During pregnancy, it is recommended to avoid taking high doses of Fluconazole (Diflucan) due to the risk of congenital malformations. Instead, topical azoles like Canesten (clotrimazole) or Monistat (miconazole) are the preferred treatments for yeast infections. For a yeast infection during pregnancy, you can consider using Canesten® Combi-Pak, which includes vaginal ovules and an external cream. Follow the recommended dosage instructions and if your symptoms persist after 5 days, it's advisable to consult a doctor as it may not be a yeast infection. It is important to address any vaginal infections promptly during pregnancy.
