What should I discuss with my healthcare provider before receiving this vaccine (Havrix)?
Hepatitis A vaccine will not protect you against infection with hepatitis B, C, and E, or other viruses that affect the liver. It may also not protect you from hepatitis A 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 A, or if you have received cancer chemotherapy or radiation treatment in the past 3 months.
Before receiving this vaccine, tell your doctor if you have:
- a bleeding or blood clotting disorder such as hemophilia or easy bruising;
- a history of seizures;
- a neurologic disorder or disease affecting the brain;
- 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.
Before receiving the hepatitis A vaccine, tell your doctor if you are pregnant.
It is not known if hepatitis A vaccine passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
How is this vaccine given (Havrix)?
This vaccine is given as an injection (shot) into a muscle. You will receive this injection in a doctor's office or other clinic setting.
You will most likely receive 2 separate injections of the hepatitis A vaccine at 6 months apart, depending on your exposure or risk of infection.
To prevent hepatitis A while traveling, you should receive this vaccine at least 2 weeks before your trip. Your healthcare provider will determine the best dosing schedule for your situation.
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 take.
It is especially important to prevent fever from occurring if you have a seizure disorder such as epilepsy.
