Read this package leaflet carefully before you start taking this medicine because it contains important information for you.

• Keep this package leaflet, as you may need to read it again.
• If you have any questions, consult your doctor or pharmacist.
• This medicine has been prescribed for you only, and you must not give it to others even if they have the same symptoms as you, as it may harm them.
• If you experience any side effects, consult your doctor or pharmacist, even if they are not listed in this package leaflet. See section 4.

• Alopurinol Aurovitas belongs to a group of medications called enzyme inhibitors, which act by controlling the speed at which a certain chemical process occurs in the body.
• Alopurinol tablets are used long-term to prevent the occurrence of gout and other situations caused by excess uric acid in the body, including kidney stones and other types of kidney diseases.

Do not take Alopurinol Aurovitas:

• If you are allergic to allopurinol or any of the other components of this medication (listed in section 6).

Warnings and precautions

Inform your doctor or pharmacist before taking allopurinol if:

• You are of Chinese Han, African or Indian descent.
• You have liver and kidney problems. Your doctor may give you a lower dose or ask you to take it less frequently each day. They may also monitor you more closely.
• You have heart problems or high blood pressure and are taking diuretics and/or medications called ACE inhibitors.
• You are currently experiencing a gout attack.
• You have thyroid problems.

If you are unsure whether any of the following situations affect you, inform your doctor or pharmacist before taking allopurinol.

Be especially careful with allopurinol:

• Severe skin reactions (hypersensitivity syndrome, Stevens-Johnson syndrome, toxic epidermal necrolysis) have been reported with the use of allopurinol. The rash often includes ulcers in the mouth, throat, nose, genitals, and conjunctivitis (inflammation and redness of the eyes). These severe skin reactions are often preceded by flu-like symptoms such as fever, headache, and body aches. The rash may progress to the formation of blisters and generalized skin peeling.

These severe skin reactions may be more common in people of Chinese Han, Thai, or Korean descent. Additionally, the risk of chronic kidney disease may increase in these patients.

If you develop a skin rash or these symptoms on your skin, stop taking allopurinol and consult your doctor immediately.

• If you have cancer or Lesch-Nyhan syndrome, the amount of uric acid in your urine may increase. To prevent this, make sure to drink enough to dilute your urine.
• If you have kidney stones, the stones will become smaller and may enter your urinary tract.

Children

Use in children is rarely indicated, except for some types of cancer (especially leukemia) and certain enzymatic disorders such as Lesch-Nyhan syndrome.

Taking Alopurinol Aurovitas with other medications

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication:

• 6-mercaptopurine (used in the treatment of blood cancer).
• Azathioprine, cyclosporine (used to suppress the immune system). Note that cyclosporine side effects may occur more frequently.
• Vidarabine (used in the treatment of herpes). Note that vidarabine side effects may occur more frequently. Be especially cautious if this happens.
• Salicylates (used to reduce pain, fever, or inflammation; e.g. Aspirin).
• Probenecid (used to treat gout).
• Chlorpropamide (used to treat diabetes). You may need to reduce the dose of chlorpropamide, especially in patients with reduced renal function.
• Warfarin, phenprocoumon, acenocoumarol (anticoagulants). Your doctor will monitor your hematological controls more frequently, and if necessary, reduce the dose of these medications.
• Phenytoin (used to treat epilepsy).
• Theophylline (used to treat asthma and other respiratory diseases). Your doctor will measure theophylline levels in your blood, especially when starting treatment with allopurinol, or following any dose changes.
• Ampicillin or amoxicillin (used to treat bacterial infections). When possible, patients should receive other antibiotics as it is more likely that allergic reactions will occur.
• Medications to treat aggressive tumors such as:

• Cyclophosphamide
• Doxorubicin
• Bleomycin
• Procarbazine
• Mecloretamine

Your doctor will monitor your hematological controls frequently.

• Didanosine (used to treat HIV infection).
• ACE inhibitors (e.g. captopril) or diuretics (used to treat high blood pressure). The risk of skin reactions may increase, especially in patients with chronic kidney function limitations.

If you are taking aluminum hydroxide concomitantly, allopurinol may be attenuated, so it is advisable to leave a gap of at least 3 hours between the two medications.

When administering allopurinol in combination with cytostatics (e.g. cyclophosphamide, doxorubicin, bleomycin, procarbazine, alkylating agents), hematological disorders occur more frequently than when these active principles are administered alone.

Therefore, periodic hematological controls should be performed.

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other type of medication, including over-the-counter medications, herbal medications, as allopurinol may affect how some medications work. Other medications may also affect the functioning of allopurinol.

It is not recommended to use allopurinol during breastfeeding. Do not take this medication if you are pregnant or breastfeeding unless your doctor recommends it.

Generally, your doctor will start treatment with alopurinol at a low dose (e.g., 100 mg/day) to reduce the risk of possible adverse effects. Your dose will be increased if necessary.

The recommended dose is:

Adults (including elderly patients)

Starting dose: 100 - 300 mg/day.

When starting treatment, your doctor may also prescribe an anti-inflammatory medication or colchicine for a month or more to prevent gouty arthritis attacks.

Your alopurinol dose may be adjusted depending on the severity of the disease.

The maintenance dose is:

1. 100 - 200 mg/day in mild alterations
2. 300 - 600 mg/day in moderate alterations
3. 700- 900 mg/day in severe alterations

Your doctor may also modify your dose if you have reduced renal and hepatic function, especially if you are an elderly patient.

If the daily dose exceeds 300 mg/day and you are experiencing gastrointestinal adverse effects such as nausea or vomiting (see section 4), your doctor may prescribe alopurinol in divided doses to reduce these effects.

If you have severe kidney problems

• They may ask you to take less than 100 mg per day,
• or take 100 mg at longer intervals than a day.

If you are on dialysis 2 or 3 times a week, your doctor may prescribe a dose of 300-400 mg immediately after each dialysis session.

Children (under 15 years)

• 100-400 mg/day.
• Treatment may be started with an anti-inflammatory medication or colchicine. The dose may be adjusted if you have reduced renal or hepatic function, or divided to reduce gastrointestinal effects, as in the case of adults.

If you take more Alopurinol Aurovitas than you should
