Question 1

How quickly does EpiPen start working?

Accepted Answer

Adrenaline begins to act within 1–2 minutes of intramuscular injection. Full reversal of hypotension and bronchospasm is usually seen within 5 minutes.

Question 2

Why do I need to carry two EpiPens?

Accepted Answer

A single dose may not be sufficient, especially if medical help is delayed. Around 20% of people require a second dose. Always carry two.

Question 3

What are the common side effects of EpiPen?

Accepted Answer

Palpitations, pallor, tremor, anxiety, headache, dizziness, and nausea. These are due to adrenergic stimulation and usually resolve quickly.

Question 4

Can I use EpiPen if I have heart disease?

Accepted Answer

Yes, anaphylaxis itself strains the heart more than adrenaline. Use it without delay – it is life‑saving. Inform emergency staff afterwards.

Question 5

What happens if EpiPen is accidentally injected into a finger?

Accepted Answer

Go immediately to A&E. The finger may become pale, cold, and numb due to vasoconstriction. Medical assessment is essential.
