Pediarix

1 What is Pediarix?

Brand: Pediarix

Generic: Diphtheria, Tetanus, Acellular Pertussis, Hepatitis B and Polio Vaccine

Pediarix is a combination immunizing agent used to prevent illness caused by diphtheria, tetanus, pertussis (a whooping cough), hepatitis B and poliovirus. The vaccine works by causing the body to produce its own protection (antibodies) against these diseases. The vaccine is given only to infants and children who are 6 weeks to 6 years of age and is given before the child’s 7th birthday.

This vaccine combines 5 agents into 1 vaccine. In order to complete the series, you must get three injections of this vaccine at separate intervals. As there are so many different diseases you need to be vaccinated against, be sure to follow your doctor’s orders about your vaccination schedule.

Diphtheria is a serious illness that can cause breathing difficulties, heart problems, nerve damage, pneumonia and possibly death. The risk of serious complications is greater in very young children and the elderly.

Tetanus is a very serious illness that causes convulsions and severe muscle spasms that can be strong enough to cause spine fractures. Tetanus causes death in 30%-40% of cases. The disease continues to occur almost exclusively in people who do not get vaccinated.

Pertussis (a whooping cough) is a serious disease that causes severe coughing fits that can limit breathing. Pertussis may also cause pneumonia, long-lasting bronchitis, seizures, brain damage and death.

Hepatitis B is a major cause of serious liver diseases, including liver cancer. This injection is transmitted through exposure to infected body fluids such as saliva and blood. Pregnant women who have or are carriers of hepatitis B can give the disease to their babies when they are born. These babies often suffer serious long-term illnesses from the disease. People who have the virus can give it to others without knowing it.

Polio is a very serious illness that causes muscle paralysis, including the muscles you use to walk and breathe. A polio infection may leave a person unable to breathe without the help of a breathing machine. It may also leave a person unable to walk without leg braces or being confined to a wheelchair. There is no cure for polio.

This medication is only to be administered by or under the supervision of your doctor or health care professional. This product is available in the following forms:

Proper usage of Pediarix requires strict adherence to your doctor’s orders. A nurse or other trained health professional will give your child this vaccine. It is given as a shot into one of the muscles (intramuscular), normally in the shoulder or thighs.

This vaccine is given as 3 shots. The first dose may be given as early as 6 weeks of age. You will need another dose at 4 and 6 months after the first dose unless your doctor directs you otherwise.

Your child may receive other vaccines at the same time as this one but in a different area of the body. You should receive information sheets about all the vaccines your child receives. Be sure you understand all the information.

Your child may also receive a medication to help prevent or treat some of the minor side effects of the vaccine, such as fever and soreness.
