Panacur® C should be administered as directed by your veterinarian. Efficacy is dependent on the correct dose level based on body weight over the appropriate treatment period. When possible, animals should be weighed to determine body weight accurately. 
Packet size is the daily dose, the pet must be treated with this dose for 3 consecutive days or as directed by your veterinarian.  Mix powder in a small amount of food and make sure your pet eats all of the medicated food.

Missed Doses
Give the dose as soon as possible. If it is almost time for the next dose, skip the missed dose, and continue with the regular schedule. Do not give 2 doses at once.
Side Effects
Side effects may include possible vomiting. Fenbendazole may cause hypersensitivity reaction upon the death of the parasite releasing antigens.
Other side effects may occur. If you notice anything unusual, contact your veterinarian.
Drug & Food Interactions
The following drugs can potentially interact with fenbendazole: dibromsalan and tribromsalan. Contact your veterinarian if your canine experiences any unusual reactions when different medications are given together. 
Make sure to tell your veterinarian what other medication you are giving to your canine. Quite often your veterinarian may prescribe two different medications, and a drug interaction may be anticipated. In this case, your veterinarian may vary the dose and/or monitor your canine more closely. 
Panacur® C is for use in dogs only. Do not administer to cats or a sick dog/puppy. This medication should not be used in animals allergic to fenbendazole.
