Being able to get rid of nasal polyps may depend on the initial cause of the polyps. If they are caused by allergies or a sinus infection, treating the allergies or infection will likely work to get rid of the polyps as well. If the polyps seem to be a bit more stubborn, a physician can prescribe a nasal spray with corticosteroids in it to help shrink the polyps to reduce any irritation or swelling that they may be causing, and can eventually get rid of the polyp entirely. Other treatments include an oral (pill that you swallow) steroid, injections of medicine, the placement of a stent to directly treat the polyp with medication, or a procedure to have the polyps surgically removed.
