How to Use a Tampon: A Plain Guide, and the Safety Part Told Straight

The NHS describes a tampon in about three lines, and the rumour about toxic shock is much longer than the evidence. This page prints the symptoms, the emergency line and the measured numbers, and refuses to invent the one figure everybody else gives you.

Wash your hands, read the leaflet in the box, and put it in. That really is the whole method, and the NHS's own description of a tampon is just as short: small tubes of cotton wool that you insert into your vagina to soak up the blood, in two types, with an applicator and without. Two things a lot of people worry about have flat answers. It cannot get lost inside you — the NHS says your vagina holds it firmly in place. And toxic shock syndrome, the thing everyone has heard a rumour about, is described by the NHS as rare but life-threatening: active surveillance around Minneapolis-St. Paul from 2000 to 2006 measured menstrual cases at 0.69 per 100,000 a year, and 1.41 per 100,000 among women aged 13 to 24. Both halves of that are on this page, with the symptoms to act on.

This is for someone about to try one for the first time, possibly in a hurry, possibly in a school toilet. Nothing here is a brand and nothing here is a recommendation.

What a tampon is, in one paragraph

Small tubes of cotton wool, inserted into the vagina, which soak up the blood before it leaves your body. There are two types. One comes inside an applicator, a smooth tube that you use to push the tampon in and then throw away. The other has no applicator and goes in with a finger. Both do the same job; the NHS presents them as two types rather than as a beginner version and an advanced one.

They are one of four things the NHS names as safe and suitable if you have just started — alongside menstrual cups, disposable or reusable pads, and period underwear. If you have not settled on anything yet, period products explained lays all of them out side by side on the only property anyone has measured, which is how much each one holds. Even there, the figures are patchy: the 2023 review in Obstetrics & Gynecology that this site quotes estimates a fully saturated super pad at about 5ml, a nighttime pad at up to 15ml, cup basins at 8ml to 37ml measured to the suction-release holes and disc basins at 30ml to 79ml, and a tampon is not among the numbers it can be quoted on.

The steps, and the ones this page hands back to the box

Here is the honest structure of this section: some of it is published advice and some of it is a leaflet you already own, and it is worth knowing which is which.

Wash your hands. This is not a politeness. It is one of the two things the NHS names to lower the chance of toxic shock syndrome, the other being to follow the instructions.

Read the instructions that came with it. Every packet has them, they are specific to the product in your hand, and the NHS's advice is to follow them. That includes the bit about angle and depth. This page will not draw you a diagram, because no publisher it is allowed to stand on has drawn one, and a made-up diagram is worse than no diagram.

Get comfortable and take your time. Sitting on the toilet or standing with one foot up are the usual suggestions, and they are suggestions rather than findings — nobody has run a study on position. If it will not go in, nothing has gone wrong and there is no time limit. Stop, use a pad instead, and try again on another day. A first attempt that does not work is the most ordinary outcome there is.

Take it out by the string. The string stays outside your body and that is what it is for.

Two of those steps are the NHS's and three of them are practical common sense that this page is labelling as such, rather than dressing up as evidence.

It cannot get lost inside you

This is worth its own heading because it is the fear that stops most people trying, and it has a one-line answer from the NHS: it is not possible for a tampon to get lost inside you, because your vagina holds it firmly in place. There is no route from there to anywhere else in your body.

What can happen is that the string is hard to find or the tampon feels stuck, which is not the same problem and is not an emergency. Wash your hands and try again, relaxed rather than rushed. If it still will not come out, this is a thing to say out loud to a person rather than to a search engine — the NHS's own framing for this age is to talk to your parent or another adult you trust, and a pharmacist or a GP has heard the question many times before. It is a short conversation.

Toxic shock syndrome, told straight

The NHS calls it a rare but life-threatening condition that can happen when using a tampon or a menstrual cup, or from an infected wound. Neither word in "rare but life-threatening" is decoration, and leaving either one out is how this subject gets told badly.

Early symptoms

A high temperature or feeling hot, cold or shivery. Muscle aches. A raised skin rash that feels like sandpaper.

Call 999 or go to A&E

Blue, grey, pale or blotchy skin. A rash that does not fade. Difficulty breathing. Large areas of peeling skin.

And if you are using a tampon or menstrual cup, remove it.

Measured rate, for scale: active population-based surveillance of the Minneapolis-St. Paul area from 2000 to 2006 found 61 cases of staphylococcal toxic shock syndrome, 33 of them menstrual — an average annual incidence of 0.69 per 100,000, and 1.41 per 100,000 among women aged 13 to 24, the highest of any group.

