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

This is an EpiPen Junior. Each pen contains one dose of epinephrine. 

Epinephrine, or adrenaline, is a hormone that the body makes naturally. The body makes a lot of epinephrine when a person is scared or stressed. This raises the heart rate and blood pressure so the person can react. Then, it goes away quickly. 

During a serious allergic reaction, the body needs epinephrine, but does not make enough. EpiPen lets you inject epinephrine into the body. The dose will help the heart and blood pressure stay strong while you call for emergency help. Emergency help is needed to continue treating the allergic reaction. 

Serious allergic reactions can cause death if they are not treated in time. So, do not delay in using the pen. And, it's important not to be afraid of using it. The device is big, but the needle is small, like a flu shot. The dose should be injected into the middle of the outer thigh. It can be injected through clothing if needed. 

After a dose, it's normal to feel a little shaky, or have other effects like anxiety or a strong heartbeat. These are normal and should go away quickly, especially if the person can remain calm. 

You and your family need to become confident using the pen. Your doctor will tell you how and when to use it. You should read the full instructions inside the carton. There is a training device in the carton, so you can practice often. 

You should store EpiPen in the original carton. Check it periodically to make sure it is clear, colorless, not expired, and that the blue safety release is intact. 

For best results with EpiPen Junior, use it at the first sign of an allergic reaction.
