Nasentropfen (Xylometazoline Hydrochloride)

• Xylometazoline Hydrochloride is an alpha‑adrenergic agonist used to alleviate nasal congestion in upper‑respiratory conditions.
• Common cold: reduces swelling of nasal mucosa, decreasing blockage and improving breathing.
• Allergic rhinitis: alleviates congestion caused by allergen‑induced inflammation, helping restore normal nasal airflow.
• Sinusitis: helps open congested nasal passages, facilitating drainage and relieving sinus pressure.
• Upper respiratory tract infection: provides rapid decongestion to ease breathing during infection.

• Xylometazoline Hydrochloride acts as a selective alpha‑2 adrenergic receptor agonist on the vascular smooth muscle of the nasal mucosa. Activation induces vasoconstriction, which reduces blood flow, diminishes mucosal edema, and opens the nasal airway. The drug’s high affinity for alpha‑2 receptors ensures a pronounced local response while sparing alpha‑1 mediated cardiovascular effects, and its limited systemic bioavailability minimizes the risk of systemic side effects.

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

Common Side Effects

• Burning sensation in the nose
• Stinging or itching
• Nasal dryness
• Sneezing
• Headache

Serious or Rare Side Effects

• Rebound congestion (rhinitis medicamentosa) with prolonged use
• Elevated blood pressure or tachycardia
• Severe allergic reaction (anaphylaxis, angioedema)

• When using Nasentropfen, consider the following precautions to ensure safe and effective use.
• Duration of use: limit to 3‑5 days to avoid rebound congestion.
• Age restrictions: not recommended for children under 6 years without medical advice.
• Cardiovascular conditions: use cautiously in patients with hypertension or heart disease.
• Concurrent nasal medications: avoid using with other decongestants or topical steroids without guidance.
• Pregnancy and lactation: safety not established; consult a healthcare professional before use.
• Store at room temperature: keep in original container, protect from moisture and direct sunlight.

Xylometazoline may interact with other medicines; review the following categories before co‑administration.

Major Interactions (Avoid)

• MAO inhibitors: may potentiate hypertensive effects.
• Sympathomimetic agents (e.g., phenylephrine, pseudoephedrine): additive vasoconstriction can raise blood pressure.

Moderate Interactions (Monitor Closely)

• Beta‑blockers: may mask tachycardia caused by the drug.
• Antihypertensive medications: nasal decongestant may reduce their efficacy.
• Other nasal decongestants: combined use increases risk of rebound congestion.
