A tampon should never be left in for more than eight hours. Healthcare professionals and manufacturers recommend changing tampons every four to eight hours, depending on your flow, to minimize health risks.
The main concern with a lost tampon is toxic shock syndrome (TSS). This is very rare but can cause death. You should change your tampon regularly — around every 4 to 6 hours depending on your flow. Most tampon manufacturers advise that a tampon shouldn't be left in for more than 8 hours.
The instructions on your tampon box are clear: You should never keep the same tampon in for longer than eight hours. If you leave it in longer than that, you risk toxic shock syndrome and other health concerns.
Never wear a single tampon for more than 8 hours at a time. Use the lowest absorbency tampon needed. If you can wear one tampon up to eight hours without changing it, the absorbency may be too high. Contact your health care provider if you have pain, fever or other unusual symptoms.
Other symptoms may include pain at the site of a wound, vomiting and diarrhea, signs of shock including low blood pressure and light-headedness, shortness of breath and a sunburn-like rash. In general, TSS symptoms can develop as soon as 12 hours after a surgical procedure.
And since you've asked, I have to tell you—aside from the risk of TSS from tampons—there really is no “healthier” choice. What is important is proper use and comfort. You should change your tampons ever 4-6 hours and pads every 2-4 hours.
Vaginal discharge that is a yellow-green colour is not normal. It can indicate an infection in your body, and you should get treatment as soon as possible. The infection could be due to a sexually transmitted infection (STI). These can lead to complications, especially in pregnancy.
What are the symptoms of toxic shock syndrome?
The best way to know if your tampon needs changing is to give a light tug on the tampon string, if it starts to pull out easily then it's time to change, if not, it usually means you can leave it a bit longer. Just remember with tampons, 4 hours is about right, and don't leave one in for more than 8 hours.
You can go about your day, sleep comfortably at night, or even exercise, knowing your blood flow is absorbed and secure. Another reason is comfort. Many people say wearing regular underwear with pads feels bulky or awkward, whereas period pants feel just like everyday undies — but with hidden leak protection.
Overnight rules don't change: 8 hours is the absolute maximum, even if you're sleeping. Don't sleep in a tampon longer than this, as extended wear raises your risk for toxic shock syndrome (TSS) and other health issues. If your sleep schedule makes this tricky, consider using pads or period underwear overnight instead.
The earliest signs of TSS begin abruptly and can present with flu-like symptoms including fever, headache, vomiting, diarrhea and sore muscles.
Menstrual blood on the string: Seeing blood on the string is a sign that you might soon have a leaky tampon. If you notice this, it's probably time to change.
The color of your vaginal discharge can mean there's a problem: Yellow, grey or green: Yellow, grey or green discharge may suggest a bacterial or sexually transmitted infection (STI). Brown or red: Brown or red discharge is usually related to irregular menstruation or pregnancy (implantation bleeding).
Stuck tampon
Tampons should be changed regularly, and should not be left in for more than 8 hours. If a tampon is stuck inside you over a longer period of time, you might start to notice a strong smell from your vagina, and/or an unpleasant discharge.
The three most common menstrual products in Korea are disposable pads, liners, and tampons. The most commonly used of the three are pads.
Tampons are more likely to leak than pads because they can't always absorb all the blood flow. For those with heavy periods, using a combination of tampons and pads can help manage bleeding more effectively. Pads are better at absorbing blood, making them a good choice for people who are worried about leaks.
