Research suggests that when used appropriately, boric acid suppositories can help reduce the risk of recurrent infections.
When the pH is disrupted, you may be more prone to vaginal infections and irritation.
That said, laboratory-based studies have shown that boric acid can effectively inhibit the growth of trichomonas.

Otherwise, there is a risk that you could pass an infection back and forth.
BV is not generally thought of as a sexually transmitted infection.

Typical treatment for a yeast infection involves inserting one suppository daily for 10 to 14 days.
Forrecurring yeast infections, daily use for 21 days may be called for.
How long you should use boric acid suppositories can vary and should always be discussed with your healthcare provider.
