Adrenaline is the drug of choice for the treatment of anaphylaxis. The indications, available formulations, and rules for prescribing adrenaline for self treatment of anaphylactic reactions in allergic subjects are summarized in this paper. Emergency kits containing adrenaline must be prescribed only to patients with a definite history of anaphylactic reactions or laryngeal oedema. A kit containing Adrenaline DAK 1 mg/ml in a traditional glass ampoule together with a 1 ml syringe and an i.m. cannula is the cheapest solution, and a usable alternative in the patient who after sufficient training feels safe to prepare his own injection. Ana-guard injector is recommended for the allergic adult due to its easy handling and the fact that it contains two doses of adrenaline 0.3 mg. For both children and adults with a low bodyweight, the Epi-Pen automatic injector is recommended. It contains one dose of adrenaline (0.15 or 0.30 mg) and requires no preparation before use. The Adrenalin Medihaler is recommended for the treatment of laryngeal oedema and threatened airway obstruction. Due to the low and unpredictable absorption after inhalation, adrenaline injection is recommended for the treatment of systemic symptoms. Prescribing adrenaline in semi-or automatic injectors requires special permission from the Danish Health Authorities.
