Nasarox Mentol (Oxymetazoline Hydrochloride)

Oxymetazoline Hydrochloride acts on nasal blood vessels to reduce swelling and improve airflow, making it useful for several upper‑respiratory conditions.

• Common cold: reduces nasal blockage and improves breathing.
• Sinusitis: alleviates sinus pressure by decreasing mucosal edema.
• Allergic rhinitis: eases congestion caused by allergic inflammation.

• Oxymetazoline Hydrochloride selectively stimulates alpha‑adrenergic receptors on the smooth muscle of nasal mucosal blood vessels. This activation causes vasoconstriction, which reduces vascular permeability and edema, leading to decreased nasal congestion and improved airway patency.

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.
• Bitter or metallic taste.
• Minor nosebleeds.

Serious or Rare Side Effects

• Rebound nasal congestion (rhinitis medicamentosa) with prolonged use.
• Elevated blood pressure or hypertension.
• Tachycardia or irregular heart rhythm.
• Severe nasal ulceration.
• Allergic reactions such as rash, itching or anaphylaxis.
• Cardiovascular events in susceptible individuals.

When using Oxymetazoline Hydrochloride, certain safety measures should be observed.

• Use in patients with hypertension: monitor blood pressure regularly.
• Avoid prolonged use (>3 days): risk of rebound congestion.
• Do not use in children under 6 years: safety not established.
• Concomitant MAO inhibitor therapy: consult a physician due to possible interaction.
• Pregnancy and breastfeeding: discuss risks with a healthcare professional.
• Store at room temperature: keep in the original container, protect from moisture and heat.

Oxymetazoline Hydrochloride can interact with other medicines that affect vascular tone or the sympathetic nervous system.

Major Interactions (Avoid)

• Monoamine oxidase inhibitors (MAOIs): may precipitate hypertensive crisis.
• Other nasal decongestants (e.g., phenylephrine): increase risk of excessive vasoconstriction.
• Sympathomimetic agents (e.g., ephedrine): can amplify cardiovascular effects.
• Tricyclic antidepressants: may enhance pressor response.

Moderate Interactions (Monitor Closely):\n- Antihypertensive drugs (beta‑blockers, ACE inhibitors): monitor blood pressure for additive effects.

• Selective serotonin reuptake inhibitors (SSRIs): observe for possible serotonin‑related side effects.
• Nasal antihistamine sprays: assess for combined local irritation.
