Acarexx ®

(0.01% ivermectin)

Acarexx® (0.01% ivermectin) Otic Suspension is a specially formulated ivermectrin treatment for ear mites in cats. ACAREXX is indicated for the treatment of adult ear mite (Otodectes cynotis) infestations in cats and kittens four weeks of age or older. Effectiveness against eggs and immature stages has not been proven.

ACAREXX is proven effective

  • Utilizes Wisdom™ technology, a water-based delivery system that allows ivermectin to be used safely in the ear
  • Penetrates exudate build-up to reach and kill mites

ACAREXX is proven safe

  • In safety studies, four-week-old kittens were administered Acarexx at dose rates of 1X, 3X and 5X the recommended dose for three or six consecutive days and no adverse reactions were observed, except one kitten treated at 1X the dose had histologic evidence of minimal, chronic dermal inflammation of the ear.
  • In approximately 1% of 80 cats and kittens, pain associated with the pinna and vomiting were observed following treatment with Acarexx.

A one-step ear mite treatment

  • Ear cleaning not necessary for efficacy


IMPORTANT SAFETY INFORMATION: The safe use of ACAREXX in cats used for breeding purposes, during pregnancy, or in lactating queens, has not been evaluated. ACAREXX suspension is a safe, convenient, proven ear mite treatment. In a well-controlled clinical field trial, ACAREXX was used safely in cats and kittens receiving other frequently used veterinary products such as flea control products, vaccines, anthelmintics, antibiotics and steroids. Not for human use.

CAUTION: Federal law restricts this drug to use by or on the order of a licensed veterinarian

The Ear Mite Problem

The Ear Mite Cycle

Ear mites are a common problem in cats, especially in kittens. These mites, Otodectes cynotis, typically live within the ear canal, but can also be found on other areas of the body or in the environment. Ear mites cause intense irritation as they move about the ear canal feeding on epidermal debris and tissue fluid. Ear mites complete their life cycle from egg to adult in five stages. The complete metamorphosis takes approximately three weeks as illustrated.

Phase 1: The Eggs

The female ear mite typically lays about five eggs per day for the entirety of her adult life. Deposited on the ear canal, the eggs hatch within four days.

Phase 2: The Larvae

Once hatched, larvae feed for 3-5 days before becoming lethargic for 24 hours as they molt into the nymph phase.

Phase 3: The Nymphs

There are two stages of nymphs: the protonymph and the deutonymph. Each feeds for 3-5 days, rests, then molts to the next stage.

Phase 4: The Adults

Barely visible to the naked eye, the adult ear mite appears white in color and feeds off the epithelial debris in a cat's ear. The record number of ear mites found in a cat's ear was 3,500.

Diagnosis

Clinical signs of ear mites in cats:

  • Head shaking
  • Scratching the ears (there may be sores around the ears as a result of scratching)
  • Reddish-brown to black discharge (crusts and cerumen) in the ears that resemble coffee grounds
  • No clinical signs*

A diagnosis of ear mites by the veterinarian is usually made by one of the following methods:

  • Direct visualization of the mites with an otoscope
  • Microscopic examination of the ear discharge

*Although some cats show no outward signs of ear mite infestations, the mites can be diagnosed as described above. Veterinarians often check for ear mites as part of the routine physical exam, especially in multi-cat households.

Nongreasy Acarexx® Suspension

Acarexx® suspension is nongreasy and easy to administer. Because it contains no irritating solvents, it won't cause hypersensitivity that can be associated with other products.

Traditional Treatments

Most other treatments are oil-based, which makes them difficult and messy to administer. Many contain solvents that can cause irritation and hypersensitivity in some cats.

The safe use of ACAREXX in cats used for breeding purposes, during pregnancy, or in lactating queens, has not been evaluated. ACAREXX suspension is a safe, convenient, proven ear mite treatment. In a well-controlled clinical field trial, ACAREXX was used safely in cats and kittens receiving other frequently used veterinary products such as flea control products, vaccines, anthelmintics, antibiotics and steroids. Not for human use.

CAUTION: Federal law restricts this drug to use by or on the order of a licensed veterinarian

Acarexx is administered topically in the ear canal at an ivermectin concentration of 0.01%. One dose of 0.5 mL is applied in each ear. Repeat treatment one time if necessary, based upon the ear mite life cycle and the response to treatment.

Acarexx is packaged in two polypropylene ampules per foil pouch, which are packaged 12 foil pouches per display carton. Each ampule is filled to deliver 0.5 mL of 0.01% ivermectin otic suspension per ear.
