What Panacur Is and How It Works
Panacur® Granules 22.2% is a canine dewormer containing fenbendazole. It removes roundworms, hookworms, whipworms, and certain tapeworms as labeled. This page explains dosing, packet options, and how ordering works with US delivery from Canada, including options if you pay without insurance.
CanadianInsulin.com is a prescription referral platform. We verify prescriptions with your prescriber when required, and licensed Canadian pharmacies dispense your order.
The active ingredient interferes with parasite energy metabolism, which helps clear susceptible gastrointestinal worms. These fenbendazole 22.2% granules for dogs are mixed with food. Always follow the package directions for the full course and confirm the targeted parasites with your veterinarian’s diagnosis.
Who It’s For
This treatment is intended for dogs as directed on the label. It may be used in adult dogs and eligible puppies when a prescriber confirms the indication. Cats should not receive this canine formulation. Do not use in animals with known hypersensitivity to benzimidazoles unless a veterinarian advises otherwise. If your dog is debilitated or has significant illness, discuss risks and timing before deworming. For pregnant or nursing dogs, review the label and seek veterinary guidance on appropriate use.
Routine fecal checks help determine need and timing. Deworming plans can vary by region, lifestyle, and exposure risk. Browse other options in our Pet Medications category for broader care planning with your clinic.
Dosage and Usage
Follow the labeled schedule based on your dog’s weight. Each daily dose is given once per day for three consecutive days unless your veterinarian specifies a different protocol consistent with the label. Mix the daily dose with a small portion of food. Ensure your dog consumes the entire meal to receive the full dose. Offer the rest of the meal afterward.
You may combine packet sizes to match the total daily dose for your dog’s weight. Keep the dosing consistent at roughly the same time each day. If multiple pets need treatment, dose each dog individually according to its weight. The labeled composition is fenbendazole granules 22.2% 222 mg/g.
Wash hands after handling packets and feces. Clean the dog’s environment to help reduce re-exposure. Consult the official label if you are unsure which packet sizes to combine for your dog’s weight range.
Strengths and Forms
The granules are supplied in boxes containing three daily-dose packets. Availability can vary by pack size.
| Packet Size | Typical Use | Notes |
|---|---|---|
| 1 g | Smaller dogs; combine as directed | Three packets per box |
| 2 g | Medium dogs; combine as directed | Three packets per box |
| 4 g | Larger dogs; combine as directed | Three packets per box |
Many pet owners look for Panacur Granules 22.2% 1 g packets when dosing small dogs, then combine sizes for higher weights as directed by the label. Pack options and imagery on this page reflect commonly available products; stock can change.
Missed Dose and Timing
If you miss a daily dose, give it when you remember the same day. If the next day is already due, resume the regular schedule and complete the three-day course as guided by the package directions. Do not double up doses at one time. Maintain a steady routine to support consistent parasite clearance and discuss any gaps with your veterinarian if you are unsure how to proceed.
Storage and Travel Basics
Store the packets at room temperature in a dry place. Keep them sealed until use and protect from moisture. Do not freeze. Keep out of reach of children and other animals. When traveling, carry packets in original packaging along with the product insert or a copy of your order details. If flying, keep them in your carry-on. Products are handled with temperature-controlled handling when required.
Benefits
This medicine treats labeled intestinal parasites in dogs. The granules mix easily with a small portion of food, which can simplify dosing. Pack sizes let you match your dog’s weight by combining packets under label guidance. Three-day schedules are straightforward, and most dogs accept the granules well when mixed with a palatable meal.
Side Effects and Safety
- Soft stool or diarrhea
- Vomiting or reduced appetite
- Lethargy for a short period
- Transient drooling after dosing
- Abdominal discomfort
- Rare hypersensitivity signs related to parasite die-off
Serious reactions are uncommon but can occur. Stop dosing and seek veterinary care if your dog shows signs of severe vomiting, persistent diarrhea, facial swelling, hives, trouble breathing, or collapse. Dogs with heavy parasite burdens may pass worms in stool after treatment. Monitor closely and maintain hydration. Use only as labeled for dogs and keep all medicines away from children.
Drug Interactions and Cautions
Tell your veterinarian about all medicines, supplements, or additional dewormers your dog uses. Concurrent use with other anthelmintics or treatments may need veterinary oversight. Discuss any history of drug reactions. If your dog has underlying liver, intestinal, or systemic disease, confirm the timing and need for deworming. Do not use outdated or damaged packets. Dispose of unused packets responsibly per local guidelines.
