Mometasone Furoate Information
(moe met' a sone)
- Remove the cap from the mouthpiece.
- If you are using the inhaler for the first time or if you have not used the inhaler in more than 5 days, prime it by releasing 4 test sprays into the air, away from your face. Be careful not to spray the medication into your eyes or face. Shake the inhaler prior to each inhalation.
- Breathe out through your mouth.
- Hold the inhaler facing you with the mouthpiece on the bottom. Place your thumb under the mouthpiece and your index finger on the center of the dose indicator at the top of the canister. Place the mouthpiece in your mouth and close your lips around it.
- Breathe in deeply and slowly through your mouth. At the same time, press down firmly on the center of the dose indicator at the top of the canister with your index finger. Remove your index finger as soon as the spray is released.
- When you have breathed in fully, remove the inhaler from your mouth and close your mouth.
- Try to hold your breath for about 30 seconds, then breathe out gently.
- If your doctor has told you to take more than one puffs per treatment, repeat steps 3 through 7.
- Put the cap back on the mouthpiece.
- Rinse your mouth with water and spit the water out. Do not swallow the water.
- Clean your aerosol inhaler once a week. To clean your inhaler, use a clean, dry tissue or cloth. Do not wash or put any part of your inhaler in water.
- If you are using a new inhaler for the first time, remove it from the foil pouch. Write the date that you opened the inhaler in the space provided on the cap label.
- Hold the inhaler straight up with the colored base on the bottom. Twist the white cap counterclockwise and remove it. This loads the correct amount of medication in the base of the inhaler, so it is important to twist the cap and not twist the base with your hand. As you lift the cap off, the dose counter on the base will count down by one to show the number of doses left after this use.
- Breathe out fully.
- Hold the inhaler on its side with the mouthpiece facing you. Be sure that you are not covering the ventilation holes on the sides of the inhaler. Place the mouthpiece of the inhaler in your mouth and close your lips firmly around it.
- Breathe in a fast, deep breath. You will receive your medication as a very fine powder, so you may not be able to smell, feel, or taste it as you inhale.
- Remove the inhaler from your mouth and hold your breath for 10 seconds or as long as you comfortably can. Do not breathe out into the inhaler.
- Wipe the mouthpiece dry. Put the cap back onto the inhaler so that the indented arrow is in line with the dose counter. Gently press down and turn clockwise until you hear a click.
- Rinse your mouth with water and spit. Do not swallow the water.
Before using mometasone oral inhalation,
- tell your doctor and pharmacist if you are allergic to mometasone, any other medications, or any of the ingredients in mometasone inhalation powder or aerosol inhaler. If you will be using the inhalation powder, also tell your doctor if you are allergic to milk proteins. Ask your pharmacist for a list of the ingredients.
- tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or have recently taken. Be sure to mention any of the following: antifungals such as itraconazole (Onmel, Sporanox) and ketoconazole (Nizoral); clarithromycin (Biaxin); HIV protease inhibitors such as atazanavir (Reyataz, in Evotaz), indinavir (Crixivan), nelfinavir (Viracept), ritonavir (Norvir, in Kaletra, in Viekira Pak, others), and saquinavir (Invirase); medications for seizures, nefazodone; oral steroids such as dexamethasone, methylprednisolone (Medrol), and prednisone (Rayos); and telithromycin (Ketek). Your doctor may need to change the doses of your medications or monitor you carefully for side effects. Many other medications may also interact with mometasone oral inhalation, so be sure to tell your doctor about all the medications you are taking, even those that do not appear on this list.
- do not use mometasone during an asthma attack. Your doctor will prescribe a short-acting inhaler to use during asthma attacks. Call your doctor if you have an asthma attack that does not stop when using the fast-acting asthma medication, or if you need to use more of the fast-acting medication than usual.
- tell your doctor if you or anyone in your family has or has ever had osteoporosis (a condition in which the bones become thin and weak and break easily) and if you have or have ever had tuberculosis (TB; a type of lung infection) in your lungs, cataracts (clouding of the lens of the eye), glaucoma (an eye disease) or high pressure in the eye, or liver disease. Also tell your doctor if you have any type of untreated infection anywhere in your body or a herpes eye infection (a type of infection that causes a sore on the eyelid or eye surface), or if you are on bedrest or unable to move around.
- tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant while using mometasone inhalation, call your doctor.
- if you are having surgery, including dental surgery, tell the doctor or dentist that you are using mometasone inhalation.
- if you have any other medical conditions, such as asthma, arthritis, or eczema (a skin disease), they may worsen when your oral steroid dose is decreased. Tell your doctor if this happens or if you experience any of the following symptoms during this time: extreme tiredness, muscle weakness or pain; sudden pain in stomach, lower body or legs; loss of appetite; weight loss; upset stomach; vomiting; diarrhea; dizziness; fainting; depression; irritability; and darkening of skin. Your body may be less able to cope with stress such as surgery, illness, severe asthma attack, or injury during this time. Call your doctor right away if you get sick and be sure that all healthcare providers who treat you know that you recently replaced your oral steroid with mometasone inhalation. Carry a card or wear a medical identification bracelet to let emergency personnel know that you may need to be treated with steroids in an emergency.
- tell your doctor if you have never had chickenpox or measles and you have not been vaccinated against these infections. Stay away from people who are sick, especially people who have chickenpox or measles. If you are exposed to one of these infections or if you develop symptoms of one of these infections, call your doctor right away. You may need treatment to protect you from these infections.
- you should know that mometasone inhalation sometimes causes wheezing and difficulty breathing immediately after it is inhaled. If this happens, use your fast-acting (rescue) asthma medication right away and call your doctor. Do not use mometasone inhalation again unless your doctor tells you that you should.
