Hepatitis B
InterferonInterferons are special proteins our body makes to fight off infectious agents such as viruses. Interferon used to treat Hepatitis B is a genetically engineered form of natural interferons. Administered in an injection just under the skin, Interferon is given anywhere from one to three times per week. Those who benefit most from interferon are those patients with active Hepatitis B and active liver disease (indicated by elevated liver enzymes). Side effects include:
- "flu-like" symptoms that usually resolve in 1-2 weeks
- decreased appetite
- muscle and body aches
- headache
- weight loss
- insomnia
- decreased white blood cell count
- elevated liver enzymes
- mood changes such as irritability and anxiety.
Detailed Information About Interferons
One Type of Interferon - Interferon Alfa
Lamivudine (Epivir HBV)
Epivir HBV treats Hepatitis B by blocking the virus's ability to multiply. This drug is given in a higher dose than given as part of an HIV regimen. The most common dose for Hepatitis B is one 100mg tablet each day. Patients remain on therapy for about 1 year. Side effects are rare but if they occur they include:
- an inflammation of the pancreas (pancreatitis)
- numbness and tingling of the feet or hands.

Hepatitis C
Interferon and Pegylated InterferonInterferons are special proteins our body makes to fight off infectious agents such as viruses. Interferon is a genetically engineered form of natural interferons that are given to fight Hepatitis C. Administered in an injection just under the skin, Interferon is given anywhere from one to three times per week. Those who benefit most from interferon are those patients with active Hepatitis C and active liver disease (indicated by elevated liver enzymes). The decision to treat is based on the likelihood of response and the likelihood of developing cirrhosis. Side effects include:
- "flu-like" symptoms that usually resolve in 1-2 weeks
- decreased appetite
- muscle and body aches
- headache
- weight loss
- insomnia
- decreased white blood cell count
- elevated liver enzymes
- and mood changes such as irritability and anxiety.
A special type of interferon called pegylated interferon lasts longer and is tolerated better due to the binding of a polyethylene glycol molecule to interferon. Because it lasts longer, fewer doses have to be given to achieve the same affect.

Interferon / Ribavirin Combination (Rebetron)
Rebetron is a combination of interferon and the antiviral drug Ribavirin. Ribavirin is not effective in treating Hepatitis C alone, so it is used in combination with interferon. Rebetron is given in an injection three times per week. Side effects include all of those present with interferon as well as itching, rash, stomach pain, diarrhea, and anemia.
