Naso (Xylometazoline Hydrochloride)

• Xylometazoline Hydrochloride is used as a topical nasal decongestant to reduce swelling of the nasal mucosa.
• Common cold: provides rapid relief of nasal blockage caused by viral upper‑respiratory infection.
• Sinusitis: decreases mucosal edema, improving sinus drainage and easing congestion.
• Allergic rhinitis: alleviates nasal obstruction associated with allergen‑induced inflammation.

• Xylometazoline Hydrochloride acts as a selective alpha‑adrenergic receptor agonist on the smooth muscle of nasal mucosal blood vessels. Stimulation of α1‑ and α2‑receptors induces vasoconstriction, which reduces blood flow, limits plasma exudation, and diminishes mucosal edema. The resulting narrowing of the vascular space opens the nasal airway, providing symptomatic relief. The effect appears within minutes and lasts for several hours, allowing temporary improvement of airflow without systemic absorption at therapeutic doses.

Xylometazoline Hydrochloride may cause local and systemic adverse reactions, most of which are mild and transient.

Common Side Effects

• Burning or stinging sensation in the nose.
• Nasal dryness or crusting.
• Sneezing or mild irritation.
• Headache (occasionally).

Serious or Rare Side Effects

• Rebound nasal congestion (rhinitis medicamentosa) after prolonged use.
• Elevated blood pressure or hypertension.
• Tachycardia or palpitations.
• Severe allergic reactions such as rash, swelling, or anaphylaxis.

• When using Naso, several safety considerations should be observed to minimize risks.
• Duration of use: limit to no more than three consecutive days to avoid rebound congestion.
• Age restrictions: not recommended for children under 6 years without medical advice.
• Cardiovascular conditions: avoid in patients with uncontrolled hypertension or severe heart disease.
• Pregnancy and lactation: use only if clearly needed and prescribed by a healthcare professional.
• Drug interactions: consult a physician before combining with other nasal decongestants or systemic sympathomimetics.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Xylometazoline Hydrochloride can interact with other medicines, influencing its safety or effectiveness.

Major Interactions (Avoid)

• Monoamine oxidase inhibitors (MAOIs): risk of hypertensive crisis when combined with sympathomimetic agents.
• Other nasal decongestants (e.g., phenylephrine, oxymetazoline): additive vasoconstriction may increase systemic side effects.
• Systemic alpha‑adrenergic agonists (e.g., pseudoephedrine): may cause excessive cardiovascular stimulation.

Moderate Interactions (Monitor Closely)

• Antihypertensive drugs (beta‑blockers, ACE inhibitors): nasal decongestant may reduce their blood‑pressure‑lowering effect.
• Cocaine or other nasal irritants: combined use can exacerbate nasal mucosal damage.
• Tricyclic antidepressants: may potentiate sympathomimetic effects, requiring monitoring.
