Ivermectin to Cure Ear Mites in Cats

Ear mites are a fairly common issue in cats, but fortunately they are fairly easy to treat. Ivermectin is an anti-parasitic medication used to control both internal and external parasites in cats, including ear mites. Owners who suspect their cats may have ear mites should seek veterinary care, as there are several infections that can be similar in appearance to an ear mite infestation.

  1. Identification: Ear Mites

    • Ear mites in a cat are fairly easy for a well-trained veterinarian to recognize. The classic symptoms include shaking of the head and scratching at the ears, as well as a dark reddish brown or black discharge that is present in the ears. The discharge is often described as being similar in appearance to coffee grounds. Secondary infections that occur because of the ear mites can cause an unusual odor, so veterinary attention should be sought for a proper diagnosis and treatment.

    Dosage and Administration

    • In the paste form, ivermectin is available in either a 0.153 percent or a 1.87 percent strength. Liquid forms are also available in a 10 milligram per milliliter dosage. Exact dosage will vary based on the severity of the infection as well as the cat's weight. Minor cases may only require a single administration of the medication at the veterinarian's office and will not require any further administration by the owner. Severe cases may require additional treatments, which may or may not be done at home, and the overseeing veterinarian will give instructions as necessary.

    Side Effects

    • As with any medication, potential side effects may occur, but side effects usually only occur following an overdose of ivermectin. For example, cats may begin to stumble or suffer from tremors. They may become disoriented or weak. Some cats may suffer from blindness, which may be permanent or temporary. Cats who display these symptoms should be taken to a veterinarian immediately.

    Warning

    • Unfortunately, ear mites are extremely contagious parasites and can be transmitted to many different household pets including dogs, other cats, and even rabbits. If one pet becomes infested with ear mites, it is important that all pets within the home receive treatment. Treatment should be administered even if a pet is not showing any outward signs of an ear mite infestation. Otherwise, he could develop an infestation and spread the mites to other cats, even after the original cat has been treated for ear mites.

    Other Infections

    • Yeast infections can produce symptoms similar to those produced by an ear mite infestation, including shaking of the head, black discharge, redness, and inflammation. Therefore, it is important to have a veterinarian confirm the type of ear infection present rather than administering over-the-counter ear mite medications as these will only worsen a yeast infection.
