Your provider can prescribe a more effective treatment to get rid of your infection. You might need to use other medications or a combination of medications.
Using boric acid vaginal suppositories may break down some blood thinners, such as warfarin (Coumadin), so you should talk with your provider before you take it if you are taking these medicines.
Don’t take boric acid if you are pregnant or breast-feeding, because it can increase your baby’s risk of birth defects. Excessive doses of intravaginal boric acid during pregnancy have been linked to fetal weight reduction and malformations in mice, rats, and rabbits.
