At Pinc Wellness, our story began with a simple but life-changing discovery: boric acid suppositories. After years of frustration, countless doctor’s appointments, and recurring cycles of antibiotics that never really worked, we knew there had to be a better way to care for our vaginal health.

So many women come to us feeling frustrated with the limited medical solutions for thrush and BV, hoping for natural alternatives. We've been there, and we want you to know, you're not alone.

When we found a solution that was gentle, effective, and actually worked, everything changed. 

This is why Pinc Wellness was born: to bring these solutions to more women who have faced challenges when it comes to vaginal health. We’re here to help you love your vagina, and live your life in full, feminine flow.

One common question we’ve been asked lately is:

Can you use boric acid suppositories on your period?

Let’s break it down.

First, What Is Boric Acid and Why Use It?

Boric acid is a natural compound with antiviral, antifungal, and antiseptic properties. It’s been used for generations to support vaginal health, particularly for:

  • Recurrent yeast infections
  • Bacterial vaginosis (BV)
  • Persistent discharge or odour
  • pH imbalance

By restoring the vagina’s acidic environment, boric acid helps maintain a healthy microbiome and reduces the risk of overgrowth from harmful bacteria or yeast.

So… Can You Use Boric Acid on Your Period?

Yes ~ boric acid suppositories can be used during your period. But there are a few things to keep in mind.

Period Blood Affects Vaginal pH Levels

During your period, the presence of blood temporarily raises your vaginal pH (making it more alkaline). This shift can make it easier for infections to begin, which is why some women notice symptoms may flare up during or after their cycle.

Boric acid can help rebalance this, making it a natural option even during menstruation.

However, Vaginal Health Effectiveness May Vary

  • Blood flow can reduce absorption. A heavier period may cause the suppository to be expelled before it fully dissolves.
  • Tampons may interfere. Tampons can absorb the boric acid and reduce its effectiveness.
  • You may prefer to wait. You can choose to pause use during your heaviest days and resume on your lighter days.

Best Practices if You Choose to Use Boric Acid on Your Period

If you do choose to use boric acid suppositories during your period:

  • Use them at night to maximise absorption while your body is at rest.
  • Opt for breathable protection like period underwear or liners instead of tampons.
  • Stay consistent if you’re following a course for a specific condition, but adjust based on your flow and comfort.

We love pairing boric acid use with our favourite Bamboo Period Underwear. They’re soft, sustainable, and leak-proof, a great option for gentle care during your cycle.

When to Avoid or Pause Use of Boric Acid 

You may want to avoid using boric acid during the heaviest days of your period or if it causes irritation. And as always:

⚠️ Boric acid should never be used during pregnancy
⚠️ Boric Acid is for vaginal use only, do not ingest it

If you’re unsure whether it’s the right time to use it, consult your healthcare provider for personalised advice.

So the answer to the question, ‘Can Boric Acid be Used on Your Period?’ is ‘yes’, boric acid suppositories can be used, and can offer much-needed relief during a time when symptoms of thrush and BV may worsen.
