Tampon: definition and meaning
A tampon is a small plug of absorbent material, usually cotton, rayon or a blend, that is inserted into the vagina to absorb menstrual blood before it leaves the body. Tampons come in different absorbencies, have a string for removal and should be changed every 4 to 8 hours to lower the rare risk of toxic shock syndrome.
How tampons work
A tampon sits in the vagina, not the cervix or uterus, and expands as it absorbs menstrual flow. Some come with an applicator, others are pushed in with a finger. Once it is in the right place you usually cannot feel it. The string stays outside for removal.
| Absorbency | Roughly holds | Best for |
|---|---|---|
| Light / junior | up to 6 g | light days, first-time users |
| Regular | 6 to 9 g | medium flow |
| Super | 9 to 12 g | heavy days |
| Super plus | 12 to 15 g | very heavy flow only |
Using tampons safely
- Use the lowest absorbency that handles your flow.
- Change every 4 to 8 hours, and never leave one in longer than 8 hours.
- Wash your hands before and after.
- Use pads or period underwear when your flow is very light, rather than a dry tampon.
- Remember to take out the last one at the end of your period.
Remove the tampon and get urgent medical help if you develop a sudden high fever, a sunburn-like rash, vomiting, diarrhea, dizziness or confusion while using one. These can be signs of toxic shock syndrome, which is rare but serious.
Tampons and alternatives
Tampons suit swimming and sport, but they are not the only option. A menstrual cup or menstrual disc can be worn longer and is reusable. See menstrual cup vs tampon and how often to change a tampon.
Frequently asked questions
Can you sleep with a tampon in?
Yes, if you will sleep less than 8 hours and put a fresh one in right before bed. Many people prefer a pad or period underwear overnight.
Can a tampon get lost inside you?
No. The cervix is too small for it to pass into the uterus. If you cannot reach it, a doctor or nurse can remove it quickly.
