We are not doing this in 2026.

If you are teaching a Stop the Bleed class, an Active Shooter response course, an EDC medical block, or any kind of "tactical first aid" curriculum and you are still telling people to carry tampons for gunshot wounds — you are teaching a lie that has been disproven by every credentialed trauma medicine source on the planet. This is not a matter of opinion. It is a matter of physics, anatomy, and manufacturing. And the consequence of getting it wrong is somebody dies on the floor with a cotton plug in their thigh while the femoral artery keeps pumping behind it.

This article is a full-stop reference. Print it. Hand it to the next instructor who insists "I heard guys carried them in [insert war]." Save it for the next online argument. We are killing this myth here.

Credit Where It's Due

We are not the first people to call this out, and we're not pretending to be. The canonical, foundational debunks on the "tactical tampon" myth were already done by people far better credentialed than most of the instructors still teaching it. If you want the long-form primary sources, read these — they are the bedrock this article is built on:

• Andrew D. Fisher, MD, MPAS, PA-C — former 75th Ranger Regiment Physician Assistant, US Army PA of the Year (2010), now a trauma surgeon and one of the most-published authors in tactical and combat trauma medicine. His piece "Your 'Tactical Tampon' is Useless for Life-Threatening Hemorrhage" (Havok Journal, first published February 12, 2019) is the gold standard. In tactical medicine circles, anything Fisher writes is treated as gospel for a reason — he has the combat record, the academic record, and the receipts. Read it.
• Chris, "Hemorrhage Control — What Aunt Flow Didn't Know" (Private Bloggins, January 28, 2015 — original blog now offline, preserved via Crisis Medicine reference list). One of the earliest masterfully written long-form debunks from a Canadian military medic perspective. Chris broke down anatomy, pressure physics, and the comparison between a tampon and a real wound-packing dressing years before this became a mainstream conversation.
• Mike Shertz, MD, EMT-P (Crisis Medicine) — former Special Forces Medical Sergeant (SFMS Class of 1987). His piece "Heavy flow is not massive hemorrhage: Tampons don't stop bullet holes" provides the ballistic-gel pressure data and the institutional military memory we cite throughout this article.
• Dr. Michael "Mike" Simpson, MD — board-certified emergency medicine physician, former 1st Ranger Battalion, then 18C Special Forces Engineer / 18D Special Forces Medical Sergeant (7th Group), then Joint Medical Augmentation Unit (JMAU) / Joint Special Operations Command physician. Retired in 2016 after 32 years of military service (Mike Drop Ep. 76 — "Special Forces Doctor Mike Simpson," October 30, 2021; Three Rangers Foundation profile). Simpson served as Global Clinical Advisor for Safeguard Medical (Safeguard Medical's official channel) and is one of the most credentialed voices in tactical trauma medicine working today (drmikesimpson.com). He has stepped back from public social media in recent years, but the body of clinical and educational work he produced — including his lectures and training content as Safeguard's clinical lead — sits squarely in the same camp as Fisher and Shertz on tampons.

If you teach Stop the Bleed or any active-shooter / civilian-casualty curriculum and you haven't worked through this body of work — you are not qualified to argue this point. Read them, then come back.

Where The Myth Actually Comes From

The "tampons stop bullet holes" story is one of the most resilient zombie myths in modern medical folklore. Trace it back and you find three threads, none of which support carrying tampons today.

Thread 1 — World War I, and it runs the opposite direction. Kimberly-Clark produced an absorbent wood-pulp wadding called Cellucotton during WWI as a surgical dressing because cotton was scarce. Field nurses in France started using leftover Cellucotton pads as disposable menstrual pads, and that's how the modern feminine hygiene industry was born (Andrew Fisher, MD; cited in Crisis Medicine). The product moved from battlefield to bedroom — not the other way around. The modern internal tampon was patented in 1933 and was never intended for trauma at any point.

Thread 2 — Vietnam-era barracks talk. There are a handful of anecdotes about Vietnam-era medics or grunts carrying tampons. None of them are documented in any military medical record, any after-action review, or any peer-reviewed publication. Mike Shertz, who went through the Special Forces Medical Sergeant's Course in 1987 and now runs Crisis Medicine, has stated plainly that during his SFMS training the instructors had tried tampons for hemorrhage control and told the students they were "never effective" (Crisis Medicine). That's the closest you get to an official military assessment, and it's a "no."

