[Malignant hypertension and cardiac decompensation after overuse of nasal decongestant: A case report and literature review]. / Hypertension artérielle maligne et décompensation cardiaque globale après consommation abusive de vasoconstricteur par voie nasale : à propos d'un cas et revue de la littérature.

INTRODUCTION: Vasoconstrictors, widely prescribed in the congestive states during acute rhinitis, are responsible for many cases of drug-related iatrogenic disease. CASE REPORT: We report the case of a 40-year-old man, who presented with an episode of malignant hypertensive crisis associated with life-threatening congestive heart decompensation. The patient interview revealed consumption to supra-therapeutic dosage of an association of naphazoline and prednisolone nasal sprays. The diagnostic work-up allowed to rule out disease-related causes of secondary hypertension. The drug-related disease was thus retained. CONCLUSION: The results of the literature review showed many cases of vasoconstrictor poisoning responsible for central nervous system and cardiovascular involvement, especially in young children. This first case of heart failure related to nasal decongestant administration increases the scope of potentially serious risks of these drugs and demonstrates the outreach needs for health professionals and patients about their proper use.
