What should I tell my health care provider before using fluconazole?

Before using fluconazole, tell your health care provider:

  • If you are allergic to fluconazole or any other medicines.
  • About any medical conditions you have or have had, including:
    • Kidney or liver problems
    • Heart problems
    • Electrolyte imbalances
    • Cancer
    • Genetic disorders that affect your body’s ability to absorb or breakdown sugars, including hereditary fructose intolerance, glucose/galactose malabsorption, or sucrase-isomaltase deficiency.
  • About anything that could affect your ability to take medicines, such as difficulty swallowing tablets, difficulty remembering to take tablets, or any health conditions that may prevent your use of intravenous medicines.
  • If you are pregnant or plan to become pregnant. Fluconazole should be avoided during pregnancy, except in situations where the potential benefit outweighs the potential risk to the fetus. Talk to your health care provider about the risks and benefits of using fluconazole during pregnancy. The Guidelines for the Prevention and Treatment of Opportunistic Infections in Adults and Adolescents with HIV may include other recommendations on the use of fluconazole during pregnancy. Please refer to these guidelines for additional information.
  • If you are breastfeeding or plan to breastfeed. For women with HIV in the United States, the Guideline does not recommend breastfeeding. Before your baby is born, or if you are already breastfeeding, talk to your health care provider to discuss alternative options for feeding your baby.
  • About other prescription and nonprescription medicines, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Fluconazole may affect the way other medicines or products work, and other medicines or products may affect how fluconazole works. Ask your health care provider if there are interactions between fluconazole and the other medicines you take.

Ask your health care provider about possible side effects from fluconazole. Your health care provider will tell you what to do if you have side effects.
