Non-allergic rhinitis
Rhinitis without IgE-mediated allergic mechanism. Includes vasomotor, idiopathic, atrophic, medication-induced subtypes, and infectious rhinitis in viral URI. Histamine plays no or minimal role in pathogenesis; antihistamines are not recommended in standard guidelines.
ICD-10 J30.04 drugs
Also known as: Vasomotor rhinitis, Idiopathic rhinitis, Infectious rhinitis

The drug is promoted for these uses outside international guidelines. Each entry below is analyzed against AEMPS, FDA, EMA, Cochrane and major RCTs.
- DOxymetazolineNot recommended · Topical nasal vasoconstrictor, imidazoline derivativeThe 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.
- DXylometazolineNot recommended · Topical nasal vasoconstrictor, imidazoline derivativeA bottle of xylometazoline that lives in a bag for months is the classic picture of drug-induced rhinitis. The mucosal vessels answer constant constriction with rebound dilation, the nose blocks harder, the person sprays more often and the loop locks in. The European EPOS 2020 paper on rhinosinusitis directly lists prolonged use of topical decongestants among the causes of chronic nasal obstruction. That is exactly why the AEMPS ficha técnica limits the course to a few days. Three things break the loop: stopping the drug, rinsing the nose with saline, and an intranasal corticosteroid prescribed by a doctor while the lining recovers. The first 5 to 7 days after stopping are the hardest. If a vasoconstrictor spray is advised to be «kept handy» for months, consider seeking a second opinion.
- FCetirizineNot recommended · Second-generation antihistaminesCetirizine is not used in non-allergic rhinitis (vasomotor, idiopathic, infectious URI-related, medication-induced). ARIA 2020 and EAACI explicitly separate allergic and non-allergic rhinitis: systemic H1 blockers are not useful in the latter because histamine plays no or minimal role in pathogenesis. Topical azelastine and topical corticosteroids work for vasomotor rhinitis. Oral cetirizine or loratadine «for a runny nose» is an incorrect choice.
- FLoratadineNot recommended · Second-generation antihistaminesLoratadine is not used in non-allergic rhinitis (vasomotor, idiopathic, infectious URI-related, medication-induced). ARIA 2020 and EAACI separate allergic and non-allergic rhinitis: systemic H1 blockers are not useful in the latter because the pathogenesis is not histamine-mediated. Topical azelastine and corticosteroids work for vasomotor rhinitis.
How to read tiers A–F
Evidence tiers belong to the drug-indication pair, not to the drug as a whole: the same substance can be A for one condition and F for another.
- AStrong evidence – first or second line in international guidelines
- BRecommended in selected cases
- CStudy data contradict each other
- DBenefit not proven, no documented harm
- FDocumented harm, or risk without benefit
