{"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. NUDT15 phenotype could not be assigned based on genotyping. Monitor closely for toxicity. Please consult a clinical pharmacist for more information."}
