How soon should a repeat dose of epinephrine be given in anaphylaxis?

Explanation:
Epinephrine acts quickly to reverse the symptoms of anaphylaxis, but its effects don’t always last long enough to prevent a rebound or ongoing reaction. Because the situation can deteriorate fast, you reassess soon after the first dose and, if symptoms persist or recur, administer a second dose after about three to five minutes. This short interval lets you maintain adrenergic stabilization while monitoring for response, reducing the risk of further airway compromise or shock. Waiting much longer increases danger, and giving a second dose immediately without reassessment isn’t necessary if the first dose is still working.
