Oxymetazoline

The commonest story with vasoconstrictor drops runs like this: used during a cold, breathing improved, a week later the nose will not breathe without them at all and the bottle has moved into a pocket. This is drug-induced rhinitis – congestion created by the drug itself. The AEMPS ficha técnica describes the mechanism in one line: in rare cases the product increases symptoms of nasal congestion. The mucosal vessels get used to constant constriction and answer withdrawal with dilation, and the loop closes. The European EPOS 2020 paper on rhinosinusitis names prolonged use of topical decongestants as a cause of chronic nasal obstruction. The way out of the loop is stopping the drops, saline rinses and, at a doctor's decision, an intranasal corticosteroid for the transition. If vasoconstrictor drops were recommended as permanent treatment for congestion, consider seeking a second opinion.

Nose drops for a child with a cold look harmless, which is exactly why they are bought most often. Oxymetazoline is banned under 6 years: the AEMPS ficha técnica states that children are especially prone to systemic absorption of the substance and to its adverse reactions, up to profound central nervous system depression with overdose, too frequent or prolonged use. Spanish toxicologists in Anales de Pediatría 2022 showed the same picture from another side: cold remedies in children cause poisonings and bring no proven benefit. The Guía-ABE chapter on upper respiratory catarrh puts it plainly: none of these drugs relieves symptoms meaningfully. What helps a child with a cold is saline rinses, humid air and time. If vasoconstrictor drops were prescribed to a child under 6, consider seeking a second opinion from a pediatrician.
