The information below describes Dulera’s typical dosages and other details about the drug.

Dulera form

Dulera comes as a powder in a metered-dose inhaler.

Dulera strengths

Dulera comes in three strengths:

  • 50 micrograms (mcg) mometasone/5 mcg formoterol
  • 100 mcg mometasone/5 mcg formoterol
  • 200 mcg mometasone/5 mcg formoterol

Typical dosages

Typically, your doctor will start by prescribing you a low dosage. Then they’ll adjust it over time to reach the amount that’s right for you. Your doctor will ultimately prescribe the smallest dosage that provides the desired effect.

The following information describes dosages that are commonly prescribed or recommended in adults. However, be sure to use the dosage your doctor prescribes for you. Your doctor will determine the best dosage to fit your needs.

Dosage for asthma

Doctors may prescribe Dulera to treat asthma. In adults, the two strengths of Dulera used for asthma are 100 mcg/5 mcg and 200 mcg/5 mcg.

Your starting dose will likely be 2 inhalations taken by mouth twice daily.

If your doctor prescribes Dulera 100 mcg/5 mcg, they may increase your dosage after 2 weeks. In this case, they’ll recommend that you use 2 inhalations of Dulera 200 mcg/5 mcg twice daily. This is the maximum dose of Dulera that’s recommended.

For more information about your specific dosage, talk with your doctor.

Children’s dosage

Dulera is approved to treat asthma in children ages 5 years and older. The dosage for children ages 12 years and older is the same as the adult dosage. (See “Dosage for asthma” above for details.)

For children ages 5 years to less than 12 years, the recommended dosage is 2 inhalations of Dulera 50 mcg/5 mcg twice daily.

Talk with your child’s doctor if you have questions about their dosage.

Long-term treatment

Dulera is meant to be used as a long-term treatment. If you and your doctor determine that Dulera is safe and effective for you, you’ll likely use it long term.

Before you start using Dulera, your doctor will discuss your treatment plan with you.

The Dulera dosage your doctor prescribes will depend on several factors. These include:

  • your age
  • how your body responds to Dulera
  • the type and severity of the condition you’re using Dulera to treat
  • other medications you take
  • side effects you may have with Dulera

Other medical conditions you have can also affect your Dulera dosage.

Follow your doctor’s directions for how to use Dulera. This medication comes as a metered-dose inhaler. Each inhaler has a canister of medication and an actuator, which dispenses the medication as a puff. For detailed instructions and a video on how to use Dulera, see the manufacturer’s website.

After using your inhaler, rinse your mouth with water and spit it out. This reduces your risk of getting oral thrush (a fungal infection of your mouth and throat). Clean the mouthpiece of your inhaler with a dry cloth once every 7 days.

If you have questions about how to use Dulera, talk with your doctor or pharmacist.


Some pharmacies offer labels with large print, braille, or a code you scan with a smartphone to convert text to speech. If your local pharmacy doesn’t have these options, your doctor or pharmacist might be able to recommend a pharmacy that does.

If you miss a dose of Dulera, skip it and use your next scheduled dose. If you’re not sure whether you should use a missed dose or skip it, talk with your doctor or pharmacist.

To help make sure that you don’t miss a dose, try using a medication reminder. This can include setting an alarm or putting a note where you’ll see it, such as on your bathroom mirror or bedside table. You could also download a reminder app on your phone.

It’s important that you don’t use more Dulera than your doctor prescribes. For some medications, using more than the recommended amount may lead to harmful effects or overdose.
