{"Azathioprine can be affected by a patient's TPMT and NUDT15 phenotype. This patient is predicted to be possible TPMT intermediate metabolizer and is at risk for myelosuppression with normal doses of azathioprine. Start with reduced starting doses (30%-80% of normal dose) if normal starting dose is 2-3 mg/kg/day (e.g., 0.6 – 2.4 mg/kg/day), and adjust doses of azathioprine based on degree of myelosuppression and disease-specific guidelines. Allow 2-4 weeks to reach steady-state after each dose adjustment. Because a NUDT15 genotype does not appear to have been ordered for this patient, it is not known if NUDT15 results would further influence the recommended dose or drug. Please consult a clinical pharmacist for more information."}
