Entecavir is a medication used in the treatment of chronic hepatitis B virus (HBV) infection. It belongs to a class of drugs known as nucleoside analog reverse transcriptase inhibitors.

Entecavir works by inhibiting the reverse transcriptase enzyme, which is essential for the replication of the HBV virus. By blocking this enzyme, entecavir helps to reduce the viral load in the body and slow down the progression of hepatitis B.

The medication is typically taken orally in the form of tablets. The dosage and treatment duration depend on various factors such as the severity of the infection, the patient’s liver function, and their previous treatment history.

Regular monitoring of liver function and viral load is important to assess treatment response and adjust therapy if necessary. Adherence to the prescribed dosage is crucial to maintain viral suppression and prevent the development of drug resistance.

Common side effects of entecavir may include headache, fatigue, nausea, and dizziness. More serious side effects, such as liver problems or lactic acidosis, are rare but can occur. It is important to discuss any concerns or potential side effects with a healthcare professional.

Entecavir should only be used under the guidance and prescription of a qualified healthcare professional experienced in the treatment of hepatitis B. It may interact with other medications, so it is important to inform the healthcare provider about all medications being taken, including over-the-counter drugs and supplements.

In summary, entecavir is a medication used in the treatment of chronic hepatitis B infection. It inhibits the reverse transcriptase enzyme to reduce the viral load and slow down the progression of the disease. Regular monitoring and adherence to healthcare provider instructions are important during entecavir treatment.
