This combination vaccine is used to help prevent infection from the hepatitis A and B viruses. Hepatitis A infection can be mild with no symptoms or a severe illness that can rarely cause liver failure and death. Hepatitis B infection can cause serious problems including liver failure, persistent hepatitis B infection, cirrhosis, and liver cancer. Preventing infection with these viruses can prevent these problems.
Hepatitis A/hepatitis B combination vaccine is made from whole, killed hepatitis A virus and a genetically engineered (man-made in the laboratory) piece of hepatitis B virus. It does not contain live virus, so you can not get hepatitis from the vaccine. This vaccine works by helping the body produce immunity (through antibody production) that will prevent you from getting infection from hepatitis A and hepatitis B. This combination vaccine does not protect you from other virus infections (such as HIV virus which causes AIDS, hepatitis C/ hepatitis E, HPV virus which causes genital warts and other problems).
The vaccine is recommended for people at an increased risk of getting these infections. Those at an increased risk include health care personnel, laboratory workers who handle blood and patient specimens, police, fire and emergency medical personnel who give first aid treatment, hemophiliacs, dialysis patients, people who live with or spend much time with people with persistent hepatitis B or active hepatitis A infections, people with multiple sex partners, men who have sex with men, sex workers, injection drug abusers, and people traveling to high-risk areas.
How to use Twinrix Suspension
A series of 3 injections is usually given over 6 months. Your health care professional will give you a vaccination schedule, which must be followed closely for best effectiveness. If you have an illness with fever at the time a vaccination is scheduled, your health care professional may choose to delay the injection until you are better.
For people who cannot get the vaccine before traveling or for whom the vaccine might not work, your health care professional may also give an injection of immune globulin. Immune globulin contains antibodies against the viruses and will immediately help protect you from developing an infection. However, these antibodies last only a few months. For proper protection, it is important to carefully follow your vaccination schedule.
Rarely, some people have symptoms such as fainting, dizziness, vision changes, or ringing in the ears just after getting a vaccine injection. Tell your health care professional right away if you have any of these symptoms. Sitting or lying down may help, since these symptoms usually don't last long.
Remember that your health care professional has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Before getting hepatitis A/hepatitis B vaccine, tell your health care professional if you are allergic to it; or to other vaccines; or if you have any other allergies. This product may contain inactive ingredients (such as latex rubber, yeast, neomycin, formalin), which can cause allergic reactions or other problems. Talk to your health care professional for more details.
If you are a hemodialysis patient, you may not respond as well to the vaccine and will need to have hepatitis A or B antibody levels checked yearly. If antibodies drop too low over time, you may be given another dose of vaccine (often called a booster shot).
If you have immune system disorders (such as due to HIV infection, certain cancers such as leukemia/lymphoma, cancer or radiation treatment), your body may not make enough antibodies to protect you from hepatitis A or hepatitis B infection. Antibody levels may be checked after the vaccine series.
The elderly may not make as many antibodies to the vaccine. Talk to your health care professional for more details.
During pregnancy, this vaccine should be used only when clearly needed. Discuss the risks and benefits with your health care professional.
It is unknown if this vaccine passes into breast milk. Consult your health care professional before breast-feeding.

Do not start, stop, or change the dosage of any medicines without your doctor's approval.
Laboratory and/or medical tests (such as hepatitis A or B antibody levels) may be performed periodically for some patients at risk of a poor response to the vaccine. Consult your health care professional for more details.
Keep vaccine records for yourself and all of your children, and after your children are grown provide their records to them and their health care professionals. This will prevent unnecessary re-vaccinations.
It is important 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.
