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

This medication belongs to a group of medications known as vaccines. It is used to prevent tetanus, diphtheria, and pertussis (whooping cough) for people 4 years of age and older. This medication may also be given to pregnant women to help protect developing babies against whooping cough. This vaccine increases a person's defences against pertussis infection and against the toxins produced by tetanus and diphtheria bacteria. It works by introducing very small amounts of bacterial and toxin components into the bloodstream. Only certain parts of the bacteria are used (therefore they are not alive), and the toxins have been detoxified. Still, these components are enough to stimulate the production of a person's own antibodies (cells designed to attack that particular bacteria or toxin), which will remain in the body ready to attack any future bacteria that may cause infection and deal with the toxins produced during tetanus or diphtheria infection.

This medication may be available under multiple brand names and/or in several different forms.

Are there any other precautions or warnings for this medication?

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: People with bleeding disorders may experience bruising after receiving an injection into a muscle. Tell your doctor about any bleeding problems you may have and 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.

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).

Seizures: If you have a history of seizures or 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 this medication is administered to a pregnant woman it should ideally be given during the third trimester.
