Abstract

The imidazoline derivative xylometazoline, an alpha-2-adrenergic agonist, is used as non-prescription nasal preparation due to its vasoconstrictive and decongestive properties. Especially in children, an overdose can quickly cause severe central nervous system depression and cardiovascular adverse effects. In three 3-year-old boys (triplets) a xylometazoline intoxication was diagnosed by toxicological analysis. On admission to an emergency unit all three children were still unresponsive. One triplet showed respiration of 15-20 breaths/min and required oxygen support (3L/min) via face mask; his electrocardiogram revealed sinus bradycardia of 64 beats/min with supraventricular extrasystoles. However, no interventions were necessary except fluid management via intravenous lines. Eleven hours after the event, two of the triplets were awake but still not fully oriented. The third triplet woke up 20h after instillation of nose drops. Intoxication was caused by a compounding error in a pharmacy resulting in a concentration 40 times above the adequate dosage for children. In general, physicians, pharmacists and the public should be educated about the toxicity of over-the-counter preparations.
