Pegasys is a trade name for the drug peginterferon alfa-2a, which is a medication used to treat chronic hepatitis B and C infections. Pegasys belongs to a class of drugs known as interferons, which are proteins that help the immune system fight against viral infections.
Pegasys works by stimulating the production of certain immune cells in the body, which helps to suppress the replication of the hepatitis B and C viruses. By doing so, it helps to reduce liver damage, prevent the development of cirrhosis or liver cancer, and improve overall liver function.
Pegasys is typically administered as a subcutaneous injection, either once a week or once every two weeks, depending on the specific condition being treated. The dosage and treatment duration may vary depending on factors such as the individual's response to the medication, underlying liver condition, and viral load.
It is important to note that Pegasys is a prescription-only medication and should only be used under the guidance of a healthcare professional. As with any medication, Pegasys may have potential side effects, including flu-like symptoms, fatigue, depression, and decreased white blood cell count. It may also interact with other medications, so it is crucial to inform the healthcare provider of any other drugs being taken.
In summary, Pegasys is a medication used to treat chronic hepatitis B and C infections by stimulating the immune system's response against the viruses.
