Nimesulide, one of the most consumed anti-inflammatories in Brazil, has its safety questioned in several countries. Despite its popularity in Brazilian lands, where it ranks third among the best-selling medications, this drug is banned in the United States, Canada, Japan, Spain, Ireland, and other countries due to serious health risks, especially related to liver damage.

Nimesulide belongs to the class of non-steroidal anti-inflammatory drugs (NSAIDs) and stands out for its triple action: anti-inflammatory, analgesic, and antipyretic.

This means it can relieve inflammation, pain, and fever, making it a quick and effective option for various clinical conditions.

In Brazil, over 102 million packages of the medication were sold in a single year, according to the consultancy Close-Up International.

This sales volume reflects the frequent use of the substance by patients seeking quick solutions for pain and inflammation. However, experts warn of the dangers of indiscriminate use.

Risks and Side Effects

Despite its effectiveness, nimesulide can cause severe adverse effects. One of the main problems is its association with liver damage, which can occur even in short-term treatments.

Reported symptoms include nausea, vomiting, diarrhea, dizziness, and allergic reactions.

In more severe cases, there may be drug-induced hepatitis, liver failure, and even the need for a liver transplant.

A recent study analyzed 468 cases of drug-induced liver injuries in Latin America, and nimesulide appeared among the drugs associated with the worst prognoses. As a result, authorities in several countries decided to ban or restrict its use.

Why Is Nimesulide Banned in the U.S.?

In the United States, the Food and Drug Administration (FDA), the regulatory agency for medications, has never approved nimesulide due to proven risks of hepatotoxicity.

The decision was based on evidence that the medication can cause liver failure, even at therapeutic doses.

Ireland, for example, immediately suspended the sale of the medication in 2007 after reports of severe cases of liver failure.

Since then, the European Medicines Agency (EMA) has imposed strict restrictions on the use of nimesulide, limiting its prescription to specific cases and for short periods.

Nimesulide in Brazil

Unlike the United States and other countries that have banned the medication, nimesulide remains widely available in Brazil.

The Brazilian Health Regulatory Agency (Anvisa) requires a medical prescription for its acquisition, but experts warn that excessive sales and use still occur without proper oversight.

Hepatologist Raymundo Paraná emphasizes that the culture of self-diagnosis and the ease of purchasing without control are factors that exacerbate the problem.

“Many patients take anti-inflammatories as if they were harmless painkillers, but they forget about the risks to the liver, kidneys, and cardiovascular system”, he warns.

Safe Alternatives

Given the concerns over the safety of nimesulide, experts recommend safer alternatives for pain and inflammation treatment.

Analgesics such as paracetamol and dipyrone are often suggested, as they pose less risk to the liver when used correctly.

Additionally, it is essential that the use of any medication is guided by a healthcare professional to avoid self-medication and its adverse consequences.

Although nimesulide remains available in Brazil, its history of prohibition in several countries, including the United States, raises an important warning.

Indiscriminate use can pose significant health risks, reinforcing the need for greater regulation and awareness of its potential adverse effects.

In light of this, it is crucial for patients to seek medical guidance before using the medication and consider safer options for pain and inflammation treatment.

Creio que se é um medicamento pouco confiável, deveriam banilo do uso no Brasil. EUA, são referências em saúde, entre outros países desenvolvidos.
