Nezeril (Oxymetazoline Hydrochloride)

Oxymetazoline, the active ingredient in Nezeril, is a Alpha-adrenergic agonist presented as a nasal spray for nasal use. It relieves nasal congestion caused by colds, sinusitis and allergic rhinitis in adults and children when appropriate.

GNH USA supplies Nezeril as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Oxymetazoline acts as a topical nasal decongestant to reduce swelling of the nasal mucosa. - Nasal congestion due to common cold: provides rapid relief of blocked nose. - Sinusitis: helps open sinus passages and eases pressure. - Allergic rhinitis: reduces swelling caused by allergen exposure, improving airflow.

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

Common Side Effects: - Nasal irritation or burning sensation. - Dryness of the nasal mucosa. - Sneezing or mild nosebleeds. - Headache. - Altered taste or taste disturbance. - Mild throat irritation.

Serious or Rare Side Effects: - Rebound nasal congestion with prolonged use. - Elevated blood pressure or hypertension. - Cardiac arrhythmias. - Severe allergic reaction (anaphylaxis). - Persistent nasal ulceration. - Vision changes or ocular pressure increase.

Before using Oxymetazoline, consider the following safety measures. - Limit duration of use: do not exceed three consecutive days to avoid rebound congestion. - Pre‑existing cardiovascular disease: use with caution and monitor blood pressure. - Diabetes or thyroid disorders: consult a healthcare professional before use. - Children under six years: avoid unless specifically prescribed. - Pregnancy and breastfeeding: discuss risks with a physician before use. - Store at room temperature: keep below 25 °C, in the original packaging, protected from moisture and direct sunlight.

Oxymetazoline can interact with other medications that affect the sympathetic nervous system.

Major Interactions (Avoid): - Monoamine oxidase inhibitors (MAOIs): may cause excessive vasoconstriction. - Other topical decongestants: risk of severe hypertension. - Tricyclic antidepressants: additive sympathomimetic effects.

Moderate Interactions (Monitor Closely): - Oral antihypertensives: may reduce blood‑pressure‑lowering effect. - Beta‑blockers: possible attenuation of cardiovascular response. - Certain herbal supplements (e.g., ephedra): may increase sympathetic activity.
