Discover Why Dipyrone Is Banned in Several Countries but Permitted in Brazil. Understand the Risks, Benefits, and Controversies of This Medication.

You have probably taken dipyrone or know someone who has. It’s the little medicine that resolves headaches, fevers, colics, toothaches, and even muscle pains. But what few people know is that this medication is banned in several countries around the world. Meanwhile, in Brazil, dipyrone is sold without a prescription at any pharmacy.

But after all: why is this so popular medicine here banned abroad? Is it dangerous? Or is the rest of the world being exaggerated?

Let’s understand!

What Is Dipyrone and Why Is It So Widely Used?

Dipyrone (or metamizole, its technical name) is an analgesic and antipyretic, meaning it serves to relieve pain and reduce fever. It is found in medications such as Novalgina, Anador, Maxalgina, among others.

It is known for being:

Fast
Inexpensive
Effective

In Brazil, it is even used in hospitals, including intravenously, and is highly recommended for stronger pains or persistent fevers.

Why Is Dipyrone Banned in Other Countries?

The reason for the ban is linked to a rare but dangerous side effect, called agranulocytosis.

What Is That?

It is a reaction that attacks white blood cells, cells that protect the body against infections. When they diminish, the body becomes vulnerable to severe infections, which can even lead to death.

This risk has led countries such as:

United States
United Kingdom
Japan
Sweden
Australia

banned or heavily restricted dipyrone. In these places, doctors prefer medications like paracetamol and ibuprofen, which have less history of serious adverse effects.

And Why Does Brazil Continue to Use It?

Because, according to local studies, cases of agranulocytosis here are extremely rare. The Anvisa (National Health Surveillance Agency) considers the medication safe when used correctly.

In addition:

Dipyrone is very effective.
It is an affordable option for the population.
And Brazilian doctors are accustomed to its use.

That is why it continues to be sold without a prescription, which even impresses foreigners visiting the country.

So… Is Taking Dipyrone Safe?

For the vast majority of people, yes — especially if used in the correct doses and for the indicated time. But it is always important to:

Read the patient information leaflet
Avoid prolonged self-medication
Consult a healthcare professional if symptoms persist

Dipyrone is considered safe in Brazil, in part, because of the genetic profile of the population, which seems to have a lower predisposition to severe reactions like agranulocytosis.

This risk can vary significantly among different countries and populations, which explains why the medication is allowed in some places and banned in others.

Dipyrone is a curious case: hated by some, loved by others. For some countries, it is poison; for Brazil, it is a solution. The most important thing is to be well-informed and always use any medication responsibly.

So, did you already know about this whole controversy?

Enquanto isso, o paracetamol continua sendo vendido nos EUA. Na Inglaterra, somente com receita médica e até 10 comprimidos por receita. Isso por conta de uma hepatite fulminante que ele pode provocar, inclusive com necrose do tecido hepático.
Tem gente que utiliza isso para “to kill oneself” em dosagens únicas elevadas.
Não devemos nos esquecer de outro produto hepatotóxico, o aspartame, 10 vezes mais prejudicial do que o ciclamato e a sacarina,que são proibidos nos EUA desde o início dos anos 70.

The Soviet Union spent 22 years drilling into the Earth’s crust and reached a depth of 12,262 meters — they found water where it was thought impossible, hydrogen bubbling from the rock, granite that is 2.7 billion years old, and temperatures of 180 degrees that melted the drill bits.

Ethiopia has banned gasoline and diesel cars, placed over a hundred silent electric buses on the streets of Addis Ababa, and now aims for half a million electric vehicles by 2030, all powered by Africa’s largest dam and a courage that few countries have shown.

Egypt wants to draw 10 million cubic meters of water from the Nile per day into the desert, irrigate a new agricultural frontier, and build a city where there is currently only sand.

Norway is drilling 27 kilometers of rock 392 meters below the bottom of a fjord to build the world’s largest and deepest underwater road tunnel — when completed, a 21-hour journey will be reduced to 10.

An astronaut spent 340 days in space while his twin brother stayed on Earth, and NASA found a “rejuvenating” effect, genes, microbiome, cognition, and immune system that revealed the biological cost of living outside the planet.

Chinese engineers begin filling a 217-meter dam at an altitude of 3,000 meters and prepare a 2,240 MW hydroelectric power plant to integrate hydropower, solar, and wind energy in the upper Jinsha.

Researchers walked 4.6 kilometers through the sertão of Paraíba and found hundreds of rock carvings scattered across rocks — what could be Brazil’s largest archaeological site was hidden on a rural property 20 km from Catolé do Rocha.

Canadian company drills almost 100 km of wells up to 4.5 km deep, transforms an abandoned geothermal field into a giant underground radiator, and enables Germany to receive electricity from a closed-loop geothermal system on the public grid for the first time.

11 consecutive years among the hottest ever recorded place the planet at a new level of alert, and the World Meteorological Organization points out that extreme heat, intense rainfall, cyclones, and melting ice are already pressuring economies, cities, and supply systems on a global scale.

A United States soldier who was on the mission to capture Nicolás Maduro bet hours before the official announcement, profited over US$400,000 on a prediction platform, and now faces federal charges.

More than 100 scientists warn that India, China, the United States, Mediterranean countries, and parts of Africa could enter an era of persistent droughts by the end of the century, with rivers under stress, demand exceeding supply, and a growing risk of continuous water scarcity.
