Severe skin reactions (hypersensitivity syndrome, Stevens-Johnson syndrome, toxic epidermal necrolysis) have been reported with the use of alopurinol. 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, body aches. The rash may progress to the formation of blisters and generalized skin peeling. These severe skin reactions may be more frequent in people of Chinese Han, Thai or Korean origin.Additionally, the risk of developing chronic renal insufficiency may increase in these patients. If you develop a skin rash or these symptoms on the skin, stop taking alopurinol and consult your doctor immediately.

The period of highest risk of appearance of severe skin reactions is during the first weeks of treatment.

If you have developed Stevens-Johnson syndrome or toxic epidermal necrolysis with the use of alopurinol, you should not use Alopurinol Teva again at any time.

Taking Alopurinol Teva with other medications

Inform your doctor or pharmacist if you are using or have recently used other medications, including those purchased without a prescription, especially the following: 6-mercaptopurine (for the treatment of certain types of cancer), azathioprine (to prevent rejection in transplants and the treatment of autoimmune diseases), arabinoside of adenine (vidarabine, for the treatment of viral infections), salicylates (aspirin, for the treatment of pain), uricosuric agents (probenecid, for the treatment of gout), chlorpropamide (for the treatment of diabetes), theophylline (for asthma), phenytoin (for epilepsy), ampicillin (antibiotic), amoxicillin (antibiotic), cyclophosphamide (for rheumatoid arthritis and the treatment of certain types of cancer), doxorubicin (for the treatment of certain types of lymphomas), bleomycin (for the treatment of certain types of cancer), procarbazine (for the treatment of certain types of cancer), mechlorethamine (for the treatment of certain types of cancer), cyclosporine (to prevent rejection in transplants), anticoagulant coumarins (to prevent the formation of blood clots) and didanosine (for the treatment of HIV) and captopril.

Administration of 6-mercaptopurine or azathioprine with alopurinol should be avoided. When 6-mercaptopurine or azathioprine are administered with alopurinol, the dose of 6-mercaptopurine or azathioprine should be reduced because its activity will be prolonged. This could increase the risk of severe blood disorders. In this case, your doctor will closely monitor your blood count during treatment.

Go to your doctor immediately if you notice any unexplained bruising, bleeding, fever or sore throat.

If you are taking aluminum hydroxide concomitantly, alopurinol may have a reduced effect, so it is advisable to leave a gap of at least 3 hours between taking both medications.

In the administration of alopurinol in combination with cytostatics (e.g. cyclophosphamide, doxorubicin, bleomycin, procarbazine, alkylating agents), blood disorders occur more frequently than when these active ingredients are administered alone.

Therefore, periodic hematological controls should be performed.
