Before using Dulera Inhaler, discuss your complete medical history with your healthcare provider. This helps ensure the medication is safe and appropriate for you.
Do Not Exceed the Recommended Dose
Use Dulera exactly as prescribed. Taking more than the recommended dose or using it more often than directed can increase the risk of serious side effects, including heart-related problems and excessive exposure to corticosteroids. Do not use additional inhalers containing a long-acting betaâ‚‚-adrenergic agonist (LABA) while using Dulera unless specifically instructed by your healthcare provider.
Not for Sudden Asthma Attacks
Dulera is a maintenance inhaler designed to help control asthma over time. It does not work quickly enough to relieve sudden asthma symptoms or asthma attacks. Always carry a fast-acting rescue inhaler to treat sudden wheezing, chest tightness, or shortness of breath.
Paradoxical Bronchospasm
In rare cases, Dulera may cause paradoxical bronchospasm, a condition in which breathing suddenly becomes worse immediately after using the inhaler. Symptoms may include severe wheezing, coughing, or difficulty breathing. This reaction can be life-threatening and requires immediate medical attention. Stop using Dulera and seek emergency medical care if this occurs.
Increased Risk of Infections
Because mometasone is an inhaled corticosteroid, Dulera may weaken your immune system and make it harder to fight infections. Tell your healthcare provider if you have:
- Active or inactive tuberculosis (TB).
- A fungal, bacterial, viral, or parasitic infection.
- Recently been exposed to chickenpox or measles.
- A weakened immune system for any reason.
Contact your healthcare provider if you develop signs of an infection, such as fever, chills, sore throat, or persistent cough.
Eye Problems
Long-term use of inhaled corticosteroids, including the mometasone in Dulera, may increase the risk of developing cataracts or glaucoma. Tell your healthcare provider if you have a history of these eye conditions or other steroid-related eye problems. Regular eye examinations may be recommended during long-term treatment.
Adrenal Suppression
Using inhaled corticosteroids for prolonged periods or at high doses may lead to adrenal suppression, a condition in which the adrenal glands do not produce enough cortisol. Inform your healthcare provider if you have a history of adrenal gland disorders or have recently switched from oral corticosteroids to Dulera. Symptoms of adrenal insufficiency may include severe fatigue, weakness, dizziness, nausea, vomiting, or low blood pressure.
Allergic Reactions
Do not use Dulera if you are allergic to mometasone, formoterol, or any of the other ingredients in the inhaler. Seek immediate medical attention if you experience symptoms of a serious allergic reaction, such as rash, hives, swelling of the face, lips, tongue, or throat, or difficulty breathing.
Tell Your Healthcare Provider About Your Medical History
Before starting Dulera, let your healthcare provider know if you have any medical conditions, especially:
- Tuberculosis or other infections.
- Glaucoma, cataracts, or other eye disorders.
- Adrenal gland disorders.
- Heart disease or high blood pressure.
- Diabetes.
- Thyroid disorders.
- Seizures.
- Liver disease.
- Osteoporosis or low bone mineral density.
- A weakened immune system.
Also provide a complete list of all medications you take, including prescription medications, over-the-counter products, vitamins, and herbal supplements, since some medicines may interact with Dulera or increase the risk of side effects.
