Prescribing overview
Pamoate paste and tartrate medicated feeds are different preparations, not volume-equivalent substitutes.
Key prescribing checks
- Select by species, exact product and target parasites. Equine labeling does not establish a companion-animal administration plan.
- Parasite coverage is limited to the product’s claims; pyrantel is not a universal answer to every worm or protozoal infection.
- Base versus salt strength and concentration need explicit reconciliation. Do not translate a volume from one suspension, paste or feed formulation to another.
Uses by species
Approval and evidence apply to the named product, species, route and indication. An extra-label use requires its own prescribing assessment; a human indication is not an animal approval.
Horses and ponies
US FDA-approved Strongid PasteRemoval/control of mature large strongyles, small strongyles, pinworms and large roundworms
Coverage depends on parasite species and stage.
Use / indication source ↗Pharmacology & pharmacokinetics
Mechanism and clinical role
The verified paste contains pyrantel pamoate, with strength expressed as pyrantel base.
Absorption, distribution, metabolism and elimination
The reviewed equine paste label does not establish quantitative absorption or elimination parameters.
SAFETY REFERENCE · PRODUCT & SPECIES SPECIFIC
Contraindications & cautions
Contraindications identify circumstances where the source says a product should not be used. Precautions call for assessment or monitoring. Interactions identify combinations to review. They are distinct categories; this summary does not replace a full interaction check or the current product label.
Strongid Paste
Pyrantel pamoate oral paste; Horses
Contraindications · when not to use
A formal contraindication list is not established in the reviewed source for this scope. This does not establish safety; confirm the exact product and full labeling.
Precautions & monitoring
- Label warning: avoid severely debilitated animals; do not use in horses intended for human consumption.
Strongid C
Equine pyrantel tartrate feed pellets; exact named-product label pending
Contraindications · when not to use
A formal contraindication list is not established in the reviewed source for this scope. This does not establish safety; confirm the exact product and full labeling.
Precautions & monitoring
- Exact Strongid C package label remains unverified. Related FDA pyrantel-tartrate feed labeling cautions about severe debilitation and excludes food horses; do not assume equivalence.
Strongid T
Canadian equine pyrantel pamoate suspension; safety-label verification incomplete
Contraindications · when not to use
A formal contraindication list is not established in the reviewed source for this scope. This does not establish safety; confirm the exact product and full labeling.
Precautions & monitoring
- Canadian product identity verified; full official package safety label could not be retrieved. Obtain current local label before use.
Absent contraindication text here is a label-data gap, not evidence of unrestricted safety. Strongid products differ in salt and formulation.
Safety sources checked: . Selected label information; independent veterinary or veterinary-pharmacy review remains pending. A label for dogs, cats, horses or humans does not establish safety for another species.
Adverse effects
A detailed adverse-event frequency table is not supplied; this is not evidence that reactions cannot occur.
These are selected source-reported effects, not incidence estimates or an exhaustive list. Spontaneous postmarketing reports do not by themselves establish frequency or causality.
Dosing & administration
| Species & indication | Labeled regimen | Eligibility & source |
|---|---|---|
| Horses and poniesLabel-listed mature nematode infectionsStrongid Paste, 180 mg pyrantel base/mL | 3 mg pyrantel base/lb body weight Oral · Single dose One administration; repeat schedule is age/reproductive-status specific | Use current weight and syringe markings. Do not use in food horses; avoid severely debilitated animals. Verify full dosing label ↗ |
Label repeats: foals 2–8 months every four weeks; older horses every six weeks; mares one month prefoaling and 10–14 days postpartum. Veterinary parasite assessment remains essential.
No Strongid C or Strongid T dose is verified here.
Extra-label prescribing and food-animal residue requirements are separate from labeled regimens. FDA extra-label-use guidance ↗
Drug & supplement interactions
This is a selected interaction reference, not an automated or comprehensive combination checker. Reconcile prescription drugs, nonprescription products, supplements and recent treatment changes.
Strongid C
Equine pyrantel tartrate feed pellets; exact named-product label pending
- Related feed label prohibits mixing with bentonite.
Monitoring
Use fecal testing and post-treatment efficacy assessment to detect resistance.
Client counseling
Deliver onto the tongue and confirm the complete dose is swallowed; avoid underdosing.
This section supports the veterinary team's discharge discussion; it does not replace the product’s Client Information Sheet where one is required.
Storage & handling
Store paste at 15–25°C; replace syringe cap after partial use.
Brands, formulations & ingredient identity
Active ingredients
Pyrantel
Other searchable names: pyrantel pamoate · pyrantel tartrate
Strongid Paste contains pyrantel pamoate; Strongid C contains pyrantel tartrate. Salt, concentration, vehicle and use instructions differ.
Strongid T is a pyrantel pamoate suspension; the linked Canadian regulatory record establishes that named product’s identity. Check jurisdiction and the actual container.
Products combining pyrantel with other antiparasitics are separate ingredient combinations, not synonyms for pyrantel alone.
Shared ingredients do not establish interchangeable concentrations, routes, release properties, species labeling or regional availability.
