Can panty liners cause thrush? It's a question that many women have asked themselves at some point. Panty liners are commonly used for daily vaginal discharge, light spotting, or as an extra layer of protection during your period. In this blog, we'll answer the question: can panty liners cause thrush? And explain what can cause a dreaded yeast infection and how to avoid them all together...

Can panty liners cause thrush?

What is thrush?

Yeast infections, also known as vaginal thrush, is a common type of infection that affects many women. It's caused by an overgrowth of the fungus Candida. Candida is naturally present in the vagina, along with other bacteria, but an imbalance in the vaginal flora can lead to an overgrowth of yeast, resulting in an infection. Yeast infections can cause symptoms such as:

  • Itching
  • Burning
  • Redness
  • Abnormal vaginal discharge

It's important to note that yeast infections are not considered sexually transmitted infections, although they can be transmitted through sexual contact. Factors that can contribute to the development of yeast infections include: 

  • Hormonal changes
  • Weakened immune system
  • Antibiotic use
  • Diabetes
  • Pregnancy
  • Taking oral contraceptives

While panty liners are not a direct cause of yeast infections, they can potentially exacerbate the condition if they are made from materials that irritate the vaginal area or disrupt the natural pH balance.

What causes thrush?

Yeast infections can have various causes, and it's important to understand them to prevent their occurrence. Some common causes of yeast infections include:

  • Imbalance in vaginal flora: The vagina contains a delicate balance of bacteria and yeast. When this balance is disrupted, it can lead to an overgrowth of yeast and the development of an infection. Factors that can disrupt the vaginal flora include the use of certain medications (such as antibiotics), hormonal changes, and douching.
  • Weakened immune system: A weakened immune system can make it easier for yeast to grow and cause an infection. Conditions that can weaken the immune system include HIV/AIDS, diabetes, and certain autoimmune disorders.
  • Hormonal changes: Hormonal changes, such as those that occur during pregnancy, can increase the risk of yeast infections. Hormonal fluctuations can alter the vaginal environment, making it more conducive to yeast growth.
  • Poor hygiene: Poor hygiene practices, such as wearing damp or sweaty clothing for extended periods, can create an environment that promotes yeast growth. It's important to maintain good hygiene habits, including regularly changing underwear and keeping the vaginal area clean and dry.

By addressing these common causes, you can reduce your risk of developing yeast infections and maintain a healthy vaginal environment.

The connection between panty liners and thrush

While panty liners themselves do not directly cause yeast infections, certain factors associated with their use can contribute to the development of an infection. The primary concern is the materials and ingredients used in the production of panty liners.


Many panty liners contain chemicals, fragrances, and dyes that can potentially irritate the sensitive vaginal area. This irritation can disrupt the natural pH balance of the vagina, creating an environment that is more conducive to yeast overgrowth.


Not all panty liners are created equal. Our panty liners are hypoallergenic materials and free from plastic, irritants and toxins. 

How to use panty liners

While panty liners can be a useful tool for managing daily vaginal discharge and light spotting, it's important to use them safely to minimise the risk of thrush. Here are some tips to consider:


  • Choose our panty liners: Opt for panty liners that are made from breathable, hypoallergenic materials and free from plastic and irritants.
  • Change them regularly: It's essential to change panty liners frequently to maintain cleanliness and prevent the buildup of moisture and bacteria. Ideally, panty liners should be changed every 4 to 8 hours or as needed.
  • Practice good hygiene: In addition to using panty liners, it's crucial to maintain good hygiene habits. This includes regularly washing the vaginal area with mild, unscented soap and water, and avoiding the use of harsh cleansers or douches.
  • Avoid excessive use: While panty liners can provide added protection, it's important not to rely on them excessively. Giving the vaginal area time to breathe without any liners can help maintain a healthy balance of bacteria and yeast.

Alternatives to panty liners

If panty liners aren't for you, that's fine! Here's some alternatives to consider include:

  • Reusable period pants: Period panties are specially designed to absorb menstrual flow without the need for additional liners or pads. 
  • Menstrual cups: Menstrual cups are a reusable and eco-friendly alternative to traditional sanitary pads and tampons. They collect menstrual blood without interfering with the vaginal flora.
  • Organic cotton pads: If using pads, choosing our 100% organic cotton pads can help minimise exposure to potential irritants and chemicals.
