Dulera is an inhaled medication that helps prevent bronchospasm in patients with asthma. It contains a combination of two drugs: mometasone is a steroid that reduces inflammation, and formoterol is a bronchodilator that relaxes muscles in the airways. Dulera is meant to control the symptoms of asthma, but should not be used as a rescue medication in emergency situations.
Always follow your doctor’s instructions and use Dulera exactly as prescribed.
Steroids like mometasone can weaken your immune system. Avoid coming into contact with people who are sick or have an infection, and tell your doctor if you develop an illness or infection.
Long-term use of Dulera can cause osteoporosis, especially in people who are inactive, smokers, or don’t get enough vitamin D or calcium.
Before taking Dulera, inform your doctor if you have any of the following:
Common side effects of Dulera include:
Contact your doctor if you experience these more serious side effects:
Can I use Dulera in the event of an asthma attack?
No. Dulera is not a rescue medication, and will not help in the event of an asthma attack.
What if I miss a dose of Dulera?
If you’ve missed a dose of Dulera, wait until your next regularly scheduled dose. Do not take two doses at once to make up for the missed dose.
Can I use a spacer with Dulera?
Yes. Using a spacer may make it easier for Dulera to reach the lungs, and leads to less medication in the mouth and throat. Talk to your doctor about proper spacer technique.
