What is the first line medication for anaphylaxis?

The first line medication for anaphylaxis is epinephrine. This medication is crucial in treating severe allergic reactions, as it works rapidly to counteract the life-threatening symptoms associated with anaphylaxis. Epinephrine acts as a potent vasoconstrictor, which helps to increase blood pressure and reduce swelling. Additionally, it has bronchodilator effects, which help to open the airways, improving breathing for the patient experiencing an anaphylactic reaction. Administering epinephrine promptly can be the difference between life and death in such emergencies, which is why it is always prioritized in the treatment protocol for anaphylaxis.
