About nasal polyps

What are nasal polyps?

Nasal polyps are soft, non-cancerous (also called “benign”) growths that develop as a result of chronic sinus inflammation.

Symptoms of nasal polyps:

Runny nose/nasal discharge

Impact of nasal polyps

Nasal polyp symptoms often make it difficult to breathe and reduce sense of smell, impacting everyday life.

Nasal polyp symptoms, such as nasal discharge and nasal congestion, can hinder and decrease enjoyment in daily activities, and leave patients feeling embarrassed in social situations.

As nasal polyps grow in size and number, they can become large enough to block the nasal passages.

The cycle of traditional nasal polyp treatments

Nasal polyp symptoms are often treated with saline rinses and steroid sprays in the nose. However, these treatments must be used daily and don’t always provide relief because it’s difficult for the medicine to reach the polyps. Steroid sprays may be available as generics.

Oral steroids are also commonly prescribed for nasal polyp symptoms, and are also available as generics. While steroids have been shown to be effective in treating symptoms, oral steroids don’t specifically target nasal polyps. This means the steroids may circulate in the whole body and with repeated use may cause serious safety concerns, such as high blood sugar levels, infections, bone loss, adrenal suppression, and eye complications.

Biologics may also be used for nasal polyps. Biologics are injectable medications, which means that the medication may circulate in your whole body, not just at the nasal polyps. These can also be an expensive option in your treatment journey.

Since traditional treatments may not provide enough symptom relief, patients may be trapped in a cycle of going from one medicine to another as they try to control their symptoms.

When your current medicines are not enough, the cycle of medical interventions may continue with sinus surgery

Nasal polyps develop as a result of chronic sinus inflammation. Symptom relief often requires endoscopic sinus surgery, also referred to as ESS, after medicines fail. Even though endoscopic sinus surgery is performed half a million times a year in the United States, and symptoms may be temporarily relieved, repeat surgery is often needed as sinus surgery is not a cure.

When nasal polyps come back after sinus surgery, repeat sinus surgery is sometimes needed. This shows how important it is to have nonsurgical targeted nasal polyp treatment options

SINUVA Sinus Implant is a prescription steroid-releasing (mometasone furoate) implant indicated for the treatment of nasal polyps in patients 18 years or older who have had ethmoid sinus surgery.


Who should not use SINUVA?

Do not use SINUVA if you are allergic to mometasone furoate or any ingredients of the implant.

What should I tell my doctor before receiving SINUVA?

Before you receive SINUVA, tell your doctor about all medical conditions you have including nasal/sinus problems (such as nasal ulcers or trauma), eye problems (such as glaucoma or cataracts), or any untreated fungal, bacterial, or viral infections.

What are the possible side effects of SINUVA?

Serious side effects of SINUVA can include:

  • Local reactions including nosebleed and injury to nerves or blood vessels in the nose/sinus.

  • Serious allergic reactions have happened in patients using mometasone furoate including rash, itching or swelling of the lips, face, tongue, and throat, and breathing problems. Call your doctor right away if you have any of these reactions.

  • Weakened immune system that may increase your risk of infections. Avoid contact with people who have contagious diseases such as chickenpox or measles. Call your doctor right away if you have been near someone with chickenpox or measles.

  • Adrenal insufficiency
    is a condition in which the adrenal glands do not make enough steroid hormones and can cause tiredness, weakness, nausea and vomiting and low blood pressure. Talk to your doctor if steroid effects such as Cushing Syndrome and adrenal suppression appear.

The most common side effects of SINUVA in clinical studies were bronchitis, cold symptoms, middle ear infections, headache, lightheadedness or dizziness, asthma, and nosebleeds. The following side effects have been identified during post-approval use of the SINUVA sinus implant. These events include implant migration, lack of efficacy, nasal pain, headache, and nosebleeds.

Tell your doctor if you have any side effects that bother you or don’t go away.

Risks related with the insertion and removal of SINUVA are similar to other endoscopic sinus procedures.

SINUVA is made from materials designed to soften over time and may fall out of the nose on its
own as polyps decrease or if you sneeze or blow your nose forcefully. The implant will be removed 90 days after placement or earlier at your doctor’s discretion.

Contact your doctor immediately if you have any changes in vision, excessive nasal bleeding, symptoms of infection or symptoms suggesting that the implant has moved, such as irritation or a choking sensation in the back of the throat.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit, or call 1-800-FDA-1088.
