How should I take entecavir?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Take entecavir on an empty stomach, at least 2 hours before or 2 hours after eating.
Measure liquid medicine carefully, using the dosing syringe with your medicine (not a kitchen spoon). Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.
Entecavir doses are based on weight (especially in children and teenagers). Your dose needs may change if you gain or lose weight.
Use entecavir regularly to get the most benefit and to keep your condition from getting worse. Call your doctor if your hepatitis symptoms do not improve, or if they get worse.
Do not change your dose or dosing schedule without your doctor's advice. Every person with HBV should remain under the care of a doctor.
Store entecavir at room temperature away from moisture, heat, and light. Keep the bottle tightly closed when not in use.
Keep the bottle of oral liquid in its original carton. Throw away any unused entecavir oral liquid after the expiration date on the label has passed.
Hepatitis B may become active or get worse in the months after you stop using entecavir. You may need frequent liver function tests while using this medicine and for several months after your last dose.
