Read the Medication Guide that comes with DULERA® before you start using it and each time you get a refill. There may be new information. This Medication Guide does not take the place of talking to your healthcare provider about your medical condition or treatment.

What is the most important information I should know about DULERA?

DULERA can cause serious side effects, including:

1.

People with asthma who take long-acting beta2-adrenergic agonist (LABA) medicines such as formoterol (one of the medicines in DULERA), have an increased risk of death from asthma problems. It is not known whether mometasone furoate, the other medicine in DULERA, reduces the risk of death from asthma problems seen with formoterol.

• Call your healthcare provider if breathing problems worsen over time while using DULERA. You may need different treatment.
• Get emergency medical care if:
  • breathing problems worsen quickly, and
  • you use your rescue inhaler medicine, but it does not relieve your breathing problems.

2.

DULERA should be used only if your healthcare provider decides that your asthma is not well controlled with a long-term asthma control medicine, such as an inhaled corticosteroid.

3.

When your asthma is well controlled, your healthcare provider may tell you to stop taking DULERA. Your healthcare provider will decide if you can stop DULERA without loss of asthma control. Your healthcare provider may prescribe a different long-term asthma-control medicine for you, such as an inhaled corticosteroid.

4.

Children and adolescents who take LABA medicines may have an increased risk of being hospitalized for asthma problems.

What is DULERA?

DULERA combines an inhaled corticosteroid medicine, mometasone furoate (the same medicine found in ASMANEX TWISTHALER), and a long-acting beta2-agonist medicine (LABA), formoterol (the same medicine found in FORADIL® AEROLIZER®).

• Inhaled corticosteroids help to decrease inflammation in the lungs. Inflammation in the lungs can lead to asthma symptoms.
• LABA medicines are used in people with asthma. LABA medicines help the muscles around the airways in your lungs stay relaxed to prevent asthma symptoms, such as wheezing and shortness of breath. These symptoms can happen when the muscles around the airways tighten. This makes it hard to breathe. In severe cases, wheezing can stop your breathing and may lead to death if not treated right away.

DULERA is used to control symptoms of asthma and prevent symptoms such as wheezing in people 12 years of age and older.

DULERA should not be used as a rescue inhaler.

DULERA contains formoterol (the same medicine found in FORADIL AEROLIZER). LABA medicines such as formoterol increase the risk of death from asthma problems.

DULERA is not for children and adults with asthma who:

• are well controlled with an asthma-control medicine, such as a low to medium dose of an inhaled corticosteroid medicine
• only need a rescue inhaler once in awhile

It is not known if DULERA is safe and effective in children less than 12 years of age.

Who should not use DULERA?

Do not use DULERA:

• to treat sudden severe symptoms of asthma
• if you are allergic to any of the ingredients in DULERA. See the end of the Medication Guide for a list of ingredients in DULERA.

What should I tell my healthcare provider before using DULERA?

Tell your healthcare provider about all of your health conditions, including if you:

• have heart problems
• have high blood pressure
• have seizures
• have thyroid problems
• have diabetes
• have liver problems
• have osteoporosis
• have an immune system problem
• have eye problems such as increased pressure in the eye, glaucoma, or cataracts
• are allergic to any medicines
• are exposed to chickenpox or measles
• have any other medical problems
• are pregnant or planning to become pregnant. It is not known if DULERA may harm your unborn baby.
• are breastfeeding. It is not known if DULERA passes into your milk and if it can harm your baby. You and your healthcare provider should decide if you will take DULERA while breastfeeding.

Tell your healthcare provider about all the medicines you take including prescription and non-prescription medicines, vitamins, and herbal supplements. DULERA and certain other medicines may interact with each other. This may cause serious side effects.

Especially, tell your healthcare provider if you take antifungal medicines, such as ketoconazole, or anti-HIV medicines, such as ritonavir. The anti-HIV medicines NORVIR® (ritonavir capsules) Soft Gelatin, NORVIR® (ritonavir oral solution), and KALETRA® (lopinavir/ritonavir) Tablets contain ritonavir.

Know the medicines you take. Keep a list and show it to your healthcare provider and pharmacist each time you get a new medicine.

How should I use DULERA?

See the step-by-step instructions for using DULERA at the end of this Medication Guide. Do not use DULERA unless your healthcare provider has taught you and you understand everything. Ask your healthcare provider or pharmacist if you have any questions.

• Use DULERA exactly as prescribed. Do not use DULERA more often than prescribed. DULERA comes in 2 strengths. Your healthcare provider has prescribed the strength that is best for you. Note the differences between DULERA and your other inhaled medications, including the differences in prescribed use and physical appearance.
• DULERA should be taken every day as 2 puffs in the morning and 2 puffs in the evening.
• If you miss a dose of DULERA, skip your missed dose and take your next dose at your regular time. Do not take DULERA more often or use more puffs than you have been prescribed.
• While you are using DULERA 2 times each day, do not use other medicines that contain a long-acting beta2-agonist (LABA) for any reason. Ask your healthcare provider or pharmacist if any of your other medicines are LABA medicines.
• If you take more DULERA than your healthcare provider has prescribed, get medical help right away if you have any unusual symptoms, such as problems breathing, palpitations, chest pain, increased heart rate, nervousness or shakiness.
• Do not change or stop using DULERA or other asthma medicines used to control or treat your breathing problems unless told to do so by your healthcare provider. Your healthcare provider will change your medicines as needed.
• DULERA does not relieve sudden asthma symptoms. Always have a rescue inhaler with you to treat sudden symptoms. Use your rescue inhaler if you have breathing problems between doses of DULERA. If you do not have a rescue inhaler, call your healthcare provider to have one prescribed for you.
• Remove the cap from the mouthpiece of the actuator before using DULERA.
• Rinse your mouth with water after each dose (2 puffs) of DULERA. This will help to lessen the chance of getting a yeast infection (thrush) in the mouth and throat.
• Do not spray DULERA in your eyes. If you accidentally get DULERA in your eyes, rinse your eyes with water and if redness or irritation continues, call your healthcare provider.
• Call your healthcare provider or get medical care right away if:
  • your breathing problems worsen with DULERA
  • you need to use your rescue inhaler more often than usual
  • your rescue inhaler does not work as well for you at relieving symptoms
  • you need to use 4 or more inhalations of your rescue inhaler for 2 or more days in a row
  • you use 1 whole canister of your rescue inhaler in 8 weeks' time
  • your peak flow meter results decrease. Your healthcare provider will tell you the numbers that are right for you.
  • you have asthma and your symptoms do not improve after using DULERA regularly for 1 to 2 weeks

What are the possible side effects of DULERA?

DULERA can cause serious side effects, including:

• See "What is the most important information I should know about DULERA?"
• Thrush in the mouth and throat. You may develop a yeast infection (Candida albicans) in your mouth or throat. Rinse your mouth with water after using DULERA to help prevent an infection in your mouth or throat.

• Tell your healthcare provider about any signs of infection such as:
  • fever
  • feeling tired
  • pain

• Serious allergic reactions. Call your healthcare provider or get emergency medical care if you get any of the following symptoms of a serious allergic reaction:

  • increased or decreased blood pressure
  • a fast and irregular heartbeat
  • headache
  • tremor
  • nervousness
  • dizziness
  • weakness
  • seizures
