What should be done in the case of severe allergic reactions?

In the case of severe allergic reactions, calling emergency services immediately is crucial. Severe allergic reactions, also known as anaphylaxis, can progress rapidly and may involve symptoms such as difficulty breathing, swelling of the throat, or a significant drop in blood pressure. These symptoms can be life-threatening and require prompt medical intervention.

Emergency services can provide advanced care, including the administration of epinephrine, which is essential in reversing the severe symptoms of anaphylaxis. Furthermore, trained medical personnel can assess the casualty's condition more thoroughly and ensure that they receive the necessary treatment once they arrive.

While antihistamines and other measures might be helpful in less severe allergic reactions, they are insufficient in emergencies. Administering water or waiting to see if symptoms improve can delay critical treatment, which could lead to worsening of the condition. Thus, getting professional medical help right away is the most effective course of action in severe allergic reaction situations.
