Patient Medicine Information
Why do I need this medicine?
Hepatitis B vaccine helps protect against hepatitis B infection.

Hepatitis B is an infection of the liver caused by a virus that's spread through blood and body fluids (e.g. blood, semen, vaginal secretion, saliva).
How do I use this medicine?
Hepatitis B vaccine is given by intramuscular (into the muscle) injection.

Your doctor or nurse will administer this vaccine for you.

This medicine is usually given in a series of injection. Your doctor will advise you with your vaccination schedules. You must complete the entire course of the medicine.
What should I do if I have forgotten to use this medicine?
Ensure that you keep all appointments with the doctor so that you do not miss any immunisations.

If you miss an appointment or an injection, alert your doctor or nurse. A replacement appointment or injection should be given as soon as possible.
When should I not use this medicine?
Alert your doctor if you ever had an allergic reaction (rashes, breathlessness, swollen eyes) to Hepatitis B vaccine.
What should I take note of while using this medicine?
Inform your doctor if you have the following conditions:

Vaccination should be postponed to premature babies, or if you are ill, with fever or with an infection.

Hepatitis B vaccine may cause drowsiness or dizziness. If affected, do not drive or take part in any activity in which you need to be alert.

Brief fainting spells can happen after vaccination. Sitting or lying down for about 15 minutes after a vaccination can help prevent fainting and injuries caused by falls.

Some side effects may need immediate medical help. Alert your doctor quickly if you experience any breathlessness, having rashes or swollen eyes. These could be signs of an allergic reaction.
