What is Dulera?

Dulera inhalers contain a combination of formoterol and mometasone. Formoterol is a long-acting bronchodilator that relaxes muscles in the airways to improve breathing.

Mometasone is a corticosteroid. It prevents the release of substances in the body that cause inflammation.

Dulera is used as a maintenance treatment for asthma in adults and children who are at least 12 years old.

Dulera inhaler is not for use in treating an asthma or bronchospasm attack.

Important Information

Dulera is not a rescue medicine. It will not work fast enough to treat an asthma or bronchospasm attack.

Formoterol when used alone may increase the risk of death in people with asthma. However, this risk is not increased when formoterol and mometasone are used together as a combination product.

Seek medical attention if your breathing problems get worse quickly, or if you think your asthma medications are not working as well.

Before taking this medicine

You should not use Dulera if you are allergic to formoterol (Foradil, Perforomist, Symbicort) or mometasone (Asmanex).

Mometasone can weaken your immune system, making it easier for you to get an infection or worsening an infection you already have or have recently had. Tell your doctor about any illness or infection you have had within the past several weeks.

To make sure Dulera is safe for you, tell your doctor if you have ever had:

Long-term use of steroids may lead to bone loss (osteoporosis), especially if you smoke, if you do not exercise, if you do not get enough vitamin D or calcium in your diet, or if you have a family history of osteoporosis. Talk with your doctor about your risk of osteoporosis.

It is not known whether Dulera will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

It is not known whether formoterol and mometasone passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

Dulera is not approved for use by anyone younger than 12 years old.

How should I use Dulera?

Dulera inhalers come with patient instructions for safe and effective use, and directions for priming the inhaler device. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.

Do not use Dulera in larger or smaller amounts or for longer than recommended. Using too much of this medicine can cause life-threatening side effects. Tell your doctor if you think your medications are not working as well.

Dulera is not a rescue medicine. It will not work fast enough to treat an asthma attack. Use only a fast-acting inhalation medicine for an asthma attack.

Shake the Dulera inhaler for at least 5 seconds before each use.

Rinse your mouth with water after each use of your inhaler.

It may take up to 1 week before your symptoms improve. Keep using Dulera as directed and tell your doctor if your symptoms do not improve after 1 week of treatment.

If you also use an oral steroid medication, you should not stop using it suddenly. Follow your doctor's instructions about tapering your dose.

Your dose needs may change if you have surgery, are ill, are under stress, or have recently had an asthma attack. Do not change your medication dose or schedule without your doctor's advice.

Seek medical attention if your breathing problems do not improve, or if your symptoms get worse quickly. If you use a peak flow meter at home, call your doctor if your numbers are lower than normal.

Store Dulera inhalers at room temperature away from moisture and heat.

The 120-inhalation Dulera inhaler does not require specific storage orientation. For the 60-inhalation Dulera inhaler, after priming, store the inhaler with the mouthpiece down or on its side. Keep the medicine canister away from open flame or high heat, such as in a car on a hot day. The canister may explode if it gets too hot. Do not puncture or burn an empty inhaler canister.
