Mometasone belongs to the class of medications called corticosteroids. Mometasone inhalation is used to treat asthma in people 4 years of age and older. It helps to control the symptoms of asthma and prevent asthma attacks by reducing the swelling in the airways of the lungs. When used regularly, it will help prevent and control asthma symptoms. It will not relieve an asthma attack once it has already started. Regular daily use is important for its effectiveness.
This medication starts to work within 24 hours, but the full effects may not be seen until 1 to 2 weeks.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
Your doctor may increase or decrease the dose, depending on how well it works for you. Once the breathing difficulties are under control, the dose should be decreased to the lowest possible dose that keeps the asthma under control. If asthma worsens while using this medication, your doctor may instruct you to increase the dose or use the medication more frequently.
The amount of powder inhaled with each dose is very small. You may not be able to taste it or feel in going into your lungs. However, the medication will be getting into your lungs if you follow the instructions on how to use the inhaler. If you are not sure how to use your inhaler, ask your pharmacist or doctor to show you.
Treatment with this medication should not be stopped abruptly. It should be tapered off gradually to reduce the chance of the symptoms worsening.
To reduce the risk of thrush (yeast) infection in the mouth, rinse and gargle with water after inhaling the medication.
It is important to remember that this medication will not provide immediate relief for an asthma attack that has already started. This medication is intended for long-term relief. Inhalers that contain "reliever" medications with fast action (e.g., salbutamol, terbutaline) will still be needed while using this medication on a regular basis.
This medication works best when it is used regularly. It is important to take this medication exactly as prescribed by your doctor. If you miss a dose, skip the missed dose and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Asthma control: This medication is not for use as a "reliever" medication. If you start to have an asthma attack, be sure to use your "reliever" medication for rapid relief of your asthma symptoms. Contact your doctor immediately if you find you are using your "reliever" medications (e.g., salbutamol, terbutaline, formoterol) more often or if they are not working as well as they used to. This may mean your asthma is not controlled. Your doctor may want you to temporarily change the dose of this medication or may start you on an oral corticosteroid.
Eye problems: Prolonged use of mometasone or other inhaled corticosteroids may cause glaucoma with possible damage to the optic nerves or it may produce cataracts. It may also increase the risk of eye infections due to fungi or viruses. You should discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Infections: Mometasone may hide some signs of infection, and new infections may appear while mometasone is being used. Infections such as chickenpox and measles can be more serious in people taking medications such as mometasone. Contact your doctor if you notice any symptoms of an infection (e.g., fever, chills, cough, sore throat), or if you are in contact with someone who has measles or chickenpox.
Liver function: Mometasone may have increased effects on people who have cirrhosis of the liver. If you have reduced liver function or liver disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Oral hygiene: Adequate oral hygiene, such as rinsing your mouth with water after using this medication, helps reduce the chances of developing thrush, a yeast (fungal) infection of the mouth or throat. If you develop symptoms of thrush, such as white patches in your mouth, contact your doctor.
Osteoporosis: Over time, this medication can increase the risk of osteoporosis (brittle bones), just as any corticosteroid can. Talk to your doctor about ways to help prevent osteoporosis. Your doctor will monitor your bone density if you need to take this medication for a long period of time.
Steroid medication use: If you have taken or are still taking an oral steroid medication (e.g., prednisone) during the last several months, consult your doctor before using this medication. In times of stress or during a severe asthma attack, your doctor may want you to start your steroid medication again.
Stopping medication: Do not stop this medication abruptly. When this medication is stopped, it should be stopped gradually, as directed by your doctor.
Thyroid disease: The effects of mometasone may be increased for people with decreased thyroid function (hypothyroidism). If you have hypothyroidism, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if mometasone passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: Inhaled mometasone may slow the growth and development of adolescents using this medication. This will be closely monitored by your child’s doctor. The safety and effectiveness of inhaled mometasone has not been determined for children less than 4 years of age.
