Equine Intestinal Worms
Equine Intestinal Worms affect horses of all ages and disciplines. This category helps you compare deworming options by active ingredient, dosage form, and target parasites. It supports barn managers, veterinarians, and owners planning seasonal control and targeted treatment. Stock and packaging can vary by brand and time of year. US shipping from Canada is available for select items, depending on current inventory and regulatory status.What’s in This CategoryThis category includes dewormers across core classes and forms. You will find macrocyclic lactones such as ivermectin and moxidectin, benzimidazoles like fenbendazole, and tetrahydropyrimidines such as pyrantel. Some products combine praziquantel to address tapeworms alongside other species. Forms include oral pastes in graduated syringes, pellets for top-dressing feed, and measured liquid suspensions for precise dosing.Items vary by concentration, spectrum, and intended age groups. Many adult horses need broad coverage for small strongyles, while foals often require focused ascarid control. An ivermectin horse dewormer is common for bots and several nematodes, while moxidectin is often reserved for specific scenarios. Pelleted formulas support groups or picky eaters. Pastes work well for individual dosing when exact weight-based calculations matter.Packaging ranges from single-dose syringes to multi-dose containers. Some tubes include adjustable plunger stops for weight settings. Pellets and suspensions can simplify barn routines during busy periods. You can compare label indications, withdrawal guidance, and typical use patterns before selecting a product for your program.How to ChooseStart with fecal egg counts to inform timing and product choice. Test results help identify high shedders and reduce unnecessary treatments. Consider age, weight, pasture pressure, and prior use history when selecting an active ingredient. Aim to reduce resistance by relying on diagnostics and evidence rather than habit or calendar alone. Rotational deworming for horses may still appear in some programs, but most experts now favor targeted approaches guided by testing.Match the form to the handler and horse. Pastes offer accuracy for individual horses. Pellets can help with barn-wide administration. Suspensions allow consistent dosing when using a scale or dose syringe. Confirm any pregnancy or foal safety notes on the label. Review storage and stability; many products keep best at room temperature and away from heat or freezing. Avoid repeated use of one class without diagnostic support. Typical pitfalls include under-dosing, guessing weight, and skipping follow-up fecal tests.Confirm weight accurately; use a scale or tape.Recheck fecal egg counts after treatment if advised.Match ingredient to target species and season.Store products per label to preserve potency.Popular OptionsSeveral products represent common choices for everyday parasite control. Panacur Paste contains fenbendazole, a benzimidazole used for many roundworms. It fits programs that require flexible dosing and careful weight-based administration. For certain encysted small strongyle scenarios, clinicians may consider specific dosing protocols. Always confirm label directions and consult a professional when planning intensive regimens. In this context, a pyrantel pamoate horse dewormer offers an alternative class for rotation guided by diagnostics.Strongid P Paste provides pyrantel pamoate in an easy-to-use syringe. Many handlers prefer its straightforward dosing for adult horses and appropriate juveniles. It can complement a test-based plan that spaces treatments based on shedding status. When feed-based dosing is practical, a liquid option can help. For example, you can review pyrantel pamoate suspension for horses at Strongid T to compare form and instructions. You may also review Strongid P Paste and Panacur Paste when assessing class and dosage preferences across your herd.Related Conditions & UsesCommon targets include small strongyles and large strongyles, which can damage the intestinal tract and impair condition. Adult horses often harbor small strongyles with variable egg shedding. Foals and yearlings face higher risk from ascarids, which can cause cough, ill thrift, and impaction. Pinworms may drive tail rubbing and skin irritation around the dock. Bots relate to fly seasons and require attention during appropriate timing windows for best impact.Tapeworms can contribute to colic risk in some regions and cases. Many programs add seasonal or test-guided coverage using praziquantel combinations. Use tapeworm treatment for horses only as indicated and at label doses. Fecal egg counts and, when applicable, other diagnostics support smarter intervals between treatments. Coordinating with a veterinarian helps align product selection with pasture hygiene, manure management, and hay or turnout patterns for a comprehensive plan.Authoritative SourcesEvidence-based guidelines evolve as resistance patterns change.

Frequently Asked Questions
Do I need a prescription for horse dewormers?
Many equine dewormers are available without a prescription, but rules can vary by product and jurisdiction. Check the label and any local regulations before purchasing. Some formulations or concentrations may be restricted or require veterinary guidance. When in doubt, ask a veterinarian to confirm suitability for your horse’s age, weight, and use case. Keep records of treatments and test results for better long‑term planning.
How do I choose the right active ingredient?
Start with fecal egg counts and discuss results with a veterinarian. Match the ingredient to target species, season, and local resistance concerns. Consider past exposure and recent treatments to avoid repeating one class unnecessarily. For foals and high shedders, tailor timing and follow-up testing. Select a form your horse accepts reliably, and dose accurately based on current weight.
Can I buy for foals or pregnant mares?
Some products are labeled for use in foals and pregnant mares, while others are not. Always review the label and any manufacturer guidance before dosing. Use accurate weights, and consider recent health status and concurrent medications. When planning for foals, confirm age-appropriate timing and monitoring. For pregnant mares, verify safety data and consult a veterinarian for individualized recommendations.
How should I store equine dewormers?
Most products store at room temperature away from heat, freezing, and direct sunlight. Keep syringes capped and pellets or liquids sealed to prevent contamination. Avoid humid tack rooms or transport trailers that get hot or cold. Check expiration dates before use, and discard outdated items. Follow any disposal guidance on the label or local regulations to protect animals and the environment.
How often should I deworm my horse?
Frequency depends on fecal egg counts, season, and regional risk. Many programs test, treat high shedders as needed, and reassess later. Broad calendar-based routines are less favored due to resistance concerns. Work with a veterinarian to time treatments for bots, ascarids, and strongyles. Keep records to refine intervals and adjust products based on outcomes and current guidelines.
