Chronic rhinosinusitis with nasal polyps is a long-term inflammatory condition that can make breathing through your nose difficult and rob you of your sense of smell. Treatment focuses on reducing inflammation, shrinking polyps, and improving your quality of life through medical therapy, innovative biologics, and sometimes surgery.

Understanding Treatment Goals and Options

Managing chronic rhinosinusitis with nasal polyps is about more than just removing growths or easing congestion. The main goal is to control the underlying inflammation that causes symptoms to return again and again. This means helping you breathe more easily, restoring your sense of smell and taste, reducing facial pressure, and preventing the need for repeated surgeries.^[1][2]

Treatment approaches depend on several factors, including how severe your symptoms are, how large your polyps have grown, whether you have other conditions like asthma, and how well you’ve responded to previous treatments. Your age and overall health also play a role in deciding which therapy is right for you.^[3][7]

There are well-established treatments that medical societies recommend as standard care. These include nasal sprays, saline rinses, and oral medications. At the same time, researchers are studying promising new therapies in clinical trials. These experimental treatments aim to target the root causes of inflammation more precisely than older medications.^[7][13]

Because nasal polyps often grow back even after surgery, finding the right long-term treatment strategy is essential. Many people need a combination of approaches to keep their symptoms under control. Working closely with your doctor—whether an allergist or an ear, nose, and throat specialist—helps ensure you receive personalized care that addresses your specific needs.^[2][11]

Standard Medical Treatments

The cornerstone of treating chronic rhinosinusitis with nasal polyps starts with medications that reduce inflammation and help your nasal passages drain properly. These treatments don’t cure the condition, but they can control symptoms and improve your daily comfort.^[7]

Intranasal corticosteroid sprays are the first-line treatment recommended for nearly everyone with nasal polyps. These sprays work directly on the inflamed tissue inside your nose to reduce swelling. Common options include fluticasone, budesonide, mometasone, and beclomethasone. You typically spray them once or twice daily into each nostril. While they’re generally safe and inexpensive, some people experience mild side effects like nosebleeds, burning, or stinging sensations. For smaller polyps, these sprays can be very effective, but they may not work as well if your polyps are large.^[2][11][12]

A newer delivery system called a breath-powered corticosteroid device delivers medication deeper into the nasal passages than traditional sprays. This approach may help the medication reach areas where polyps commonly form, potentially improving treatment results.^[2][11]

Saline nasal irrigations are strongly recommended alongside corticosteroid sprays. These rinses use saltwater to flush out mucus, allergens, and irritants from your nasal passages. You can use a squeeze bottle, neti pot, or other irrigation device. The water must be distilled, sterile, or previously boiled and cooled to avoid infection. Saline rinses improve mucus flow and help you breathe better. Studies have shown they significantly improve symptoms in people with chronic rhinosinusitis.^[2][7][11]

Oral corticosteroids are sometimes prescribed for short courses, typically up to three weeks, when symptoms flare up severely or when nasal sprays alone aren’t enough. These pills work throughout your body to reduce inflammation more powerfully than nasal sprays. They can shrink polyps and relieve symptoms fairly quickly. However, they can cause side effects like weight gain, mood changes, increased blood sugar, weakened bones, and higher infection risk. Because of these risks, doctors limit how often and how long you take them.^[7][12][13]

Some doctors may prescribe antibiotics for up to three weeks if they suspect a bacterial infection is making your chronic condition worse. However, antibiotics don’t treat the underlying inflammation, so they’re not used as routine maintenance therapy. They’re reserved for acute flare-ups where infection is clearly present.^[7][13]

Treatment duration varies from person to person. Nasal sprays and saline rinses are typically used long-term as maintenance therapy to keep symptoms controlled. You may need to continue them indefinitely to prevent polyps from growing back. Your doctor will monitor your progress and adjust your treatment plan based on how well you respond.^[7][12]

Surgical Treatment

Endoscopic sinus surgery becomes an option when medications don’t adequately control your symptoms. During this procedure, a surgeon uses a thin tube with a camera to see inside your nose and sinuses. They remove polyps and open blocked sinus passages to improve drainage. This surgery is usually done as an outpatient procedure, meaning you go home the same day.^[2][7]

