Ketoconazole
About Ketoconazole
Ketoconazole belongs to a class of drugs called antifungals indicated to treat various systemic fungal infections such as blastomycosis (infection caused by Blastomyces fungus), chromomycosis (chronic infection of the skin and subcutaneous tissue), Coccidioidomycosis (infection caused by Coccidioides fungus), paracoccidioidomycosis (infection caused by Paracoccidioides fungus) and histoplasmosis (lung infection caused by Histoplasma fungus). It is used only when other effective antifungal therapies are not available or tolerated and if potential benefits outweigh potential risks.
Ketoconazole contains Ketoconazole which works by destroying fungal cell membranes that are essential for their survival as they prevent the entry of unwanted substances into the cells and stop the leakage of cell contents. Thus, kills fungi and treats the fungal infection.
Take Ketoconazole as prescribed. Your doctor will advise you on how often you need to take Ketoconazole based on your medical condition. Some people may experience headache, nausea, stomach pain, and diarrhoea. Most of these side effects of Ketoconazole do not require medical attention and gradually resolve over time. However, if the side effects persist or worsen, please consult your doctor.
If you are allergic to Ketoconazole or any other medicines, please tell your doctor. If you are pregnant or planning for pregnancy, inform your doctor before taking Ketoconazole. Avoid breastfeeding while taking Ketoconazole as it may be excreted in breast milk. You are recommended to avoid alcohol consumption whilst on treatment with Ketoconazole. Ketoconazole is not recommended for children below 2 years of age. For children above 2 years, it is recommended to use only if the doctor has determined that the benefits outweigh the risks.

Patients Concern
Disease/Condition Glossary
Systemic fungal infections are fungal infections that affect internal organs. The fungus lives in the environment, particularly in moist soil and in decomposing organic matter such as leaves and wood. Fungi enter the body via the paranasal sinuses, gut, lungs, or skin, and may spread to other organs. If these infections are not treated with appropriate therapy or if treatment is delayed, it may lead to medical emergencies. The symptoms of systemic fungal infection in people with normal immune function include cough, fever, or loss of appetite. It can also affect people who are immune compromised.
