Three reasons why menstrual blood leaks even when using a tampon
There are three reasons why menstrual blood leaks when using tampons:
- Using tampons for a long time
- The tampon is not in the right place
- The amount of menstrual blood is greater than the tampon can absorb
Please check to see if any of the items apply to you.
Using tampons for a long time
If you use a tampon for too long, it will exceed its absorption capacity and leak menstrual blood.
Generally, tampons should last for 4 to 8 hours.
However, on days when your menstrual flow is heavy, regardless of the time, if you do not change your sanitary pad early, there is a risk of menstrual leakage.
Although the link between tampons and toxic shock syndrome is unclear, it has been suggested that the absorbency of tampons may be a contributing factor. [1]
To prevent menstrual leakage and infection, be sure to limit the continuous use time.
The tampon is not in the right place
If the tampon is inserted in the wrong position, it will not absorb the menstrual blood properly and will be more likely to leak.
For example, if you're not used to using tampons, you may end up inserting them too shallowly out of fear of inserting them too deeply. The abdominal pressure can cause them to shift position, which can lead to leakage.
Also, if you experience pain or discomfort while using a tampon, it's likely that it wasn't inserted properly, which could lead to menstrual leakage, so try inserting a new one.
The amount of menstrual blood is greater than the tampon can absorb
Even if you use tampons for the correct time, if the size is not correct, menstrual blood may leak.
Like pads, tampons also come in different types, such as for light flow and heavy flow.
If you use light-duty pads on heavy periods, they will exceed the absorption capacity and leak.
If you're leaking even though you're using different tampons, it's possible that your menstrual flow is higher than normal.
Please check the following items.
- Menstruation lasts for more than 8 days
- Liver-like lumps in the bleeding
- Symptoms of anemia such as dizziness and fatigue during menstruation
If any of the items apply to you, it may be a sign of excessive menstruation or an unexpected illness.
If you are unsure, you may want to measure your menstrual flow or consult a gynecologist.

5 ways to prevent tampon leaks from staining your clothes
Here are some ways to prevent menstrual blood from leaking and staining your clothes:
- Use a napkin together
- Stick to the time you use tampons
- Putting the tampon in the right place
- Use a tampon that matches your menstrual flow
By implementing the measures introduced here, you will be able to improve your leakage and feel more comfortable during your period.
Use a napkin together
Using a napkin in combination will prevent menstrual blood from getting on your underwear.
It is recommended to use it in combination with a napkin, especially on the second and third days of your period when your flow is heavier.
If you are not used to using tampons, using them throughout your period will reduce the risk of staining your clothes with menstrual blood.
It's safe to use only tampons during your period once your menstrual blood no longer gets on your pads.
Stick to the time you use tampons
Tampons generally last up to 8 hours, depending on the brand.
If you use the tampon for longer than the recommended time, it may not be able to absorb all the menstrual blood, which may result in leakage.
It is also said that tampon use can easily cause toxic shock syndrome (TSS), but according to the Japan Sanitary Materials Industry Association, the relationship between tampons and TSS is unclear. [1]
However, some studies have shown that the absorbency of tampons may be a contributing factor in cases of TSS in women who use tampons. [1]
Therefore, it is important to protect your body by observing the tampon usage time and using tampons that match your menstrual flow.
If you experience any of the following symptoms, you should seek medical attention immediately: [1]
- Sudden fever
- nausea
- sunburn-like rash
- fainting or fainting-like symptoms
- muscle pain
- dizziness
- Clouding of consciousness
- diarrhea
If you can't change your tampon in time or if it leaks during your period, consider using pads or a menstrual cup.

Putting the tampon in the right place
If the tampon is placed correctly, it will absorb the menstrual flow and prevent leakage.
Tampons with an applicator are convenient when you are not used to using them.
The applicator is the plastic tube on the outside of the tampon that helps guide you to the correct position during insertion.
Also, if you use too much force when inserting, it will put pressure on your stomach and make it harder for the tampon to go in. Take a deep breath and relax before inserting.
Use a tampon that matches your menstrual flow
You can prevent leaks by changing the size of your tampon depending on your menstrual flow. Just like pads, tampons come in different sizes depending on the amount of absorption.
Use the "heavy day" diaper on heavy menstrual flow days and the "normal day" diaper when the flow calms down, depending on the amount of menstrual flow you have.
If you're not sure what size tampon is right for you, we recommend checking frequently for leaks until you get used to it.
What to do if your period leaks after using a tampon: 2 steps
If your period leaks into your underwear, here's what to do:
Step 1: Immediately flush the menstrual flow with water
Step 2: Wash with detergent
If you know the correct way to deal with it, you will be able to calmly deal with the situation even if menstrual blood leaks.
Please feel free to use this as a reference.
Step 1: Immediately flush the menstrual flow with water
If menstrual blood gets on your shorts, rinse them with water below 40°C within a few hours.
Always rinse with water or lukewarm water, as rinsing with hot water will cause the blood proteins to harden and leave stains.
If you are out and about, it is a good idea to moisten a tissue with water and gently wipe only the areas that have menstrual blood on them.
Step 2: Wash with detergent
If washing with water doesn't remove the stain, rubbing it with laundry detergent may remove it.
If the stain won't come out even with laundry detergent, apply oxygen bleach directly to the stain and then wash it in the washing machine.
However, oxygen bleach may cause discoloration, so please test it on an inconspicuous area of the shorts first.
There are also detergents specifically for menstrual blood, so you may want to try using them.
If you're worried about tampon leaks, try a menstrual cup.
If you are worried about menstrual leakage, we recommend using a menstrual cup for the following reasons:
- Can be left in place for up to 12 hours (depending on product)
- If inserted in the correct position, there is little risk of menstrual leakage.
A menstrual cup is a medical silicone or TPE cup inserted into the vagina to collect menstrual blood. If it fits properly in the vagina, menstrual blood rarely leaks out.
The murmo menstrual cup can store menstrual blood for up to 12 hours, making it a great option for when you don't have time to go to the bathroom frequently.
Additionally, many women have reported that using a menstrual cup has relieved their worries about menstrual leakage, saying, "I no longer have to worry about menstrual blood leaking during the day."
If you suffer from leakage, using a menstrual cup may help you feel more comfortable during your period.