While surgery can provide significant relief, it doesn’t address the underlying inflammation that causes polyps to form. This is why polyps often grow back. Studies show that approximately forty percent of patients who have surgery see their polyps return within a few years. This is why continued medical treatment after surgery is so important.^[5][6]

Biologic Therapies: A New Approach

In recent years, a new class of medications called biologics has changed how doctors treat chronic rhinosinusitis with nasal polyps. These are not traditional drugs but rather specialized proteins created through advanced laboratory techniques. They work by targeting specific parts of the immune system that drive inflammation.^[9][15]

Biologics are different from corticosteroids because they aim at the root cause of inflammation rather than just dampening it broadly. Most nasal polyps in Western countries are driven by what scientists call type 2 inflammation. This is a specific pattern of immune system activity involving certain proteins called cytokines and cells called eosinophils. When these become overactive, they cause the tissue in your nose to swell and form polyps.^[5][15]

The inflammation often starts in the epithelium, which is the thin layer of cells lining your nasal passages. This barrier is your first defense against dust, pollen, and other irritants you breathe in every day. In people with nasal polyps, certain proteins released by these cells—including thymic stromal lymphopoietin, interleukin-25, and interleukin-33—trigger a cascade of inflammatory reactions that lead to polyp formation and symptoms.^[5]

Approved Biologic Options

Three biologic medications have been approved by the U.S. Food and Drug Administration specifically for treating chronic rhinosinusitis with nasal polyps in adults whose disease isn’t controlled with nasal corticosteroids. These are dupilumab, mepolizumab, and omalizumab.^[13][15]

Dupilumab blocks the receptors for interleukin-4 and interleukin-13, two proteins that play key roles in type 2 inflammation. By blocking these signals, dupilumab prevents the inflammatory cascade from progressing. It’s given as an injection under the skin every two weeks. Clinical trials called LIBERTY NP SINUS-24 and LIBERTY NP SINUS-52 tested dupilumab in patients with nasal polyps. These Phase 3 trials showed that dupilumab significantly reduced nasal polyp size, improved nasal congestion, restored sense of smell, and reduced the need for oral steroids and surgery. Some patients noticed improvement in nasal congestion as early as three days after starting treatment, though this was not the main focus of the studies.^[15][16]

Mepolizumab targets interleukin-5, a protein that helps produce and activate eosinophils. These white blood cells accumulate in nasal polyp tissue and drive inflammation. By reducing eosinophil levels, mepolizumab decreases the inflammation that causes symptoms. It’s also given as an injection, typically once every four weeks. The SYNAPSE trial, a Phase 3 study, demonstrated that mepolizumab reduced nasal polyp size, improved symptoms, and decreased the need for surgery or systemic steroids.^[6][15]

Omalizumab works by binding to immunoglobulin E, an antibody involved in allergic reactions and inflammation. People with nasal polyps often have high levels of this antibody in their nasal tissue. Omalizumab prevents immunoglobulin E from triggering inflammatory reactions. It’s administered by injection, with dosing and frequency determined by your weight and immunoglobulin E level. Two Phase 3 trials, POLYP 1 and POLYP 2, showed that omalizumab improved nasal symptoms and reduced polyp size in patients who weren’t adequately controlled with nasal corticosteroids.^[15]

Studies comparing these biologics indirectly suggest that dupilumab may be particularly effective at reducing nasal congestion and polyp size, but all three medications show meaningful benefits. The choice between them often depends on whether you have other conditions like asthma, your insurance coverage, and how frequently you prefer to receive injections.^[9][15]

How Biologics Are Used

Biologics are prescribed as add-on maintenance treatments, meaning you continue using your nasal corticosteroid sprays while also receiving biologic injections. They’re typically reserved for people whose symptoms remain uncontrolled despite optimal medical therapy, or for those who have had multiple surgeries with polyps growing back each time.^[6][14][15]

Most biologics can be self-administered at home after you receive proper training from your healthcare provider. This convenience allows you to maintain treatment without frequent office visits. The injections are given subcutaneously, meaning just under the skin, similar to how people with diabetes give themselves insulin.^[14][16]

Common side effects of biologics include injection site reactions like redness, swelling, or pain. Headache, back pain, and fatigue have also been reported. Some people develop infections, including herpes zoster, which causes shingles. Serious allergic reactions are rare but possible, and can occur hours or days after an injection. Symptoms include facial swelling, breathing problems, dizziness, rash, or hives. If you experience these symptoms, seek emergency medical help immediately.^[6][14]

