Hematologic toxicities are dose-related and may be more severe in renal transplant patients whose homograft is undergoing rejection. It is suggested that patients on Azathioprine have complete blood counts, including platelet counts, weekly during the first month, twice monthly for the second and third months of treatment, then monthly or more frequently if dosage alterations or other therapy changes are necessary.

Use with Angiotensin-Converting Enzyme Inhibitors The use of angiotensin -converting enzyme inhibitors to control hypertension in patients on azathioprine has been reported to induce anemia and severe leukopenia. Use with ribavirin The use of ribavirin for hepatitis C in patients receiving azathioprine has been reported to induce severe pancytopenia and may increase the risk of azathioprine-related myelotoxicity.
Inosine monophosphate dehydrogenase IMDH is required for one of the metabolic pathways of azathioprine. Ribavirin is known to inhibit IMDH, thereby leading to accumulation of an azathioprine metabolite, 6-methylthioionosine monophosphate 6MTITP , which is associated with myelotoxicity neutropenia , thrombocytopenia, and anemia.
