Regular nose blockage with continuous use of Otrivin Nasal Spray is commonly caused by rebound congestion, in which the nose becomes more blocked due to frequent spray use. These sprays usually give quick relief for a short time, but using them repeatedly for many days can make the swelling inside the nose return more strongly. Allergy, sinus inflammation, dust exposure, pollution or a deviated nasal septum may add to the long-term blockage. Saline nasal rinses, steam inhalation, hydration and avoiding smoke or dust may naturally help reduce irritation. Doctors often recommend gradually stopping the decongestant spray and using steroid nasal sprays or antihistamine medicines for safer long-term control of allergic swelling and mucus buildup. Do not suddenly increase the spray frequency for relief because this may worsen dependence. Consult your doctor for a proper nasal examination and guidance on safely reducing the spray while controlling congestion.

Using Otrivin Nasal Spray many times a day for several weeks can cause rebound nasal congestion, where the nose becomes more blocked as the effect of the spray wears off. This often makes people depend on the spray more frequently, especially at night. Overuse may also lead to dryness, irritation, palpitations, chest heaviness, or a feeling of breathing discomfort in some individuals. A blocked nose for one month may also be related to allergy, sinus inflammation, infection, or a deviated nasal septum. Steam inhalation, saline nasal rinses, hydration, and reducing dust exposure may help ease symptoms naturally. Doctors commonly use steroid nasal sprays or allergy medicines for longer-term control instead of frequent decongestant spray use. Since you are now having chest heaviness and breathing difficulty, seek medical care soon to rule out asthma, allergy-related breathing problems, or side effects from excessive spray use.
