Use in Pregnancy & Lactation
There are limited data on the use of Fluconazole in pregnant woman. However Fluconazole should be used in pregnancy only when the benefit clearly outweighs the risk.
Fluconazole is excreted in breast milk in levels about half of those found in plasma; therefore the drug should be avoided during lactation.