What to Expect Over Time
During the three-day course, most dogs tolerate dosing well. You may observe worms or segments in stool as parasites are cleared. Stool checks after treatment may be recommended to confirm response. Households with multiple pets often need coordinated care and environmental cleaning to reduce re-exposure. Your veterinary team may suggest periodic deworming based on lifestyle and regional risk.
Compare With Alternatives
Some dogs may require broader tapeworm coverage or different active ingredients. Your clinician might consider combination dewormers such as Drontal® Plus. For single-ingredient praziquantel, an option is Droncit®. For background on tapeworm management, see our article on Tapeworm Treatment. Your veterinarian can help match the product to the parasites identified.
Pricing and Access
See current pricing on the product page and compare pack sizes before checkout. We offer Canadian pricing with transparent costs. Orders ship from Canada to US for eligible addresses. If you plan to buy fenbendazole granules 22.2%, review your dog’s weight and choose the packet size or combination that matches the labeled dose. For occasional coupons, visit our Promotions page.
Availability and Substitutions
Supply can vary by packet size. If a particular size is unavailable, your prescriber may advise combining other packet sizes or choosing a different dewormer from the same class or a suitable alternative. We do not provide restock dates, but our catalog updates as inventory changes.
Patient Suitability and Cost-Saving Tips
Dogs that need labeled parasite coverage and can take granules with food may be good candidates. Confirm suitability if your dog is very small, elderly, pregnant, nursing, or has chronic illness. To manage costs, consider multi-box orders when advised, align refills with routine fecal checks, and store packets properly. When discussing options, ask about generic fenbendazole 22.2% granules and whether combining packet sizes can reduce waste. Use reminders to avoid missed days in the three-day course.

How do the granules work?
The active ingredient is fenbendazole, a benzimidazole anthelmintic. It interferes with energy processes in susceptible intestinal parasites, which helps clear them from the gastrointestinal tract. You mix the daily granules with a small portion of food so your dog eats the full dose. Most dogs tolerate the therapy well, but you should monitor stool and general behavior during and after treatment and report concerning changes to your veterinarian.
Which worms are covered?
The labeled spectrum includes common canine intestinal parasites such as roundworms, hookworms, whipworms, and certain tapeworms (for example, Taenia species). Your veterinarian should confirm the parasite type through testing and select the appropriate product and schedule. Because regional risks vary, stool checks and preventive strategies may be recommended to reduce re-exposure after treatment.
How should I give a dose?
Open the packet and mix the entire daily amount into a small portion of food. Make sure your dog eats the full portion, then offer the rest of the meal. Give the dose once daily for three consecutive days as the label directs, unless your veterinarian instructs a different label-aligned plan. Keep doses consistent each day and complete the course even if your dog seems improved.
Can puppies use it?
Use is label-directed for dogs, including eligible puppies when your veterinarian confirms the indication and weight-based dosing. Very young or underweight puppies should be assessed before treatment. Provide the correct daily dose each day, complete the full three-day course, and monitor for gastrointestinal upset such as vomiting or diarrhea. Seek veterinary guidance if your puppy has other illnesses or is taking additional medications.
What if my dog vomits after a dose?
If vomiting occurs soon after dosing, call your veterinarian to discuss whether to repeat the dose and how to proceed with the three-day course. Keep your dog hydrated and watch for persistent symptoms or any signs of distress. Do not double up doses without guidance. If vomiting or diarrhea continues, your clinician may adjust timing, meals, or recommend an alternative product.
Can I mix packets to match weight?
Yes. Packet sizes are designed to be combined to match the daily dose for your dog’s weight under the label. Your veterinarian or the product insert can help you select the correct combination. Mix the total daily amount into food and ensure complete consumption. Record which sizes were used each day to avoid errors and to keep the three-day schedule on track.
Do I need a follow-up deworming?
Follow-up depends on fecal test results, exposure risk, and your veterinarian’s plan. Many clinics recommend a post-treatment stool check to confirm clearance, then periodic screening. Environmental control and flea management reduce re-exposure risk for some parasites. Your prescriber will advise if and when to repeat treatment or switch to a different product based on local patterns and your dog’s lifestyle.
