Xoline Nasal Drops contain Xylometazoline 0.01% w/v, a topical nasal decongestant indicated for the relief of nasal congestion associated with conditions such as allergic rhinitis, common cold, sinusitis, and other upper respiratory tract infections. Xylometazoline is a sympathomimetic agent that acts on alpha-adrenergic receptors in the nasal mucosa, leading to vasoconstriction and subsequent reduction in nasal blood flow. This mechanism effectively decreases mucosal edema and facilitates improved nasal airflow. Xoline Nasal Drops provide rapid onset of action, typically within minutes of administration, offering symptomatic relief that can last up to 10 hours. The product is intended for short-term use, generally not exceeding 7 consecutive days, to prevent rebound congestion (rhinitis medicamentosa). It is contraindicated in patients with hypersensitivity to xylometazoline or any component of the formulation. Caution is advised in individuals with hypertension, cardiovascular disorders, hyperthyroidism, diabetes, or prostatic hypertrophy due to potential systemic absorption and sympathomimetic effects. Use in pediatric populations should follow professional guidance to ensure appropriate dosing. Xoline Nasal Drops should be administered as directed, and patients are advised to avoid concurrent use with other nasal decongestants or systemic sympathomimetics. Discontinuation and consultation with a healthcare provider are recommended if symptoms persist beyond one week.
