Anti Fungal for a Dog

Antifungal medications are used to treat skin and systemic infections in dogs. Medication works to weaken the fungus and stop its progression. Infections include common things such as ringworm and candida to more serious infections that invade the lungs, lymph system, deep skin tissues and heart. Fungal spores are inhaled from the environment, taking hold in the body and causing infection. If left untreated, infections will quickly spread, causing serious damage such as hair loss, organ failure or death.

  1. Ketoconazole

    • Veterinarians use ketocanzole for deep tissue infections such as blastomycosis, histoplasmosis, crytococcosis and some yeast infections. This medication is inexpensive, comes in tablet form and is often administered with vitamin C for better absorption. Side effects of the medication include such things as loss of appetite, vomiting, diarrhea, bleeding problems, jaundice and liver toxicity.

    Itraconazole

    • Itraconazole is prescribed for deep tissue infections and comes in capsule form. It is similar to keticonazole but is more expensive and better tolerated. It has fewer side effects but can cause stomach and intestinal upset.

    Griseofulvin

    • Griseogulvin is commonly used for ringworm. It is prescribed in conjunction with removing it from the environment such as pet bedding, because it is easily transmitted to humans. This medication can cause birth defects; it should not be used in pregnant dogs. Side effects of griseofulvin include such things as loss of appetite, vomiting, diarrhea, depression and weakness.

    Amphotericin B

    • Amphotericin B has been around for a long time and is used for sick dogs with life-threatening infections such as coccidioidomycosis. It is administered intravenously or by injection weekly. This medication requires close supervision by a veterinarian due to its potential for kidney toxicity.

    Miconazole

    • Miconazole comes in a variety of topical forms such as ointment, shampoo and spray. It is used to treat ringworm and yeast dermatitis. Side effects are rare but can include skin irritations such as redness and rash.

    Fluconazole

    • Fluconazole is becoming more popular and is used for deep fungal infections. It has excellent absorption rates, few possible side effects and is easier on the liver. This medication is cleared through the kidney, which requires monitoring. Side effects include excessive drinking and urination, and a thin and drying coat, which will reverse itself when medication is stopped.
