Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Allergic reactions: Rarely, this vaccine may cause severe allergic reactions. For this reason, doctors often ask you to stay in the office for about 30 minutes after having the vaccine so that you can get medical care if you have an allergic reaction. If you notice the signs of a severe allergic reaction (hives; trouble breathing or swallowing; or swelling of the lips, face, throat, or tongue), get medical attention immediately.
Immune system: As with any vaccine, this vaccine may not be as effective for people with a weakened immune system (such as those who are on chemotherapy, who have had an organ transplant, or who have HIV).
Medical conditions: If you bruise easily, have a neurological disorder, have a bleeding problem, have a high fever, have poorly controlled epilepsy, have had an allergic reaction to other vaccines, or have a family history of seizures, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Vaccine protection: As with any vaccine, this vaccine may not protect 100% of people who receive it.
Pregnancy: This vaccine should not be used during pregnancy unless the benefits outweigh the risks. If you discover you may have been pregnant when you received this medication, contact your doctor immediately.
Breast-feeding: It is not known if this vaccine passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
