Decongestant vasoconstrictors are relatively safe if used appropriately, but their use is associated with many side effects due to their direct effects on adrenergic receptors and stimulation of the nervous system. central nervous system. Common side effects include insomnia, increased blood pressure, restlessness, anxiety, tachycardia, palpitations, arrhythmias, hallucinations, and urinary dysfunction. These vasoconstrictor nasal drops should be avoided in patients with heart disease, hypertension, thyroid disease, diabetes, and benign prostatic hyperplasia (BPH), nor should decongestants be used in patients with are taking monoamine oxidase inhibitors concurrently; This combination can lead to life-threatening hypertension.

Therefore, for children under 2 years old, absolutely do not use nasal sprays containing drugs that cause vasoconstriction.
