Table of contents:

Hepsera is a prescription antiviral medication used to treat chronic hepatitis B in adults and children over 12 years of age. It contains an active ingredient called Adefovir dipivoxil. Adefovir is in a class of medications called nucleotide analogs. It works by blocking an enzyme that is necessary for the hepatitis B virus to replicate, thereby slowing the growth and spread of the virus in the body. By reducing viral replication, Hepsera can help to reduce inflammation and damage to the liver caused by the virus.

Hepsera is not a cure for hepatitis B, but it can help to manage the condition and prevent complications. It cannot prevent the spread of hepatitis B to other people.

Use and Dosage

Adefovir is available in tablet form and should be taken orally with or without food as prescribed by your doctor, generally once a day. The appropriate dosage will depend on your medical condition and response to treatment and take Adefovir regularly to obtain the maximum benefits.

Do not use Adefovir as the sole treatment for patients infected with both hepatitis B and HIV. Before and during treatment, an HIV test is recommended to ensure you receive appropriate care. Please speak with your doctor or pharmacist for further information.

To help you remember, take it at the same time each day. Do not increase or decrease the dosage or discontinue the medication without the guidance of your doctor or pharmacist. Make sure you refill your prescription before it runs out.

While taking Adefovir, there is a possibility of certain issues, such as worsening of your condition, decreased response to treatment, or being infected with the virus again with resistant strains. If new symptoms arise during or after treatment, immediately inform your doctor.
