What is Dulera (Formoterol Fumarate + Mometasone Furoate) 5mcg/200mcg inhaler?

Dulera 5mcg/200mcg is indicated for controlling and preventing asthma symptoms, including wheezing, in adults and adolescents 12 years of age and older. It is a prescription inhaler that combines two active ingredients: formoterol fumarate and mometasone furoate. It is primarily used for the maintenance treatment of asthma.

Formoterol fumarate is a long-acting beta-agonist (LABA) bronchodilator that helps relax the muscles in the airways, making breathing easier. It works by stimulating beta-2 receptors in the smooth muscles of the airways, leading to bronchodilation and improved airflow.

Mometasone furoate is a corticosteroid that acts as an anti-inflammatory agent. It helps to reduce inflammation in the airways, thereby decreasing symptoms such as wheezing, coughing, and shortness of breath associated with asthma.

By combining formoterol fumarate and mometasone furoate in a single inhaler, Dulera provides both bronchodilation and anti-inflammatory effects, making it a convenient option for asthma management. It is typically used regularly to prevent asthma symptoms and should not be used as a rescue inhaler for sudden asthma attacks.

NDC code is 0085-7206

Clinical Pharmacology

The mechanism of action of Dulera involves the combined effects of its two active ingredients.

Formoterol fumarate (a long-acting beta-agonist) stimulates beta-2 adrenergic receptors in the smooth muscles of the airways. This leads to the relaxation of the bronchial muscles, resulting in bronchodilation and improved airflow. By opening up the airways, formoterol helps to alleviate symptoms such as wheezing and shortness of breath associated with asthma.

Mometasone furoate (an inhaled corticosteroid) is an anti-inflammatory medication that works by inhibiting the release of inflammatory mediators and reducing the recruitment and activation of inflammatory cells in the airways. It helps to decrease swelling and inflammation in the airway tissues, reducing the frequency and severity of asthma symptoms.

This combination helps to control asthma and maintain optimal lung function.

Ingredients

The components of the medication are the following:

  • Mometasone furoate – 200 mcg;
  • Formoterol fumarate dihydrate – 5 mcg.

What Are the Dosages of Dulera (Formoterol Fumarate + Mometasone Furoate)?

The standard dosage for a Dulera (Formoterol Fumarate + Mometasone Furoate) inhaler with a strength of 5mcg/200mcg per actuation is as follows.

For patients 12 years of age and older:

  • The recommended starting dose is 1 inhalation twice daily (morning and evening), for a total daily dose of 2 inhalations.
  • The maximum recommended daily dose is 2 inhalations twice daily, for a total daily dose of 4 inhalations.

The dosage may vary depending on individual factors, such as the severity of asthma and the patient’s response to treatment. Therefore, it’s essential to follow the specific instructions your healthcare professional provides or as indicated on the prescription label. They will determine the appropriate dosage based on your unique condition and adjust it if necessary.

It’s crucial to use Dulera regularly as prescribed, even if you are not experiencing symptoms. Stay within the recommended dosage unless instructed by your healthcare provider.

To properly use the Dulera inhaler, follow these general steps:

  1. Remove the cap from the mouthpiece and shake the inhaler well. Check the dose counter to ensure that enough doses are remaining.
  2. Breathe out completely, away from the inhaler, to ensure your lungs are empty before inhaling the medication.
  3. Hold the inhaler in a level, horizontal position with the mouthpiece facing you, and place your thumb on the base of the inhaler. Make sure your fingers are not covering the vents.
  4. Take a slow, deep breath through your mouth, and as you inhale, press down firmly on the top of the inhaler to release the dose. Continue inhaling steadily and deeply to ensure the medication reaches your lungs.
  5. After inhaling, remove the inhaler from your mouth and hold your breath for about 10 seconds, or as long as comfortable, to allow the medication to deposit in your airways.
  6. Breathe out slowly and gently away from the inhaler.
  7. Rinse your mouth with water without swallowing after using the inhaler to minimize the risk of oral thrush or other mouth and throat irritation. Spit out the water.
  8. Replace the cap on the mouthpiece to protect it until your subsequent use.

It’s essential to read and follow the specific instructions provided with your Dulera inhaler, as there may be slight variations in usage. 

Important Safety Information

Dulera is not a rescue inhaler and should not be used for sudden asthma attacks or worsening symptoms. Always keep a fast-acting bronchodilator inhaler (e.g., albuterol) for immediate relief.

Like other long-acting beta-agonists (LABAs), formoterol (an active ingredient in Dulera) may increase the risk of asthma-related death. It is essential to use this medication exactly as prescribed and follow your healthcare professional’s instructions.

Mometasone furoate (an active ingredient) is a corticosteroid. Prolonged use of high doses may increase the risk of adrenal insufficiency, growth retardation in children, and other systemic effects. Use the lowest effective dose and follow your healthcare professional’s recommendations.

Rarely, hypersensitivity reactions, including anaphylaxis, angioedema, and rash, have been reported with this inhaler. Seek medical attention immediately if you experience difficulty breathing, swelling, or severe rash after using the medication.

Dulera may worsen certain medical conditions, including glaucoma, osteoporosis, diabetes, cardiovascular disorders, and immune system suppression. Inform your healthcare professional about your medical history before using this inhaler.

Also, inform your healthcare professional about all medications you are taking, including prescription, over-the-counter drugs, and herbal supplements. Certain medications may interact with this one, leading to increased side effects or reduced effectiveness.
