Let's take a minute to talk about your medication.  

This is Adacel Tdap vaccine. It helps protect against three serious diseases: tetanus, diphtheria and pertussis or 'whooping cough'.  These diseases are caused by bacteria. They can cause serious harm or death. 

This Tdap vaccine is given to children at age 11 or 12, to adults at certain times, and to pregnant women to protect their newborn baby from pertussis. 

It is given as a shot with a very small needle. It is usually given in the upper arm. 

Most people tolerate this vaccine well. Common side effects include reactions where the shot was given, like pain, redness, swelling or tenderness. Others include getting a headache, fever, or chills. You could also have nausea, a stomach ache or diarrhea, or feel achy or tired. These effects are normal if they are mild, and should go away.  If you are concerned about these or other effects, please talk to your doctor or pharmacist.

As with any vaccine, rare but more serious side effects could occur. These include fainting, an allergic reaction, or difficulty moving the arm where the shot was given. Get medical help right away if you notice any changes that concern you, like a very high fever, unusual behavior, swelling in the face and throat, problems breathing or dizziness. For more information, be sure to read the Vaccine Information Sheet.

For best results with Adacel Tdap vaccine, ask if you will need another vaccine in the future for added protection from these serious diseases.
