AdrenalinAutoInjektor

AdrenalinAutoInjektor is a device designed to deliver a single fixed dose of epinephrine (adrenaline) for the emergency treatment of severe allergic reactions, including anaphylaxis. It is intended for use by laypersons and caregivers when rapid medical help is not immediately available, with the goal of rapidly reversing life-threatening symptoms such as airway swelling, throat tightness, and shock.

The device works by injecting epinephrine intramuscularly, typically into the outer thigh. Epinephrine acts as a vasoconstrictor and bronchodilator, increasing blood pressure, reducing swelling, and helping open airways. Most auto-injectors come in fixed-dose formats, commonly around 0.3 mg for adults and older children, and 0.15 mg for younger children, though regional formulations may vary. If symptoms recur or do not promptly improve, a second dose may be administered after a specified interval, usually several minutes, followed by calling emergency services.

Instructions for use emphasize single-handed operation, removing the safety cap, and pressing the device firmly against the mid-thigh until the dose is delivered. After administration, the device should be kept in place for several seconds, then discarded in a proper sharps container. Patients should seek immediate medical evaluation after use, as symptoms can recur and additional treatment may be required.

Safety considerations include potential side effects such as palpitations, tremors, anxiety, and headache. Epinephrine should be used with caution in individuals with certain heart conditions, psychiatric disorders, or pregnancy, and users should be trained in proper usage. Storage typically requires keeping the device at room temperature, away from heat, with regular checks for expiration. Regulatory approval and labeling vary by country, and regional products may differ in dosage or design.
