What is entecavir 0.5 mg (tablet)?
Entecavir 0.5 mg is a prescription oral antiviral tablet used to treat chronic hepatitis B (HBV). It works by blocking HBV replication, which helps lower the amount of virus in the body and reduces liver damage over time.[1]
What is the usual dose of entecavir 0.5 mg?
The 0.5 mg tablet strength is the standard starting dose for many adults with chronic HBV. Dosing may change for people with kidney impairment because entecavir is cleared through the kidneys.[1]
How do patients usually take it?
Patients generally take entecavir by mouth once daily. Many HBV regimens also require consistent use and continued treatment for as long as the prescriber recommends, since stopping can allow HBV to flare.[1]
What side effects are people commonly concerned about?
Common side-effect types reported with entecavir include fatigue, headache, dizziness, and nausea. Patients are also advised to watch for signs of liver problems (for example, worsening jaundice or abdominal pain) and to report unusual symptoms to their clinician promptly.[1]
Who should not take entecavir without medical guidance?
Entecavir needs clinician oversight, particularly for people with kidney disease (dose adjustment), those with liver decompensation, and anyone who is pregnant, trying to become pregnant, or breastfeeding. A prescriber also needs to check for other medications and HBV treatment history because HBV drugs can be switched based on resistance patterns.[1]
