What are the side effects of Dulera?

The most common side effects of the asthma medication Dulera (mometasone and formoterol) are swelling and irritation of the nose, throat and/or sinuses and headaches. You should call your doctor if you develop any of the following symptoms while taking Dulera:
  • signs of oral thrush including white patches in your mouth or on your tongue, cracking at the corners of your mouth, redness or soreness in your mouth or difficulty swallowing
  • signs of infection including fever, fatigue, pain, nausea, vomiting, body aches or chills
  • symptoms of adrenal insufficiency including chronic worsening fatigue, muscle weakness, loss of appetite, weight loss, salty food cravings, irregular or absent menstrual periods (in women), sweating, irritability or depression, dizziness or fainting, nausea, vomiting or diarrhea
  • increased wheezing, especially right after taking Dulera
  • symptoms caused by taking too much of a LABA medicine including chest pain, fast or irregular heartbeat, increased or decreased blood pressure, tremor, nervousness, seizures, weakness, dizziness or headache
Over time, Dulera may cause long-term side effects, and your doctor may want to monitor you closely for them. These problems may include:
  • reduced bone mineral density
  • eye problems, including cataracts and glaucoma. Follow your doctor's guidelines for getting eye exams while you are taking Dulera.
  • decreases in blood potassium levels (hypokalemia)
  • increases in blood sugar levels (hyperglycemia)
  • slowed growth (in children)
People with asthma who take LABAs have an increased risk of death from asthma. Call your doctor if your asthma symptoms worsen when you take Dulera, and call 911 if your breathing problems worsen quickly and/or your rescue inhaler doesn't relieve your breathing problem. Call for emergency medical help also if you suffer symptoms of an allergic reaction: rash, hives, trouble breathing or swelling of your face, mouth, or tongue.
