for frequent treatments. Ensure each horse receives its full dose without sharing syringes between animals.

Compare With Alternatives

Another equine dewormer class is pyrantel. You can review paste formulations such as Strongid P when discussing rotation plans with your veterinarian. For feed-based programs, tartrate forms like Strongid T may be considered under veterinary guidance. Do not combine products without professional advice.

Pricing and Access

We list transparent cash pricing so you can review options before checkout. Many customers compare barn-wide quantities and schedule refills together. This can help reduce per-horse costs over a season. Ordering supports US shipping from Canada, which may provide value compared with local retail.

For cost planning, discuss fecal testing intervals, rotation, and timing with your veterinarian to minimize unnecessary treatments. If you prefer another class, search our categories for additional choices.

For convenience, you can also explore small-animal options if your barn has dogs or cats. Tablets and topicals in other species include resources like Drontal, Drontal Plus, and Milbemax when indicated for those animals. Always use species-specific products as labeled.

Availability and Substitutions

Stock can vary. If this item is unavailable, a veterinarian may recommend another approved equine anthelmintic. Do not substitute with a product intended for a different species or formulation without guidance. Check the label each time you receive a shipment, as packaging and instructions may change.

Patient Suitability and Cost-Saving Tips

This treatment may suit most healthy horses requiring routine parasite control. Horses with heavy burdens or prior colic should be evaluated by a veterinarian before starting a multi-day regimen. Foals and pregnant mares should be treated only as directed by the label and your veterinarian.

To manage costs, coordinate multi-horse orders and keep a shared dosing calendar. You can set reminders so you do not miss scheduled doses in a multi-day plan. Buying enough for the full course helps avoid gaps. Keep syringes labeled by horse name to prevent mix-ups.
