Boric acid suppositories contain the naturally occurring compound boric acid and are designed for vaginal insertion. They are primarily used to help restore and maintain the vagina’s natural acidic pH balance. Boric acid possesses mild antifungal and antibacterial properties, making the product useful as an alternative or complementary treatment for conditions such as recurrent yeast infections and bacterial vaginosis (BV). The suppository is typically a capsule containing a measured dose of boric acid powder that dissolves after insertion.
Is Burning a Normal Side Effect?
A sensation of mild burning, stinging, or warmth is a common and temporary side effect when using boric acid suppositories. This discomfort results from the weak acid compound interacting with the sensitive vaginal mucous membrane. The vaginal tissue is often already irritated due to the underlying infection or pH imbalance being treated, making it more reactive to the substance.
The intensity of this sensation depends on the health of the vaginal lining at the time of insertion. If there are micro-abrasions, open sores, or significant dryness, the irritation will be more pronounced. This mild discomfort should subside shortly after the suppository fully dissolves and the active ingredient begins to disperse.
Other mild side effects reported alongside burning include watery vaginal discharge or leakage. This discharge occurs as the suppository dissolves and the body expels the liquid and residue. Users may also notice a slightly gritty sensation in the vagina as the powder dissolves.
How to Minimize Irritation During Use
To help reduce the risk of irritation, insert the suppository as deeply into the vagina as is comfortable. Proper deep placement ensures the suppository dissolves in a moisture-rich area, minimizing contact with sensitive tissue near the vaginal opening. Using a suppository applicator, if one is available, can assist with correct and gentle placement.
Timing the insertion can enhance comfort during treatment. Inserting the suppository right before bed allows the product to dissolve and work while the user is lying down. This reduces movement, minimizes leakage, and helps prevent the dissolved product from running down toward the sensitive vulvar skin.
Wearing a panty liner is highly recommended to manage the inevitable discharge. This protects clothing and prevents the boric acid discharge from causing external skin irritation. It is also advised to avoid sexual intercourse and the use of tampons while undergoing treatment.
Warning Signs: When to Stop and Consult a Doctor
While mild, temporary irritation is common, any instance of severe or unbearable pain is a clear indication to discontinue use immediately. The burning should not be debilitating or worsen significantly over time; if it does, it suggests a more severe reaction or underlying issue. Users should also stop using the product if they notice signs of an allergic reaction, such as hives, significant swelling of the lips or throat, or difficulty breathing.
Other warning signs that require immediate medical consultation include the development of a high fever, chills, or nausea, which may suggest a systemic infection or complication. Abnormal vaginal bleeding not related to menstruation, new pelvic or lower stomach pain, or symptoms that persist or return immediately after the course of treatment is finished are also important indicators. Boric acid should not be used if there are open sores, wounds, or ulcerations in the vaginal area, as this can increase irritation and the potential for toxicity.
