Timing of EpiPen use – there is no case where it would have been better not to shot

What happens if you accidentally shot someone with an EpiPen when they are not anaphylactic?
(Answer) If you inject a normal person, they will feel hot flashes and heart will pound, but it is only a temporary phenomenon and will return to normal in about 15 minutes. The adrenaline is a type of hormone originally produced in an organ in the human body called the adrenal medulla.

It is impossible to predict the course of anaphylaxis. Injecting adrenaline intramuscularly within 30 minutes reduces the risk of multiple doses of adrenaline, decreases the rate of hospitalization, and reduces biphasic reactions that occur over time. Conversely, delayed administration increases the risk of biphasic reactions. Adrenaline (EpiPen) is a drug that prevents severe reactions, and it is crucial that it be injected intramuscularly before anaphylaxis peaks.

Voice is hoarse, throat and chest tightness, dog-barking cough, persistent strong cough, wheezing cough, difficulty breathing
Repeated vomiting, unbearable abdominal pain
Swelling of the face, skin rash all over the body, unbearable itching, pale lips or fingernails, difficult to feel the pulse, tachycardia, drowsiness, fear, headache, limping, leaking urine or stool
If any one of these is present, EpiPen must be used.

There is no “don’t inject or shouldn’t have injected” situation for EpiPen prescribed.
