Drug InteractionsMometasone/formoterol can potentially interact with certain other medications (see Drug Interactions With Mometasone/Formoterol for more information).
Overdose InformationAs with any medication, it is possible to take too much mometasone/formoterol. If you happen to overdose on this medication, seek immediate medical attention.

What Should I Do If I Miss a Dose of Mometasone/Formoterol?If you forget to take a dose of mometasone/formoterol, simply skip your missed dose and continue with your regular dosing schedule. Do not take a double dose.
How Does It Work?Normally, air moves into and out of the lungs easily through a network of airways. When you have asthma, the inside walls of your airways are inflamed or swollen. This inflammation makes the airways sensitive, and they tend to react strongly to things that you are allergic to or find irritating (see Asthma Triggers).
When the airways react, the muscles around them tighten, inflammation inside the airways increases, and cells inside them produce more mucus. As a result, the airways become narrow, making it difficult to breathe.
Mometasone/formoterol is an asthma medication that contains a combination of two other asthma medications:
- Mometasone (Asmanex®) -- an inhaled corticosteroid
- Formoterol fumarate (Foradil®) -- a long-acting, beta-adrenergic agonist.
Inhaled corticosteroids, sometimes called steroids for short, reduce the inflammation in the lungs that lead to asthma symptoms, such as wheezing and shortness of breath.
Beta-adrenergic agonists, or beta agonists for short, relax the muscles around the airways, opening the airways up and allowing air to get into and through the lungs more easily. Because mometasone/formoterol contains a long-acting beta agonist, it does not work quickly. Therefore, it is used to control asthma symptoms, not to treat asthma attacks once they start.
