Is Diflucan Safe to Take During Pregnancy?

Diflucan (fluconazole) is generally considered safe for single-dose treatment during pregnancy, but higher doses may pose risks. The FDA classifies fluconazole as Category C, meaning animal studies showed adverse effects but human data is limited. Studies show that single doses of 150mg for vaginal yeast infections appear safe during pregnancy. However, prolonged use or high doses (400-800mg daily) have been linked to birth defects in some studies. Most obstetricians prescribe topical antifungals as first-line treatment during pregnancy, reserving oral Diflucan for severe or resistant infections. Always consult your healthcare provider before taking any medication during pregnancy, as they can evaluate your specific situation and recommend the safest treatment option.