Thread 3 — GWOT and after. This is the most often repeated and the most demonstrably false thread. There is no verified, documented evidence that US, UK, Australian, or Canadian service members in Iraq, Afghanistan, Syria, or any other Global War on Terror theater carried or were taught to use tampons for hemorrhage control. Andrew D. Fisher, MD — author of the canonical Havok Journal piece "Your 'Tactical Tampon' is Useless for Life-Threatening Hemorrhage" — has independently searched the medical literature and the historical record and "yet to find any confirmable example of tampons ever being used as treatments for life-threatening wounds" (Coffee or Die / Andrew Fisher, MD). Police1's deep dive on the topic reached the same conclusion: searching medical literature and journals, the author was "unable to find even a single instance of a tampon being used to stop bleeding from trauma" (Police1).

The current crop of anecdotes — vague references to soldiers in Ukraine or Russia carrying them — are exactly that: anecdotes. The fact that somebody, somewhere, in a desperate situation, with no IFAK, shoved a tampon into a wound does not mean it worked, does not mean the patient lived because of the tampon, and absolutely does not mean it should be on your packing list in 2026.

Anecdote is not evidence. Carrying something into a war zone is not proof that it works.

What A Tampon Actually Is

Before we explain why tampons cannot stop hemorrhage, let's look at what one actually is. Most people teaching the myth have never opened one up and examined it next to a real piece of trauma kit.

A standard tampon is a small compressed cylinder of cotton, rayon, or a blend, approximately 1.5 to 2 inches long and roughly half an inch in diameter when packaged, with a withdrawal cord. When fully unfurled and opened, the interior absorbent is the equivalent of approximately two 2-inch by 4-inch pieces of light cotton gauze (Crisis Medicine).

Absorbency is regulated by the US FDA under 21 CFR 801.430 and labeled by mass of fluid absorbed:

That's it. The absolute upper bound of FDA-allowed tampon absorbency is 18 grams of fluid — about one tablespoon and one teaspoon (21 CFR 801.430; FDA absorbency labeling). The Police1 medical reviewer cites the practical real-world average as roughly 9 mL of blood for a standard tampon (Police1).

Tampons are also not sterile. The FDA classifies them as Class II "sanitary" medical devices, not sterile surgical products (National Center for Health Research). They are designed to be inserted into the vagina to passively absorb menstrual fluid over the course of hours. That is the only thing they are engineered to do.

What Hemorrhage Actually Is

Now compare those numbers to what an actual bleeding wound produces.

The human body holds roughly 5 liters (5,000 mL) of blood in a normal-sized adult. Class III hemorrhagic shock — the threshold for profound, compensated shock — begins around 1,500 mL of blood loss (about 30% of total blood volume). At that level, compensatory mechanisms are failing and the patient is heading for cardiovascular collapse.

A severed femoral artery — the classic "junctional bleed near the groin" — can lose between 500 and 1,500 mL of blood per minute (Andrew Fisher, MD, in Coffee or Die). At the high end, you go from healthy to dead in under three minutes.

Now put those numbers side by side:

A standard tampon can absorb roughly 9 mL of fluid. A femoral artery can pump that out in under one second. The math is not close. It's not even in the same universe.

Why Pressure — Not Absorption — Stops Hemorrhage

The single most important concept that the tampon myth ignores is how bleeding is actually controlled. Bleeding control is not a sponge problem. It is a pressure problem.

When a vessel is torn open, blood is being pushed out by the patient's own arterial blood pressure — typically 70 to 120 mmHg of systolic pressure for a hemorrhaging adult, higher for younger and fitter patients. To stop that flow, you have to either close the vessel mechanically (tourniquet, vascular clamp, surgical repair) or apply counter-pressure inside the wound greater than the patient's arterial pressure while the body forms a clot.

