What You Need to Know About Using Boric Acid

Most of the research studies on using boric acid for prevention or treatment of vaginal infections have been done on the compounded preparations.

The products sold over the counter, while more accessible and more affordable, don’t make specific claims of their effectiveness. Most gynecologists assume these products would be effective, but see your provider if they are not.

Vaginal suppositories of boric acid are usually in 600 mg dosages.

Most use is considered ‘off label’ so we base success on resolution of symptoms.

For vaginal pH balance daily use for 7 days is recommended, for a vaginal yeast infection, usually 14 days, and in combination with BV treatment, up to 3-4 weeks of therapy will be necessary.

If you are using other vaginal medications there may be a variation in effectiveness.

If the medication stings, you need to be evaluated by a physician.

There are no real studies with tampon use, but most women hold off on vaginal dosing if using a tampon.

Consult your physician if you are pregnant before using during pregnancy.

Vaginal therapies such as MonaLisa and ThermiVA can help normalize pH without use of medication, or can be used in conjunction with other therapies.
