What are the possible side effects of Dulera in children?

The possible side effects of the asthma medication Dulera (mometasone and formoterol) in children are similar to those in adults. Dulera is prescribed for treating asthma in people ages 12 and older. Children and teens who take Dulera may be at greater risk of being hospitalized while taking Dulera than adults, and the drug may cause slowed growth in some children. Your child's doctor may monitor your child closely during treatment with Dulera.

Dulera contains two active ingredients for treating asthma. Mometasone is an inhaled corticosteroid that reduces airway swelling and inflammation. Formoterol belongs to a class of drugs called long-acting beta-agonists, or LABAs, that relax and open the airways. People with asthma who take LABAs have an increased risk of death from asthma. Call the doctor if your child's asthma symptoms worsen when taking Dulera, and call 911 if your child's breathing problems worsen quickly and/or a rescue inhaler doesn't relieve your child's breathing problem.

The most common side effects of Dulera are headaches and swelling and irritation of the nose, throat and/or sinuses. Other side effects are less common but may be more serious. Call for medical help immediately if your child experiences symptoms of allergic reaction, such as rash, hives, trouble breathing or swelling of the face, mouth or tongue. Call your doctor as soon as possible to report these side effects:
  • signs of oral thrush, including white patches in the mouth or on the tongue, cracking at the corners of the mouth, redness or soreness in the 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 girls), 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 or headache
Over time, Dulera may cause these other problems:
  • reduced bone mineral density
  • eye problems, including cataracts and glaucoma. Your child's doctor may recommend more frequent eye exams during treatment with Dulera.
  • decreases in blood potassium levels (hypokalemia)
  • increases in blood sugar levels (hyperglycemia)
