Warnings and precautions

Consult your doctor or pharmacist before starting Metamizol Kern Pharma 575 mg.

Low white blood cell count (agranulocytosis).

Metamizol Kern Pharma may cause agranulocytosis, a very low level of a type of white blood cells called granulocytes, which are important for fighting infections (see section 4). You should stop taking metamizol and contact a doctor immediately if you experience the following symptoms, as they may indicate a possible agranulocytosis: chills, fever, sore throat, and painful sores in the mucous membranes (moist surfaces of the body) especially in the mouth, nose, and throat or in the genital or anal area. Your doctor will perform laboratory tests to check your blood cell levels.

If you take metamizol for fever, some symptoms of agranulocytosis may be overlooked. Similarly, symptoms may be masked if you are taking antibiotics.

Agranulocytosis can occur at any time during the use of Metamizol Kern Pharma and even after stopping metamizol.

You may develop agranulocytosis even if you have used metamizol without problems in the past.

Liver problems

Inflammation of the liver has been reported in patients taking metamizol with symptoms that develop within a few days to several months after starting treatment.

Stop using Metamizol Kern Pharma 575 mg and contact a doctor if you experience symptoms of liver problems, such as nausea or vomiting, fever, feeling tired, loss of appetite, dark urine, light-colored stools, yellowing of the skin or the white part of the eyes, itching, rash, or upper abdominal pain. Your doctor will check your liver function.

You should not take Metamizol Kern Pharma 575 mg if you have previously taken a medication containing metamizol and had liver problems.

Severe skin reactions

Severe skin reactions, such as Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug reaction with eosinophilia and systemic symptoms (DRESS), have been reported in association with the use of metamizol. Stop taking metamizol and seek medical attention immediately if you observe any of the symptoms related to these severe skin reactions described in section 4.

If you have ever had severe skin reactions, you should not restart treatment with [brand name] at any time (see section 4).

Be careful:

• If you experience general discomfort, infection, persistent fever, sore throat, inflammation in the mouth, nose, or throat, lesions in the mucous membranes of the mouth or genitals, bruises, bleeding, or paleness, you should stop treatment and consult your doctor immediately. These disorders may be due to a decrease in the number of white blood cells in the blood (agranulocytosis), platelets (thrombocytopenia), or a failure in the production of all blood cells (aplastic anemia).

• If you experience dizziness, difficulty breathing, rhinitis, facial swelling, decreased blood pressure, sudden red patches on the skin, stop treatment and consult your doctor. These symptoms may be due to a severe allergic reaction to metamizol called anaphylactic shock. This reaction is more likely if you have asthma or allergic disorders (atopy).

• If you have bronchial asthma (especially with nasal mucosa inflammation and nasal polyps), chronic urticaria, or if you are intolerant to dyes and/or preservatives or to alcohol, as the risk of possible severe allergic reactions is higher.
• If you have low blood pressure or havehypovolemia (decrease in circulating blood volume or any other body fluid), dehydration, orunstable circulation, as the risk of a sudden drop in blood pressure is higher.
• If a rash appears on the skin that progresses to the formation of blisters or lesions in the mucous membranes, you should interrupt treatment and see a doctor, as this may be due to the appearance of severe skin disorders (Stevens-Johnson syndrome or toxic epidermal necrolysis). In these cases, you should not receive metamizol-containing medications againIf you have decreased liver or kidney functionas you may eliminate the medicationwithgreater difficulty.
• If you are an elderly patient, be especially aware of the appearance of any of the disorders described above, as they may appear more frequently.

Use of metamizol with other medications

Inform your doctor or pharmacist if you are using or have used recentlyor may need to use any other medication.

If administered together with ciclosporin (a medication that prevents transplant rejection), it may reduce the levels of ciclosporin in the blood and therefore these should be measured regularly.

If administered together with chlorpromazine (a medication for the treatment of psychoses), it may cause a decrease in body temperature.

If administered together with methotrexate or other medications for the treatment of tumors (antineoplastic), it may potentiate the toxic effects in the blood of antineoplastic medications, especially in elderly patients.

If administered together with acetylsalicylic acid, it may reduce the effect of acetylsalicylic acid to decrease platelet aggregation (antiplaquetary) and therefore it should be used with caution in patients taking it to protect the heart (cardioprotector).

If administered together with bupropion,a medication used for the treatment of depression and/or to help quit smoking,it may reduce the levels of bupropion in the blood, and therefore it should be used with caution.

