AIFA Issues Warning: Metamizole Linked to Serious Side Effects, Sparking Concern Among Italians
The Italian Medicines Agency (AIFA) has issued a stark warning about the potential dangers of metamizole, an active ingredient found in widely used medications like Novalgina and its generic counterparts. Known for its antipyretic and analgesic properties, metamizole has been flagged for causing a rare but severe side effect: agranulocytosis. This condition, characterized by a drastic drop in granulocytes—a type of white blood cell crucial for fighting infections—can leave the body vulnerable to bacterial and fungal infections.
The symptoms of agranulocytosis can mimic those of the flu, including fever, sore throat, and chills.AIFA urges anyone undergoing treatment with metamizole to consult their doctor immediately if these symptoms arise. Professor Pierluigi Navarra, speaking to Fatto Quotidiano, emphasized the gravity of the situation: “Metamizole is part of a class of drugs that has been withdrawn some time ago. It was also administered in the form of drops, as it was thought to be less harmful to the gastric mucosa.”

Metamizole’s association with agranulocytosis is not new. The drug has been under scrutiny for decades due to its potential to directly affect bone marrow cells, leading to adverse reactions.Professor Navarra explained, “Over time, after some risks of adverse effects related to its use began to be reported, its consumption decreased. The drug can cause adverse effects by directly affecting bone marrow cells, and it is vital that the doctor is aware of the possibility of this adverse reaction.”
Despite its withdrawal in many countries, metamizole has remained in use in Italy, where it was perceived to carry a lower risk compared to other regions. However, recent findings have reignited concerns, prompting AIFA to issue its warning.
Safer Alternatives to Metamizole
For those seeking relief from pain and fever, there are safer alternatives. Professor Navarra highlighted ibuprofen as a viable option: “There are many other alternatives. We are talking about an antipyretic and anti-inflammatory drug, and on this front, we have drugs such as ibuprofen, which has the same therapeutic effect but does not present risks of this kind.”
Key Takeaways: What You Need to Know
To summarize the critical points:
| Aspect | Details |
|————————–|—————————————————————————–|
| Drug in Question | Metamizole (found in Novalgina and generics) |
| Serious Side Effect | Agranulocytosis (severe drop in white blood cells) |
| Symptoms | Fever,sore throat,chills (similar to flu) |
| Suggestion | Consult a doctor immediately if symptoms occur during metamizole therapy |
| Safer Alternatives | Ibuprofen and other antipyretics/anti-inflammatories |
A call for Vigilance
The AIFA’s warning serves as a reminder of the importance of being cautious with medications. While metamizole has been a go-to remedy for many, its potential risks cannot be ignored. As Professor Navarra aptly put it, “Avoiding unpleasant surprises must be the priority.”

Understanding the Risks of Metamizole: An Expert Interview on agranulocytosis and Safer Alternatives
In light of the recent warning issued by the Italian Medicines Agency (AIFA) regarding the potential dangers of metamizole, a widely used painkiller and fever reducer, concerns have grown about its association with agranulocytosis—a rare but severe side effect.To shed light on this critical issue, we sat down with Dr. Elena Rossi, a pharmacologist and expert in drug safety, to discuss the risks of metamizole, its impact on public health, and safer alternatives for managing pain and fever.
the risks of Metamizole: A Closer Look at Agranulocytosis
Senior Editor: Dr. Rossi, thank you for joining us. Let’s start with the basics. What exactly is metamizole,and why has it come under scrutiny?
Dr. rossi: Metamizole, also known by brand names like Novalgina, is a medication commonly used for its analgesic and antipyretic properties—meaning it relieves pain and reduces fever. Though, it has been linked to a rare but serious side effect called agranulocytosis. This condition involves a drastic reduction in granulocytes,a type of white blood cell essential for fighting infections. Without these cells, the body becomes highly vulnerable to bacterial and fungal infections, which can be life-threatening.
Senior Editor: How common is agranulocytosis,and what are the symptoms people should watch for?
Dr. rossi: Agranulocytosis is rare, occurring in about 1 in 10,000 to 1 in 100,000 users of metamizole. However, its severity makes it a significant concern.Symptoms often mimic those of the flu, including fever, sore throat, and chills. If someone taking metamizole experiences these symptoms, they should stop the medication immediately and consult their doctor. Early detection is crucial to prevent complications.
historical context: Why Has Metamizole Remained in Use?
Senior Editor: Metamizole has been withdrawn in many countries due to these risks. Why has it remained available in Italy?
Dr. Rossi: That’s a great question. In Italy, metamizole has been perceived as carrying a lower risk compared to other regions, partly due to its widespread use and historical acceptance. However, recent findings have reignited concerns, prompting AIFA to issue this warning.It’s crucial to note that while the drug is effective, its potential risks cannot be ignored, especially when safer alternatives are available.
safer Alternatives to Metamizole
Senior Editor: Speaking of alternatives,what options would you recommend for those seeking relief from pain and fever?
Dr. Rossi: There are several safer alternatives. Ibuprofen,for example,is an excellent option. It provides similar antipyretic and anti-inflammatory effects without the risk of agranulocytosis. Paracetamol (acetaminophen) is another widely used and generally safe choice for managing pain and fever. Both of these medications have well-established safety profiles and are effective for most people.
The Importance of Vigilance and Patient Awareness
Senior Editor: What advice would you give to patients currently using metamizole or considering it?
Dr. rossi: My advice is to always consult your healthcare provider before starting or continuing any medication. If you’re currently using metamizole, be vigilant for symptoms like fever, sore throat, or chills, and seek medical attention immediately if they occur. For those considering it, I would recommend discussing safer alternatives with your doctor. Avoiding unpleasant surprises must be the priority when it comes to medication safety.
Key Takeaways for Patients and Healthcare Providers
Senior Editor: To wrap up, could you summarize the key points our readers should take away from this discussion?
Dr. Rossi: Absolutely. First, metamizole is associated with a rare but serious risk of agranulocytosis, which can compromise the immune system. Second, symptoms of this condition can resemble the flu, so patients must be vigilant. Third,safer alternatives like ibuprofen and paracetamol are available and should be considered. always consult your doctor before making any changes to your medication regimen. Staying informed and cautious is the best way to protect your health.
Senior Editor: Thank you, Dr. Rossi, for sharing your expertise and helping us better understand this important issue.
Dr. Rossi: My pleasure. It’s crucial to raise awareness about medication safety, and I’m glad to contribute to this conversation.
