mometasone furoate
Read all of this leaflet carefully before you start using this medicine because it contains important information for you.
Contents of the pack
Asmanex Twisthaler contains the active substance mometasone furoate, which belongs to a group of medicines called corticosteroids or simply steroids.
Corticosteroids should not be confused with “anabolic” steroids, which are used improperly by some athletes. Corticosteroids are used to prevent asthma attacks as they have an anti-inflammatory effect. They reduce inflammation and irritation of the walls of the small airways in the lungs. This helps to make breathing easier.
Asmanex Twisthaler is used regularly to control asthma in adults and adolescents from 12 years of age. It can be given if you have not used a corticosteroid before and your asthma is not controlled with other medicines. It can also be used to control your asthma if you have been taking a different corticosteroid by mouth or by inhalation. Used regularly, Asmanex Twisthaler will help to control your asthma and prevent asthma attacks. It is a “preventive” medicine. Do not use it in a sudden asthma attack. You should always carry the bronchodilator (“reliever” inhaler) that your doctor has prescribed, just in case you have an asthma attack.
Do not use Asmanex Twisthaler

Important things to remember when using Asmanex Twisthaler

Other medicines and Asmanex Twisthaler
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including those obtained without a prescription. This includes medicines to treat fungal or viral infections, such as ketoconazole, itraconazole, ritonavir, nelfinavir or cobicistat. These medicines may increase the amount of corticosteroid in your blood.
Some medicines may increase the effects of Asmanex Twisthaler, so your doctor will monitor you closely if you are taking these medicines.
It is also important that you tell your doctor before you start using Asmanex Twisthaler if you are taking other corticosteroids, by injection, orally or by inhalation. Your doctor will tell you how to adjust the dose of these other corticosteroids.
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.
Driving and using machines
Asmanex Twisthaler does not affect your ability to drive or use machines.
Asmanex Twisthaler contains lactose
It may cause allergic reactions in patients with cow's milk protein allergy.
If your doctor has told you that you have an intolerance to some sugars, consult with them before using this medicine.
This medicine contains a small amount of lactose (4.64 mg/day in the maximum recommended daily dose). This amount normally does not cause problems in people with lactose intolerance.
Make sure you know how to use your inhaler properly. Avoid dropping the inhaler as it may break. If you have any problems, consult your doctor or pharmacist. Make sure you know when and how many doses to inhale. Your doctor should have told you and the instructions are in the package leaflet. Follow your doctor's or pharmacist's instructions exactly. Do not change the dose unless your doctor tells you to.If in doubt, consult your doctor or pharmacist again.
For adults (including those over 65 years of age) and adolescents over 12 years of age with mild to moderate asthma, the recommended initial dose is 400 micrograms (1 dose or inhalation) once daily in the evening, using Asmanex Twisthaler 400 micrograms inhalation powder. However, for some patients, the initial dose may be 200 micrograms (1 dose or inhalation) twice daily, using Asmanex Twisthaler 200 micrograms inhalation powder. If your asthma is controlled, your doctor may reduce the dose to 200 micrograms (1 dose or inhalation) once daily in the evening. Depending on your symptoms, your doctor may increase or decrease your daily dose to keep your asthma under control.
For patients with severe asthma who may be taking other corticosteroids, in tablet or syrup form, the usual initial dose of Asmanex Twisthaler is 400 micrograms twice daily, which is the highest recommended dose. After about one week of treatment with Asmanex Twisthaler, your doctor may start to slowly reduce the dose of the other corticosteroid and eventually stop it altogether. Then, if your asthma is well controlled, it may be possible to reduce the dose of Asmanex Twisthaler.
Instructions for proper use of the inhaler
Remember that Asmanex Twisthaler produces a very fine powder that you must inhale into your lungs. You should be standing when using your inhaler. To get the correct dose, follow these instructions carefully.
Before removing the white cap, make sure the counter and the arrow on the cap are aligned. To open the inhaler, remove the white cap. Hold the inhaler in an upright position, with the pink base down. Hold it by the base and twist the cap counterclockwise to remove it. When you remove the cap, the dose counter on the inhaler will decrease by one unit.
Make sure the counter on the pink base and the arrow above the counter are aligned with each other. Hold the inhaler upright once the cap is removed and before inhaling your dose.

Remove cap Inhale Close inhaler Inhaler closed
Once you have finished taking your dose, rinse your mouth with water or with a mouthwash and then spit it out without swallowing. This will help prevent thrush.
Keep your inhaler clean and dry at all times. Clean the outside of the mouthpiece with a dry cloth or tissue. Do not wash the inhaler; avoid contact with water.
On the base of the inhaler, there is a window with a counter that shows the number of doses left in the inhaler. Do not use Asmanex Twisthaler if you notice that the counter is not working correctly. Take it to your doctor or pharmacist.
When “01” appears in the counter window, it means that there is only one dose left in the inhaler. After inhaling the 01 dose, “00” will appear on the counter, the cap will be locked, and no further doses can be obtained from the inhaler. In this situation, discard the inhaler.
To ensure that you always have enough medication, have your doctor prescribe a new one before the inhaler you are using runs out.
The time to relief of symptoms varies between subjects. Although some patients experience an improvement within 24 hours of starting treatment, others may not obtain the maximum benefit until one to two weeks or more. Your doctor will tell you how long you should continue using Asmanex Twisthaler.

Like all medicines, this medicine can cause side effects, although not everybody gets them.
Stop using Asmanex Twisthaler and tell your doctor immediately if you notice any of the following symptoms:
Symptoms of a severe allergic reaction including swelling of the eyes, face, lips, mouth, tongue or throat which may cause difficulty in swallowing or breathing, skin rash with itching, feeling of fainting and dizziness which may cause fainting.
If you notice an increase in coughing, wheezing, difficulty breathing or shortness of breath immediately after inhaling the medicine, use your “reliever” inhaler and contact your doctor immediately. Do not use Asmanex Twisthaler again until you have seen your doctor.
Allergic reactions (hypersensitivity) to inhaled corticosteroids can occur. If this happens, you may notice skin rash, itching and redness and swelling of the eyes, face, lips and throat. If you get any of these symptoms, tell your doctor immediately. Do not use Asmanex Twisthaler again until you have seen your doctor.
The most frequently reported side effects include thrush (white patches) in the mouth or throat, hoarseness, sore throat or headache. Consult your doctor as soon as possible if you develop any of these side effects.
Other uncommon side effects (affecting less than 1 in 100 patients) may include dryness of the mouth and throat, indigestion, weight gain and rapid or strong heartbeats (palpitations). Contact your doctor if you notice any of these symptoms.
In rare cases (affecting less than 1 in 1,000 patients), patients taking inhaled corticosteroids, including Asmanex Twisthaler, have developed increased eye pressure (including glaucoma) or cataracts.
Frequency not known (cannot be estimated from the available data): blurred vision.
Contact your doctor if you have blurred vision or eye pain.
Other possible side effects of corticosteroids are slowing or alteration of growth rate in adolescents and a decrease in bone mineral density. They can also cause sleep disturbances, depression or feeling of worry, restlessness, nervousness, excitability or irritability with the use of inhaled corticosteroids. There is a greater likelihood that these effects will occur in children. Corticosteroids can also affect the functioning of your adrenal gland, causing weakness, tiredness or dizziness, as well as fainting when standing for a long time or when getting up from a sitting position. It is much less likely that these effects will occur with the use of inhaled corticosteroids than with the use of oral corticosteroids.
