Preventing Toxic Shock Syndrome
It's very important that you change your tampon every few hours, even if your period is light. Why? Because leaving one in too long — like all day or all night — puts you at risk for a rare but very dangerous illness called toxic shock syndrome (TSS). That's why it's a good idea to use the least-absorbent tampon you need. That may sound weird. You might think the most-absorbent one would be best because you wouldn't have to change it as often.
But when you keep a tampon in too long, bacteria can grow. Girls who use very absorbent tampons are most at risk for this especially if the tampons are kept in for a long time, giving the bacteria plenty of time to grow. These bacteria can grow within the tampon, enter the body from inside the vagina, then invade the bloodstream, releasing toxins that can cause a very severe, and occasionally life-threatening, illness.
Symptoms of TSS include high fever, vomiting or diarrhea, severe muscle aches, a feeling of extreme weakness or dizziness, and a rash that looks like a sunburn. If you ever have these symptoms while wearing a tampon, remove it and tell an adult immediately. Have someone take you to the nearest emergency department as soon as possible.
But remember that this problem is very rare and most women never become ill from using tampons. When deciding whether to use pads or tampons, it's really up to you. Some girls like tampons because they can go swimming with no problem, and they are easy to store in a purse or pocket. Another advantage to tampons is that they can't be felt because they're inside the body. A pad may feel bulky to some girls.
Other girls like pads because they're easy to use, and it's easier to remember when to change them since you can see them getting soaked with blood. Many girls switch back and forth: Sometimes they use tampons and sometimes they use pads, depending on the situation, where they're going to be, and their menstrual flow. Some use pads at night and tampons during the day. And some girls with heavy periods use tampons together with pads or pantiliners for added protection against leakage. If you have any concerns or questions about your period, talk to your doctor.
Even if you haven't started your period yet, it's a good idea to be prepared by carrying a few pads or tampons with you, just in case. Then, if today is the day, you'll be ready!
