1. What is Milurit and what is it used for

The active substance of Milurit tablets is allopurinol. Allopurinol belongs to a group of medicines called enzyme inhibitors. These substances are effective in controlling the rate of certain changes occurring in the body.
Milurit is used long-term to prevent gout and may be used in other conditions associated with an excess of uric acid in the body, such as kidney stones and other kidney diseases, and 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 severe skin reactions occur during treatment with Milurit, hypersensitivity syndrome, Stevens-Johnson syndrome, or toxic epidermal necrolysis, you should not restart treatment with Milurit.

You should not restart treatment with Milurit.

In the early stages of treatment with Milurit, you may expect an acute gout attack. Therefore, your 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, your 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 plenty of fluids to 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.
Salicylates (used to reduce pain, fever, or inflammation, e.g., acetylsalicylic acid)
Theophylline, a medicine used in case of breathing problems. Your 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. You should exercise special caution 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, you should regularly undergo blood morphology tests.
If you are also taking aluminum hydroxide, allopurinol may have a weaker effect.
You should maintain an interval of at least 3 hours 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, you should reduce the dose of 6-mercaptopurine or azathioprine, as their effect will be prolonged. This may increase the risk of serious blood disorders. In such cases, your doctor will closely monitor your blood cell count during treatment.

• 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. Your doctor will monitor your 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 your 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. It is not recommended to use allopurinol 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 as directed by your doctor. If you have any doubts, 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 you experience gastrointestinal side effects such as nausea and vomiting (see section 4), your doctor may prescribe allopurinol in divided doses.
Dosing should always be determined individually by your doctor.

Recommended doses

Adults

Your doctor will usually start treatment with a small 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 it is necessary to determine the dose in mg/kg of body weight, a dose of 2 to 10 mg/kg of body weight per day should be used.
In the early stages of treatment, your 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)

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

If the patient has severe kidney disease

The patient may be advised to take a dose smaller than 100 mg per day or 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 immediately 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 before starting cytotoxic therapy, elevated uric acid levels should be normalized. It is essential 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 treatment with a small dose (e.g., 50 mg/day) after careful consideration of the risks. Then, you can gradually increase the dose, 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).

Overdose of Milurit

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

Missing a dose of Milurit

In case you miss a dose of Milurit, you should take it as soon as you remember. However, if it is almost time for your 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 directed by your doctor.

Stopping treatment with Milurit

The duration of treatment is determined by your 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 your doctor or pharmacist.
