Nasal Polyp Treatment 

Depending on the size and number of nasal polyps, the doctor may use medication, surgery, or both. 


Medications for polyps, which are usually in the form of nasal spray or oral pills, are used to reduce the size of the polyps or minimize their symptoms. Steroid nasal sprays such as fluticasone, budesonide, and mometasone are mainly used to prevent runny noses or reduce the discomfort caused by polyps. Oral medications such as prednisone are prescribed only when the sprays don’t work. Although oral and injectable medications are helpful, they have serious complications, including high blood pressure, eye pressure, etc. Moreover, antibiotics or anti-allergy medications will be prescribed if the cause of nasal polyps is asthma or infection.
