There may be other brand names for this medicine.

You should not receive this vaccine if you have had an allergic reaction to any type of hepatitis A vaccine or to neomycin.

A nurse or other health provider will give you this medicine.
Your doctor will prescribe your exact dose and tell you how often it should be given. This medicine is given as a shot into one of your muscles.
You will receive a first dose of the vaccine and may get a second (booster) dose 6 to 12 months later.

It is important that you or your child receive all doses at the right time. If you miss your scheduled shot, call your doctor to make another appointment as soon as possible.

Make sure your doctor knows if you are using medicines that weaken your immune system, such as a steroid or cancer medicine. Tell your doctor if you are using a blood thinner (such as warfarin, Coumadin®).

Make sure your doctor knows if you are pregnant or breastfeeding, or if you or your child have liver disease, a bleeding problem (such as hemophilia), a weak immune system from a disease or medicine, or severe illness with a fever.
Tell your doctor if you have a cold or the flu, especially if you have a fever. You may need to wait until you are well to receive this vaccine.
Your first shot of the vaccine should be given at least 2 weeks before you may be exposed to the hepatitis A virus. If you already have been exposed to the hepatitis A virus or if you need longer-term protection, you may receive an immune globulin shot when you get the hepatitis A vaccine.
This vaccine may cause a serious type of allergic reaction called anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Tell your doctor right away if you or your child have a rash, itching, swelling of the tongue and throat, or trouble breathing after you get the injection.
Tell your doctor if you or your child are allergic to latex. The needle cover and the rubber plunger of the prefilled syringe contain dry natural latex rubber, which may cause an allergic reaction in people with a latex allergy.
This vaccine may not protect you against hepatitis A infection if you are already infected with the virus at the time you receive the shot.
