Does Panacur C Have Side Effects?

Treating parasites in your pet can be a large burden that requires extensive treatment. Some parasites are easier to treat than others, as many external parasites (See Top 10 External Parasites) can be eliminated and even prevented with topical solutions; internal parasites, however, are a different matter. There are a wide variety of parasitic worms that can infest your pet and seriously threaten their health.

Among these parasitic worms exists several species that each affect your pet in a different way. Four of the most dangerous internal parasites that can infest your dog include:

  • Hookworms
  • Roundworms
  • Tapeworms
  • Whipworms
While whipworms generally reside in the colon of dogs, the other three worms all tend to inhabit the intestines. Each worm, however, can cause serious gastrointestinal distress in your dog that can result in diarrhea, vomiting, and weight loss.

Fenbendazole: The Active Ingredient

One of the best ways to treat these worms in dogs is with Panacur C, a dewormer that uses the active ingredient fenbendazole to attack roundworms, hookworms, tapeworms, and whipworms. It has been proven to be effective in dogs when used as directed; however, many potential buyers are wary of medications with known side effects. We'll address these concerns with an explanation of the side effects associated with the use of Panacur C and how to best prevent these adverse reactions.

What Are the Side Effects?

Panacur C has been associated with several side effects as determined by US clinical studies. The studies found that roughly 1% of the dogs treated with Panacur C experienced vomiting related to the product's use. For some context, it should be noted that a symptom caused by each of these parasitic worms include vomiting.

If your dog is sick and in need of deworming, consult your veterinarian for a diagnosis of the illness and to determine if Panacur C or another treatment works properly with the condition. If the dog being treated is in healthy condition and fits the indications, Panacur C should have no adverse effects on your pet aside from the aforementioned rare cases of occasional vomiting.

Follow the Directions

Other adverse reactions relate to ensuring that the product is used properly. Panacur C is intended only for puppies that are at least 6 weeks of age. Though it can be administered to pregnant dogs, it should not be given to a dog or puppy that is sick.

The following is the directions and a dosing table for Panacur C. It's recommended that you read the directions carefully and administer the proper dosage in order to minimize the chance of your dog experiencing side effects,
