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

Epinephrine belongs to a family of medications called sympathomimetics. These medications resemble chemicals that are normally found in our bodies and are released during stressful situations, such as when we are scared, anxious, or angry.

Epinephrine is used for the emergency treatment of severe allergic reactions (anaphylaxis) to insect bites, insect stings, food, medication, as well as other allergens (e.g., latex). During a severe allergic reaction, blood pressure can become dangerously low, breathing can become difficult, and the face and throat can swell. Others signs and symptoms can include hives, flushing, fast heart rate, paleness, weakness, dizziness, stomach cramps, nausea, vomiting, and diarrhea. Epinephrine works to reverse these effects.