Biologics in Clinical Development

Researchers continue to explore additional biologic therapies for nasal polyps. Several medications are being tested in clinical trials but are not yet approved. These include benralizumab, which targets the alpha receptor for interleukin-5; reslizumab, another anti-interleukin-5 therapy; etokimab, which blocks interleukin-33; and tezepelumab, which targets thymic stromal lymphopoietin.^[15]

These experimental therapies are being evaluated in different phases of clinical trials. Phase 1 trials test whether a new drug is safe and determine the right dose. Phase 2 trials examine whether the drug works effectively to improve symptoms or reduce disease severity. Phase 3 trials compare the new drug against current standard treatments in larger groups of patients. Results from some of these trials are still pending publication, so we don’t yet know how effective they might be.^[9][15]

Clinical trials for nasal polyps are conducted in many countries, including the United States, Poland, and other European nations. To participate, patients typically need to meet certain criteria, such as having persistent symptoms despite using nasal corticosteroids, having polyps of a certain size, and not having certain other medical conditions. If you’re interested in clinical trials, ask your doctor whether any are enrolling patients in your area.^[9]

Living with Chronic Rhinosinusitis with Nasal Polyps

Beyond medical treatments, making certain lifestyle changes can help reduce symptom flares and improve your comfort. Avoiding triggers that irritate your nasal passages is an important part of managing this condition. Tobacco smoke is one of the most common irritants, so staying away from cigarette smoke—whether you smoke or are around smokers—can make a significant difference. Chemical fumes from cleaning products, paint, or industrial environments can also worsen inflammation. Using incense or being around dust and debris may trigger symptoms as well.^[2][11]

Some people with nasal polyps find that taking aspirin or nonsteroidal anti-inflammatory drugs like ibuprofen or naproxen sodium makes their symptoms worse. This is related to a condition called aspirin-exacerbated respiratory disease. If you notice your symptoms worsen after taking these medications, discuss alternatives with your doctor.^[2][11]

Many people with nasal polyps also have asthma, and the two conditions can influence each other. Inflamed sinuses from nasal polyps can make asthma harder to control. On the other hand, treating your nasal polyps effectively can improve your asthma symptoms. Working with both an allergist and potentially an ear, nose, and throat specialist ensures you receive coordinated care for both conditions.^[2][11]

Loss of smell is one of the most distressing symptoms for many people. This can affect your ability to enjoy food, recognize danger like smoke or gas leaks, and even impact your emotional well-being and relationships. Some people experience complete loss of smell, called anosmia, while others have reduced smell, called hyposmia. Effective treatment that reduces inflammation can help restore this important sense, though recovery may take time.^[5][6][19]

The chronic nature of this condition can also affect mental health. Living with constant nasal congestion, frequent sinus infections, and diminished quality of life can lead to frustration, anxiety, and even depression. Some patients report feeling misunderstood by friends, family, and even healthcare providers who may not fully grasp how debilitating the symptoms can be. Seeking support from patient communities or mental health professionals can be helpful if you’re struggling emotionally.^[19][22]

Working with Your Healthcare Team

Getting the right diagnosis and treatment often requires working with multiple specialists. Your primary care doctor may refer you to an allergist or an ear, nose, and throat specialist. Sometimes these doctors collaborate to provide comprehensive care. An allergist can test whether allergies are contributing to your symptoms and help manage asthma if you have it. An ENT specialist can perform procedures like nasal endoscopy to visualize your polyps and may perform surgery if needed.^[2][11]

Diagnosis typically involves both symptom assessment and objective evidence. Your doctor will ask about symptoms like nasal congestion, runny nose, postnasal drip, facial pressure, and loss of smell lasting more than twelve weeks. They’ll also perform a physical examination, often using a thin tube with a camera called an endoscope to look inside your nose. Imaging tests like computed tomography scans may show the extent of sinus involvement and polyp size. Allergy testing can identify triggers that might be making your condition worse.^[2][7][11]

Open communication with your healthcare providers is essential. Share how your symptoms affect your daily life, including your ability to work, sleep, taste food, or enjoy activities. Discuss your treatment preferences, concerns about side effects, and any challenges you face following your treatment plan. This shared decision-making approach helps ensure you receive care that fits your individual needs and improves your chances of successful symptom control.^[19]
