Frequently Asked Questions
What is the correct fenbendazole dosage for dogs?
The standard fenbendazole dosage for dogs is 50 mg per kg (22.7 mg per lb) of body weight, given once daily for 3 consecutive days. This treats common parasites including roundworms, hookworms, whipworms, and some tapeworms. Always consult your veterinarian for the correct dosage for your specific dog.
How do I calculate fenbendazole dosage by weight?
To calculate fenbendazole dosage by weight: multiply your pet's weight in kilograms by 50mg. For example, a 10kg (22lb) dog needs 500mg of fenbendazole per day. If using Panacur granules (22.2%), you would give approximately 2.25 grams. Our calculator above does this math automatically.
What is the fenbendazole dosage for cats?
Cats require the same dosage as dogs: 50 mg per kg of body weight, once daily. However, treatment duration may be 3-5 days depending on the parasite being treated. Fenbendazole is generally safe for cats but should be prescribed by a veterinarian.
What is the Joe Tippens Protocol fenbendazole dosage?
The Joe Tippens Protocol uses a fixed dose of 222 mg of fenbendazole (1 gram of Panacur C granules) daily for 3 consecutive days, followed by 4 days off. This cycle repeats weekly. Note: This is not FDA-approved for human use. Always consult a healthcare provider before using any medication off-label.
How much Panacur should I give my dog?
Panacur (fenbendazole) dosage depends on the product concentration. For Panacur C granules (22.2%): give 1 packet per 10 lbs of body weight. For Panacur liquid suspension (10%): give 1 ml per 2.2 lbs (1 kg). Our calculator above converts your dogs weight to the correct Panacur amount.
Is fenbendazole safe for puppies and kittens?
Fenbendazole is generally considered safe for puppies over 6 weeks old and kittens. It has a wide safety margin. However, very young or small animals require precise dosing. Always weigh your pet accurately and consult your veterinarian, especially for first-time treatment.
What is the difference between Safe-Guard and Panacur?
Safe-Guard and Panacur both contain the same active ingredient: fenbendazole. Safe-Guard is marketed by Merck for livestock and some pet products, while Panacur (by Intervet/Merck) is more commonly used for dogs and cats. The dosing is identical for the same concentrations.
How long does fenbendazole take to work?
Fenbendazole begins working immediately after administration, but you may not see dead worms in stool for 1-3 days. A full 3-day treatment course is needed to kill all parasites and their larvae. For Giardia, a 5-day course is typically recommended.
Can I give fenbendazole with food?
Yes, fenbendazole should be given with food for best absorption. Mixing with a small amount of wet food or giving it with a fatty treat (like peanut butter) can increase effectiveness. This is true for both pets and the human protocol.
What parasites does fenbendazole treat?
Fenbendazole treats a wide range of parasites including: Roundworms (Toxocara, Toxascaris), Hookworms (Ancylostoma, Uncinaria), Whipworms (Trichuris), some Tapeworms (Taenia), Giardia, and Lungworms. It is not effective against all tapeworms or external parasites.
