Note: This document contains side effect information about hepatitis b pediatric vaccine. Some of the dosage forms listed on this page may not apply to the brand name Engerix-B Pediatric.

For the Consumer

Applies to hepatitis b pediatric vaccine: intramuscular suspension

Get emergency medical help if your child has signs of an allergic reaction: hives; difficulty breathing; swelling of the face, lips, tongue, or throat.

Your child should not receive a booster vaccine if he or she had a life-threatening allergic reaction after the first shot.

Keep track of any and all side effects your child has after receiving this vaccine. When the child receives a booster dose, you will need to tell the doctor if the previous shot caused any side effects.

Becoming infected with hepatitis B is much more dangerous to your child's health than receiving this vaccine. However, like any medicine, this vaccine can cause side effects but the risk of serious side effects is extremely low.

Call your doctor at once if your child has:

  • high fever, sore throat, and headache with a severe blistering, peeling, and red skin rash;

  • fussiness, irritability, crying for an hour or longer;

  • unusual muscle weakness;

  • changes in behavior; or

  • severe skin reaction--fever, sore throat, swelling in your face or tongue, burning in your eyes, skin pain followed by a red or purple skin rash that spreads (especially in the face or upper body) and causes blistering and peeling.

Common side effects include:

  • diarrhea, loss of appetite;

  • feeling weak or tired;

  • mild fussiness or crying;

  • low fever; or

  • runny nose.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects.
