What is a common side effect of administering epinephrine during anaphylaxis management?

Epinephrine is a crucial medication used to treat anaphylaxis, primarily because it acts as a potent vasoconstrictor and bronchodilator. One of the well-known side effects of epinephrine administration is hypertension, which is an increase in blood pressure. This effect is primarily due to the stimulation of alpha-adrenergic receptors, leading to vasoconstriction, which increases systemic vascular resistance and subsequently elevates blood pressure.

In the context of anaphylaxis, the cardiovascular collapse may occur, and the administration of epinephrine helps reverse this by improving perfusion and alleviating symptoms associated with the hypersensitivity reaction. Although hypertension can pose a risk, especially in patients with pre-existing cardiovascular conditions, it is generally a desired effect in the acute management of anaphylaxis as it counters the hypotensive state commonly seen during severe allergic reactions.
