When should you use your EpiPen?
These life-threatening allergic reactions can also be accompanied by chest pain, low blood pressure, dizziness, and headaches. Use your EpiPen at the first sign of anaphylaxis. A delay in administering epinephrine can be life threatening. Always call 911 or go to the emergency room after using your EpiPen.
How does epinephrine work for anaphylaxis?
Epinephrine works by reversing the symptoms of anaphylaxis. For example, a person's blood pressure plummets during an anaphylactic reaction because the blood vessels relax and dilate — epinephrine causes the blood vessels to constrict, which raises blood pressure, according to Mylan, the maker of EpiPens.
When anaphylaxis is suspected the second line drug of choice after epinephrine is?
Second-line drugs for the treatment of anaphylaxis Antihistamines (both anti-H1 and anti-H2) and corticosteroids are second-line medications for the treatment of anaphylaxis, since they are not life-saving and, therefore, should not be used as initial or only treatment [58, 78, 79].

What happens if you use EpiPen without needing it?
Unintentional injection of epinephrine can easily occur when handling epinephrine auto-injectors. If the epinephrine is injected by mistake into small areas such as fingers and hands, blood vessels will constrict at the site of injection. This can decrease blood flow to the area.
