Otrivine Sine Conservans Abschwellend (Xylometazoline Hydrochloride)

Xylometazoline Hydrochloride is an alpha‑adrenergic nasal decongestant that alleviates swelling of the nasal passages.

• Nasal congestion: provides rapid reduction of blockage caused by colds or flu.
• Allergic rhinitis: eases nasal swelling associated with seasonal allergies.
• Sinusitis: helps relieve congestion that contributes to sinus pressure.
• Upper respiratory tract infection: improves airflow during common cold episodes.

• Xylometazoline Hydrochloride acts as a selective alpha‑adrenergic receptor agonist on the smooth muscle of nasal mucosal blood vessels. Stimulation of these receptors induces vasoconstriction, which decreases blood flow and reduces edema in the nasal lining. The resulting shrinkage of swollen tissue opens the nasal airway, providing prompt relief from congestion without significant systemic absorption at the recommended dose.

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

Common Side Effects

• Nasal burning or stinging sensation: mild irritation at the application site.
• Headache: occasional mild headache that resolves spontaneously.
• Dryness of the nasal mucosa: feeling of dryness or crusting inside the nose.
• Sneezing: transient increase in sneezing shortly after use.
• Taste disturbance: temporary alteration of taste perception.

Serious or Rare Side Effects

• Rebound nasal congestion: worsening blockage after using the spray for more than three days.
• Severe hypertension: significant rise in blood pressure requiring medical attention.
• Cardiac arrhythmia: irregular heart rhythm that may be life‑threatening.
• Allergic reaction: rash, itching, swelling, or difficulty breathing indicating hypersensitivity.
• Nasal ulceration: development of sores or ulceration in the nasal lining.

When using Xylometazoline Hydrochloride nasal spray, several precautions should be observed to ensure safe and effective use.

• Limit duration of use: do not exceed three consecutive days to avoid rebound congestion.
• Pre‑existing cardiovascular disease: consult a healthcare professional before use if hypertension or heart disease is present.
• Pediatric use: follow age‑specific recommendations and avoid use in infants under six months.
• Pregnancy and lactation: use only if clearly needed and prescribed by a physician.
• Drug interactions: inform the prescriber of any concurrent monoamine oxidase inhibitors or sympathomimetic agents.
• Store at ambient temperature: keep below 25 °C in the original container, protected from moisture and direct sunlight.

Xylometazoline Hydrochloride can interact with certain medications, altering its effect or increasing the risk of adverse events.

Major Interactions (Avoid)

• MAO inhibitors: concurrent use may cause excessive vasoconstriction and hypertensive crisis.
• Sympathomimetic drugs (e.g., pseudoephedrine): combined effect can lead to dangerously high blood pressure.

Moderate Interactions (Monitor Closely)

• Antihypertensive agents: nasal decongestant may reduce the efficacy of blood‑pressure‑lowering drugs.
• Tricyclic antidepressants: potential for additive cardiovascular stimulation.
• Beta‑blockers: may blunt the systemic vasoconstrictive response, requiring monitoring.
