What should I discuss with my healthcare provider before receiving this vaccine (Pediarix)?
A hepatitis B vaccine will not protect your child against infection with hepatitis A, C, and E, or other viruses that affect the liver. It may also not protect the child from hepatitis B if he or she is already infected with the virus, even if the child does not yet show symptoms.
Your child should not receive this vaccine if the child is allergic to yeast, neomycin, or polymyxin B, or if the child has ever had a life-threatening allergic reaction to any vaccine containing diphtheria, hepatitis B, pertussis, polio, or tetanus.
Your child should also not receive this vaccine if he or she has:
- severe or uncontrolled epilepsy or other seizure disorder;
- if the child has received cancer chemotherapy or radiation treatment in the past 3 months.
Your child may not be able to receive this vaccine if he or she has ever received a similar vaccine that caused any of the following:
- a very high fever (over 104 degrees);
- a neurologic disorder or disease affecting the brain;
- excessive crying for 3 hours or longer;
- fainting or going into shock;
- Guillain-Barré syndrome (within 6 weeks after receiving a diphtheria, tetanus, or pertussis vaccine);
- seizure (convulsions); or
- a severe skin reaction.
Before receiving this vaccine, tell the doctor if your child has:
- a bleeding or blood clotting disorder such as hemophilia or easy bruising;
- a history of seizures;
- an allergy to latex rubber;
- a weak immune system caused by disease or by taking certain medicines or receiving cancer treatments;
- if the child is taking a blood thinner such as warfarin (Coumadin); or
- if it has been less than 6 weeks since the child last received a vaccine.
Your child can still receive a vaccine if he or she has a cold or fever. In the case of a more severe illness with a fever or any type of infection, wait until the child gets better before receiving this vaccine.
How is this vaccine given (Pediarix)?
This vaccine is given as an injection (shot) into a muscle. Your child will receive this injection in a doctor's office or other clinic setting.
The diphtheria, hepatitis B, pertussis, polio, and tetanus vaccine is given in a series of shots. The first shot is usually given when the child is 2 months old. The booster shots are then given at 4 months and 6 months of age. Your child's individual booster schedule may be different from these guidelines. Follow your doctor's instructions or the schedule recommended by the health department of the state you live in.
Your doctor may recommend treating fever and pain with an aspirin-free pain reliever such as acetaminophen (Tylenol) or ibuprofen (Motrin, Advil, and others) when the shot is given and for the next 24 hours. Follow the label directions or your doctor's instructions about how much of this medicine to give your child.
It is especially important to prevent fever from occurring in a child who has a seizure disorder such as epilepsy.
