Nasic (Xylometazoline Hydrochloride, Dexpanthenol)

Nasic, containing xylometazoline and dexpanthenol, addresses nasal congestion and mucosal irritation across several common respiratory conditions.

• Common cold: reduces nasal blockage and eases breathing.
• Sinusitis: alleviates sinus‑related congestion and pressure.
• Allergic rhinitis: diminishes nasal swelling caused by allergens.
• Dry or irritated nasal mucosa: moisturises and supports mucosal healing.

• Xylometazoline Hydrochloride acts as an alpha‑adrenergic agonist, binding to α1‑ and α2‑receptors on the vascular smooth muscle of the nasal mucosa, producing vasoconstriction that reduces oedema and congestion. Dexpanthenol, a provitamin B5 derivative, penetrates the epithelium and is converted to pantothenic acid, promoting cellular regeneration and enhancing moisture retention, thereby supporting mucosal repair. The combined actions provide rapid decongestion while maintaining mucosal integrity.

Nasic may cause local and systemic adverse reactions, most of which are mild and transient. These effects are generally dose‑related and resolve after discontinuation.

Common Side Effects

• Nasal burning or stinging sensation.
• Nasal dryness or crusting.
• Sneezing.
• Mild headache.
• Transient epistaxis (nosebleed).
• Nausea.
• Dry throat.

Serious or Rare Side Effects

• Elevated blood pressure or hypertension.
• Palpitations or tachycardia.
• Severe allergic reaction (rash, swelling, anaphylaxis).
• Persistent nasal congestion (rebound congestion) after prolonged use.
• Cardiac arrhythmia.
• Cerebral ischemia (very rare).

Before using Nasic, consider the following precautions to minimise risks and ensure appropriate use.

• Limit duration of use: restrict to 3‑5 days to avoid rebound congestion.
• Avoid use in patients with severe hypertension or cardiovascular disease.
• Consult a healthcare professional before use during pregnancy or breastfeeding.
• Do not administer to children under the recommended age without medical advice.
• Avoid concurrent use with other nasal decongestant products.
• Store at room temperature: keep in original packaging, protect from moisture and direct sunlight.

Nasic can interact with certain systemic and topical agents; awareness of these interactions helps prevent adverse events.

Major Interactions (Avoid)

• Concomitant use of systemic sympathomimetic drugs (e.g., pseudoephedrine) may cause excessive vasoconstriction.
• Combination with monoamine oxidase inhibitors can increase the risk of hypertensive crisis.
• Use together with other nasal decongestants may amplify local vasoconstrictive effects.
• Concurrent use with ergot alkaloids may precipitate severe vasospasm.

Moderate Interactions (Monitor Closely)

• Co‑administration with antihypertensive medications may reduce their efficacy.
• Concurrent topical ophthalmic decongestants may increase systemic absorption.
• Use with certain antidepressants (tricyclics) may require blood pressure monitoring.
• Combination with caffeine‑containing products may modestly increase systemic stimulation.
