Nezeril (Oxymetazoline Hydrochloride)

Oxymetazoline hydrochloride, the active ingredient in Nezeril, is a alpha-adrenergic agonist presented as a nasal spray for intranasal use. It relieves nasal congestion associated with the common cold, allergic rhinitis and sinusitis 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 nasal spray works on the nasal vasculature to reduce swelling and improve airflow. It is indicated for: - Nasal congestion due to common cold: provides rapid decongestion and easier breathing. - Allergic rhinitis: alleviates nasal blockage caused by seasonal or perennial allergens. - Sinusitis: helps open nasal passages and reduces pressure during acute sinus inflammation.

Oxymetazoline nasal spray may cause unwanted reactions.

Common Side Effects: - Burning or stinging sensation in the nose. - Nasal dryness or irritation. - Sneezing shortly after application. - Mild headache. - Temporary taste disturbance. - Nasal discharge that is clear or watery.

Serious or Rare Side Effects: - Persistent nasal congestion (rebound congestion) with prolonged use. - Elevated blood pressure or tachycardia. - Nasal ulceration or crusting. - Severe headache or facial pain. - Allergic reaction such as rash, itching or swelling. - Vision changes or eye irritation.

Before using Oxymetazoline nasal spray, consider the following precautions: - Age restriction: avoid use in children under the age specified by local regulations. - Duration limit: do not exceed the recommended treatment period (typically no more than three consecutive days). - Cardiovascular conditions: use with caution if the patient has hypertension, coronary artery disease, or arrhythmias. - Pregnancy and lactation: safety has not been established; consult a healthcare professional. - Drug interactions: review concomitant medications that may affect blood pressure. - Store at room temperature: keep in the original packaging, protect from moisture and direct heat.

Oxymetazoline may interact with other agents that influence blood pressure or adrenergic pathways.

Major Interactions (Avoid): - Monoamine oxidase inhibitors (MAOIs): risk of hypertensive crisis. - Sympathomimetic drugs (e.g., epinephrine): additive vasoconstrictive effect.

Moderate Interactions (Monitor Closely):\n- Antihypertensive medications: possible reduction in blood‑pressure‑lowering effect. - Tricyclic antidepressants: may enhance vasoconstriction. - Other nasal decongestants: increased risk of rebound congestion.
