Chronic sinusitis is frustratingly persistent, but a combination of daily nasal care, targeted medications, and sometimes surgery can bring lasting relief. The condition is defined by at least 12 consecutive weeks of symptoms, so “getting rid of it” usually means a sustained, layered treatment approach rather than a single fix. Most people start with nasal steroid sprays and saline rinses, then escalate to stronger options if those aren’t enough.
What Makes It Chronic
A diagnosis of chronic sinusitis (formally called chronic rhinosinusitis) requires at least two of four cardinal symptoms lasting 12 weeks or more: nasal obstruction, facial pain or pressure, discolored nasal drainage, and reduced sense of smell. Nasal obstruction is the most common, affecting 81% to 95% of patients. Facial pressure shows up in 70% to 85%, followed by discolored drainage (51% to 83%) and smell loss (61% to 69%).
Unlike acute sinus infections that clear up with time or a short course of antibiotics, chronic sinusitis involves ongoing inflammation in the sinus lining. It can exist with or without nasal polyps, which are soft, painless growths inside the nasal passages. The presence of polyps changes the treatment strategy significantly, so getting a proper evaluation with nasal endoscopy or a CT scan matters before committing to a plan.
Saline Rinses: The Foundation
Daily saline nasal irrigation is one of the most effective things you can do at home. It physically flushes out mucus, allergens, and inflammatory debris from the sinus cavities. Guidelines recommend it as a frontline treatment alongside nasal steroid sprays. You can use a squeeze bottle, neti pot, or powered irrigator.
Water safety is critical. The CDC warns that people have died from rinsing their sinuses with tap water containing dangerous organisms like Naegleria fowleri. Always use store-bought distilled or sterile water, or boil your tap water at a rolling boil for one minute (three minutes above 6,500 feet elevation) and let it cool before use. If none of those options are available, you can disinfect water with unscented household bleach: about 5 drops per quart for bleach with 4% to 5.9% sodium hypochlorite concentration, then let it stand for at least 30 minutes.
Nasal Steroid Sprays
Prescription and over-the-counter nasal corticosteroid sprays are the cornerstone medication for chronic sinusitis. They reduce inflammation directly in the sinus lining, and relief can begin within 3 to 12 hours of the first dose, though full benefit builds over days to weeks of consistent use. The typical regimen is one to two sprays in each nostril once or twice daily, depending on the specific product.
Several options are available over the counter, including fluticasone propionate and triamcinolone. The key is consistency. Using a nasal steroid spray for a few days and stopping won’t make a dent in chronic inflammation. Most people need to use them daily for weeks or months, and many benefit from long-term maintenance use. Proper technique also matters: aim the spray toward the outer wall of your nostril rather than straight up or toward the center of your nose.
When Antibiotics Help (and When They Don’t)
Antibiotics are not a standard treatment for chronic sinusitis. Current guidelines emphasize saline irrigation and nasal corticosteroids as the go-to therapies. Antibiotics are primarily recommended for acute bacterial sinus infections, where a typical course runs 5 to 10 days with amoxicillin as the first choice.
Some doctors prescribe longer antibiotic courses for chronic cases when there’s evidence of active bacterial infection, but this remains controversial. Overusing antibiotics for a condition driven primarily by inflammation rather than infection can do more harm than good. If your symptoms haven’t improved with standard treatments, the next step is usually a closer look at the underlying cause rather than another round of antibiotics.
Short-Term Oral Steroids
For flare-ups or severe symptoms, a short course of oral corticosteroids (typically up to 14 days) can provide meaningful relief, especially for people with nasal polyps. These work systemically to tamp down inflammation throughout the sinuses. Side effects during a short burst can include insomnia, mood changes, and stomach discomfort like heartburn or nausea.
The catch is that repeated short courses or prolonged use carries real risks, including weakened bones over time. Oral steroids work well as a temporary reset, but they’re not a sustainable long-term solution. They’re most useful as a bridge while you establish other treatments or prepare for surgery.
Reducing Environmental Triggers
Chronic sinus inflammation doesn’t happen in a vacuum. What you breathe every day plays a direct role. Research from Johns Hopkins found that mice exposed to polluted air for 16 weeks developed significantly more inflammatory cells in their sinus tissue compared to mice breathing filtered air. The polluted air also broke down protective proteins in the sinus lining, potentially making the sinuses more vulnerable to allergens, viruses, and bacteria.
Practical steps that reduce your exposure include running a HEPA air purifier in your bedroom, keeping indoor humidity between 30% and 50% to discourage mold and dust mites, fixing water leaks promptly, and avoiding wood-burning stoves or fireplaces. If you have known allergies to dust mites, pet dander, or mold, managing those triggers with allergen-proof bedding covers, regular vacuuming, and mold remediation can meaningfully reduce the inflammatory load on your sinuses.
Sinus Surgery
When medications and nasal rinses aren’t enough, surgery becomes a realistic option. The two main procedures are functional endoscopic sinus surgery (FESS) and balloon sinuplasty. Both are performed through the nostrils with no external incisions.
FESS involves removing small amounts of bone and tissue to widen the sinus drainage pathways. Balloon sinuplasty uses an inflatable catheter to stretch open blocked sinuses without removing tissue. A 2025 meta-analysis comparing the two found that balloon sinuplasty had slightly better patient-reported symptom scores after surgery and shorter operating times. Revision surgery rates were statistically similar between the two approaches. One study within the analysis found that 55.6% of balloon sinuplasty patients recovered normal smell, compared to 33.3% of FESS patients.
Surgery is not a permanent cure for everyone. For patients with nasal polyps, five-year recurrence rates are around 30%, and ten-year recurrence rates reach roughly 66%. This means ongoing medical management after surgery, including nasal steroid sprays and saline rinses, is essential to maintain the benefits. Surgery opens the pathways; daily maintenance keeps them open.
Biologic Therapies for Nasal Polyps
If you have chronic sinusitis with nasal polyps that keep coming back despite surgery and steroid treatment, biologic medications represent a newer option. Three are currently approved for this condition: dupilumab, omalizumab, and mepolizumab. These are injectable medications that target specific parts of the immune response driving polyp growth, particularly a pattern of inflammation involving certain immune signaling molecules that promote swelling, mucus overproduction, and tissue growth in the sinuses.
Biologics can shrink polyps, improve breathing and smell, and reduce the need for oral steroids and repeat surgeries. They’re given as injections, typically every two to four weeks. They’re generally reserved for moderate to severe cases that haven’t responded adequately to other treatments, partly because of their cost. For the right patient, though, they can be transformative, turning a cycle of surgeries and steroid bursts into stable, manageable disease.
Putting a Treatment Plan Together
Getting rid of chronic sinusitis typically means layering treatments and sticking with them. Start with twice-daily saline rinses using safe water and a daily nasal steroid spray. Give this combination at least 8 to 12 weeks of consistent use before judging whether it’s working. Address environmental triggers in your home during that time.
If symptoms persist, imaging and possibly nasal endoscopy can reveal what’s going on structurally. A short oral steroid course can help clarify whether your inflammation is steroid-responsive, which guides the next steps. Surgery opens blocked pathways and removes polyps, but it works best when paired with ongoing medical therapy afterward. For polyp-driven disease that keeps recurring, biologics offer a way to control the underlying immune dysfunction rather than just managing symptoms on the surface.
