1. What is Asmanex Twisthaler and what is it used for
Asmanex Twisthaler contains the active substance mometasone furoate, which belongs to a group of medicines called corticosteroids or steroids.
Do not confuse corticosteroids with anabolic steroids, which are misused by some athletes. Corticosteroids have anti-inflammatory properties and are used to prevent asthma attacks. They reduce swelling and irritation of the airways, making it easier to breathe.
Regular use of Asmanex Twisthaler helps control asthma symptoms in adults and adolescents aged 12 and over. The medicine can be used in patients who have not previously been treated with steroids, or in those whose asthma is not controlled with other medicines. It can also be given to patients who are already taking other steroids, either orally or by inhalation, for the treatment of asthma.
Regular use of Asmanex Twisthaler helps control asthma symptoms and prevents sudden asthma attacks. The medicine is used preventively. Do not use this medicine to stop a sudden asthma attack. You should always carry a prescribed bronchodilator (inhaler that makes breathing easier) with you in case of an asthma attack.

When not to use Asmanex Twisthaler
Warnings and precautions
Before starting treatment with Asmanex Twisthaler, discuss with your doctor or pharmacist if you:
- currently have or have had tuberculosis in the past,
- have an eye infection (viral infection) or any other type of infection,
- have thrush (white patches in the mouth and throat), as you may need appropriate treatment. Your doctor may recommend stopping Asmanex Twisthaler for a while or using another inhaler. After using the medicine, rinse your mouth with water or mouthwash and spit it out, do not swallow. This can help prevent thrush.
- If you experience blurred vision or other vision disturbances, contact your doctor.
Important information to remember while using Asmanex Twisthaler
- If you experience sudden wheezing and difficulty breathing shortly after using Asmanex Twisthaler, call emergency services or go to the emergency department of the nearest hospital. These symptoms may indicate an allergic reaction to the medicine.
- Always carry a prescribed bronchodilator (inhaler that makes breathing easier) with you to quickly relieve bronchospasm or asthma attacks (coughing, wheezing, and chest tightness).
- If you experience an asthma attack that does not improve with the use of a bronchodilator (inhaler that makes breathing easier) or if your peak expiratory flow rate decreases, call emergency services or go to the emergency department of the nearest hospital. Inform your doctor, as this may indicate worsening asthma and a change in treatment may be necessary.
- In case of a severe asthma attack, other illnesses, or stress, you may need to take a steroid in the form of tablets or syrup. Your doctor may recommend that you always carry a certain amount of steroid tablets or syrup with you, along with an information card containing dosage instructions and guidelines on when to use the oral steroid.
- If you are using Asmanex Twisthaler and reducing the dose of steroids you are taking in the form of tablets or syrup, you may experience allergic reactions that have not occurred before, such as itching, excessive tearing, or rash. In this case, your doctor will recommend appropriate action to control these symptoms. If you experience joint or muscle pain, depression, fatigue, or significant slowing down during this period, inform your doctor.
- While using Asmanex Twisthaler, avoid contact with people who have chickenpox or shingles. If you come into contact with someone who has one of these illnesses, inform your doctor. This is especially important for children.
- The use of medicines like Asmanex Twisthaler may disrupt the normal production of steroids in the body. As a result, long-term treatment in adolescents may lead to growth retardation. In adolescents taking the medicine, the doctor will likely periodically monitor growth.
- All steroids, especially when used for a long time, can disrupt the function of the adrenal gland. Therefore, your doctor will regularly perform blood tests to monitor adrenal function.
- If you are going to be hospitalized, take Asmanex Twisthaler and any other medicines you are taking with you.
- Your doctor may perform lung function tests while you are using Asmanex Twisthaler, especially if you are stopping the use of oral corticosteroids.
Children and adolescents
Due to the lack of available data, Asmanex Twisthaler should not be used in children under 12 years of age.
Asmanex Twisthaler and other medicines
Tell your doctor or pharmacist about all medicines you are taking, have recently taken, or might take, including those obtained without a prescription, as well as medicines used to treat fungal or viral infections, such as ketoconazole, itraconazole, ritonavir, nelfinavir, or cobicistat. These medicines may increase the levels of mometasone furoate in your blood.
Some medicines may enhance the effect of Asmanex Twisthaler, and your doctor may want to monitor your condition closely while you are taking such medicines (including certain HIV medicines: ritonavir, cobicistat).
It is especially important to inform your doctor before starting treatment with Asmanex Twisthaler if you are taking corticosteroids, either by injection, orally, or by inhalation. Your doctor will adjust the dose of these corticosteroids.

3. How to use Asmanex Twisthaler
You must be sure that you can use the Twisthaler inhaler correctly. If you are unsure, contact your doctor or pharmacist. Before using the medicine, make sure you know when and how many doses to use. Your doctor should inform you how to use Asmanex Twisthaler. Read the instructions for using the inhaler. Always use this medicine exactly as your doctor or pharmacist has told you. If you are unsure, ask your doctor or pharmacist.
Do not change the dose of the medicine without your doctor's clear recommendation.
In adults (including those over 65 years of age) and adolescents aged 12 and over with mild or moderate asthma, the recommended initial dose is 400 micrograms (1 inhalation) once daily, in the evening.
In some patients, the initial dose may be 200 micrograms (1 inhalation of Asmanex Twisthaler 200 micrograms/dose, inhalation powder) twice daily.
If there is an improvement, your doctor may reduce the dose to 200 micrograms (1 inhalation of Asmanex Twisthaler 200 micrograms/dose, inhalation powder) once daily, in the evening.
Depending on the symptoms, your doctor may increase or decrease the daily dose to keep asthma symptoms under control.
In patients with severe asthma who may also be taking other steroids in the form of tablets or syrup, the usual initial dose of Asmanex Twisthaler is 400 micrograms twice daily. This is the maximum recommended dose. After about one week of using Asmanex Twisthaler, your doctor may recommend gradually reducing the dose of the other corticosteroid, until it is completely stopped. If asthma symptoms are well-controlled, it may also be possible to reduce the dose of Asmanex Twisthaler.

The duration of treatment with Asmanex Twisthaler will be decided by your doctor.

An allergic reaction (hypersensitivity) to inhaled steroids may occur. Symptoms include rash, itching, and redness and swelling of the eyes, face, lips, and throat. If you experience any of these symptoms, contact your doctor immediately. Do not use Asmanex Twisthaler again until you have consulted your doctor.
The most common side effects include fungal infections (thrush) of the mouth or throat (white patches appear) (very common, i.e., more than 1 in 10 people using the medicine, in the group of patients receiving 400 micrograms of mometasone furoate twice daily), hoarseness, sore throat, or headache (common, i.e., up to 1 in 10 people using the medicine, in the group of patients receiving 400 micrograms of mometasone furoate twice daily). Contact your doctor as soon as possible if you experience any of these side effects.

In patients using inhaled steroids, including Asmanex Twisthaler, rare (up to 1 in 1,000 people using the medicine) cases of increased eye pressure (including glaucoma) or cataracts have occurred.
Unknown frequency (cannot be estimated from available data): blurred vision. Contact your doctor if you experience blurred vision or eye pain.
Other side effects that may occur when using steroids include growth retardation or changes in growth rate in adolescents, and decreased bone mineral density.