That is exactly what wound packing with rolled gauze does. In a ballistic gel wound model of a 53-mL wound cavity, well-trained combat medics packing a Kerlix-style rolled gauze produced 156 mmHg of pressure at the bleeding site — more than enough to overcome the patient's arterial pressure and allow clotting to occur (NAMRU-SA technical report cited in Crisis Medicine).

A tampon cannot do this. Even when fully expanded, a tampon is small, soft, and has no surface area to redistribute force against the wound tract. Plugging the entrance hole with a tampon often just stretches the skin around it and seals the visible wound — while the patient continues to hemorrhage internally into the cavitation tract (PracMed NZ). You will see less blood on the floor. The patient will deteriorate anyway. You will be confused. They will die.

Tampon vs Rolled Gauze: The Direct Comparison

This is the comparison that should be done in every Stop the Bleed class that mentions tampons. Open the tampon. Open a single roll of standard combat gauze. Lay them next to each other on the table.

By absorbent mass, a single roll of standard combat gauze contains roughly 40 times the absorbent material of a single tampon. By useful in-wound pressure, the gauze produces something measurable in mmHg while the tampon produces functionally zero.

This is the side-by-side that ends the argument every time it is done in an actual classroom. If you are teaching this material, do that demonstration on day one.

The "If It's All You Have" Argument Is Also Wrong

The fallback argument from people who can't quite let go of the tampon is, "But if it's all you have, you should still use it." That argument is also incorrect, and it is incorrect from the highest authority in American civilian trauma care.

The American College of Surgeons Stop the Bleed program has specifically addressed this. ACS guidance is unambiguous: if a hemostatic dressing, sterile dressing, or commercial tourniquet is not available, the correct improvised material is clothing — a shirt, a pants leg, a sock — used as a manual pressure source or wound packing (American College of Surgeons / Stop the Bleed; cited in EMJ response, Police1).

In other words: a sweaty T-shirt is a better hemorrhage control material than a tampon. Read that again. According to the people who write the actual curriculum, a sock off your foot is a better choice than the tampon in your pocket.

It gets worse for the tampon. Multiple authors have pointed out that tampons:

• Are designed to absorb blood, which can interfere with the body's normal clotting cascade by wicking clotting factors away from the wound (Police1).
• Disintegrate when saturated, leaving cotton fragments inside the wound tract that complicate surgical repair.
• Adhere to the wound tract once partially dry, making removal far more traumatic than rolled gauze, which is designed to be repacked.
• Are typically smaller than the exit wound of any meaningful caliber, meaning a single tampon cannot fill the destruction tract behind the visible entrance hole (PracMed NZ).

The "emergency-only fallback" position is itself unsupported by the evidence. The honest answer is: there is no situation in which a tampon is the correct trauma intervention. Not as primary. Not as backup. Not as last resort.

What We Teach Instead — The MED-TAC Hemorrhage Control Stack

This is what every responsible Stop the Bleed, civilian preparedness, LE patrol-level medical, and EMS curriculum should be teaching in 2026. None of it is new. All of it is proven.

1. Direct pressure with gloved hands or any clean material against the bleeding source. Pressure first, always.
2. Tourniquet for any life-threatening extremity hemorrhage. A CoTCCC-recommended limb tourniquet (CAT, SOFTT-W, TMT) applied 2 to 3 inches above the wound, tightened until distal pulse is gone, time-marked. Tourniquets do not cause limb loss in any realistic prehospital window.
3. Wound packing with rolled gauze — ideally hemostatic gauze (kaolin- or chitosan-based) for junctional wounds (groin, axilla, neck) and any wound a tourniquet cannot reach. Pack tight, pack deep, pack to the source of bleeding. Hold pressure for at least 3 minutes.
4. Pressure dressing (Israeli-style emergency bandage, OLAES, ETD) over the packed wound to maintain compression while the patient is moved.
5. Hypothermia prevention and rapid transport to a surgical capability.

Every one of those steps is in the American College of Surgeons Stop the Bleed program, the Committee on Tactical Combat Casualty Care guidelines, and every credible civilian and military trauma curriculum. None of them involve a tampon.

If you are running a class and you are not teaching this stack, you are running the wrong class. If you are running a class and you are still teaching the tampon, you are actively making your students worse at saving lives.

