1. What is Milurit and what is it used for

The active substance of Milurit is allopurinol. Allopurinol belongs to a group of medicines called enzyme inhibitors. These substances are effective in controlling the rate of certain changes in the body.
Milurit is used long-term to prevent gout and may be used in other conditions related to an excess of uric acid in the body, such as kidney stones and other kidney diseases, as well as when the patient is receiving treatment for cancer or has enzyme function disorders.

2. Important information before taking Milurit

When not to take Milurit

• If the patient is allergic to allopurinol or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Before starting treatment with Milurit, you should discuss it with your doctor.
Special caution and close medical supervision may be necessary:

• If the patient belongs to the Han Chinese ethnic group or is of Thai or Korean origin.
• If the patient has liver or kidney disease. The doctor may recommend taking a smaller dose or taking the medicine less frequently than daily. The doctor will also monitor the patient more closely.
• If the patient has heart disease or high blood pressure and is taking diuretics and/or blood pressure-lowering medicines called ACE inhibitors.
• If the patient is currently experiencing a gout attack.
• If the patient or their close relative has hemochromatosis (a rare disease characterized by abnormally high iron absorption from the digestive tract, leading to excessive iron storage, especially in the liver).
• If the patient has thyroid disease.
• If the patient is being treated with azathioprine (a medicine used to weaken the immune response - immunosuppressive), mercaptopurine (a medicine used in leukemia).

In case of doubt as to whether any of the above situations apply, you should consult a doctor or pharmacist.
Severe skin reactions (hypersensitivity syndrome, Stevens-Johnson syndrome, toxic epidermal necrolysis) have been reported during treatment with allopurinol.
Often, the rash can involve ulcers of the mouth, throat, nose, genitals, and conjunctivitis (redness and swelling of the eyes). These potentially life-threatening severe skin reactions are often preceded by flu-like symptoms such as fever, headache, and body aches.
The rash may progress to generalized blisters and skin peeling.
These severe skin reactions may occur more frequently in people of Chinese, Thai, or Korean origin. Chronic kidney disease may also increase the risk in these patients.

In case of a rash or skin symptoms, you should stop taking Milurit, seek medical attention immediately, and inform your doctor that you are taking this medicine. If the patient experiences severe skin reactions, hypersensitivity syndrome, Stevens-Johnson syndrome, or toxic epidermal necrolysis while taking Milurit, they should not restart treatment with Milurit.

Do not restart treatment with Milurit.
Early in the treatment with Milurit, an acute gout attack can be expected. Therefore, the doctor may recommend prophylactic use of an appropriate anti-inflammatory medicine or colchicine for at least a month.
To monitor the safety and efficacy of treatment with Milurit, the doctor may order one or more laboratory tests. You should have these tests done and show the results to your doctor.
If the patient has been diagnosed with cancer or Lesch-Nyhan syndrome, the amount of uric acid in the urine may increase. To prevent this, you should drink enough fluids to properly dilute the urine.
If the patient has kidney stones, the stones in the kidneys will decrease in size during treatment and may move into the urinary tract.

Children and adolescents

Children and adolescents under 15 years of age should not take Milurit, except in cases of certain cancers (especially leukemia) or in the treatment of certain enzyme disorders, such as Lesch-Nyhan syndrome.

Milurit and other medicines

You should tell your doctor about any medicines you are currently taking or have recently taken, as well as any medicines you plan to take.
The following medicines are of particular importance:

• salicylates (used to reduce pain, fever, or inflammation, e.g., acetylsalicylic acid),
• theophylline, a medicine used in case of breathing problems. The doctor may order theophylline blood level tests, especially at the start of treatment with Milurit or modify its dose.
• medicines used to treat epilepsy (phenytoin),
• ampicillin or amoxicillin (used in bacterial infections). Because allergic reactions are more common, patients should receive other antibiotics if possible.
• didanosine, used in the treatment of HIV infection,
• vidarabine, used in the treatment of viral infections. Note: vidarabine side effects may occur more frequently. Particular caution is advised in case of their occurrence.
• blood disorders occur more frequently when allopurinol is taken with cytostatics (e.g., cyclophosphamide, doxorubicin, bleomycin, procarbazine, alkyl halides) than when these active substances are taken alone. Therefore, regular blood morphology tests should be performed.
• if aluminum hydroxide is taken at the same time, allopurinol may have a weaker effect. An interval of at least 3 hours should be maintained between taking both medicines.
• medicines used to weaken the immune response (immunosuppressive medicines), such as cyclosporine (cyclosporine side effects may occur more frequently),
• azathioprine (used to suppress the immune system) and 6-mercaptopurine (used in the treatment of blood cancer). You should avoid taking 6-mercaptopurine or azathioprine with allopurinol. When taking 6-mercaptopurine or azathioprine with Milurit, the dose of 6-mercaptopurine or azathioprine should be reduced, as their effect will be prolonged. This may increase the risk of serious blood disorders. In such cases, the doctor will closely monitor the patient's blood cell count during treatment. You should seek medical attention immediately if you notice any unexplained bruising, bleeding, fever, or sore throat.
• medicines used to treat diabetes (chlorpropamide). The dose of chlorpropamide may need to be reduced, especially in patients with kidney function disorders.
• medicines used to treat heart disease or high blood pressure, such as ACE inhibitors (e.g., captopril, ramipril) or diuretics (especially thiazide diuretics or furosemide)
• medicines used to thin the blood (anticoagulants), such as warfarin, phenprocoumon, and acenocoumarol. The doctor will monitor blood clotting parameters more frequently and, if necessary, reduce the dose of these medicines.
• other medicines used to treat gout (probenecid).

