What Allopurinol Takeda is and what it is used for

Allopurinol Takeda inhibits the formation of uric acid and thus lowers the level of urate (uric acid salt) in the body. In this way, the formation of urate stones and gravel in the urine, as well as urate crystallization in joints and tissues, are prevented.

Allopurinol Takeda is used for gout and conditions with elevated uric acid levels in the blood.

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

2. What you need to know before you use Allopurinol Takeda

Do not use Allopurinol Takeda

-If you are allergic to allopurinol or any of the other ingredients of this medicine (listed in section 6).

Warnings and cautions

Talk to your doctor or pharmacist before using Allopurinol Takeda

  • if you have impaired liver or kidney function
  • if you have an ongoing gout attack
  • if you are of Chinese or Korean descent
  • if you have thyroid problems.

During treatment with Allopurinol Takeda:

– Severe skin rash (hypersensitivity syndrome, Stevens-Johnson syndrome, toxic epidermal necrolysis ) has been reported with the use of allopurinol. The rash can often include sores in the mouth, throat, nose, genitals, and conjunctivitis (red and swollen eyes). These severe skin rashes are often preceded by flu-like symptoms such as fever, headache, and body aches. The rash can develop into extensive blistering and flaking of the skin.

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

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

– If you have a serious illness such as cancer or Lesch-Nyhan syndrome, xanthine, a precursor to uric acid, can accumulate in the body. To avoid the accumulation of xanthine in the urinary tract, it is therefore important to drink enough.

– If you have kidney stones, the kidney stones can become smaller and get into the urinary tract, which can cause problems.

Other medicines and Allopurinol Takeda

The effect of the treatment can be affected if Allopurinol Takeda is taken at the same time as other medicines. Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines:

  • azathioprine (used to suppress the immune system)
  • chemotherapy (used to treat cancer). When allopurinol and cytostatics are used concomitantly (eg cyclophosphamide, doxorubicin, bleomycin, procarbazine, alkyl halides), blood dyscrasias occur more frequently than when these active substances are used separately. Blood levels should therefore be checked regularly.
  • mercaptopurine (used to treat blood cancer ( leukemia )
  • cyclosporine (used to suppress the immune system, for example after organ transplantation and in rheumatism)
  • didanosine (used to treat HIV – infection s)
  • theophylline (used to treat asthma )
  • vidarabine (used to treat viral infections)
  • phenytoin (used in epilepsy )
  • blood thinners such as warfarin
  • antacids (for heartburn and acid reflux)
  • probenecid (used to treat gout )
  • chloropropamide (used to treat diabetes )
  • diuretics, ACE inhibitors (medicines used to treat heart problems or high blood pressure )
  • salicylates in high doses (used for pain relief, to reduce swelling, and to lower body temperature).
  • ampicillin or amoxicillin (medicines used to treat infections ). The risk of allergic rash may increase with concomitant treatment with Allopurinol Takeda.
  • aluminum hydroxide (used to neutralize stomach acid). If aluminum hydroxide is taken at the same time, the effect of allopurinol may be reduced. There should be an interval of at least 3 hours between taking these two drugs.

Pregnancy and breastfeeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before using this medicine. Limited experience of use during pregnancy.

Driving and using machines

Drowsiness, dizziness, and inability to coordinate movements have occurred during treatment with Allopurinol Takeda. This should be taken into account when sharpened attention is required, e.g. when driving and handling machines. You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects. Descriptions of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. If you are not sure, talk to your doctor or pharmacist.