Metamizol may modify the effect of anti-hypertensive medications (medications that reduce blood pressure) and diuretics (medications that increase the elimination of liquids).

If administered together with:

-efavirenz, a medication used for the treatment of HIV/AIDS

-metadona, a medication used to treat dependence on illicit drugs (designated opioids)

-valproato, a medication used to treat epilepsy or bipolar disorder

-tacrolimus, a medication used to prevent transplant rejection

-sertralina, a medication used to treat depression

Taking Metamizol Kern Pharma 575 mg with food, drinks, and alcohol

Together with alcohol, the effects of both may be potentiated.

Pregnancy, breastfeeding, and fertility

Pregnancy

The available data on the use of metamizol during the first three months of pregnancy are limited, but do not indicate harmful effects on the embryo. In selected cases where there are no other treatment options, single doses of metamizol during the first and second trimesters may be acceptable after consulting with your doctor or pharmacist and then evaluating the benefits and risks of using metamizol. However, in general, the use of metamizol during the first and second trimesters is not recommended.

During the last three months of pregnancy, you should not take METAMIZOL KERN PHARMA 575 mg due to the increased risk of complications for the mother and the baby (bleeding, premature closure of a major vessel for the fetus, called the ductus arteriosus, which normally closes naturally after birth).

Breastfeeding

Metamizol degradation products are excreted in breast milk in significant amounts, and it cannot be ruled out that there may be a risk to the infant. Therefore, repeated use of metamizol during breastfeeding should be avoided. In the event of a single dose of metamizol, mothers are recommended to express and discard breast milk during the 48 hours following its administration.

Driving and operating machines

Although no adverse effects on concentration and reaction capacity are expected, at higher doses within the recommended range, you should be aware that these capacities may be affected and you should avoid operating machines, driving vehicles, or other hazardous activities. This is especially applicable when alcohol has been consumed.

Follow exactly the administration instructions of this medication as indicated by your doctor. In case of doubt, consult your doctor or pharmacist again.

This medication is for short-term use. Your doctor will inform you of the duration of your treatment.

The dose is established based on the intensity of the pain or fever and the sensitivity of each person to treatment with metamizol. Always select the lowest necessary dose to control pain and fever. Your doctor will inform you how to take Metamizol Kern Pharma.

This medication must be administered orally.

Adults and adolescents 15 years of age or older

Adults and adolescents 15 years of age or older (who weigh more than 53 kg) can take 1 capsule (575 mg of metamizol) in a single dose, which can be administered up to 6 times a day, in intervals of 4 to 6 hours. The maximum daily dose is 3,450 mg (corresponding to 6 capsules).

The effect of the medication usually appears between 30 and 60 minutes after oral administration.

Metamizol Kern Pharma should not be used in children under 15 years of age. For smaller children, other presentations and doses of this medication are available; consult your doctor or pharmacist.

The capsules should be swallowed whole, without chewing, with the help of a little liquid.

Older adults and patients with poor general health or renal insufficiency

The dose should be reduced in older adults, in debilitated patients, and in those with decreased renal function, as the elimination of metamizol degradation products may be delayed.

Patients with renal or hepatic insufficiency

Since in cases of renal or hepatic insufficiency the elimination rate decreases, high repeated doses should be avoided. Only in short-term treatments, a dose reduction is not necessary. There is no experience with prolonged treatments.

If the pain persists or worsens, consult a doctor to investigate the cause of the symptoms.

If you take more Metamizol Kern Pharma 575 mg than you should

Nausea, vomiting, abdominal pain, renal function deterioration, and in very rare cases, dizziness, somnolence, coma, seizures, and decreased blood pressure or even shock and increased heart rate (tachycardia) may appear.

After administration of very high doses of metamizol, a reddish discoloration of the urine may occur, which disappears when the treatment is suspended.

Information for the doctor:

No specific antidote is known. After oral overdose, gastric lavage and forced vomiting may be performed. Forced diuresis or dialysis may be considered, as metamizol is dialyzable.

In case of severe allergic reactions, additional emergency measures should be applied, such as placing the patient on their side, maintaining airways free of obstruction, or administering oxygen. Pharmacological emergency measures include administering adrenaline, fluid therapy, and glucocorticoids.

Careful monitoring of vital functions, as well as taking general necessary measures, is recommended.
