Xylolin 0.05% Nasal Spray is used to relieve nasal congestion in children caused by colds, allergies, or sinusitis. The active ingredient, Xylometazoline Hydrochloride (0.05%), is a decongestant that works by shrinking swollen blood vessels in the nasal passages, helping to open up the airways and improve breathing. This nasal spray provides fast-acting relief from blocked noses and reduces discomfort caused by nasal congestion. Disclaimer: Use as directed by a healthcare professional. Not recommended for use for more than 3 consecutive days to avoid rebound congestion. If symptoms persist or worsen, consult your doctor. Always follow the instructions for use.
