Boric acid dervives from boron, an element that's typically found in minerals. The substance has been used for over 100 years to treat vaginal infections like yeast infections and bacterial vaginosis due to its anti-microbial and anti-fungal properties. Boric acid suppositories can help replenish normal vaginal acidity and balance the vaginal flora. It can also relieve symptoms like burning, itching, and irritation.

For active infections: Insert 1 suppository at night into the vagina for 5-7 days or as per your health practitioner’s advice

For maintenance: Insert 1-2 suppositories per week, or as per your health practitioners advice

Consult a health professional before use

Boric acid suppositories are generally safe for adults, but they can cause minor side effects.

Gynecologists state that boric acid suppositories can cause spotting or bleeding in a small percentage of women. If the bleeding is slight or occurs alongside your normal menstrual flow, it is generally safe to continue using boric acid. However, always consult your medical professional if spotting occurs.

It's very important to insert the pessary as high up into the vagina as possible to prevent this. Also, boric acid requires moisture to dissolve. Some women experience vaginal dryness prior to a period. Peri menopause and menopausal women may also struggle with vaginal dryness. To combat this, some women prefer to insert the pessary with a water based lubricant to moisten the environment to allow the boric acid to fully dissolve.

Please talk to your health provider about choosing a suitable dose. 600mg is the standard dose. 300mg may be more suitable for those who are new to using boric acid suppositories, experience vaginal dryness or are menopausal.
