How long does it take boric acid to work used as a vaginal suppository, boric acid is an effective treatment for yeast infections that do not respond to other antifungal medications. It works by preventing the growth of Candida fungi, which can cause itching and other symptoms.
The CDC recommends using boric acid for acute yeast infections as a first-line treatment, then adding an oral antifungal medication such as fluconazole (Diflucan) as second-line therapy. When these medications do not work, the doctor may prescribe a more powerful antifungal, such as nystatin or flucytosine.
To safely use a boric acid suppository, follow the instructions on the label, which includes finding a private and calm place in your home to insert the suppository. After removing the suppository from the packaging, gently insert it into your vagina as far as feels comfortable. Once inserted, it is important to wash your hands thoroughly.
You may experience some discharge from the suppository, so you may want to wear a panty liner while using it. The capsule will dissolve in a few minutes, and the discharge should clear up shortly afterward.
As with any medicine, boric acid is not without risks, including gastrointestinal problems, such as damage to the esophagus and stomach. However, these side effects are rare and usually go away on their own once the dose of boric acid has been reduced or stopped. People who are pregnant or plan to become pregnant should not use boric acid, because it can be toxic to fetuses.
