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.
