Ketoconazole is an antifungal agent. It works by interfering with the production of the main building block of the fungal cell membrane. This allows the contents of the cell to leak out, resulting in fungal cell death.


Along with its needed effects, ketoconazole may cause some unwanted or undesirable effects. The severity and duration of these effects are dependant on many factors including duration of therapy, dose, and individual response. Possible unwanted effects include:

  • nausea
  • vomiting
  • stomach pain

Uncommon:

  • diarrhea
  • headache
  • dizziness
  • drowsiness
  • itching
  • skin reactions
  • liver problems

Ketoconazole should be taken exactly as prescribed. Continue taking the medication until it is finished or it will prevent complete elimination of the fungi (e.g. yeast), causing the infection to return.
Ketoconazole has caused liver disease in some patients. Notify your doctor if you experience any of the following signs or symptoms: unusual fatigue, appetite loss, nausea, vomiting, yellowing of the skin or eyes (jaundice), dark urine or pale stools. Depending on the length of ketoconazole therapy, lab tests may be required to monitor how well your body is handling the ketoconazole. These tests will include liver function tests.
Treatment with ketoconazole can last as little as 1 week when treating thrush or in excess of 6 months when treating certain internal infections.

Antacids interfere with the dissolving of ketoconazole in the stomach, making it far less effective. Therefore, antacids should not be taken within 2 hours of the ketoconazole dose.
