Nazopass (Oxymetazoline Hydrochloride)

Nazopass, containing oxymetazoline, is used as a topical nasal decongestant to alleviate swelling of the nasal passages.

• Common cold: provides rapid reduction of nasal blockage, improving breathing.
• Sinusitis: decreases mucosal edema, helping relieve sinus pressure and congestion.
• Allergic rhinitis: alleviates nasal congestion caused by allergen‑induced inflammation.

• Oxymetazoline acts as a selective alpha‑adrenergic receptor agonist on the α1 and α2 receptors of the nasal mucosal blood vessels. Activation of these receptors induces vasoconstriction, which reduces blood flow and edema in the nasal lining. The resulting decrease in mucosal swelling opens the nasal airway, providing temporary relief of congestion without significant systemic effects when used as directed.

Oxymetazoline nasal spray may cause local and systemic adverse reactions, most of which are mild and transient.

Common Side Effects

• Nasal irritation or burning sensation.
• Dryness of the nasal mucosa.
• Sneezing.
• Transient headache.
• Altered taste or bitter aftertaste.

Serious or Rare Side Effects

• Elevated blood pressure or hypertension.
• Rapid heart rate (tachycardia) or palpitations.
• Severe nasal ulceration or bleeding.
• Allergic reactions such as rash, itching or swelling.
• Rebound congestion (rhinitis medicamentosa) with prolonged use.

Before using Nazopass, consider the following precautions to ensure safe and effective use.

• Duration of use: limit treatment to no more than three consecutive days to avoid rebound congestion.
• Cardiovascular conditions: use with caution in patients with hypertension or heart disease.
• Pregnancy and lactation: consult a healthcare professional before use during pregnancy or while breastfeeding.
• Children: not recommended for children under six years of age unless directed by a physician.
• Concomitant nasal products: avoid using other nasal decongestants or sprays simultaneously.
• Store at room temperature: keep the product in its original container, protect from moisture and direct sunlight.

Oxymetazoline can interact with certain medications; awareness of these interactions helps prevent adverse effects.

Major Interactions (Avoid)

• Monoamine oxidase inhibitors (MAOIs): combined use may cause hypertensive crisis.
• Other sympathomimetic agents (e.g., phenylephrine): risk of excessive vasoconstriction and elevated blood pressure.

Moderate Interactions (Monitor Closely)

• Antihypertensive drugs: oxymetazoline may reduce their effectiveness, requiring blood pressure monitoring.
• Tricyclic antidepressants: additive cardiovascular stimulation may occur.
• Other nasal sprays or topical decongestants: increased risk of nasal irritation and rebound congestion.
• Alcohol or sedatives: may enhance systemic side effects such as dizziness.
