Panacur® Suspension for Dogs and Cats

Panacur® Suspension is a broad-spectrum veterinary dewormer containing fenbendazole for dogs and cats. It targets roundworms, hookworms, whipworms, and certain tapeworms, and is often used for Giardia support under veterinary direction. Available from Canada with US delivery from Canada, this suspension offers dependable access at Canadian pricing for routine parasite control. Explore more options in Pet Medications.

What Panacur® Is and How It Works

Panacur® Suspension belongs to the benzimidazole class of anthelmintics. Fenbendazole binds to parasite tubulin, disrupting microtubule formation, glucose uptake, and critical energy pathways. This leads to death of susceptible gastrointestinal parasites, including common roundworms (Toxocara spp., Toxascaris leonina), hookworms (Ancylostoma spp., Uncinaria stenocephala), whipworms (Trichuris vulpis), and some tapeworms (Taenia spp.). Veterinarians also use fenbendazole as part of Giardia management protocols in dogs.

The suspension is given by mouth, typically with a small meal to improve acceptance. Treatment courses are short and may be repeated depending on the parasite lifecycle and local veterinary guidance. Many families pay cash for routine deworming, and having a suspension form can make dosing straightforward for pets that dislike tablets.

Who Panacur® Is For

This medicine is intended for dogs and cats diagnosed with or at risk for susceptible intestinal parasites. It is commonly used for puppies and kittens, adult pets, multi-pet households, and shelter or rescue settings where parasite pressure can be higher.

Use may be limited or require veterinary oversight in the following situations:

• Known hypersensitivity to fenbendazole or other benzimidazoles
• Severely debilitated, underweight, or dehydrated animals
• Very young puppies or kittens when label or veterinary guidance recommends waiting
• Pregnant or lactating animals, unless a veterinarian advises an appropriate protocol
• Pets with significant liver, kidney, or gastrointestinal disease

Always follow the label and a veterinarian’s instructions for species, weight, and indication.

Dosage and Usage

Label dosing is based on body weight and indication. Veterinarians commonly calculate fenbendazole at mg/kg and adjust the course length for the target parasite. Typical guidance includes short daily courses for intestinal worms and, when used for Giardia, a multi-day course with hygiene and environmental control. Shake the bottle well before measuring each dose.

• Give by mouth. Many labels suggest administering with a small amount of food.
• Measure carefully using an oral syringe or dosing cup to match the pet’s weight.
• Complete the full course even if stools improve sooner; repeating a course may be recommended depending on the lifecycle.
• For households with multiple pets, a veterinarian may advise treating all exposed animals and cleaning living areas thoroughly.
• For tapeworms, control of fleas and prey exposure is important. If Dipylidium tapeworms are suspected, a praziquantel‑containing product may be preferred.

If uncertain about dose or duration, defer to a veterinarian and the product label.

Strengths and Forms

Panacur® Suspension is commonly available as oral suspensions in concentrations often published as 10% (100 mg/mL) or 2.5% (25 mg/mL). Bottle sizes vary by market. Availability may differ by species labeling and country. Other fenbendazole presentations include Panacur Paste and Panacur Granules, which some pets may prefer.

Missed Dose and Timing

If a dose is missed, give it when remembered unless it is close to the next scheduled dose. In that case, skip the missed dose and resume the regular schedule. Do not double up. Maintaining consecutive daily doses during a course helps ensure effectiveness.

Storage and Travel Basics

Store the suspension at controlled room temperature as indicated on the label, protected from moisture and excessive heat. Keep the cap tightly closed and the bottle upright. Do not use past the expiration date. Keep out of reach of children and animals.

• For travel, pack the bottle in a sealed bag, keep it upright, and carry a copy of the prescription if available.
• Avoid leaving medicines in vehicles where temperatures can rise or drop.
• Use original packaging and labeling to avoid confusion during trips.

Benefits

• Broad-spectrum activity against common canine and feline intestinal worms
• Liquid suspension allows weight‑based dosing and easy administration for many pets
• Flexible use in multi-pet households and rescue settings
• Often included in Giardia management plans under veterinary direction
• Trusted benzimidazole class with decades of veterinary use

Side Effects and Safety

• Most pets tolerate fenbendazole well; mild, transient gastrointestinal upset can occur
• Occasional vomiting, soft stool, diarrhea, or decreased appetite
• Hypersalivation or drooling in some cats due to taste
• Lethargy or mild lethargy reported in rare cases
• After deworming, passing worms or worm fragments may be seen in stool

Serious reactions are uncommon. Rarely, allergic‑type signs related to parasite die‑off may appear, including facial swelling, hives, or breathing difficulty. Discontinue and seek veterinary care if severe or unusual signs occur. Pets with heavy parasite burdens may need additional supportive care and environmental cleaning.

Drug Interactions and Cautions

Clinically significant drug interactions with fenbendazole are not commonly reported in companion animals. Use caution when combining anthelmintics without veterinary oversight, and inform the veterinarian about all medicines, supplements, and preventives. Parasite control is broader than deworming alone; for flea‑associated tapeworm risk, consider year‑round ectoparasite control such as Revolution For Dog or a veterinarian‑recommended alternative for cats or mixed households.

Good hygiene helps limit reinfection. Promptly pick up feces, wash bedding on hot cycles, and reduce access to intermediate hosts such as rodents or raw meats.

What to Expect Over Time

Stool quality and visible signs of intestinal parasites typically improve after a complete course and environmental cleaning. Some pets may require repeat courses or follow‑up fecal testing to confirm clearance, particularly with whipworms or Giardia. Ongoing preventive strategies, including routine fecal checks and parasite control products, are often advised in at‑risk areas. Results vary with parasite type, burden, and environment.

Compare With Alternatives

Several deworming options may be suitable alternatives based on species, parasites, and preference:

• Drontal Plus combines praziquantel, pyrantel, and febantel for broad intestinal coverage, including Dipylidium tapeworms.
• Profender is a topical dewormer for cats that covers roundworms, hookworms, and tapeworms.
• For pets that prefer non-liquid forms, Panacur Granules may be an option.

Selection should align with a veterinarian’s diagnosis and local parasite risks.

Patient Suitability and Cost‑Saving Tips

Panacur® Suspension is suitable for many dogs and cats with susceptible intestinal parasites. Suitability depends on species labeling, weight, age, health status, and parasite type.

• Ask a veterinarian about fecal testing and the right course length for the target parasite.
• Consider multi‑pet treatment plans when exposure is shared.
• Larger bottles may reduce per‑mL cost if repeat courses are expected.
• Set refill reminders for pets with recurring exposure risks.
• Combine deworming with year‑round preventives and hygiene for better long‑term control.

Questions to Ask Your Clinician

• Which parasites are suspected or confirmed on fecal testing?
• What dose and course length are recommended for this pet and parasite?
• Should all pets in the household be treated?
• Is a follow‑up fecal test needed, and when?
• What environmental or flea control steps should be added?
• Are there alternatives like Panacur Paste or Profender that might be easier to give?
• When should treatment be repeated to address the parasite lifecycle?
