NOLOTIL 575 mg HARD CAPSULES

2. What you need to know before taking Nolotil

Do not take Nolotil:

• If you have previously had a significant decrease in a type of white blood cell called granulocytes, which was caused by metamizole or other similar medicines called pyrazolones or pyrazolidines.
• If you have bone marrow problems or have a disorder that affects the way your blood cells are produced or function.

• If you have had previous allergic reactions or hematological reactions (decrease in white blood cells, red blood cells, or platelets in the blood) with medicines containing metamizole or other similar compounds, or allergic reactions to any of the other components of this medicine (listed in section 6).
• If you have had symptoms of asthma, rhinitis, or urticaria (red patches or hives on the skin that can cause itching) during treatment with other analgesics such as acetylsalicylic acid, paracetamol, or non-steroidal anti-inflammatory drugs, as you may also be sensitive to metamizole (the active substance of Nolotil).
  • If you have acute intermittent porphyria (a disorder of the metabolism of blood pigments that are part of hemoglobin).
  • If you have a genetic deficiency of glucose-6-phosphate dehydrogenase.
  • If you have had alterations in bone marrow function (blood cell formation); for example, during or after receiving antitumor chemotherapy (antineoplastic) or if you have had diseases related to blood cell formation.
  • If you are in the last three months of pregnancy.
  • If you have had severe skin reactions (such as Stevens-Johnson syndrome or toxic epidermal necrolysis) with previous use of Nolotil or another medicine that contained metamizole.

Warnings and Precautions

Consult your doctor or pharmacist before starting to take Nolotil.

Low White Blood Cell Count (Agranulocytosis).

Nolotil may cause agranulocytosis, a very low level of a type of white blood cell called granulocytes, which are important for fighting infections (see section 4). You should stop taking metamizole and contact a doctor immediately if you experience any of the following symptoms, as they may indicate possible agranulocytosis: chills, fever, sore throat, and painful sores in the mucous membranes (wet 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 count.

If you take metamizole for fever, some symptoms of agranulocytosis may go unnoticed. Similarly, symptoms may be masked if you are taking antibiotics.

Agranulocytosis can occur at any time during the use of Nolotil and even shortly after stopping metamizole.

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

Be especially careful:

• If you experience general discomfort, infection, persistent fever, sore throat, inflammation in the mouth, nose, or throat, lesions in the mouth or genital mucosa, bruising, 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, swelling of the face, decreased blood pressure, sudden onset of red patches on the skin, stop treatment and consult your doctor. These symptoms may be due to a severe allergic reaction called anaphylactic shock. This reaction is more likely if you have asthma or allergic disorders (atopy).
• If you have bronchial asthma (especially in the presence of nasal mucosa inflammation and nasal polyps), chronic urticaria, or if you are intolerant to dyes and/or preservatives or alcohol, as the risk of severe allergic reactions is higher.
• If you have low blood pressure, hypovolemia (decreased circulating blood volume or any other body fluid), dehydration, or unstable circulation, as the risk of a sudden drop in blood pressure is higher.
• If you have reduced kidney or liver function, as you may have difficulty eliminating the medicine.
• If you are an elderly patient, be especially alert to the appearance of any of the disorders described above, as they may occur more frequently.

Liver Problems:

Inflammation of the liver has been reported in patients taking metamizole, with symptoms developing within a few days to a few months after starting treatment.

Stop taking Nolotil and contact a doctor if you experience symptoms of liver problems, such as discomfort (nausea or vomiting), fever, fatigue, 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.

Do not take Nolotil if you have previously taken a medicine containing metamizole 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 metamizole treatment. Stop taking metamizole and seek medical attention immediately if you experience 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 Nolotil at any time (see section 4).

Taking Nolotil with Food, Drinks, and Alcohol

Together with alcohol, the effects of both can be enhanced.

Pregnancy, Breastfeeding, and Fertility

Pregnancy

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

During the last three months of pregnancy, you should not take Nolotil due to the increased risk of complications for the mother and the baby (bleeding, premature closure of a vital blood vessel for the fetus, called the ductus arteriosus, which closes naturally after birth).

Breastfeeding

Metamizole degradation products are excreted in breast milk in significant amounts, and it cannot be excluded that there is a risk for the breastfed infant. Therefore, repeated use of metamizole during breastfeeding should be avoided. If a single dose of metamizole is administered, mothers are recommended to express and discard breast milk for 48 hours after administration.

Driving and Using Machines

Although no adverse effects on concentration and reaction ability are expected, at the highest recommended doses, it should be taken into account that these abilities may be affected, and you should avoid using machines, driving vehicles, or engaging in other hazardous activities.

Taking Nolotil with Other Medicines

Tell your doctor or pharmacist if you are using or have recently used or may need to use any other medicine.

If administered together with cyclosporin (a medicine that prevents transplant rejection), it may reduce cyclosporin blood levels, and these should be regularly monitored.

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

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

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

If administered together with bupropion (a medicine used for the treatment of depression and/or to help stop smoking), efavirenz (a medicine used for the treatment of HIV/AIDS), methadone (a medicine used to treat opioid dependence), valproate (a medicine used to treat epilepsy or bipolar disorder), tacrolimus (a medicine used to prevent organ rejection in transplant patients), or sertraline (a medicine used to treat depression), it may reduce the blood levels of these medicines, and caution should be exercised.

Metamizole may modify the effect of antihypertensives (medicines that lower blood pressure) and diuretics (medicines that increase fluid elimination).

3. How to Take Nolotil

Follow the administration instructions of this medicine exactly as indicated by your doctor. If in doubt, consult your doctor or pharmacist again.

This medicine is for short-term use. Your doctor will indicate the duration of your treatment.

This medicine should be administered orally. The capsules should be swallowed whole, without chewing, with a little liquid.

The dose is determined based on the intensity of the pain or fever and the individual's sensitivity to treatment with Nolotil. The lowest necessary dose should always be selected to control pain and fever. Your doctor will indicate how to take Nolotil.

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 metamizole) as a single dose, which can be administered up to 6 times a day, at 4- to 6-hour intervals. The maximum daily dose is 3,450 mg (corresponding to 6 capsules).

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

Children and Adolescents Under 15 Years of Age

Nolotil should not be used in children under 15 years of age. Other presentations and doses of this medicine are available for younger children; consult your doctor or pharmacist.

Elderly Patients and Patients with Poor General Health or Renal Insufficiency

The dose should be reduced in elderly patients, debilitated patients, and those with reduced renal function, as the elimination of metamizole degradation products may be delayed.

Patients with Renal or Hepatic Insufficiency

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

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

If You Take More Nolotil Than You Should

Nausea, vomiting, abdominal pain, deterioration of kidney function, and, in rarer cases, dizziness, drowsiness, coma, convulsions, decreased blood pressure, or even shock and increased heart rate (tachycardia) may occur.

After administration of very high doses of metamizole, a red coloration of the urine may occur, which disappears when treatment is stopped.

If you have taken more medicine than you should, consult your doctor or pharmacist, or the Toxicological Information Service, telephone 91 562 04 20.

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 metamizole is dialyzable.

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

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

If You Forget to Take Nolotil

Do not take a double dose to make up for forgotten doses.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