A Direct Message To Instructors

We respect that some of you are volunteering your time. We respect that some of you came up through entry-level programs and inherited the tampon talking point from somebody you trusted. We are not interested in fighting with you. We are interested in your students living through the next bad day.

So here is the message:

• Open the box. Take a tampon out of its wrapper. Take a roll of rolled gauze out of its wrapper. Set them next to each other in front of your class. Let your students look. Then teach the rest of the class with the gauze.
• Drop the GWOT story. It isn't true and you do not need it. The case for proper wound packing stands entirely on physics and physiology — you do not need to lean on a fabricated war story to make the point.
• Read the canonical sources at least once before your next teach: Crisis Medicine, Coffee or Die / Dr. Andrew Fisher, PracMed NZ, and Police1.
• Get into a real instructor course. Stop the Bleed instructor certification through ACS is free. If you want to teach LE/Active Shooter-adjacent medical content, get into a TCCC, TECC, or TEMS provider course taught by people with actual trauma credentials. Stop self-credentialing on YouTube.

If you carry a kit, that kit should contain a CoTCCC-recommended tourniquet, hemostatic-impregnated rolled gauze, a vented chest seal, a pressure dressing, a nasopharyngeal airway, and gloves. That is the inventory of a kit that saves lives. The tampon does not appear on that list — not as primary, not as backup, not as last resort. Build a kit that works.

Bottom Line

A tampon is a piece of compressed cotton or rayon designed to passively absorb up to 18 grams of menstrual fluid over the course of several hours, inside an environment that is anatomically nothing like a gunshot wound. It is not sterile. It contains a fraction of the absorbent material of one roll of rolled gauze. It produces no useful in-wound pressure. It does not contain any hemostatic agent. It is smaller than the exit wound of essentially any centerfire round. It will hide cavitation bleeding while the patient continues to exsanguinate internally. It can interfere with normal clotting. It adheres and disintegrates and is harder to remove than rolled gauze. And — at the highest level of authority — even the American College of Surgeons says a sweaty piece of clothing is a better improvised wound-packing material.

We are done having this conversation in 2026. Stop teaching it. Stop carrying it as your "tactical" plan. And if somebody else is still teaching it — share this article and end the argument.

Tampones No Detienen Hemorragias: El Desmentido Definitivo de 2026 Que Todo Instructor Debe Leer

No vamos a hacer esto en 2026.

Si usted está enseñando una clase de Stop the Bleed, un curso de respuesta a tirador activo, un bloque de medicina EDC o cualquier currículo de "primeros auxilios tácticos" y todavía le está diciendo a la gente que cargue tampones para heridas de bala — está enseñando una mentira que ha sido refutada por toda fuente acreditada de medicina de trauma del planeta. Esto no es opinión. Es física, anatomía y manufactura. Y la consecuencia de equivocarse es que alguien muere en el piso con un tapón de algodón en el muslo mientras la arteria femoral sigue bombeando detrás.

Crédito A Quienes Ya Mataron Este Mito

No somos los primeros en señalarlo. Los desmentidos canónicos del mito del "tampón táctico" ya fueron escritos por personas mucho más acreditadas que la mayoría de los instructores que aún lo enseñan. Léalos:

