How does this medication work? What will it do for me?

This medication belongs to the family of medications known as vaccines. It is used to prevent infections such as meningitis, pneumonia, and blood infections caused by the bacteria Neisseria meningitidis groups A, C, Y, and W-135. It works by causing your immune system to make antibodies (substances produced by the immune system designed to attack that particular bacteria). These antibodies stay in the body, ready to attack these bacteria, thereby reducing the risk of infection.

It is given to people who are 6 weeks to 55 years of age. It starts to work several days to a few weeks after the vaccine is given.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here.

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.

Bleeding problems: There is a risk of increased bleeding or bruising when any intramuscular injection is given to a person who has a bleeding disorder or is taking medications to thin the blood.

Also, this vaccine may not be effective for people receiving immunosuppressive therapy (e.g., some medications used to treat cancer or for transplant recipients).

Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you are or may be pregnant, discuss the risks and benefits of receiving this vaccine.
