Liver Safe If Prescribed

Fluconazole should be used with caution in patients with liver dysfunction. There are rare cases of serious hepatotoxicity related to fluconazole occurring mainly in patients with serious underlying medical conditions. However, no obvious relationship to total daily dose, duration of usage, sex or age of patient have been reported. Fluconazole-associated hepatotoxicity is usually reversible following discontinuation of therapy. If patients develop an abnormal liver function test while on treatment, it is important to monitor such patients closely for more serious liver injury.
