Summary
Pegloticase can induce anti-PEG antibodies that may cross-react with other pegylated drugs such as peginterferon alfa 2a. This could theoretically accelerate clearance of the interferon and reduce its antiviral effect. The clinical significance is not established.
What this interaction means in plain words
Peginterferon alfa 2a and Pegloticase have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Peginterferon alfa 2a belongs to Anti Virals; Pegloticase belongs to Genitourinary.
Why it happens
Anti-PEG antibodies formed against pegloticase may bind the polyethylene glycol moiety of other pegylated drugs and speed their clearance.
