Nesivine Pédiatrie Sine Conservans (Oxymetazoline Hydrochloride)

Oxymetazoline Hydrochloride is an alpha‑adrenergic nasal decongestant used to treat conditions affecting the nasal passages.

• Nasal congestion: provides temporary relief of blocked nasal passages.
• Allergic rhinitis: reduces swelling and mucus production in the nasal mucosa.
• Upper respiratory tract irritation: alleviates congestion symptoms caused by common cold or irritants.

• Oxymetazoline Hydrochloride acts as a selective alpha‑1 and alpha‑2 adrenergic receptor agonist on the vascular smooth muscle of the nasal mucosa. Activation of these receptors induces vasoconstriction, decreasing blood flow and edema, which opens the nasal airway and improves airflow during episodes of congestion.

Oxymetazoline Hydrochloride may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects

• Nasal irritation or burning sensation.
• Dryness of the nasal mucosa.
• Sneezing.
• Mild headache.
• Transient taste disturbance.
• Throat irritation.

Serious or Rare Side Effects

• Hypertension or elevated blood pressure.
• Tachycardia or irregular heart rhythm.
• Severe nasal ulceration or bleeding.
• Allergic reactions such as rash, itching, or swelling.
• Rebound congestion (rhinitis medicamentosa) after prolonged use.
• Cardiovascular events in susceptible individuals.

Before using Oxymetazoline Hydrochloride, consider the following safety measures.

• Use in children under 6 years: not recommended unless directed by a physician.
• Avoid prolonged use: limit to three consecutive days to prevent rebound congestion.
• Do not use with MAO inhibitors: risk of hypertensive crisis.
• Caution in patients with hypertension or cardiovascular disease.
• Pregnancy and breastfeeding: consult a healthcare professional; safety not established.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Oxymetazoline Hydrochloride can interact with other medications; awareness helps minimize risk.

Major Interactions (Avoid)

• Monoamine oxidase inhibitors (MAOIs): may cause severe hypertension.
• Other nasal decongestants: risk of additive vasoconstriction and rebound congestion.
• Sympathomimetic agents (e.g., epinephrine): can amplify cardiovascular effects.

Moderate Interactions (Monitor Closely):\n- Antihypertensive drugs: may reduce their efficacy.

• Beta‑blockers: possible alteration of heart rate response.
• Tricyclic antidepressants: may increase sympathomimetic activity.
