Clean Sweep Dewormer

Clean Sweep Dewormer is a dual-ingredient liquid dewormer combining fenbendazole (50 mg/mL) and pyrantel pamoate (40 mg/mL) for dogs, cats, goats, sheep, and cattle. Fenbendazole works by disrupting the internal structure parasites need to absorb nutrients, slowly starving them over a multi-day course, while pyrantel works faster by paralyzing the muscles of roundworms and hookworms so they’re expelled in the stool within a day or two — combining the two gives broader coverage across parasite species and life stages than either ingredient alone. Because it’s a ready-to-use liquid, Vetgrade.com’s Clean Sweep Dewormer is easy to dose accurately by weight with an oral syringe.

Animals It’s Used For

Dogs & Cats

Used for roundworms, hookworms, whipworms, and certain tapeworm species, with pyrantel adding faster knockdown of roundworms and hookworms specifically.

Goats, Sheep & Cattle

Used for gastrointestinal roundworms (strongyles) and other susceptible parasites at pasture. Important: because these are food-producing species, confirm the withdrawal period with your veterinarian before treating any animal intended for meat or dairy — see the FAQ below.

Symptoms & Indications

If your animal is experiencing any of the following, internal parasites may be present:

• Vomiting
• Diarrhea
• Weight loss
• Poor coat condition
• Lethargy
• Reduced appetite
• Scooting (dogs)
• Visible worms in stool
• Pot-bellied appearance (young animals)
• Coughing (in migrating larval infections)

Early intervention helps prevent nutrient loss, growth delay, and secondary infections.

Important Safety Notes

Pyrantel runs above its typical standalone dose in dogs and cats. At the volume needed to correctly dose fenbendazole in dogs and cats, the pyrantel component comes out well above its usual standalone target dose. Pyrantel pamoate is widely regarded as one of the gentler, wider-margin dewormers available, so this isn’t expected to be dangerous, but it’s a real deviation from independently studied dosing and worth mentioning to your veterinarian, especially for very young, small, or debilitated animals.

Fenbendazole and pyrantel target different parasites at different strengths. Neither ingredient alone provides complete coverage of every parasite listed — for example, tapeworm coverage depends on species and isn’t guaranteed with every course.

Not a substitute for fecal testing in recurring cases. If symptoms persist or recur after treatment, a veterinary fecal exam helps identify whether a different or resistant parasite is involved.

Avoid in severely debilitated or dehydrated animals without veterinary guidance, and use caution in very young puppies, kittens, and neonatal livestock.

Clean Sweep Dewormer Dosing Chart

Doses below reflect commonly referenced veterinary ranges and are for general informational purposes. Always confirm exact dosing and treatment length with a veterinarian.

Cattle being treated for tapeworms or Type II ostertagiasis (inhibited larvae) sometimes need roughly double the standard livestock rate (~0.1 mL per lb) per established fenbendazole protocols — confirm with your veterinarian if either of those is the specific concern.

Dosing Instructions

1. Shake the bottle thoroughly before each use to ensure a completely uniform solution.
2. Weigh the animal (or use a recent known weight) for accurate dosing.
3. Using a calibrated oral syringe, measure the exact fluid volume required for the species being treated.
4. Administer directly into the mouth, or mix thoroughly into a small portion of wet food or feed that will be consumed promptly.
5. For dogs and cats, give once daily for 3 consecutive days, then retreat in 2–3 weeks to catch newly hatched larvae from the parasite’s life cycle.
6. For goats, sheep, and cattle, give as a single dose, and retreat at 14 days only if reinfestation or a heavy burden is confirmed.
7. If treating goats, sheep, or cattle intended for meat or dairy, confirm the withdrawal period with your veterinarian before treatment.

FAQs

Can Clean Sweep Dewormer be used in pregnant or nursing animals?
Fenbendazole is generally considered one of the safer dewormers in pregnancy across several species, but safety hasn’t been specifically established for this combination product. Confirm with your veterinarian before treating a pregnant or nursing animal.

Is there a withdrawal period for goats, sheep, or cattle raised for meat or dairy?
Yes. Fenbendazole’s published withdrawal periods for cattle, sheep, and goats commonly run several days depending on the specific product and dose used, and can be longer for higher doses used against inhibited larvae or tapeworms. Always confirm the current withdrawal interval with your veterinarian or FARAD before treating any animal intended for meat or milk.

Why does my dog need three days of treatment when some dewormers are a single dose?
Fenbendazole works over several days to affect parasites at different stages of their life cycle, which is why the standard course is three consecutive days rather than one. The livestock dose is different — usually a single dose — because it targets a different mix of parasites at lower per-body-weight requirements.

Why retreat in 2–3 weeks for dogs and cats but 14 days for livestock?
Both timelines are aimed at catching parasites that were too immature to be killed by the first treatment and have since matured. The exact window differs somewhat by species and the typical parasite life cycles involved in each.

Does this treat tapeworms?
Fenbendazole covers certain tapeworm species, but not all — coverage depends on the specific tapeworm involved. If tapeworms are suspected or confirmed, ask your veterinarian whether additional coverage (such as a praziquantel-based product) is needed.

My pet’s worms came back after treatment — did it not work?
Not necessarily. Reinfection is common in outdoor or multi-animal environments, and some parasite eggs can persist in soil for a long time. A fecal exam can confirm whether it’s reinfection with the same parasite, a different parasite, or resistance, which helps guide next steps.

How should it be stored, and what’s the shelf life?
Store at room temperature, out of direct sunlight, tightly capped. Shake before each use. Discard if the solution changes color, smells off, or is past the expiration date on the bottle.
