Azapress Tablets contain the active ingredient Azathioprine which belongs to a group of medicines called immunosuppressants.

These include hepatitis (liver disease), rheumatoid arthritis, a condition called systemic lupus erythematosus(SLE), various blood and bleeding disorders and skin disorders.

•    You have been given Azathioprine before and had an allergic reaction

•    You have had an allergic reaction before to 6-mercaptopurine (6-MP) as you are more likely to be hypersensitive to Azathioprine.

Warnings and precautions

Talk to your doctor or pharmacist or nurse before taking Azapress Tablets if:

•    You have the inherited deficiency of the enzyme thiopurine methyltransferase (TPMT) or Lesch-Nyhan Syndrome (hypoxanthine-guanine-phosphoribosyltransferase deficiency)

•    You have kidney or liver disease.

Since many ofthe effects of Azathioprine cause changes in the blood, your doctor will probably want to take regular blood samples whilst you are taking this medicine to look out for any such changes.

Whilst undergoing treatment with Azathioprine, avoid excessive exposure to the sun. In addition, examine your skin regularly for any skin reactions or lumps. Ifyou experience any changes in your skin or develop any lumps (especially if you have had an organ transplant) tell your doctor immediately.

You should contact your doctor immediately if you notice any evidence ofinfection, unexpected bruising or bleeding as this may indicate a serious blood disorder (bone marrow depression).
