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.
Bleeding disorders and anticlotting medications: People with bleeding disorders and people taking anticlotting medications may be at an increased risk for bleeding. Talk to your doctor if this is a concern for you.
Guillain-Barre syndrome: If you developed Guillain-Barre syndrome (a nervous system disorder) within 6 weeks of an immunization with a previous dose of vaccine containing tetanus toxoid, you should discuss the risks and benefits of this vaccine with your doctor.
Immune system: As with any vaccine, this vaccine may not be as effective for people with a weakened immune system (such as those on chemotherapy, people who have had an organ transplant, or people with HIV). If you are taking any medications that suppress your immune system, you may have to wait until treatment has stopped before receiving this vaccine. Talk to your doctor.
Vaccine protection: As with any vaccine, this vaccine may not protect 100% of people who receive it.
Pregnancy: If you are pregnant, it may be necessary to wait until the second trimester of pregnancy to receive this vaccine. Talk to your doctor about the risks and benefits of receiving this vaccine.
Breast-feeding: If you are breast-feeding, talk to your doctor about the risks and benefits of receiving this vaccine.
