Naphthyzinum (Naphazoline Nitrate)

Naphazoline nitrate, the active ingredient in Naphthyzinum, is an imidazoline sympathomimetic (vasoconstrictor) presented as a nasal spray for nasal administration. It relieves nasal congestion associated with rhinitis and other upper‑respiratory conditions in adults and children. GNH USA supplies Naphthyzinum as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Naphthyzinum is a nasal decongestant that acts on the upper‑respiratory tract to reduce swelling of the nasal mucosa. - Nasal congestion: provides rapid relief of blocked nasal passages. - Allergic rhinitis: diminishes swelling and improves airflow during allergic episodes. - Non‑allergic rhinitis: eases congestion caused by irritants or vasomotor changes.

Naphthyzinum may cause local and systemic reactions after nasal use.

Common Side Effects: - Burning or stinging sensation in the nose. - Nasal dryness or irritation. - Sneezing shortly after application. - Mild headache. - Transient increase in blood pressure.

Serious or Rare Side Effects: - Persistent nasal congestion (rebound effect) after prolonged use. - Severe hypertension. - Cardiac arrhythmias. - Allergic reactions such as rash, itching, or swelling of the face. - Nasal ulceration or tissue necrosis with excessive dosing.

Before using Naphthyzinum, consider the following safety measures. - Cardiovascular disease: avoid if you have uncontrolled hypertension or heart disease. - Glaucoma: use with caution, especially angle‑closure type. - Diabetes: monitor blood pressure as vasoconstriction may affect glycemic control. - Pregnancy and breastfeeding: safety not established; consult a healthcare professional. - Children under 6 years: not recommended without medical advice. - Store at below 25°C: keep in the original container, protect from moisture and direct sunlight.

Naphthyzinum can interact with other medications that affect vascular tone or blood pressure.

Major Interactions (Avoid): - Monoamine oxidase inhibitors (MAOIs): may cause excessive hypertensive response. - Other nasal decongestants (e.g., oxymetazoline): risk of severe vasoconstriction and rebound congestion.

Moderate Interactions (Monitor Closely): - Antihypertensive drugs (beta‑blockers, ACE inhibitors): may blunt blood‑pressure‑lowering effect. - Tricyclic antidepressants: possible additive increase in blood pressure. - Cocaine or sympathomimetic agents: heightened risk of cardiovascular adverse events.
