Hysan Paediatric (Xylometazoline Hydrochloride)

Xylometazoline Hydrochloride acts locally on the nasal mucosa to reduce swelling and improve airflow in several common upper‑respiratory conditions.

• Nasal congestion due to common cold: provides rapid relief of blocked nose in pediatric patients.
• Sinusitis‑related congestion: decreases mucosal edema to facilitate sinus drainage.
• Allergic rhinitis: alleviates nasal blockage caused by allergic inflammation.

• Xylometazoline Hydrochloride is a selective alpha‑adrenergic agonist that binds to alpha‑1 receptors on the smooth muscle of nasal mucosal blood vessels. Activation induces vasoconstriction, which reduces vascular engorgement, limits plasma exudation, and consequently diminishes mucosal edema and nasal airway resistance.

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

Common Side Effects

• Nasal irritation or burning sensation.
• Dryness of the nasal mucosa.
• Sneezing shortly after administration.
• Mild headache.
• Transient taste disturbance.
• Mild epistaxis (nosebleed).

Serious or Rare Side Effects

• Severe allergic reaction (anaphylaxis) with rash, swelling, or difficulty breathing.
• Significant hypertension or tachycardia.
• Persistent nasal congestion (rebound congestion) after prolonged use.
• Nasal ulceration or perforation.
• Cardiovascular events in susceptible individuals.

Before using Xylometazoline Hydrochloride, consider the following safety measures.

• Age restriction: Use only in children as directed by a healthcare professional.
• Duration limit: Do not exceed three consecutive days of use to avoid rebound congestion.
• Cardiovascular caution: Avoid in patients with severe hypertension or coronary artery disease.
• Drug interaction vigilance: Use cautiously with other sympathomimetic decongestants.
• Pregnancy and lactation: Safety has not been established; consult a physician.
• Store at room temperature: Keep in the original container, protect from moisture and direct heat.

Xylometazoline Hydrochloride can interact with other agents that affect vascular tone or adrenergic pathways.

Major Interactions (Avoid)

• Monoamine oxidase inhibitors (MAOIs): May potentiate hypertensive effects.
• Other topical nasal decongestants: Combined use can increase risk of severe hypertension.

Moderate Interactions (Monitor Closely)

• Systemic sympathomimetics (e.g., pseudoephedrine): May enhance cardiovascular stimulation.
• Antihypertensive medications: May reduce their effectiveness.
• Beta‑blockers: Potential for altered heart rate response.
