From the Research

If you've experienced vaginal pain after applying menthol to your vagina, stop using it immediately and rinse the area with warm water. Menthol should never be placed in the vagina as it can cause significant irritation, burning, inflammation, and pain due to its cooling and irritant properties, as explained in the study on the role and mechanism of action of menthol in topical analgesic products 1. To relieve discomfort, take an over-the-counter pain reliever like ibuprofen (400mg every 6-8 hours) or acetaminophen (500mg every 6 hours), and apply a cold compress to the external genital area for 10-15 minutes to reduce inflammation. Some key points to consider when managing vaginal pain include:

  • Wear loose cotton underwear and avoid tight clothing until symptoms resolve
  • Avoid using vaginal douching or certain cleansers that can disrupt the vulvar and vaginal microbiota, as highlighted in the study on maintaining vulvar, vaginal, and perineal health 2
  • If pain persists beyond 24-48 hours, worsens, or if you develop unusual discharge, fever, or severe symptoms, seek medical attention promptly The vaginal tissue is delicate and sensitive with a carefully balanced pH and microbiome; introducing foreign substances like menthol disrupts this balance and can damage the protective mucous membranes, potentially leading to infections or chemical burns. It is essential to prioritize the health and well-being of the vaginal tissue by avoiding harmful substances and practicing routines, such as routine washing of the vulva with a pH-balanced, mild cleanser, as recommended in the study on maintaining vulvar, vaginal, and perineal health 2.
