Dr. Truong Tan Phat, Head of the Ear, Nose, and Throat Department at Tam Anh General Clinic District 7, explains that vasoconstrictor nasal sprays, upon contact with the nasal lining, rapidly constrict blood vessels, reduce swelling, and clear nasal passages, making breathing easier for patients. However, if used improperly, after the medication's effect wears off, blood flow to the nasal lining can increase, leading to more severe congestion.
Dr. Phat highlights several common mistakes when using nasal spray:
**Prolonged Use of Vasoconstrictor Medication**
Using nasal spray continuously for many days or weeks can cause swelling of the nasal lining, worsening congestion upon discontinuation, leading to prolonged inflammation and challenging treatment. Patients should adhere to a doctor's prescription, typically for about 5-7 days, followed by a follow-up appointment for monitoring and evaluation.
**Using One Type of Medication for Multiple People**
Not all medications are safe for young children, the elderly, or individuals with underlying conditions like high blood pressure and cardiovascular issues. Arbitrarily sharing nasal sprays carries numerous risks, including adverse effects and long-term health consequences.
**Spraying Medication Whenever Experiencing Nasal Congestion**
A runny or congested nose can stem from various causes, such as the flu, allergic rhinitis, or sinusitis. However, many individuals resort to vasoconstrictor nasal sprays whenever they feel congested, even without knowing the underlying cause. This approach can exacerbate symptoms and prolong the recovery period.

**Not Cleaning the Nose Before Spraying Medication**
Spraying medication directly into a nose full of mucus, pus, or dirt prevents the medication from effectively contacting the nasal lining, thereby reducing its therapeutic effect. Patients should rinse their nose with a saline solution before spraying to ensure the medication's full efficacy.
Dr. Phat advises patients not to use vasoconstrictor nasal sprays continuously to merely manage symptoms and delay seeking medical attention, as this can lead to missing the opportunity for proper treatment of the underlying cause. If nasal congestion persists for 7-10 days without improvement, patients should consult an Ear, Nose, and Throat specialist for an accurate diagnosis and appropriate treatment.
