• Entecavir is not effective against HIV and may not be suitable for individuals co-infected with both hepatitis B and HIV. It’s important to manage both infections carefully to avoid resistance development.

3. Discontinuation of Treatment:

• Stopping Entecavir suddenly can lead to a flare-up of hepatitis B, potentially causing severe liver damage. Do not stop the medication without consulting your healthcare provider.
