Product Description:

This page covers pegylated interferon alfa, interferon alfa joined to polyethylene glycol so it stays in the circulation for days and can be injected once a week. Interferon alfa binds cell receptors and switches on antiviral and immune-modulating genes. There is no interferon alpha-1a: the 180 microgram strength matches peginterferon alfa-2a, given as a fixed dose, while 120 and 150 micrograms are presentations of peginterferon alfa-2b, which is dosed by body weight. The two are different products, not interchangeable, and both are injected under the skin.

For chronic hepatitis C, direct-acting antivirals have largely replaced interferon-based treatment. Peginterferon alfa-2a remains in use for chronic hepatitis B, usually as a fixed 48-week course in selected patients, and in chronic hepatitis delta, where options are few. Flu-like symptoms, fatigue, depression, thyroid disorders and falls in white cells and platelets are common, so blood counts, thyroid and liver tests and mood are monitored. It is contraindicated in decompensated cirrhosis and autoimmune hepatitis, and pregnancy must be avoided when it is combined with ribavirin.

Sourcing notes. State clearly whether you need alfa-2a or alfa-2b, with strength and device, because they are prescribed differently and availability varies by market. Both are biological medicines stored at 2-8°C and not frozen, so ask for temperature records for every shipment and the remaining shelf life on arrival. Request the batch CoA, batch release certificate, GMP certificate and CoPP; national lot release applies in some countries. It is prescription-only, used by hepatologists and infectious disease specialists. For tenders, give weekly dose, patient numbers and course length.
