6. Contents of the pack and additional information

This medication contains the active ingredient alopurinol.

This medication works by reducing the speed of certain chemical reactions in the body to decrease the level of uric acid in the blood and urine.

High levels of uric acid can cause:

• Gout
• Formation of kidney stones or certain types of kidney problems

In gout, uric acid accumulates in joints and tendons in the form of crystals. These crystals cause an inflammatory reaction. The inflammation causes the skin around certain joints to swell, become sensitive, and hurt only when touched lightly. It may also be observed that intense pain occurs when moving the joint.

Alopurinol is used in adults:

• To reduce uric acid levels when diet is not sufficient
• For the treatment and prevention of the aforementioned complications, in which the body produces too much uric acid.

Do not take Alopurinol Stada:

• 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 this medication if:

• You have liver and kidney problems. Your doctor may administer a lower dose or ask you to take it less frequently. They may also monitor you more closely.
• You are currently experiencing a gout attack. Your doctor may also consider prescribing an appropriate analgesic or another gout medication (colchicine) during the first 4 weeks of treatment.
• You have thyroid problems.
• You have Chinese Han, Thai, or Korean ancestry.

Be especially careful with Alopurinol Stada:

Severe skin reactions(hypersensitivity syndrome, Stevens-Johnson syndrome, Toxic Epidermal Necrolysis) have been reported with the use of allopurinol. These may initially appear as red patches, bullet-shaped or circular (often with blisters in the middle) on the trunk of the body. The rash may also include ulcers in the mouth, throat, nose, genitals, and conjunctivitis (inflammation and redness of the eyes). These potentially fatal skin reactions usually precede symptoms similar to the flu (fever, headache, and body aches). The rash may progress to the formation of blisters and generalized peeling of the skin. If you develop a skin rash or these symptoms on your skin,stop taking allopurinol and consult your doctor immediately.

If you have experienced a severe skin reaction during treatment with allopurinol, you should not be treated with allopurinol again.

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

If you have cancer or Lesch-Nyhan syndromeThe amount of uric acid in your urine may increase. To prevent this, make sure to drink enough water to dilute your urine.

In case you have kidney stonesThe stones will become smaller and may enter your urinary tract, which could cause problems. The amount of urine you produce should be at least 2 liters per day to reduce the risk of kidney stone formation. Make sure to drink enough water.

Other medications and Alopurinol Stada

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication. This includes over-the-counter medications, including herbal medications. This is because allopurinol may affect the functioning of some medications. Some other medications may also affect the functioning of allopurinol.

Inform your doctor if you are taking any of the following medications:

• probencid, benzbromarone, sulfinpyrazone (gout medication)
• aspirin
• 6-mercaptopurine or azathioprine (cancer medications)
• ampicillin or amoxicillin (antibiotics): do not take allopurinol with ampicillin or amoxicillin as this may cause an increase in the frequency of skin rash. Use an alternative to ampicillin or amoxicillin when available.
• warfarin (blood-thinning medication)
• chlorpropamide (diabetes medication)
• theophylline (respiratory or cardiac problems medication)
• In combination with cytostatics (e.g. cyclophosphamide, doxorubicin, bleomycin, procarbazine, haloalkanes), hematological disorders occur more frequently than when these active principles are administered alone. Therefore, regular hematological controls should be performed.
• vidarabine (used to treat herpes or varicella)
• ciclosporin (immunosuppressive medication)
• phenytoin (epilepsy medication)
• didanosine (used to treat HIV infection)
• • aluminum hydroxide. If taken concomitantly, allopurinol may have a reduced effect, so it is advisable to leave a gap of at least 3 hours between the two medications. Regular hematological controls should be performed.
• furosemide and diuretics (medications to eliminate excess body fluid), such as thiazides
• ACE inhibitors (medications for heart problems or high blood pressure), especially if you have kidney problems or chronic kidney disease.
