Sporanox (Itraconazole) for Cats

Itraconazole, also known as Sporanox, is an anti fungal medication that will interfere with the development of fungi. The formula of itraconazole is similar to ketaconazole or miconazole, and is effective in stopping fungal infections caused by yeast organisms, as well as blastomycosis and cryptococcosis.

Uses of Itraconazole

Itraconazole can be used in cats that are affected by fungal infections. Itraconazole is only effective for fungal infections that are caused by yeast cells, blastomycosis and cryptococcosis. The yeast cells exist normally on the skin of the cat, but these cells may overgrow and an infection can occur. The yeast cells may also cause ringworm infections and paw infections. Blastomycosis and cryptococcosis can affect the skin, bones, lungs or the brain. Itraconazole may be administered topically or orally.

Itraconazole Dosage

Itraconazole is only available through prescription. Itraconazole is formulated for humans but may be safely used in felines as well. The vet should establish if the use of itraconazole in your pet is recommended. The dose will be established judging by the severity of the fungal infection as well as the age, size and sex of the cat. The medication should be administered as prescribed by the vet; typically, cats will receive itraconazole 2 times per day for 2 to 3 weeks. The topical ointments should also be used for a few weeks; you should continue using the creams even after the infection is gone, to ensure that all the fungi are gone and to prevent a possible relapse.

Itraconazole Side Effects

Itraconazole can be used in felines without major risks; however, a few side effects may occur in more sensitive cats. Some cats may develop allergies to itraconazole. In rare cases, the lengthy administration of the drug may affect the liver, causing hepatitis. Watch out for symptoms such as:

  • jaundice (yellow eye whites and other mucous membranes)
  • lack of appetite
  • weight loss
  • vomiting
  • diarrhea

All these may point to a liver dysfunction.

Itraconazole may also delay the effect of other medications or interact with them. Talk to your vet and inform him if your cat is under medication. Anatcids, cisapride or a few types of antibiotics may interact with the effects of itraconazole.

However, Itraconazole has been reported to have fewer side effects than other similar anti fungal medication such as ketonozole or miconazole. Other less common side effects may include vomiting, diarrhea, lack of appetite and lack of energy.

Contraindications

Itraconazole shouldn’t be administered to felines that are allergic to this medication. The medication should also be used with caution in pregnant and lactating cats.

Similar Drugs

Drugs that may have the same effects as itraconazole in pets include ketanozole, miconazole or fluconazole. These medications may also be used in felines, but the vet must prescribe them first. However, itraconazole has been proven to be more effective and has fewer health risks than the other anti fungal formulas.
