This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information.

Take this medication exactly as prescribed by your doctor. Follow the directions on your prescription label carefully.

• Serious allergic reactions. Call your health care provider or get emergency medical care if you get any symptoms of a serious allergic reaction, including:
  • Rash
  • Swelling of the face, mouth and tongue
  • Breathing problems
• Possible increased risk of infection due to a weakened immune system with using steroid medicines. Tell your health care provider if you or your child have or had TB, are exposed to anyone with chickenpox or measles, or about any other infections you or your child had before or while using Asmanex Twisthaler.
• Adrenal insufficiency (your adrenal gland cannot produce enough steroids since you were on oral steroid medicine). If you or your child took steroids by mouth and are having them decreased (tapered) or you are being switched to Asmanex Twisthaler, you should be followed closely by your health care professional.
  Death can occur. Tell your health care professional right away about any symptoms such as feeling tired or exhausted, weakness, nausea, vomiting, or symptoms of low blood pressure (such as dizziness or faintness). If you or your child is under stress, such as with surgery, after surgery or trauma, you may need steroids by mouth again.
• Decreased bone mass (bone mineral density). Patients who use inhaled steroid medicines for a long time may have an increased risk of decreased bone mass, which can affect bone strength. Talk with your health care provider about any questions about bone health.
• Lower bone mineral density. This may be a problem for people who already have a higher chance for low bone density (osteoporosis).
• Slowed growth in children. A child's growth should be checked often.
• Eye problems including glaucoma and cataracts. You should have regular eye exams while using Asmanex Twisthaler.
• Increased wheezing right after taking Asmanex Twisthaler. Always have a rescue inhaler with you to treat sudden wheezing.

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Asmanex Twisthaler falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.

Tell your doctor if you are breastfeeding or planning to breastfeed.

It is not known whether Asmanex Twisthaler crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using Asmanex Twisthaler. 

Wash your hands after applying mometasone cream, lotion or ointment.

Mometasone inhalation is not used to treat an asthma attack (sudden episode of shortness of breath, wheezing, and coughing) that has already started. Mometasone inhalation helps to prevent asthma attacks but will not stop an asthma attack that has already started.
