Hepatitis B vaccine will not protect you against infection with hepatitis A, C, and E, or other viruses that affect the liver. It will also not protect you from hepatitis B if you are already infected with the virus, even if you do not yet show symptoms.
You should not receive this vaccine if you have ever had a life-threatening allergic reaction to any vaccine containing hepatitis B, or if you are allergic to baker’s yeast. You also should not receive this vaccine if you have received cancer chemotherapy or radiation treatment in the past 3 months.
Before receiving this vaccine, tell the doctor if you have:
- multiple sclerosis;
- kidney disease (or if you are on dialysis);
- a bleeding or blood clotting disorder such as hemophilia or easy bruising;
- a history of seizures;
- a neurologic disorder or disease affecting the brain (or if this was a reaction to a previous vaccine);
- an allergy to latex rubber;
- a weak immune system caused by disease, bone marrow transplant, or by using certain medicines or receiving cancer treatments; or
- if you are taking a blood thinner such as warfarin (Coumadin).
You can still receive a vaccine if you have a cold or fever. In the case of a more severe illness with a fever or any type of infection, wait until you get better before receiving this vaccine.
FDA pregnancy category C. This medication may be harmful to an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.
It is not known whether hepatitis B vaccine passes into breast milk or if it could harm a nursing baby. Do not receive this vaccine without telling your doctor if you are breast-feeding a baby.
There are no restrictions on food, beverages, or activity before or after receiving this vaccine, unless your doctor has told you otherwise.
An overdose of this vaccine is unlikely to occur.
Contact your doctor if you will miss a booster dose or if you get behind schedule. The next dose should be given as soon as possible. There is no need to start over.
Be sure you receive all recommended doses of this vaccine. If you do not receive the full series of vaccines, you may not be fully protected against the disease.
You should not receive a booster vaccine if you had a life-threatening allergic reaction after the first shot.
Keep track of any and all side effects you have after receiving this vaccine. When you receive a booster dose, you will need to tell the doctor if the previous shots caused any side effects.
Becoming infected with hepatitis B is much more dangerous to your health than receiving the vaccine to protect against it. Like any medicine, this vaccine can cause side effects, but the risk of serious side effects is extremely low.
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
Call your doctor at once if you have any of these serious side effects:
- fever, sore throat, and headache with a severe blistering, peeling, and red skin rash;
- fussiness, irritability, crying for an hour or longer;
- fast or pounding heartbeats; or
- easy bruising or bleeding.
Less serious side effects include:
- redness, pain, swelling, or a lump where the shot was given;
- headache, dizziness;
- low fever;
- joint pain, body aches;
- tired feeling; or
- nausea, vomiting, stomach pain, constipation, diarrhea.
This is not a complete list of side effects and others may occur. Tell your doctor about any unusual or bothersome side effect. You may report side effects to FDA at 1-800-FDA-1088.
Before receiving this vaccine, tell the doctor about all other vaccines you have recently received.
Also tell the doctor if you have received drugs or treatments in the past 2 weeks that can weaken the immune system, including:
- an oral, nasal, inhaled, or injectable steroid medicine;
- medications to treat psoriasis, rheumatoid arthritis, or other autoimmune disorders, such as azathioprine (Imuran), efalizumab (Raptiva), etanercept (Enbrel), leflunomide (Arava), and others; or
- medicines to treat or prevent organ transplant rejection, such as basiliximab (Simulect), cyclosporine (Sandimmune, Neoral, Gengraf), muromonab-CD3 (Orthoclone), mycophenolate mofetil (CellCept), sirolimus (Rapamune), or tacrolimus (Prograf).
If you are using any of these medications, you may not be able to receive the vaccine, or may need to wait until the other treatments are finished.
There may be other drugs that can affect this vaccine. Tell your doctor about all the prescription and over-the-counter medications you have received. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor.