The rest of that surveillance paper is the part that explains why your mother or your grandmother may sound more frightened about this than the numbers warrant. It reports that by 1986 the rates of menstrual and non-menstrual cases were 1 and 0.3 per 100,000, down from a 1980 peak of 13.7 per 100,000 among young menstruating women, a fall that followed the removal of high-absorbency tampons from the market. The rumour going round school is a memory of 1980, and the products it was about are not on the shelf.

What the NHS says to do about it in advance is short and this page will not embellish it: wash your hands, follow the instructions when using tampons and menstrual cups, and do not leave them in longer than needed or recommended.

How many hours? The box, and only the box

You will find a confident number for this on almost every other page you open, and there is not one here. Nothing this site is allowed to cite publishes a figure. The NHS publishes a rule instead — do not leave them in longer than needed or recommended, and follow the instructions — and "recommended" means the leaflet that came with the specific product you bought.

So read it once and remember it, or photograph it. That is a duller answer than a number, and it is the only one that is actually about the tampon you are holding. The same rule applies to a cup, which is why menstrual cups, honestly reaches the same dead end from the other direction. It applies in a swimming pool too, exactly as it does anywhere else — see swimming on your period.

How fast you go through them is worth noticing

One number about tampons does have a published threshold attached, and it is not about safety so much as about your own body. The NHS lists needing to change your pad or tampon every 1 to 2 hours among the signs of heavy periods, alongside using 2 types of period product together, periods lasting more than 7 days, passing blood clots larger than about 2.5cm, and bleeding through to your clothes or bedding. It also says many women have heavy periods and they may be normal for you, and that they can be heavier at different times, such as when periods first start.

Both sentences at once, then. Going through a lot is common, and it is still worth mentioning if it is affecting your life. Leaking is a related and separate annoyance with practical fixes — period leaks covers that without treating it as a catastrophe, because it is not one.

The way to make any of this useful to a doctor is to write it down while it is happening. The printable period tracker holds the start dates and the length of each period, which is where the "more than 7 days" test comes from, and it keeps nothing anywhere. Two cycles of that is a better answer to "how heavy are they?" than anything you can reconstruct at a desk.

And if you are building a bag rather than a medical record, the first period kit checklist is five minutes' work. The NHS's advice for the day you get caught out without anything is to ask a teacher or the school nurse, which is an ordinary request rather than an admission of anything.

Questions

Questions people ask

Wash your hands, which the NHS names as one of the two things that lower the chance of toxic shock syndrome, and read the instructions that came in the packet, which is the other. The NHS describes two types, with an applicator and without; the applicator is a tube you use to push the tampon in and then throw away. The string stays outside your body and is how you take it out. If it will not go in, use a pad and try another day. No publisher this site cites publishes a diagram, so this site does not draw one.
No. The NHS says plainly that it is not possible for a tampon to get lost inside you, because your vagina holds it firmly in place. There is no route from there into the rest of your body. A string that is hard to find, or a tampon that feels stuck, is a different and much smaller problem, and it is not an emergency. Wash your hands and try again unhurried, and if it still will not come out, say so to an adult you trust, a pharmacist or a GP.
This page does not give a number, and the reason is that no publisher it is permitted to cite gives one. The NHS publishes a rule rather than a figure: follow the instructions when using tampons and menstrual cups, and do not leave them in longer than needed or recommended. What counts as recommended is on the leaflet in the box you bought, because it is specific to that product. Read it once and photograph it. Any web page quoting a number instead has substituted a guess for the manufacturer.
Rare, and measured. Active population-based surveillance of the Minneapolis-St. Paul area from 2000 to 2006 identified 61 cases of staphylococcal toxic shock syndrome, 33 of them menstrual, giving an average annual incidence of 0.69 per 100,000 and 1.41 per 100,000 among women aged 13 to 24, the highest of any group. The same surveillance reports a 1980 peak of 13.7 per 100,000 among young menstruating women, which fell after high-absorbency tampons were removed from the market. The NHS still calls the condition rare but life-threatening, and both words matter.
The NHS lists early symptoms as a high temperature or feeling hot, cold or shivery, muscle aches, and a raised skin rash that feels like sandpaper. It says to call 999 or go to A&E for symptoms such as blue, grey, pale or blotchy skin, a rash that does not fade, difficulty breathing, or large areas of peeling skin — and that if you are using a tampon or menstrual cup, you should remove it. Toxic shock syndrome can also follow an infected wound rather than a period product.
Often, yes. The NHS says many women have heavy periods, that they may be normal for you, and that periods can be heavier at some times than others, including when they first start. It also gives a threshold worth knowing: needing to change a pad or tampon every 1 to 2 hours is on its list of signs of heavy periods, alongside using 2 types of product together, periods lasting more than 7 days and bleeding through to your clothes or bedding. Worth raising at an appointment if it is affecting your life.
