This vaccine is used in infants to help prevent infection from a certain bacteria (Haemophilus influenzae type b) and the hepatitis B virus. Haemophilus influenzae b bacteria can cause a serious, sometimes fatal brain infection (meningitis) and lung infection (pneumonia). Hepatitis B infection can cause serious problems including liver failure, persistent hepatitis B infection, cirrhosis, and liver cancer. Protecting against these infections can prevent these problems.
This vaccine contains killed Haemophilus bacteria and a man-made piece of the hepatitis B virus. It does not contain live virus, so your infant cannot get either of these infections from the vaccine. This vaccine causes the body to make immune defensive substances (antibodies) that can protect you from these infections.
This vaccine is recommended for all infants 6 weeks to 15 months old who are born to mothers who do not have current hepatitis B infection.
This vaccine is not for use in adults.
This vaccine is usually given by injection into a muscle by a health care professional.
A series of 3 injections is usually used when the infant is aged 2 months, 4 months, and 12 to 15 months. Your doctor will give you a vaccination schedule, which must be followed closely for best effectiveness. If your infant has an infection with fever at the time a vaccination is scheduled, your doctor may choose to delay the injection until he/she is better.
Pain/redness/swelling at the injection site, fever, irritability, increased crying, loss of appetite, and increased sleeping may occur. Less common side effects may include bruising at the injection site, vomiting, runny nose, stuffy nose, cold symptoms, cough, and diarrhea. If any of these effects persist or worsen, tell your infant's doctor or pharmacist promptly.
Infrequently, temporary symptoms such as fainting/dizziness/lightheadedness, vision changes, numbness/tingling, or seizure-like movements have happened after vaccine injections. Tell your health care provider right away if your child has any of these symptoms soon after receiving an injection. Sitting or lying down may relieve symptoms.
Remember that your health care professional has prescribed this medication because he or she has judged that the benefit to your child is greater than the risk of side effects. Many infants using this medication do not have serious side effects.
Tell the doctor right away if your child has any serious side effects, including: easy bruising/bleeding, unusually fast/irregular heartbeat, inability to make muscles of the legs/arms/face work (paralysis), mental/mood changes (e.g., unusual behavior, severe drowsiness, stiff neck, closing eyes/turning away from bright light), seizures.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
Contact the doctor for medical advice about side effects. The following numbers do not provide medical advice, but in the US you may report side effects to the Vaccine Adverse Event Reporting System (VAERS) at 1-800-822-7967. In Canada, you may call the Vaccine Safety Section at Public Health Agency of Canada at 1-866-844-0018.
Before using this vaccine, tell the health care professional if your child is allergic to it; or to yeast or latex; or if your child have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this vaccine, tell the health care professional your child's medical history, especially of: bleeding problems (e.g., hemophilia, low platelets, anticoagulant treatment), current illness with fever.
If your child has decreased immune function from other medications (see also Drug Interactions) or other illness (e.g., HIV, leukemia, lymphoma, other cancer), the child's body may not make enough antibodies to protect them from Haemophilus influenza b or hepatitis B infection. Antibody levels should be checked after the vaccine series.
Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products your child uses (including prescription/nonprescription drugs and herbal products) and share it with the doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without the doctor's approval.
Some products that may interact with this vaccine include: corticosteroids (e.g., prednisone), cancer chemotherapy, organ transplant drugs (e.g., cyclosporine, tacrolimus).
Other vaccines may be given at the same time as this vaccine, but should be given with separate syringes and at different injection sites.
Certain lab tests that use a certain lab method (latex agglutination) may be affected by this medication for at least 30 days after the injection, possibly causing false test results. Make sure that all of your infant's doctors and laboratory personnel know that your infant has received this vaccine.
Laboratory and/or medical tests (e.g., hepatitis B antibody levels) may be performed periodically for some patients at risk of a poor response to the vaccine. Consult your child's doctor for more details.
It is important for your child to receive each vaccination as scheduled. Be sure to ask when each dose should be received and make a note on a calendar to help you remember.
Store in the refrigerator. Do not freeze. Keep all medications away from children and pets.
Do not flush medications down the toilet or pour them into a drain unless instructed to do so. Properly discard this product when it is expired or no longer needed. Consult your pharmacist or local waste disposal company.