• Andrew D. Fisher, MD, MPAS, PA-C — ex Physician Assistant del 75th Ranger Regiment, PA del Año del US Army (2010), cirujano de trauma y uno de los autores más publicados en medicina táctica y de combate. Su artículo "Your 'Tactical Tampon' is Useless for Life-Threatening Hemorrhage" (Havok Journal, 12 febrero 2019) es el estándar de oro. En círculos de medicina táctica, lo que escribe Fisher se considera doctrina por una razón.
• Chris, "Hemorrhage Control — What Aunt Flow Didn't Know" (Private Bloggins, 28 enero 2015 — blog original fuera de línea, preservado vía Crisis Medicine). Uno de los primeros desmentidos masterfully escritos desde una perspectiva canadiense de médico militar.
• Mike Shertz, MD, EMT-P (Crisis Medicine) — ex Special Forces Medical Sergeant (clase SFMS 1987). Su artículo en Crisis Medicine aporta los datos de presión en gel balístico y la memoria militar institucional.
• Dr. Michael "Mike" Simpson, MD — médico de emergencias certificado, ex 1st Ranger Battalion, luego Special Forces Engineer (18C) y Medical Sergeant (18D) del 7° Grupo, y luego médico de la Joint Medical Augmentation Unit (JMAU) del Joint Special Operations Command. Retirado en 2016 tras 32 años de servicio (Mike Drop Ep. 76 — "Special Forces Doctor Mike Simpson," 30 octubre 2021; Three Rangers Foundation). Simpson se desempeñó como Global Clinical Advisor para Safeguard Medical (canal oficial de Safeguard Medical) y es una de las voces más acreditadas en medicina de trauma táctico (drmikesimpson.com). Ha tomado un paso atrás de las redes sociales en los últimos años, pero su cuerpo de trabajo clínico y educativo — incluyendo sus conferencias y contenido de entrenamiento como líder clínico de Safeguard — está firmemente en el mismo campo que Fisher y Shertz sobre los tampones.

Si enseña Stop the Bleed o cualquier currículo de respuesta a tirador activo y no ha trabajado a través de este cuerpo de trabajo, no está calificado para defender esta postura. Léalos y vuelva.

De Dónde Viene Realmente El Mito

El mito tiene tres hilos históricos y ninguno apoya cargar tampones hoy.

1. Primera Guerra Mundial — y va en sentido contrario. Kimberly-Clark produjo un material absorbente de pulpa de madera llamado Cellucotton como apósito quirúrgico. Las enfermeras lo reutilizaron como toallas sanitarias improvisadas. Así nació la industria moderna de higiene femenina (Crisis Medicine). El producto pasó del campo de batalla al baño — no al revés.
2. Vietnam — anécdotas, no registros. Hay un puñado de anécdotas de medics o soldados cargando tampones en Vietnam. Ninguna está documentada en registros médicos militares, AAR ni literatura revisada por pares. Mike Shertz, instructor del curso de SF Medical Sergeant en 1987, declaró que los instructores ya habían probado tampones para hemorragias y los consideraron "nunca efectivos."
3. GWOT — no hay evidencia. No existe evidencia verificada y documentada de que miembros del servicio estadounidense, británico, australiano o canadiense en Irak, Afganistán, Siria u otro teatro de la Guerra Global Contra el Terrorismo cargaran o usaran tampones para control de hemorragia. El Dr. Andrew Fisher buscó en la literatura médica y el registro histórico y no encontró un solo ejemplo confirmable (Coffee or Die).

Una anécdota no es evidencia. Cargar algo a una zona de guerra no prueba que funcione.

Qué Es Realmente Un Tampón

Un tampón es un cilindro de algodón o rayón comprimido, de aproximadamente 1.5 a 2 pulgadas de largo y media pulgada de diámetro, con un cordón de retiro. Al desplegarse, el material absorbente equivale aproximadamente a dos piezas de gasa de 2" × 4" (Crisis Medicine).

La FDA regula la absorbencia bajo 21 CFR 801.430. El máximo permitido es 18 gramos de fluido (FDA, 21 CFR 801.430). En la práctica, un tampón estándar absorbe alrededor de 9 mL (Police1). Los tampones no son estériles — son dispositivos médicos clase II sanitarios, no quirúrgicos.

Qué Es Realmente Una Hemorragia

El cuerpo humano adulto contiene aproximadamente 5,000 mL de sangre. La hemorragia clase III, umbral del choque hemorrágico profundo, comienza alrededor de 1,500 mL perdidos (~30% del volumen total).

Una arteria femoral seccionada puede perder entre 500 y 1,500 mL por minuto (Coffee or Die). En el extremo alto, va de sano a muerto en menos de tres minutos.

Un tampón absorbe ~9 mL. Una femoral lo bombea en menos de un segundo. La matemática no se acerca.

Por Qué Lo Que Detiene Una Hemorragia Es La Presión, No La Absorción

El control de hemorragia no es un problema de esponja — es un problema de presión.

