Generic Name: mometasone (moe-MET-a-sone)
Brand Name: Asmanex Twisthaler
Mometasone powder is used for:
Preventing or reducing the frequency and seriousness of bronchial asthma attacks. It is also used in certain asthma patients when adding an inhaled corticosteroid may decrease the amount of other types of corticosteroids needed. Mometasone powder does not help during an acute asthma attack.
Mometasone powder is a corticosteroid. It works by reducing inflammation in the airways.
Do NOT use mometasone powder if:
- you are allergic to any ingredient in mometasone powder or to milk proteins
- you are having an asthma attack (eg, sudden, severe onset or worsening of asthma symptoms, such as chest tightness, cough, shortness of breath, wheezing)
Contact your doctor or health care provider right away if any of these apply to you.
Before using mometasone powder:
Some medical conditions may interact with mometasone powder. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:
- if you are pregnant, planning to become pregnant, or are breast-feeding
- if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
- if you have allergies to medicines, foods, or other substances
- if you have active or inactive tuberculosis or a positive skin test for tuberculosis
- if you have an infection of the respiratory tract, any untreated infection (fungal, bacterial, parasitic, viral), measles, chickenpox, herpes simplex in or around the eye, eczema, or if you have recently received a vaccination
- if you have increased pressure in the eye, glaucoma, cataracts, diarrhea, osteoporosis (weak bones), or a family history of osteoporosis
- if you will be confined to a bed or chair for a prolonged period of time
Some MEDICINES MAY INTERACT with mometasone powder. Tell your health care provider if you are taking any other medicines, especially any of the following:
- Anticonvulsants (eg, phenytoin) or corticosteroids (eg, prednisone) because the risk of serious side effects, such as weakened bones, may be increased
- Ketoconazole because it may increase the risk of mometasone powder's side effects
This may not be a complete list of all interactions that may occur. Ask your health care provider if mometasone powder may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
How to use mometasone powder:
Use mometasone powder as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- An extra patient leaflet is available with mometasone powder. Talk to your pharmacist if you have questions about this information.
- Hold the inhaler upright and remove the cap by twisting in a counter-clockwise direction. Exhale fully. Place the mouthpiece in your mouth and firmly close your lips around the mouthpiece. Take a fast, deep breath. You may not be able to feel or taste the medicine after you inhale it. Remove the inhaler from your mouth and hold your breath for about 10 seconds. Breathe out slowly. Do not breathe out through the inhaler.
- Gently wipe the mouthpiece dry. Replace the cap by gently pressing down and rotating the cap in a clockwise direction until a click is heard. If you do not replace the cap, your next dose will not be properly loaded.
- Rinse your mouth with water after each dose. Spit out the rinse water. This will help to decrease the risk of developing a fungal infection of the mouth from mometasone powder.
- Throw away the inhaler 45 days after opening the foil pouch or when the dose counter reads zero, whichever comes first.
- Use mometasone powder on a regular schedule to get the most benefit from it.
- Continue to use mometasone powder even if you feel well. Do not miss any doses.
- If you miss a dose of mometasone powder, use it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once.
Ask your health care provider any questions you may have about how to use mometasone powder.
Important safety information:
- Mometasone powder is for oral inhalation only. Do not get it in your eyes. If you get it in your eyes, rinse right away with cool water.
- Do NOT take more than the recommended dose. If your symptoms do not get better within 2 weeks or if they get worse, check with your doctor.
- Mometasone powder will not stop an asthma attack once it has already started. Be sure to carry a short-acting bronchodilator (eg, albuterol) with you at all times to treat any breathing problems that may occur between doses of mometasone powder (eg, severe or sudden onset of wheezing, shortness of breath). If you have any questions about which medicines stop asthma attacks, check with your doctor or pharmacist.
- If you are also using a bronchodilator inhaler, be sure to always carry the bronchodilator inhaler with you to use during asthma attacks.
- Mometasone powder may sometimes cause severe breathing problems right after you use a dose. If this happens, use your short-acting bronchodilator. Contact your doctor or seek other medical care at once.
- Use caution if you switch from an oral steroid (eg, prednisone) to mometasone powder. It may take several months for your body to make enough natural steroids to handle events that cause physical stress. Such events may include injury, surgery, infection, loss of blood electrolytes, or a sudden asthma attack. These may be severe and sometimes fatal. Contact your doctor right away if any of these events occur. You may need to take an oral steroid (eg, prednisone) again. Carry a card at all times that says you may need an oral steroid (eg, prednisone) if any of these events occur.
- If your symptoms do not get better or if they get worse, check with your doctor. Do not increase the dosage.
- Contact your health care provider at once if you have an asthma attack and do not get relief from your bronchodilator inhaler.
- Mometasone powder may lower the ability of your body to fight infection. Avoid contact with people who have colds or infections. Tell your doctor if you notice signs of infection like fever, sore throat, rash, or chills.
- If you have not had chickenpox, shingles, or measles, avoid contact with anyone who does. If exposed, contact your doctor at once.
- Tell your doctor or dentist that you take mometasone powder before you receive any medical or dental care, emergency care, or surgery.
- Check with your doctor before having any vaccinations while you are using mometasone powder.
- Lab tests, including lung function, may be performed while you use mometasone powder. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
