What is this medication?
EPIPEN (Epinephrine) is indicated for the management of hypersensitivity reaction, shock/hypotension (may also be used for conditions not listed).
How does this medication work?
EPIPEN (Epinephrine) stimulates alpha-, beta1-, and beta2-adrenergic receptors resulting in relaxation of smooth muscle of the bronchial tree, cardiac stimulation (increasing myocardial oxygen consumption), and dilation of skeletal muscle vasculature; small doses can cause vasodilation via beta2-vascular receptors; large doses may produce constriction of skeletal and vascular smooth muscle.

For EpiPen, holding the device against the leg followed by removing the cap and then compressing has been described for easier administration. Never reinsert needles. Do not administer repeated injections at the same site. Do not inject into the buttocks or into digits, hands, or feet.
