How to take this medicine

Follow carefully all directions given to you by your doctor. Their instructions may be different to the information in this leaflet.

How much to take

Your doctor will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines.
The usual dose of entecavir is 0.5mg or 1mg once a day.
Do not stop taking your medicine or change your dosage without first checking with your doctor.

How to take it

Swallow the tablet whole with a glass of water.

When to take it

Take this medicine at the same time each day. Taking it at the same time each day will have the best effect and will also help you remember when to take it.
Entecavir should be taken on an empty stomach (at least 2 hours after a meal and 2 hours before the next meal).

How long to take it for

Entecavir helps control your condition but does not cure it. Therefore you must continue taking entecavir for as long as your doctor tells you to.
Entecavir is a very important treatment that can improve the inflammation and scar tissue caused by the hepatitis B virus in your liver and may reduce the chance of developing cirrhosis, liver failure and liver cancer.
It is extremely important that you do not stop taking entecavir without discussing it with your doctor. If entecavir is stopped suddenly, the hepatitis B virus can become very active again and lead to sudden development of severe liver failure. There is a high risk of dying if liver failure develops and liver transplantation may be necessary to save your life.
Make sure you have enough to last over weekends and holidays, or until you next see your doctor.

If you forget to take it

If it is almost time to take your next dose, skip the missed dose and take your next dose at the usual time. Otherwise, take it as soon as you remember and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for missed doses.
This may increase the chance of you experiencing side effects.It is very important not to miss your doses of entecavir. If you have trouble remembering to take your medicine, ask your pharmacist for some hints to help you remember.
