Valcyte is not recommended for adult hemodialysis patients (those with a creatinine clearance less than 10 mL/min) and should be used with caution in patients with reduced kidney function. If you are a kidney patient considering Valcyte, it is crucial to consult with your healthcare provider to ensure that the medication is appropriate for your specific situation and to discuss any potential risks or necessary precautions. Your doctor may need to adjust your dosage or monitor your kidney function more closely during treatment.
