Common Cat Wormer Side Effects

Cat wormer medication is available for cats in all age ranges. Kittens can also contract worms from the queen (mother) before birth and should be treated. There are many commercial cat worm medicines that both treat and prevent re-infection. However, some medicines may not be suitable for all cats, and can cause side effects. Before administering any medication it's useful to read labels, follow instructions and consult your vet if you're in doubt. Cats suffering from other illnesses shouldn't be given medication without prior vet consent.

Commercial Cat Worming Medication:

  • Droncit for cats over 6 weeks of age
  • Tape Worm Tabs Cat
  • Cestex for cats over 7 weeks of age
  • Revolution
  • HomeoPet Worm Clear
  • Drontal

Worms mature and survive in your cat's digestive system. They eventually destroy the cat's immune system. Cat worm medication is used to treat hookworms, roundworms and tapeworm infections. Some drugs contain praziquantel, pyrantel pamote, febantel and selamectin. The active ingredients destroy the intestinal worms by damaging their skin internally. Your cat will then pass the worms in the stool.

Side Effects:

  • Diarrhea
  • Vomiting
  • Loss of appetite
  • Drowsiness
  • Salivation
  • Loss of hair in case of topical injections

Cat worming medication cannot be used on cats suffering from ailments or from weakness. Side effects are temporary, but if your pet shows prolonged symptoms, it's best to seek medical attention. Cats suffering from kidney problems are more likely to have harsh side effects. Some worm medication shouldn't be used on pregnant cats.

Before purchasing over the counter medication for worm treatment, consider taking your pet for a vet check. The fecal examination will determine the type of worm infection in your cat. Although some drugs treat two or more worms with the same dosage, cats in general should be specifically treated for those worms they are infected with. It's important to keep your vet informed if your pet has an allergic reaction to worm medicines.

One common source of cat worms is fleas and ticks. Certain flea medications contain active ingredients that also cause side effects.

How Often Should You De-Worm Your Pet?

Kittens should receive their first dose of de-worming medication at six weeks of age. The medication may be repeated at ten weeks of age. Adult cats should be treated regularly for worms as per instructions on the package. If you have recently brought a new pet home, it's essential to treat him for worms, as well as fleas and ticks.

Along with worm medication it's necessary to take measures to prevent your cat from contracting worm infections. There are also commercial holistic treatments for preventing cat worms. Remember to schedule your cat for routine vet checks and conduct fecal exams at least twice a year.
