Mometasone is used to control and prevent symptoms (wheezing and shortness of breath) caused by asthma. This medication must be used regularly to be effective. It does not work right away and should not be used to relieve sudden asthma attacks. If an asthma attack occurs, use your quick-relief inhaler (such as albuterol, also called salbutamol in some countries) as prescribed.
Mometasone belongs to a class of drugs known as corticosteroids. It works by reducing the irritation and swelling of the airways. Controlling symptoms of breathing problems can decrease time lost from work or school.
OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.
Read the Patient Information Leaflet provided by your pharmacist before you start using this medication and each time you get a refill. Follow the illustrated directions for the proper use of this medication and proper cleaning of the mouthpiece. If you have any questions, consult your doctor or pharmacist.
Inhale this medication by mouth as directed by your doctor, usually once or twice a day. Do not breathe out (exhale) into the inhaler. The dosage is based on your medical condition, age, and response to treatment.
If two inhalations/puffs are prescribed, wait at least one minute between them. If you are using other inhalers at the same time, wait at least 1 minute between the use of each medication, and use this drug (the corticosteroid) last.
Use this medication regularly in order to get the most benefit from it. This medication works best if used at evenly spaced intervals. To help you remember, use it at the same time(s) each day. Do not increase your dose, use this medication more frequently, or stop using it without first consulting your doctor.
Always have your quick-relief inhaler with you. Keep track of the number of inhalations you use. The inhaler should be discarded when every inhalation has been used (when the dose indicator reads ''00'') or if it has been 45 or 60 days (depending on your brand) after removal from its foil overwrap pouch, whichever comes first.
If you are regularly using a different corticosteroid taken by mouth (such as prednisone), you should not stop using it unless directed by your doctor. You may have withdrawal symptoms if the drug is suddenly stopped. Some conditions (such as asthma, allergies) may become worse when the drug is suddenly stopped. To prevent withdrawal symptoms (such as weakness, weight loss, nausea, muscle pain, headache, tiredness, dizziness), your doctor may direct you to slowly lower the dose of your old medication after you begin using this product. Consult your doctor or pharmacist for more details, and report any withdrawal reactions right away. See also Precautions section.
It may take 1-2 weeks before you get the full benefit of this drug. Tell your doctor if your symptoms do not improve or if they worsen.
Learn which of your inhalers you should use every day (controller drugs) and which you should use if your breathing suddenly worsens (quick-relief drugs). Ask your doctor ahead of time what you should do if you have new or worsening cough or shortness of breath, wheezing, increased sputum, worsening peak flow meter readings, waking up at night with trouble breathing, if you use your quick-relief inhaler more often (more than 2 days a week), or if your quick-relief inhaler does not seem to be working well. Learn when you can treat sudden breathing problems by yourself and when you must get medical help right away.

If you have switched from a corticosteroid taken by mouth (such as prednisone tablets) to this inhaler within the past 12 months, or if you have been using this product in higher-than-usual doses for a long time, it may be more difficult for your body to respond to physical stress. Therefore, before having surgery or emergency treatment, or if you get a serious illness/injury, tell your doctor or dentist that you are using this medication or have used a corticosteroid taken by mouth within the past 12 months. Tell your doctor right away if you develop unusual/extreme tiredness or weight loss. Carry a warning card or medical ID bracelet that says you use (or have used) corticosteroid medications.
Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).
This medication may mask signs of infection. It can make you more likely to get infections or may worsen any current infections. Therefore, wash your hands well to prevent the spread of infection. Avoid contact with people who have infections that may spread to others (such as chickenpox, measles, flu). Consult your doctor if you have been exposed to an infection or for more details.

Learn to use a peak flow meter and use it daily. Promptly report worsening asthma (such as readings in the yellow or red range, or increased use of quick-relief inhalers) to your doctor.
Laboratory and/or medical tests (such as lung function tests, morning cortisol levels, eye exam, bone density tests) should be performed periodically to monitor your progress or check for side effects. Consult your doctor for more details.
Avoid allergens/irritants such as smoke, pollen, pet dander, dust, or molds that may worsen breathing problems. Because the flu virus can also worsen breathing problems, ask your doctor or pharmacist if you should have a flu shot every year.
