Are you on Azathioprine for a Kidney Transplant or RA (Rheumatoid Arthritis)? I assume RA since you were taking the anti-inflamm drug before.
Azathioprine can cause an increase in cancer risk when used long-term. This particular risk increases in patients with a prior history of treatment with other powerful immunosuppressants, such as Cytoxan, Leukeran, and Alkeran. It also increases the risk of serious infections. Azathioprine can impair fertility by reducing sperm counts in males. Because azathioprine's toxicity increases when taken with the gout medication allopurinol (Zyloprim), its dose is reduced with simultaneous use. Severely low white blood counts can occur when taken with other drugs that can affect the bone marrow or with ACE-inhibitor class drugs used to treat elevated blood pressure, such as Accupril and Vasotec.
The most common serious side effects of azathioprine involve the blood elements and gastrointestinal system. Azathioprine can cause serious lowering of the white blood cell count, resulting in an increased risk of infections. This can reverse when the dose is reduced or temporarily discontinued. Azathioprine can cause nausea, vomiting, and loss of appetite, which can resolve when the dose is reduced or divided through the day. Azathioprine can also cause liver toxicity (in less than 1% of rheumatoid arthritis patients). All patients taking azathioprine require regular blood testing for blood counts and liver function tests for monitoring. Other side effects encountered less frequently include fatigue, hair loss, joint pains, and diarrhea.
I certainly would not be using any AAS while taking Azatioprine. I feel the combination of the two could cause a severe imbalance in your system.
