Dulera

Dulera (mometasone / formoterol) includes a steroid medication. When inhaled through the mouth, it can cause a fungal infection in your mouth and throat called thrush. To lower your risk for thrush, make sure to rinse your mouth with water and spit after each inhalation of Dulera (mometasone / formoterol). If you develop thrush, your provider might still ask you to continue Dulera (mometasone / formoterol). Sometimes, they might prescribe you a medication to treat this condition. Let your provider know if you notice symptoms of thrush, such as white patches in your mouth, cotton-like feeling in your mouth, pain while eating or swallowing, or loss of taste.

Inhaled medications, including Dulera (mometasone / formoterol), can sometimes cause a muscle spasm in your lungs (bronchospasm). This can lead to difficulty breathing, wheezing, cough, and chest discomfort. If you have a hard time breathing after inhaling Dulera (mometasone / formoterol), use your rescue inhaler and get medical attention right away.

Like all corticosteroid-containing medications, Dulera (mometasone / formoterol) can weaken your immune system and raise your risk for infections. And if you do get sick, this medication can make it harder for you to heal. Your risk for infections is higher if you're also taking other medications that also weaken your immune system. If you're currently being treated for a serious infection, such as tuberculosis, let your provider know. They might need to consider a different medication for your asthma. Let your provider know right away if you have symptoms of infections, such as fever, chills, body aches.

Using Dulera (mometasone / formoterol) for long periods of time or at a dose that's higher than recommended can cause more medication to be absorbed into the body. This can affect your body in different ways since the medication acts similar to cortisol (a natural stress hormone made by your body). You might experience symptoms of too much cortisol (called Cushing's disease), such as weight gain around your gut, puffiness of your face, and muscle weakness in the arms and legs.

It's possible for children to experience a delay in growth during treatment with Dulera (mometasone / formoterol). Children should use the lowest dose for the shortest amount of time needed. Your child's provider will check their growth regularly while they're receiving this medication. If you're concerned about how Dulera (mometasone / formoterol) might affect your child's growth, discuss with your child's provider to see if this medication is right for them.

Though rare, people taking Dulera (mometasone / formoterol) have reported having higher pressure in the eyes, glaucoma, and cataracts. Talk to your eye provider before using Dulera (mometasone / formoterol) if you have glaucoma or cataracts because they might ask you to come in more often for eye exams. Also speak with them if you notice any changes to your vision while using the medication.
