Usage Guidelines
For clinical use by qualified healthcare providers. Measure required insertion depth: from the tip of the patient's nose to the earlobe, then down to the xiphoid process (NEX measurement). Lubricate distal end with water-soluble jelly. Advance gently through the chosen patent nostril while patient flexes neck and swallows sips of water. MANDATORY VERIFICATION: Check correct gastric placement before administering any fluid/feed (aspirate gastric contents and verify acidic pH <= 5.5 with pH paper, or obtain chest X-ray). NEVER rely solely on the air whoosh test.
General Administration Advice: Adhere strictly to the prescribed dosage, frequency, and treatment course. For oral medications, swallow with sufficient water. Never stop antibiotics, psychiatric medications, or antihypertensives abruptly without clinical direction.
Possible Side Effects
Common: Nasal discomfort, sore throat, gagging, sneezing. Rare/Severe: Accidental bronchopulmonary intubation / aspiration pneumonia, esophageal perforation, epistaxis, and sinusitis.
*Note: Individual physiological responses vary. While many patients experience few or no side effects, notify your treating physician if adverse reactions persist or if hypersensitivity (angioedema, skin rash, dyspnea) occurs.
Precautions & Warnings
Black Box Safety Mandate: ALWAYS verify correct gastric placement (pH <= 5.5 or X-ray) before administering enteral feeds, fluids, or medications (accidental pulmonary placement causes fatal aspiration). Single-use only. Do NOT force against anatomical resistance.
