What is the recommended interval for repeat doses of adrenaline in anaphylaxis?

The recommended interval for repeat doses of adrenaline in the case of anaphylaxis is every 5 minutes. This interval is crucial because anaphylaxis can progress rapidly and can be life-threatening. Administering adrenaline at 5-minute intervals allows for rapid management of symptoms and the possibility of reversing severe allergic reactions effectively.

In cases of anaphylaxis, initial treatment usually involves a single intramuscular injection of adrenaline. If there is no improvement of symptoms after 5 minutes, a second dose can be administered. This approach is based on the pharmacokinetics of adrenaline and the need for timely response in emergency situations.

The options that suggest longer intervals, like 10 or 15 minutes, would delay potentially life-saving treatment in a critical situation, where rapid administration may be necessary to mitigate more severe symptoms or complications.
