Chronic Yeast Infections and Boric Acid

Recent research has confirmed prior work that suggests the use of boric acid is an effective treatment for vaginal yeast irritation. Chronic yeast irritation, commonly caused by Candida albicans, is a troubling condition that can cause symptoms of vulvar itching and burning, abnormal discharge, painful urination or intercourse, and vulvar swelling. Triggers for yeast imbalance include antibiotics use, pregnancy, changes in glucose metabolism, and use of certain oral birth control pills. Tight clothing and use of plastic pantiliners can also create an environment in which yeast growth can cause symptoms.

The availability of over-the-counter yeast treatment has led to patients misdiagnosing and often over-treating with such medications. The ingredients in many of the available creams or suppositories can cause allergic reactions, vaginal burning, irritation, or itching. Many of our patients who complain of pelvic pain may be dealing with a history of or a current case of low grade (non-acute), recurrent yeast overgrowth and subsequent tissue irritation that can create a chronic pain condition. There are several intravaginal treatments that have been used by patients including boric acid tablets. Knowing that I worked with a high population of women's health patients, I recall my naturopath handing me an article over a decade ago that described the superior results of boric acid over nystatin. Some providers recommend the use of boric acid in the evening, followed by intravaginal probiotics in the morning. Boric acid can cause local skin irritation as a side effect, but no other significant side effects have been reported when used vaginally.

In a reviewby Iavazzo and colleagues about recurrent vulvovaginal candidiasis, the use of boric acid is presented. The studies included in the review reported a 40-100% cure rate with minimal side effects. The authors conclude that boric acid is an economic, safe option for women who have non-albicans Candida strains of yeast overgrowth or for those who have azole-resistant strains. The National Institutes of Health recommends avoiding vaginal douching or feminine hygiene sprays, rinsing with water only (no soap), use of condoms to prevent spread of sexually transmitted infections, wearing cotton underwear and avoiding tight, non-breathing clothing, and keeping blood sugars in check.

We can keep this information in mind when working with patients who complain of pelvic pain, vaginal or vulvar burning. Of course, these symptoms can also be attributed to neuromuscular pain, referred symptoms, or a chronic pain cycle. The above information about boric acid can be presented to the patient if she reports a history of chronic yeast irritation and she can then discuss the option with her medical provider. According to Donders, patients often feel misunderstood, guilty, and feel sexually inferior due to chronic candidosis, requiring that medical providers consider this issue as one to be taken seriously. Having the information about options such as boric acid appear in medical journals helps to highlight the importance of managing this condition that is often recurrent and sometimes difficult to treat.