You should tell your doctor or pharmacist about all medicines you are currently taking or have recently taken, as well as any medicines you plan to take. This includes medicines sold without a prescription, including herbal medicines. This is necessary because Milurit may affect the action of other medicines. Other medicines may also affect the action of Milurit.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, you should consult a doctor or pharmacist before taking this medicine.
Pregnancy
The safety of using Milurit during pregnancy is not well documented.
Milurit should only be used during pregnancy if there is no safer alternative and the disease itself poses a risk to the mother or the unborn child.
Breastfeeding
Allopurinol is excreted in the breast milk of nursing mothers. Allopurinol is not recommended during breastfeeding.

Driving and using machines

Drowsiness, dizziness, or coordination disorders may occur. If such symptoms occur, you should not drive or operate machinery.

Milurit contains sodium

This medicine contains less than 1 mmol of sodium (23 mg) per tablet, which is essentially "sodium-free".

3. How to take Milurit

This medicine should always be taken exactly as prescribed by your doctor. If you are unsure, you should consult your doctor or pharmacist.
Milurit should be taken once a day after a meal. As long as you are taking this medicine, you should drink plenty of fluids (2-3 liters per day). If the daily dose exceeds 300 mg and the patient experiences gastrointestinal side effects such as nausea and vomiting (see section 4), the doctor may prescribe allopurinol in divided doses to reduce these effects.
Dosing should always be determined individually by the doctor.

Recommended doses

Adults

The doctor usually starts treatment with a low dose of allopurinol (e.g., 100 mg/day) to reduce the risk of side effects. If necessary, the dose will be increased.
Recommended maintenance doses are:
100 to 200 mg per day in mild conditions, 300 to 600 mg per day in moderate conditions, and 700 to 900 mg per day in severe conditions.
If the dose needs to be determined in mg/kg of body weight, a dose of 2 to 10 mg/kg of body weight per day should be used.
Early in the treatment, the doctor may prescribe an anti-inflammatory medicine or colchicine to be taken for at least a month to prevent gout attacks.

Use in children and adolescents (under 15 years of age)

In children under 15 years of age, Milurit is used in doses of 10 to 20 mg/kg of body weight per day, up to a maximum dose of 400 mg per day in 3 divided doses. The use of Milurit in children is rarely indicated, except in cases of cancer (especially leukemia) and certain enzyme disorders, such as Lesch-Nyhan syndrome.

Elderly patients (over 65 years of age)

The doctor will recommend the smallest dose of Milurit that will best control the symptoms.

If the patient has severe kidney disease

• the patient may be advised to take a dose smaller than 100 mg per day
• or advised to take a dose of 100 mg at intervals longer than once a day.

If the patient is dialyzed 2 or 3 times a week, the doctor may recommend a dose of 300 or 400 mg to be taken after dialysis.
In case of kidney disease, the doctor may monitor kidney function, especially if the patient is also taking diuretics (especially thiazide diuretics).

If the patient has liver disease

The doctor may recommend taking smaller doses. Periodic liver function tests may be necessary, especially at the start of treatment.
Treatment of conditions with increased uric acid turnover(e.g., cancer, enzyme function disorders)
It is recommended that the increased uric acid level be corrected before starting cytotoxic therapy. It is important to ensure adequate fluid intake.

Skin reactions

In case of skin reactions, you should immediatelystop taking allopurinol. After mild skin reactions have resolved, you can restart taking the medicine in a small dose (e.g., 50 mg/day) after careful consideration of the risks. Then, the dose can be gradually increased while monitoring for skin reactions and other potential side effects. In case of a rash relapse, you should permanentlydiscontinue the medicine, considering the possibility of severe skin reactions (see section 4 Possible side effects).

Taking a higher dose of Milurit than recommended

In case of taking a higher dose of Milurit than recommended, or if you think a child has swallowed the tablets, you should contact a doctor or immediately go to the hospital emergency department. You should bring this leaflet, the remaining tablets, and the packaging of the medicine so that the doctor knows which tablets were taken.
The most common symptoms of overdose are nausea, vomiting, diarrhea, or dizziness.
Until medical help is provided, you should ensure a large intake of fluids.

Missing a dose of Milurit

In case of missing a dose, you should take it as soon as you remember. However, if it is almost time for the next dose, you should skip the missed dose. You should not take a double dose to make up for the missed dose. You should continue treatment as prescribed by your doctor.

Stopping treatment with Milurit

The duration of treatment is determined by the doctor.
You should not stop taking Milurit without first consulting your doctor, unless you experience allergic reactions or other severe side effects (see section 4).
In case of any further doubts about the use of this medicine, you should consult a doctor or pharmacist.
