1. What Allopurinol Nordic Drugs is and what it is used for

Allopurinol Nordic Drugs is a remedy for gout and high uric acid levels in the blood and is used especially in connection with a disease of the renal ducts (gout nephropathy) and stones in the urinary tract (urate stones). Allopurinol inhibits the formation of uric acid in the body and therefore prevents urate precipitation in tissues and the formation of urate stones and gravel in the urine.

Allopurinol Nordic Drugs are also used in so-called secondary gout that can occur in blood cancer ( leukemia ), in increasing the number of red blood cells ( polycythemia vera ), or in bone marrow tumor ( myeloma ). The drug can also be used for the preventive purpose against elevated uric acid levels that may occur during treatment for cancer with cytotoxic drugs and radiation therapy.

Allopurinol contained in Allopurinol Nordic Drugs may also be approved for the treatment of other conditions not mentioned in this leaflet. Ask your doctor, pharmacist, or another healthcare professional if you have any further questions, and always follow their instructions.

Warnings and cautions

Talk to your doctor before taking Allopurinol Nordic Drugs if you:

  • has impaired renal function. Your doctor may give you a lower dose or ask you to take the medicine less often than once a day. You will also be more closely monitored.

Xanthine is a precursor to uric acid. Allopurinol may in rare cases increase the concentration of xanthine in the body and cause xanthine deposits in the urinary tract. It is therefore important to drink plenty of fluids during treatment with Allopurinol Nordic Drugs to avoid urinary xanthine precipitation.

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Certain penicillins (ampicillin), certain agents that affect the immune system (azathioprine, cyclosporine, cyclophosphamide, mercaptopurine), certain anti-asthma drugs (theophylline) may affect or be affected by treatment with allopurinol. Anyone who is being treated with blood thinners at the same time, such as warfarin, should have their blood coagulation ability checked regularly.

The use of, for example, probenecid or high- dose salicylates may reduce the effect of Allopurinol Nordic Drugs, which should be assessed on a case-by-case basis.
