See also Warning section.

Entecavir is used to treat long-term hepatitis B infection. Hepatitis B is an infection of the liver caused by the hepatitis B virus. Long-term infection can cause liver damage, rarely liver cancer, and liver failure. Entecavir helps to decrease the amount of hepatitis B virus in your body. It is unknown if this medication lowers your chance of getting liver cancer or liver damage. Entecavir is an antiviral that belongs to a class of drugs known as hepatitis B virus nucleoside reverse transcriptase inhibitors.

Entecavir is not a cure for hepatitis B. It does not prevent the spread of the virus to others through sexual contact or blood/body fluid contamination (such as sharing used needles).

How to Use This Medication

Read the Patient Information Leaflet if available from your pharmacist before you start taking entecavir and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth on an empty stomach (at least 2 hours after a meal and 2 hours before the next meal) as directed by your doctor, usually once daily.

If you are taking entecavir oral liquid, carefully measure your dose with the medicine spoon provided. Do not use a household spoon because you may not get the correct dose. Swallow the medicine directly from the measuring spoon. Do not mix the medication with water or other liquids. Rinse the spoon with water after each use.

The dosage is based on your medical condition and response to treatment. For children, the dosage is also based on weight.

It is very important to keep taking this medication exactly as prescribed by your doctor. Do not skip any doses.

This medication works best when the amount of drug in your body is kept at a constant level. Take this drug at evenly spaced intervals. To help you remember, take it at the same time each day.

Do not take more or less of this drug than prescribed or stop taking it even for a short time unless directed to do so by your doctor. Doing so may cause the amount of virus to increase, make the infection more difficult to treat (resistant), or worsen side effects. See also Warning section.

Tell your doctor if your condition does not get better or if it gets worse.
