Major

Interferon- Alfa (Includes Roferon-A) ↔ Renal Dysfunction

Severe Potential Hazard, High plausibility

Applies to: Renal Dysfunction

Proteinuria (rare), not associated with a decrease in serum protein, is the most common renal toxicity observed with interferon- alfa therapy. Increased BUN and serum creatinine levels, hematuria, acute renal failure and nephrotic syndrome have also be reported. Therapy with interferon- alfa should be administered cautiously to patients with severe renal dysfunction. Renal function should be evaluated in all patients before initiation of interferon- alfa therapy. In addition, patients with any degree of renal impairment should be carefully monitored for laboratory abnormalities and decreased creatinine clearance. A reduced dose of medication is recommended in patients with CrCl less than 30 mL/min.
