Epinephrine injection is employed in conjunction with emergency medical treatment to address life-threatening allergic reactions triggered by insect bites or stings, foods, medications, latex, and other causes. Additionally, it is used to treat life-threatening low blood pressure associated with septic shock, a severe condition resulting from a widespread infection that may lead to dangerously low blood pressure and organ failure.

Epinephrine belongs to a class of medications known as alpha- and beta-adrenergic agonists or sympathomimetic agents. Its mechanism of action involves relaxing the muscles in the airways and constricting the blood vessels.

Uses and Dosage

Keep this product easily accessible. Before use, ensure it can be easily removed from its carrying case. If not, consult your pharmacist.

Regularly inspect the solution for clarity. If it appears cloudy or changes color to pink or brown, do not use it; instead, replace and discard it.

Different brands of this medication may have varying instructions for preparation and administration. Familiarize yourself in advance with the correct injection process to be prepared if needed. Ensure that someone responsible, like a family member or caregiver, knows the storage location and proper administration in case you’re unable to self-administer. Dosage is determined by your condition, weight, and response to treatment.

Administer the medication into the thigh according to your doctor’s and the manufacturer’s directions. Injection through clothing is possible if necessary. While epinephrine acts swiftly, its effects are short-lived. After using it, seek immediate medical assistance, informing the healthcare professional about the injection. Additional doses might be necessary if symptoms persist or return after the initial dose.

Avoid injecting this medication into the hands, feet, buttocks, or other areas aside from the thigh. If accidental injection occurs in these areas, seek immediate medical attention. When administering to infants or young children, ensure their leg is securely held to prevent injury before and during the injection. Properly discard the injector after use.
