Nasivin Dosiertropfer ohne Konservierungsstoffe Baby is a nasal decongestant formulated for infants and young children. Dosing depends on age, with specific guidance generally recommended by manufacturers and pediatric references. Direct answer

• For newborns in the first 4 weeks of life: typically 2–3 drops per nostril, 2–3 times per day.
• From 5 weeks up to 1 year: typically 1–2 drops per nostril, 2–3 times per day.
• Max duration: treatment is usually advised for a short period (often up to 7 days) unless directed otherwise by a healthcare professional.
• Administration notes: the bottle is designed for upright use, and the dropper should be positioned above the nostril with the baby’s head held in a comfortable, slightly reclined position. Avoid overuse, and discontinue if symptoms worsen or if there are signs of adverse reactions.
• Special cautions: use under medical supervision for underweight or premature infants, and in any case of chronic nasal symptoms, fever, or if there is a known sensitivity to the medication.
