Nasal polyps can be shrunk with steroid medications, and in many cases eliminated with surgery, but they tend to come back. Getting rid of them usually requires a combination of treatments rather than a single fix. The approach depends on how large your polyps are, how much they affect your breathing and sense of smell, and whether you have related conditions like asthma or aspirin sensitivity.
Steroid Sprays: The First Line of Treatment
Corticosteroid nasal sprays are where most treatment plans start. These sprays reduce the inflammation that fuels polyp growth, and over weeks of consistent use, they can shrink polyps enough to restore airflow and improve your sense of smell. The challenge with traditional sprays is that they don’t always reach the areas where polyps tend to grow. Most of the medication deposits in the lower front part of the nasal cavity, while polyps often develop higher and deeper in the sinuses.
A newer delivery system, approved by the FDA in 2017, uses your own exhaled breath to push medication deeper into the nasal passages. In imaging studies comparing this breath-powered device to traditional sprays, roughly 54% of the medication reached the upper and middle regions of the nose, compared to just 16% with a standard spray pump. This matters because reaching those deeper areas is exactly what’s needed for polyps that sit high in the sinus cavities.
Steroid sprays work gradually. You won’t notice a difference after a day or two. Most people need several weeks of daily use before polyps begin to shrink meaningfully. Even then, sprays alone may not be enough for moderate or large polyps.
Oral Steroids for Faster Results
When polyps are large or symptoms are severe, a short course of oral steroids can produce rapid shrinkage, sometimes dramatic enough that doctors call it a “pharmacologic polypectomy.” In clinical trials, patients who took oral prednisolone for two weeks showed a significant decrease in polyp size within that window. Those on placebo did not.
The catch is that oral steroids alone don’t keep polyps small. In one well-designed study, the size difference between patients who took oral steroids first and those who didn’t was still visible at 10 weeks but had disappeared by 28 weeks. The most effective strategy was a short burst of oral steroids followed by long-term use of a steroid nasal spray. This combination outperformed topical sprays alone over 20 weeks, particularly for restoring the sense of smell.
Oral steroids carry real side effects when used repeatedly (weight gain, bone thinning, blood sugar spikes), so they’re reserved for periodic use rather than ongoing treatment.
Biologic Medications for Stubborn Polyps
Most nasal polyps in Western populations are driven by a specific pattern of immune overactivity called type 2 inflammation. The immune system produces too much of certain signaling molecules that attract inflammatory cells, trigger swelling, and promote tissue growth. Three injectable biologic medications now target this process directly.
- Dupilumab (approved 2019) blocks two key inflammatory signals and was the first biologic approved specifically for nasal polyps. Clinical trials showed significant improvements in polyp size, nasal congestion, and quality of life.
- Omalizumab (approved 2020) blocks an antibody involved in allergic reactions.
- Mepolizumab (approved 2021) targets a signal that keeps a type of inflammatory white blood cell alive and active.
These are typically reserved for people whose polyps keep coming back despite surgery and steroid treatment. They’re given as injections every few weeks and can be highly effective, but they’re expensive and require ongoing use to maintain results.
Surgery: What It Involves and What to Expect
When medications can’t adequately control polyps, surgery becomes the next step. The standard procedure is endoscopic sinus surgery, where a surgeon uses a thin camera and small instruments inserted through the nostrils to remove polyps and open up blocked sinus passages. There are no external incisions.
Recovery follows a fairly predictable pattern. Expect to feel tired and congested for about a week, and plan to take that time off work. Your doctor will likely schedule a follow-up within the first week to check healing and remove any nasal packing. For the first two weeks, you’ll need to avoid exercise, heavy lifting (anything over 5 to 10 pounds), and bending or straining. Anti-inflammatory pain relievers like ibuprofen and aspirin also need to be avoided for two weeks after the procedure. Full healing typically takes four to six weeks.
Surgery provides significant symptom relief. In one long-term study, patients’ symptom scores dropped from 61 out of 100 before surgery to 17 at three months, a substantial improvement. By two years, scores had crept back up to 32, still much better than baseline but a sign that the underlying inflammation doesn’t go away just because the polyps have been removed. About 8% of patients in that study needed a second surgery within two years.
Polyps Come Back: Recurrence Rates
This is the reality that frustrates many people with nasal polyps. Even after successful surgery, the polyps regrow in a significant number of patients. Five-year recurrence rates sit around 30%, and by 10 years, roughly two-thirds of patients have experienced regrowth. This is why long-term management with steroid sprays or biologics after surgery is so important. Surgery removes the polyps; ongoing medication tries to prevent them from returning.
Aspirin Sensitivity and Polyps
Some people have a specific condition where nasal polyps, asthma, and a sensitivity to aspirin or ibuprofen all occur together. If this describes you, there’s a targeted treatment worth knowing about: aspirin desensitization. Under medical supervision (typically in a hospital or clinic), you’re given gradually increasing doses of aspirin over one to two days until your body stops reacting to it. You then take aspirin daily going forward.
Results vary, but long-term studies show that 67% to 85% of patients who complete the process report meaningful improvement in sinus and asthma symptoms, reduced need for steroids, and fewer repeat surgeries. In a five-year follow-up at one large center, 67% reported subjective improvement, while about 22% either saw no benefit or had to stop due to side effects. It’s not a cure for everyone, but for the right patients it can significantly change the course of the disease.
Saline Rinses as Daily Maintenance
Rinsing your nasal passages with saline is one of the simplest things you can do to manage polyp symptoms. It physically flushes out mucus, allergens, and inflammatory debris, and it helps steroid sprays work better by clearing the way for medication to reach the tissue. Squeeze bottles and neti pots are the most common tools.
Despite being widely recommended, there’s surprisingly little consensus on the details. Clinical guidelines acknowledge that no studies have definitively answered how many times a day you should rinse, what volume to use, or whether saltier (hypertonic) solutions work better than standard (isotonic) ones. Isotonic saline is generally recommended as a practical choice based on cost, convenience, and safety. Most ENT specialists suggest rinsing once or twice daily, especially before using a steroid spray, but the “best” protocol is still an open question. The important thing is consistency: making it part of your daily routine rather than something you do only when symptoms flare.
How Polyps Are Diagnosed
If you suspect you have nasal polyps, the two main tools your doctor will use are a nasal endoscopy (a thin flexible camera inserted into your nostril) and a CT scan of your sinuses. Endoscopy is quick, done in the office, and has a diagnostic accuracy of about 93% compared to CT. Its strength is spotting polyps that are visible in the nasal passages, with a 98% positive predictive value, meaning that when endoscopy says polyps are there, it’s almost always right. Its weakness is ruling polyps out: the negative predictive value is only 67%, so a normal-looking endoscopy doesn’t guarantee there’s nothing hiding deeper in the sinuses.
CT scanning remains the gold standard because it shows the full extent of sinus disease, including areas endoscopy can’t reach. It’s particularly useful before surgery, when the surgeon needs a detailed map of your sinus anatomy.
