Nezequr (Oxymetazoline Hydrochloride)

Oxymetazoline Hydrochloride, the active ingredient in Nezequr, is an alpha‑adrenergic agonist presented as a nasal spray for nasal administration. It generally provides an effective, temporary relief of nasal congestion commonly caused by colds, allergies, or sinus inflammation in adults and children.

The company maintains stringent manufacturing standards and provides comprehensive documentation to support import and distribution requirements across multiple jurisdictions.

Oxymetazoline Hydrochloride, an alpha‑adrenergic agonist, is employed to alleviate nasal congestion by constricting blood vessels in the nasal mucosa. - Nasal congestion: provides rapid, temporary relief of blocked nasal passages due to common colds, sinusitis, or environmental irritants. - Allergic rhinitis: reduces nasal mucosal swelling and improves breathing in seasonal or perennial allergy sufferers. - Sinus pressure: alleviates pressure and fullness associated with sinus congestion, enhancing comfort during upper respiratory infections.

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

Common Side Effects: - Nasal irritation: mild burning, stinging or tingling sensation in the nasal passages shortly after use. - Dryness: dryness of the nasal mucosa that may cause crusting or a feeling of tightness. - Bitter taste: an unpleasant metallic or bitter taste that can be noticed after spraying.

Serious or Rare Side Effects: - Rebound congestion: worsening nasal blockage after prolonged use, known as rhinitis medicamentosa, requiring discontinuation. - Hypertension: a rise in blood pressure that may occur in patients with pre‑existing cardiovascular conditions. - Severe nasal ulceration: development of tissue damage or ulceration within the nasal cavity, requiring medical evaluation.

When using Oxymetazoline Hydrochloride nasal spray, certain precautions help minimize risks and ensure safe use. - Duration of use: limit application to no more than three consecutive days to avoid rebound congestion. - Cardiovascular conditions: avoid or use with caution in patients with hypertension or other cardiovascular diseases. - Age restrictions: not recommended for children under six years of age unless directed by a healthcare professional. - Drug interactions: consult a physician before combining with monoamine oxidase inhibitors or other sympathomimetic agents. - Pregnancy and lactation: use only if clearly needed and after medical advice, as safety data are limited. - Store at room temperature: keep below 25 °C, in the original packaging, protected from moisture and direct sunlight.

Oxymetazoline Hydrochloride can interact with other medicines, affecting blood pressure or enhancing vasoconstrictive effects.

Major Interactions (Avoid): - Monoamine oxidase inhibitors (MAOIs): concurrent use may cause hypertensive crisis due to additive sympathomimetic activity. - Other nasal decongestants: combined vasoconstriction can increase risk of severe hypertension and rebound congestion. - Clonidine: may reduce the antihypertensive effect of clonidine, leading to elevated blood pressure.

Moderate Interactions (Monitor Closely): - Antihypertensive agents: Oxymetazoline may diminish the effectiveness of blood‑pressure‑lowering drugs. - Selective serotonin reuptake inhibitors (SSRIs): monitor for possible increases in blood pressure. - Alcohol: may enhance dizziness or hypotensive effects when used together.
