Topical nasal decongestants (Formulary)

Sodium chloride 0·9% given as nasal drops and available over the counter, may relieve nasal congestion by helping to liquefy mucous secretions and may be useful for infants under 3 months.

Topical nasal decongestants often cause rebound congestion; use for no longer than 7 days. Avoid sympathomimetics, such as xylometazoline, in patients taking monoamine-oxidase inhibitors (Antidepressant drugs).
