Nesivine Pädiatrie Sine Conservans (Oxymetazoline Hydrochloride)

Oxymetazoline acts on the nasal mucosa to relieve congestion caused by various upper‑respiratory conditions.

• Nasal congestion: reduces swelling of nasal passages for quicker breathing.
• Allergic rhinitis: alleviates blockage due to allergic inflammation.
• Common cold: eases temporary nasal blockage during viral upper‑respiratory infections.

• Oxymetazoline hydrochloride selectively stimulates alpha‑1 adrenergic receptors on the smooth muscle of nasal mucosal blood vessels. This activation causes vasoconstriction, decreasing blood flow and edema in the nasal lining, which opens the airway and reduces the sensation of congestion.

Oxymetazoline is generally well tolerated, but adverse reactions can occur.

Common Side Effects

• Nasal irritation or burning sensation.
• Dryness of the nasal mucosa.
• Sneezing or mild nosebleeds.
• Headache.
• Transient taste disturbance.
• Rebound congestion with prolonged use.

Serious or Rare Side Effects

• Elevated blood pressure or hypertension.
• Tachycardia or irregular heart rhythm.
• Severe nasal ulceration or tissue necrosis.
• Allergic reactions such as rash, itching, or swelling.
• Cardiovascular events in susceptible individuals.
• Central nervous system effects like dizziness or anxiety.

Before using Oxymetazoline, consider the following safety measures.

• Duration of use: limit to no more than three consecutive days to avoid rebound congestion.
• Cardiovascular conditions: avoid in patients with uncontrolled hypertension or severe heart disease.
• Glaucoma: contraindicated in narrow‑angle glaucoma due to potential intra‑ocular pressure increase.
• Pregnancy and lactation: use only if clearly needed; safety data are limited.
• Eye contact: keep the product away from the eyes; rinse with water if accidental exposure occurs.
• Store below 25°C: keep in the original container, protect from moisture and direct sunlight.

Oxymetazoline may interact with other medications that affect vascular tone or blood pressure.

Major Interactions (Avoid)

• Monoamine oxidase inhibitors (MAOIs): risk of hypertensive crisis.
• Other nasal decongestants: additive vasoconstriction may increase systemic effects.
• Sympathomimetic agents (e.g., pseudoephedrine): can amplify cardiovascular stimulation.

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

• Tricyclic antidepressants: possible additive increase in blood pressure.
• Beta‑blockers: monitor for altered heart rate responses.
• Anesthetic agents: may potentiate vasoconstrictive effects during surgery.
