Dulera vs Advair – Uses, Dosage, Side Effects, Differences


It is the brand name of a combination of mometasone (a steroid that prevents the release of substances in the human body that cause inflammation) and formoterol (a long-acting bronchodilator that relaxes muscles in the airways to improve breathing). It is used as a maintenance treatment for asthma in children who are at least 12 years old and adults.

This drug is part of a group of medications called corticosteroids, potent group III. It was originally approved by the Food and Drug Administration in 2010. It is produced by Merck and Co., Inc., one of the largest pharmaceutical companies in the world.


It is typically used to treat asthma and improve lung function. Asthma is a chronic disease that affects the airways – the tubes which transport air into and out of the lungs. Some individuals with this condition may go for extended periods without having any signs and symptoms, however, they experience periods of asthma attacks. The most common signs of asthma include:

  • shortness of breath;
  • coughing, particularly during physical exercise, at night, or when laughing;
  • wheezing, a squeaky sound in the chest when breathing, particularly when exhaling;
  • chest tightness;
  • difficulty breathing.

There are a few factors that may trigger an asthma attack, like:

  • medications – colored/dyed pills;
  • allergens, like – pollen, pet dander, pollution, tobacco smoke, ingested allergens, dairy products, food additives, eggs, or cigarette smoke;
  • yeasts;
  • physical exercise;
  • emotional stress;
  • cold air;
  • time of day – it is typically worse at night;
  • molds;
  • temperature changes;
  • humidity;
  • hormonal changes;
  • cold symptoms, like – an upper respiratory tract infection.

In a study that lasted 6 months, study participants experienced:

  • reduced number of nights waking up to use an inhaler;
  • reduced use of a rescue inhaler to treat the symptoms;
  • considerable improvement in lung function.

Note – this drug is not for use in treating an asthma attack. However, if you experience an asthma attack, use your quick-relief inhaler as prescribed.


The usual recommended daily dose is 2 inhalations two times per day. More importantly, to reduce your risk of getting a yeast infection in the throat and mouth, rinse your mouth with clean water after taking a dose of this medicine.

Dulera vs Advair – Differences

Dulera (active ingredients – formoterol and mometasone) is an inhaled medicine that is typically used to control and prevent asthma symptoms, like – wheezing, in people 12 years and older.

Advair (active ingredients – salmeterol and fluticasone) is approved to prevent airway spasms due to asthma as well as to treat these spasms in individuals with COPD (chronic obstructive pulmonary disease). The two active ingredients are part of a group of drugs called bronchodilators. These drugs relax the muscles in the walls of the small air passages in the lungs.

Natural Remedies for Asthma Treatment

#1 Quit Smoking

Smoking tobacco makes asthma symptoms worse, plus, it triggers asthma attacks more frequently. Also, you should avoid second-hand smoking.

#2 Physical Exercise

Excessive physical activity is a common asthma trigger. Symptoms typically start in the first five minutes of physical exercise and then subside about half an hour later.

#3 Omega 3

Essential fatty acids, like omega-3, reduce inflammation and alleviate attacks. Foods rich in omega 3 fatty acids include – flax seeds, chia seeds, walnuts, broccoli, red kidney beans, navy beans, pinto beans, almonds, hazelnuts, and chickpeas.

#4 Onion & Garlic

They are high in a potent anti-inflammatory compound called quercetin which helps relieve allergies.

#5 Dark Green Leafy Vegetables

They are quite useful for asthma patients due to their high antioxidant content.
