Panacur® Suspension for Dogs and Cats

Panacur® Suspension is an oral dewormer for dogs and cats. It helps manage common intestinal parasites and supports broader parasite control plans set by your veterinarian. This page explains uses, dosing basics, and how to order with US delivery from Canada, plus typical options that may apply without insurance.

What Panacur Is and How It Works

Panacur is the brand name for fenbendazole, a broad-spectrum anthelmintic. As a fenbendazole suspension, it works by disrupting parasite microtubules, which interferes with energy use and leads to parasite death. It targets several intestinal nematodes and may be used as part of a comprehensive parasite management program, including fecal testing and environmental control. Always follow your veterinarian’s guidance for species and age-specific use.

Who It’s For

This medicine is used for canine and feline intestinal nematodes such as roundworms and hookworms. It may also be used for Giardia management in dogs when recommended by a veterinarian. For condition details, see Roundworm Infection, Hookworm Infection, and Pet Giardiasis.

Use the fenbendazole suspension for dogs and cats only as directed. Very young, debilitated, or pregnant animals require veterinarian oversight. Discuss prior deworming history, current flea control, and any previous adverse reactions before starting treatment.

Dosage and Usage

Shake the bottle well before each use. Your veterinarian will provide dosing based on species, body weight, and target parasites. Many protocols involve once-daily administration for several consecutive days. Some pets require repeat courses depending on exposure risk and fecal test results.

Measure liquid with a marked oral syringe for accuracy. Give the dose by mouth; you may mix with a small amount of food if directed. Ensure your pet consumes the full amount. Continue through the full course even if stools look normal sooner. The panacur oral suspension is often part of a broader plan that can include flea control and environmental cleaning to reduce reinfection.

Strengths and Forms

This treatment is supplied as an oral liquid in a calibrated bottle. A commonly published concentration is 100 mg/mL fenbendazole. Package sizes can vary by market and supplier. Availability may differ based on region and veterinary practice preference.

Some veterinarians provide guidance on panacur liquid for cats when appropriate, while others may recommend different formulations. If you need an alternative format, ask your prescriber about granules or paste options offered under the same drug class.

Missed Dose and Timing

If you miss a dose, give it when remembered unless it is close to the next scheduled time. Do not double the next dose. Resume the regular schedule and complete the course as advised by your veterinarian.

For young pets, such as those on panacur suspension for kittens or puppies, consistent daily timing across the multi-day course helps maintain coverage. Set reminders to keep doses on track.

Storage and Travel Basics

Store the bottle at room temperature away from moisture and direct light. Keep the cap tightly closed. Shake well before each use. Do not freeze unless labeling specifically allows it. Keep out of reach of children and animals.

When you travel, keep the medicine in its original packaging with the label visible. Pack an oral dosing syringe and a small amount of the pet’s regular food for easier administration. If crossing borders or flying, carry a copy of the prescription or a veterinarian note in your travel documents. Secure the bottle upright to prevent leakage.

Benefits

This medicine can cover multiple intestinal nematodes in one course. Liquid dosing allows weight-based adjustments by your veterinarian. It can be given directly by mouth or with a small amount of food when appropriate. Label-guided use and fecal testing help confirm treatment goals.

Side Effects and Safety

• Gastrointestinal upset: mild vomiting or soft stool
• Temporary decrease in appetite
• Drooling or hypersalivation in some cats
• Lethargy that usually resolves after dosing ends

Serious reactions are uncommon but can include persistent vomiting, diarrhea, or signs of allergic response such as facial swelling or hives. Seek veterinary care if symptoms are severe or do not improve. Stools may contain dead or dying parasites after treatment. Discuss tapeworm coverage with your veterinarian; this class may not address all tapeworm species. For tapeworm details, see Tapeworm Infection.

Drug Interactions and Cautions

Tell your veterinarian about all current medicines, supplements, and preventives. Concurrent anthelmintics, certain flea/tick products, or recent deworming history can influence timing and selection. Use caution in pets with known hypersensitivity to benzimidazole compounds. Follow label directions and veterinary guidance for pregnant or lactating animals.

If vomiting occurs soon after dosing, ask your veterinarian whether to repeat the dose. Do not change the dose or duration without professional advice.

What to Expect Over Time

With appropriate use, stools may normalize as the parasite burden falls. Some pets require follow-up fecal testing to confirm results. Reinfection can occur, especially in environments with contaminated soil or untreated household pets. Pair treatment with hygiene steps such as prompt feces removal and effective flea control when tapeworm risk exists.

Adherence matters. Set daily reminders, track doses on a calendar, and schedule follow-up testing when recommended. Your veterinarian may adjust future courses based on exposure, age, and season.

Compare With Alternatives

For broader parasite coverage, your veterinarian may consider other approved dewormers. Products that combine multiple actives can address additional species in a single course. Two commonly used options include Drontal Plus for mixed intestinal parasites and Droncit for tapeworms. For background reading on tapeworm therapy, see our article Tapeworm Treatment.

Availability and Substitutions

Supply can vary by region and season. If this item is temporarily unavailable, your prescriber may recommend a comparable anthelmintic or a different formulation. Do not switch products without veterinary approval, since parasite coverage differs across classes.

Patient Suitability and Cost-Saving Tips

This treatment may suit dogs and cats needing nematode control or Giardia support under veterinary supervision. Pets with prior reactions to benzimidazoles, severe illness, or unusual dietary restrictions require extra caution. Always discuss age, pregnancy status, and concurrent preventives before starting.

To reduce costs, ask about multi-pet or multi-month plans and coordinate refills with routine fecal testing. Set refill reminders to avoid treatment gaps. Combining deworming with environmental control and monthly preventives can reduce reinfection and limit repeat courses.
