Hysan Adults (Xylometazoline Hydrochloride)

Xylometazoline Hydrochloride is used as a topical nasal decongestant to relieve swelling of the nasal mucosa in several upper‑respiratory conditions.

• Nasal congestion: reduces swelling of nasal passages, improving airflow.
• Common cold: alleviates blockage caused by viral inflammation.
• Allergic rhinitis: diminishes nasal obstruction due to allergen‑induced edema.
• Sinusitis: helps open sinus ostia by decreasing mucosal congestion.
• Upper‑airway irritation: provides temporary relief of nasal stuffiness from irritants.

• Xylometazoline Hydrochloride acts as a selective alpha‑adrenergic agonist on the α1‑ and α2‑receptors of the nasal mucosal blood vessels. Stimulation of these receptors induces vasoconstriction, which reduces blood flow and edema in the nasal lining, leading to rapid decongestion and improved airway patency. The effect begins within minutes and lasts for several hours, allowing temporary relief without systemic absorption. Because the drug remains largely localized, systemic side effects are uncommon.

Xylometazoline Hydrochloride may cause local and, rarely, systemic adverse reactions.

Common Side Effects

• Burning or stinging sensation in the nose.
• Nasal dryness or crusting.
• Sneezing.
• Mild headache.

Serious or Rare Side Effects

• Rebound congestion (rhinitis medicamentosa) after prolonged use.
• Severe nosebleeds.
• Hypertension or palpitations.
• Allergic reaction with swelling of the face or throat.

Before using Hysan Adults, consider the following precautions to ensure safe and effective treatment.

• Duration of use: limit application to no more than three consecutive days to avoid rebound congestion.
• Age restriction: not recommended for children under 12 years of age.
• Pregnancy and lactation: consult a healthcare professional before use, as safety data are limited.
• Pre‑existing nasal conditions: avoid if nasal mucosa is severely inflamed or ulcerated.
• Concomitant vasoconstrictors: do not combine with other nasal decongestants to prevent excessive vasoconstriction.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Xylometazoline Hydrochloride can interact with certain medicines; awareness of these interactions helps prevent adverse effects.

Major Interactions (Avoid)

• Monoamine oxidase inhibitors (MAOIs): concurrent use may increase the risk of hypertensive reactions.
• Other nasal decongestants (e.g., phenylephrine, oxymetazoline): additive vasoconstriction can cause severe hypertension.

Moderate Interactions (Monitor Closely)

• Antihypertensive agents (beta‑blockers, ACE inhibitors): nasal decongestant may reduce their blood‑pressure‑lowering effect.
• Tricyclic antidepressants: may potentiate sympathomimetic effects.
• Caffeine‑containing products: can enhance stimulant effects leading to jitteriness.
