Proper Usage

Take Dulera precisely according to prescription instructions. Do not take Dulera more frequently than instructed.

Evey day, take two puffs of Dulera in the morning and two puffs in the evening.

Do not stop using Dulera unless your doctor tells you that you should stop.

If you have missed a dose of Dulera, skip the missed dose and take your next dose at your regular time. Do not use Dulera more often than instructed by your doctor.

Prime the actuator with the inhaler pointed away from your face. Make sure you never spray Dulera in your eyes.

After each dose (two puffs) of Dulera, thoroughly rinse your mouth with water and spit the water out without swallowing. Taking this step will help to reduce the possibility of developing thrush.

Dosage and Strength Options

There are two dosage strengths:

  • 60-actuation inhaler (100 mcg/5 mcg)
  • 120-actuation inhaler (200 mcg/5 mcg)

Both dosages should be taken as two puffs in the morning and two puffs in the evening.

Potential Side Effects and Risks

The side effects most frequently experienced by patients taking Dulera include headache and inflammation of the sinuses, throat and nose.

Other possible side effects include:

  • Higher chance of infection. Symptoms of infection may include body aches, fever, pain, nausea and vomiting.

Drug Interactions

While you are using Dulera, do not use other medicines that contain a long-acting beta2-agonist for any reason. Ask your pharmacist or physician to verify that none of your other medications are LABA medicines.

Tell your doctor about any antifungal medicines you may use, including ketoconazole, or anti-HIV medicines, such as ritonavir and cobicistat-containing products.

Keep your doctor updated regarding all the medicines you take, including over-the-counter and prescription medicines, herbal supplements and vitamins.

Carry a list of the medicines you take and review it with your pharmacist and healthcare practitioner each time a new medicine is prescribed.


Patients diagnosed with asthma and taking formoterol or other long-acting beta2-adrenergic agonist medicines may be more likely to die because of asthma complications. The other medicine in Dulera, mometasone furoate, is not known to reduce the possibility of asthma-related death.

Youthful patients using LABA medicines are potentially more likely to require hospitalization for asthma complications.

Seek immediate medical care from an emergency facility if breathing complications become suddenly worse or are not relieved by using a rescue inhaler.

Dulera should be prescribed only if your doctor has decided that another asthma-control medicine or corticosteroid designed for extended use is not properly controlling your asthma.

Safe Storage

  • Dulera should be stored at room temperature between 68°F to 77°F (20°C to 25°C).
  • Keep Dulera and all medicines out of the reach of children.
  • The 60-actuation inhaler should be stored with the mouthpiece sideways or down.
  • The 120-actuation inhaler can be stored in any position.
  • Do not puncture the canister or use near an open flame. Temperatures in excess of 120°F may cause the canister to lose containment.