Al empacar una herida con gasa enrollada estándar tipo Kerlix, medics entrenados generan aproximadamente 156 mmHg de presión en el sitio sangrante en un modelo de gel balístico de 53 mL (NAMRU-SA / Crisis Medicine). Eso supera la presión arterial del paciente y permite que se forme el coágulo. Un tampón no puede producir esa presión. Tapar la herida con un tampón a menudo solo estira la piel alrededor del orificio visible mientras el paciente sigue sangrando hacia el tracto interno de cavitación (PracMed NZ).

Tampón Vs Gasa Enrollada — La Comparación Directa

Una sola gasa enrollada contiene aproximadamente 40 veces el material absorbente de un tampón.

El Argumento "Es Lo Único Que Tengo" También Está Mal

El Colegio Americano de Cirujanos ha sido explícito: si no tiene gasa hemostática, gasa estéril ni torniquete comercial, el material improvisado correcto es ropa — una camiseta, una pierna de pantalón, un calcetín (American College of Surgeons / EMJ). Una camiseta sudada es mejor material de empaque de herida que un tampón. Léalo otra vez.

Adicionalmente, los tampones absorben sangre — lo que puede interferir con la cascada normal de coagulación (Police1) — se desintegran al saturarse, se adhieren al tracto al secarse, y son típicamente más pequeños que el orificio de salida de cualquier calibre centerfire significativo.

Lo Que Enseñamos En Cambio — La Pila MED-TAC De Control De Hemorragia

1. Presión directa primero, siempre.
2. Torniquete para hemorragia de extremidad — CAT, SOFTT-W o TMT (recomendados por CoTCCC), 2–3 pulgadas arriba de la herida, apretar hasta perder pulso distal, marcar la hora.
3. Empaque de herida con gasa enrollada — idealmente hemostática (kaolín o chitosan) — para heridas junturales (ingle, axila, cuello) y heridas no torniquetables. Empaque apretado, profundo, hasta la fuente. Mantenga presión al menos 3 minutos.
4. Vendaje de presión (Israeli, OLAES, ETD) sobre la herida empacada para mantener compresión durante el transporte.
5. Prevención de hipotermia y transporte rápido a capacidad quirúrgica.

Todos están en el programa Stop the Bleed del ACS y en las guías del Committee on Tactical Combat Casualty Care. Ninguno involucra un tampón.

Mensaje Directo A Instructores

• Abra la caja. Saque un tampón del empaque. Saque una gasa enrollada. Póngalas lado a lado frente a su clase. Deje que sus estudiantes vean. Después enseñe el resto de la clase con la gasa.
• Suelte la historia GWOT. No es verdad y no la necesita. El caso por empaque adecuado de herida se sostiene completamente en física y fisiología.
• Lea las fuentes canónicas antes de su próxima clase: Crisis Medicine, Coffee or Die / Dr. Andrew Fisher, PracMed NZ, Police1.
• Entre a un curso real de instructor. La certificación de instructor Stop the Bleed del ACS es gratis. Para contenido de tirador activo / médico LE, busque TCCC, TECC o TEMS impartidos por personal con credenciales reales de trauma.

Si carga un kit, ese kit debe contener torniquete recomendado por CoTCCC, gasa enrollada hemostática, sello de tórax ventilado, vendaje de presión, cánula nasofaríngea y guantes. El tampón no aparece en esa lista. Construya un kit que funcione.

Conclusión

Un tampón absorbe hasta 18 g de fluido menstrual durante horas, en un ambiente anatómicamente nada parecido a una herida de bala. No es estéril. Contiene una fracción del material absorbente de una sola gasa enrollada. No produce presión útil dentro de la herida. No contiene agente hemostático. Es más pequeño que el orificio de salida de virtualmente cualquier calibre centerfire. Esconde sangrado por cavitación mientras el paciente sigue exsanguinándose internamente. Puede interferir con la coagulación. Se adhiere y se desintegra. Y — al más alto nivel de autoridad — incluso el Colegio Americano de Cirujanos dice que una pieza de ropa sudada es mejor material improvisado de empaque que un tampón.

Terminamos con esta conversación en 2026. Dejen de enseñarlo. Dejen de cargarlo como su "plan táctico." Y si alguien más lo sigue enseñando — comparta este artículo y termine el argumento.
